2.6 Software Accessory Alternate Lens Calibration Software

110-0133-72

For customers that furnish their own optics for use with Tau 640 cores, FLIR sells a Windows application program called Alt Lens Cal. This software enables users to perform a supplementary calibration of the camera with a lens. This field-calibration process requires the use of at least one blackbody source (a uniform, controllable temperature reference) that has an area greater than the diameter of the front of the lens.

The Alt Lens Cal software also requires a customer-furnished PC, which should be dedicated to this task. The calibration routine calculates gain terms on a per-pixel basis with the customersupplied lens attached to the Tau 640 core, and stores the customer-performed calibration in non-volatile camera memory. The original factory calibration coefficients are first uploaded from the camera and stored into a file on the PC, then the new calibration data is downloaded and stored directly into the camera. Multiple calibration files can be stored on the host computer.

The original factory calibration file can be restored if necessary, and the customer can actually build a library of lens calibration files for a Tau 640 camera. All OEM customers who add their own lenses to Tau 640 should use this program for optimal image performance.

Alternately, customers can contact FLIR to purchase a Lens Calibration feature that works with the FLIR Camera Controller GUI software. Specifically, a DLL can be added to the FLIR Camera

Controller GUI software that provides all the features of the stand-alone Alt Lens Cal software.

2.7 Software Accessory SDK for Windows & Embedded

110-0133-16

The Tau 640 Software Developer’s Kit enables camera control using one of several programming languages including VB6, VB.net, C#, and C++ (MFC). Code examples are included to help illustrate how some of the camera control functions can be used. The FLIR

Camera Controller GUI is an example of an application created using the Tau 640 SDK.

Refer to www.flir.com/cvs/cores/resources/software/tau/ .

The FLIR Camera Controller GUI remembers the last COM port that successfully communicated with a Tau 640 camera and will use that port as the default when the application starts. If the connected camera is no longer on that port, the port setting pop-up window will appear asking for you to select the proper port setting.

When the FLIR Camera Controller GUI is started, the Status tab of the utility should return data similar to the following.

Figure 3-1: FLIR Camera Controller GUI Status Tab



Step 3 Connect to your camera by selecting Connect from the

Camera

menu.


Step 4 If you want the FLIR Camera Controller GUI to automatically connect when it is started, select Settings from the Tools menu, then check the Automatically connect on

startup

box in the Settings Framework tab.

Additional settings include camera connection polling, status logging, and FLIR Veneer style.



3.5 Troubleshooting the FLIR Camera Controller GUI

If the FLIR Camera Controller GUI does not link with the camera, you may see the popup shown at the right which indicates that the GUI has not been able to communicate with the Tau 640 camera.

Verify the items in the following checklist:

Is the camera properly cabled to the host PC?:

Verify that you selected the proper port if it was not detected automatically. Select Advanced, then

Next>

in the Tools

→ Connection... dialog box. Also, try disconnecting and then re-connecting the cable to the PC. If the GUI was launched before the cable was connected, close the GUI, connect the cable, then re-launch the GUI.

Is the Baud rate set correctly?

Baud rate must be set in the Tools

→ Connection... dialog box. The Tau 640 camera supports Baud rates of 57600 and 921600.

Is the port already in use by another application?:

Shut down any other applications that may be using the port. Also, multiple instances of the FLIR

Camera Controller GUI Program can be instantiated using different ports so be sure the camera you are interested in controlling is actually connected to the physical port.

Is the Tau 640 camera power on?

Verify that the camera is producing an image on a separate monitor. On cameras with a shutter installed, at camera power up, you can hear two sets of a click-click sound, separated by about 5 seconds, as the shutter performs its on-power-up calibration.

If you cannot initiate serial communication with the camera after verifying these items, refer to the frequently asked questions (FAQ) at www.flir.com/cvs/cores/faqs/tau/all/ or contact FLIR Customer Support at (805) 964-9797.



3.6 Operation of the FLIR Camera Controller GUI

When the FLIR Camera Controller GUI successfully links to the camera, you will see the window shown below. At the bottom of the application window, you should see Camera and FPA status.

The GUI provides five tabs allowing for camera control as described below.

Figure 3-2: FLIR Camera Controller GUI Status Tab

Camera Part #:

indicates the specific camera configuration connected.

Camera Serial #:

This is the serial number of the camera currently connected to the FLIR

Camera Controller GUI.

FPA Temperature:

The camera’s Focal Plane Array (FPA) temperature.

The connection status, Camera status, Camera Part #, FPA Temp, and FPA Size are displayed at the bottom of all tabs.



3.7 Setup Tab

The Setup tab, shown below, provides the ability to do the following:

Modify the Flat Field Correction (FFC)

Set the External Sync mode

Freeze the video via the Operating Mode section

Populate the Scratch Pad with text

Set the camera to generate a Test Pattern

Save the settings to the camera’s non volatile memory

Restore the Factory Defaults

Reset the Camera

Figure 3-3: FLIR Camera Controller GUI Setup Tab



Flat-Field-Correction Mode:

Tau 640 includes internal mechanisms for periodically improving image quality via a process called flat-field correction (FFC). During FFC, a shutter briefly blocks the detector array, presenting a uniform temperature (a flat field) to every detector element. While imaging the flat field, the camera updates correction coefficients, resulting in a more uniform array output. The analog video image is frozen during the entire process, which takes less than a half second, and resumes automatically thereafter. Repeating the FFC operation often prevents the imagery from appearing “grainy”. This is especially important when the camera temperature is fluctuating, such as immediately after turn-on or when ambient temperature is drifting. FFC can be controlled manually at any time using the Do FFC command button.

Tau 640 provides three FFC modes:

Auto

: In the Automatic FFC mode, the camera performs FFC whenever its temperature changes by a specified amount or at the end of a specified period of time

(whichever comes first). When this mode is selected, input windows are available in the FLIR Camera Controller GUI for specifying the temperature change and the number of frames that trigger automatic FFC. The temperature change is specified in degrees, with valid values in the range 0 to 100 in 0.1 degree increments. The time period is specified in analog video frames (33ms NTSC, 40ms PAL), with valid values in the range 0 to 30,000 frames. The second set of Auto FCC parameters labeled

Low Gain

apply to Tau 640-P cameras with the auto gain switch enabled.

Note

FLIR recommends using the factory default values for the two automatic-FFC parameters if possible. These values were selected to maintain a high degree of image quality over all camera operating conditions.

Manual

: In Manual FFC mode, the camera does not perform FFC automatically based on specified values of temperature change or expired time. The FFC will be performed once upon startup then again using the internal shutter whenever the Do FFC button is clicked. At camera temperature excursions beyond 0°C and 40 °C, a Do FFC command is recommended in order to maintain image quality.

External:

In External FFC mode a uniform source (blackbody) must be placed in front of the camera. The image of this uniform source will be subtracted from all subsequent images. This feature is useful if there are lens or lens mount nonuniformities that are not corrected by an internal FFC. The camera will not perform an

FFC process on startup if the saved state of the camera is External mode FFC.

Many customers have found that the palm of their hand or a table is an adequate uniform source to perform an External FCC.



The Tau 640 camera displays an onscreen symbol called the Flat Field

Imminent Symbol prior to performing an automatic FFC operation. As shown in

Figure 3-4, it is the square in the upper

right of the video output and is displayed nominally 2 seconds prior to the FFC operation. The duration of the FFC

Imminent Symbol can be set using the

FFC Warn Time

setting in the Analog

Video

tab. Setting the Warn Time to less than 15 turns off the warning (see

paragraph 3.8).

Figure 3-4: Flat Field Imminent Symbol

External Sync Mode:

The Tau

640 camera provides the ability to either accept or output a frame synchronization signal on pin 21 of the 50-pin

Hirose connector or pin 26 of the Photon Replicator board. This functionality can also be disabled. The designed signal levels are 0V and 3.3V.

Disabled

: The camera will turn off frame synchronization.

Slave

: The camera will accept a frame synchronization signal on the interface connector. The camera output will be frozen if the camera is in slave mode and no external synchronization signal is received.

The focal plane array readout cycle starts when the external synchronization signal is received and the camera will continue the output cycle until the frame is complete.

The frame sync signal embedded in the respective digital output should be used to acquire digital data, not the external sync I/O.

Maximum external sync input rates are up to 29.980 Hz for NTSC and 27.25 Hz for

PAL. The ‘Slow Video’ versions of the Tau 640 camera will have the same external sync frame rates, but the image data output will be at 1/4 the rate (NTSC) or 1/3 the rate (PAL).

Master

: The camera will output a frame synchronization signal on the interface connector when configured as a master. The output pulse width will be 100 ns at the standard frame rates (27.970 Hz for NTSC; 25.000 for PAL).

Operating Mode:

The Tau 640 camera will freeze the analog frame imaged when Frozen is selected. Live video will cease and the frozen frame will persist. To return the camera to live video, select Real-Time video mode.

Save Settings:

After using the FLIR Camera Controller GUI to change camera modes and settings to your desired values, use the Save Settings button to store your current selections as new power-up defaults. The next time the camera is powered, the Tau 640 camera will remember these saved settings. If you do not click Save Settings, the changes you make via the FLIR Camera

Controller GUI will be valid only for the current session. Cycling power to the camera will revert to the previously saved settings.



Factory Defaults:

The Factory Defaults button restores the camera’s settings to the initial values specified by the manufacturer.

If you want the factory default settings to become the power up defaults, first click the Factory Defaults button, then click the Save Settings button.

Reset Camera:

The Reset Camera button restarts the camera software.

Test-Pattern:

A Test-Pattern mode is provided to verify camera electronics. The Test-Pattern mode will not persist over a power cycle.

Off

: No test-pattern is provided in this mode.

This is the normal mode for viewing thermal imagery.

Ramp

: In this ramp mode, the test pattern shown below and in the Color/LUT section that follows is provided at the analog and digital data channels.

pix(0,0) = 0 pix(639,0) = 639 pix(383,25) = 16383 pix(384,25) = 0

Figure 3-5: Ramp test pattern example for Top Portion of Tau 640 Ramp Image

(Digital values shown apply to the optional 14-bit digital data stream.)

The above ramp pattern repeats 19 times in the complete 640 × 512 image.

Note

The ramp test pattern is intended primarily for verifying the output of the digital data channel.

The pattern will not necessarily look as shown above when displayed on an analog video monitor, particularly if an Automatic Gain Control (AGC) mode other than Automatic is selected. The above image is a horizontal slice of the full displayed image.



3.8 Analog Video Tab

The Analog Video tab on the FLIR Camera Controller GUI, shown below, provides the ability to modify Tau 640 camera modes:

Image Orientation

Pan & Zoom

Polarity/LUT (Video Color)

FFC Warn Time

Dynamic Digital Detail Enhancement (DDE)

Video On/Off

Video Standard NTSC/PAL

1. Select Video

2. Select Analog Video

Figure 3-6: FLIR Camera Controller GUI Analog Video Tab



Image-Orientation Mode:

Two Image-Orientation mode selections are provided. Select one or both to change the orientation of the video image.

Invert

: The normal image is flipped vertically. The pixel on the upper-left corner of the detector array is displayed on the lower-left corner of the video display in Invert mode. Invert is used when mounting the camera upside-down. Invert applies to analog, BT.656, CMOS, and LVDS video.

Revert

: The normal image is flipped horizontally. The pixel on the upper-right corner of the detector array is displayed on the upper-left corner of the video display. Revert mode produces a mirror-image of Normal mode; use for applications where the camera is imaged through a mirror. Revert applies to analog and BT.656 video only.

Note

Any time the image orientation mode is inverted, a flat-field correction automatically takes place. Adjusting image orientation should always be followed by a flat-field correction in all modes.

Pan & Zoom, Zoom:

The Tau 640 camera has a built-in 2×, 4×, and 8× digital

Select to enter offsets

zoom capability. The Zoom check boxes are used to turn on/off the camera zoom. With the Unzoom box checked, the Tau 640 camera displays the full sensor array image.

When the Zoom 2x box is checked, a smaller central region of the sensor array is mapped to the video output creating the zoom effect.

For NTSC and PAL video formats in 2× zoom mode, 320 × 240 and 320 × 256 pixels, respectively, are mapped to the analog video output. When the Zoom 4x box is checked,

160 × 120 (NTSC) and 160 × 128 (PAL) pixels, respectively, are mapped to the analog video output. When the Zoom 8x box is checked, 80 × 60 (NTSC) and 80 × 64

(PAL) pixels, respectively, are mapped to the analog video output. This reduced region of the array is called the zoomed array region.

The BT.656 video output also has the zoom feature, but the CMOS and LVDS do not.

Click to center

Tilt slider

Pan slider

Pan & Zoom, Pan:

When in either zoomed mode, you can move the zoomed array region within the full array area. This digitally simulates panning and tilting. Panning and tilting are defined as moving the camera image in the horizontal and vertical axes, respectively. The FLIR

Camera Controller GUI Pan and Tilt limits are ±80 × ±60; and ±40 × ±30 when in the Fine range.

Checking the fine box increases the sensitivity of the slide control so that the zoomed array moves one half the total range but all step values are achievable. Simple experimentation while viewing the displayed image will quickly give you familiarity with this feature.



Flat-Field Correction (FFC):

The Tau 640

automatically performs flat-field corrections (see paragraph

“Flat-Field-Correction Mode:” on page 3-12). A green square

is displayed on your video monitor as a warning that the FFC is going to take place. Use this function to set the number of analog video frames (33ms NTSC, 40ms PAL) during which the warning will be displayed. The time period, specified in frames, can range from 0 to 30,000 frames. The factory setting of 60 frames equates to a two second warning. Setting the FFC Warning to less than

15 turns off the warning.

Dynamic Digital Detail Enhancement (DDE) filter:

The DDE algorithm sets edge enhancement dynamically proportional to the number of bins occupied in the image histogram.

In a high dynamic range scene the gain will be higher than in a low dynamic range scene. This allows faint details to be visible in high dynamic range scenes without increasing temporal and fixed pattern noise in low dynamic range scenes.

The DDE filter operates independently from the AGC and will enhance edges without effecting brightness or contrast. The valid range of Dynamic DDE setting is from 1 to 63 with 17 being the neutral setting where the filter has no effect. Settings below 17 will smooth the image reducing the appearance of sharp edges. Higher DDE settings will enhance all image nonuniformities resulting in a very detailed but grainy picture especially in high dynamic range scenes. Typical factory settings are between 25 and 30. Settings from 18 to 39 are normal imaging modes where the edge enhancement can be tuned for the scene. Use the slider to adjust the setting, or select the text field and type in the desired setting. Avoid using setting 16.

Note

In 14-bit Raw mode, selecting the DDE mode will not affect the digital data output.

Video On/Off:

This feature allows you to turn off the analog video output which will result in some power savings (approximately 55mW).

Video Standard:

Choose the video standard for your system.



Polarity/LUT:

The Tau 640 camera detects and images the temperatures in a given scene. Within the camera, these temperatures are mapped (as determined by the AGC algorithm selected) to a range of

0 to 255 values. In a black and white display mode, this range is converted to shades of grey with, for example, 0 being totally black and

255 being totally white. The 0 to 255 grayshades range sensed is referenced to a Look-Up Table (LUT) permanently stored in the camera to convert the scene to a video image. Different LUTs are available to change the appearance of the displayed image. The most common selection is either White Hot (hotter objects appear brighter than cooler objects in the video display) or Black Hot (hotter objects appear darker than cooler objects). Since the difference between these two modes simply reverses the choice of darker or lighter for temperature extremes, this is sometimes referred to as Polarity. Other color LUTs are available as shown below.

Figure 3-7 shows each of the LUTs as displayed in Test Pattern Ramp Mode starting with the upper left: White Hot, Black Hot, Fusion, Rainbow, Globow, Ironbow1, Ironbow2, Sepia, Color1,

Color2, Ice Fire, Rain, Red Hot, and Green Hot. Select one of these LUTs from the pull-down menu to view your image displayed using the LUT you choose. The setting of the Polarity/LUT mode will not affect the digital data output.

3.9 Digital Video Tab

Tau 640 offers a LVDS interface digital output that can be configured in four modes. Changing these modes will have no effect on the analog (NTSC or PAL) signal. In order to access the

digital output, you must use an advanced interface as described in Chapter 4, Tau 640 Digital

Data Channel. See the Tau 640 Electrical Interface Control Document (102-PS220-41) for

information on how to access digital video for LVDS, BT.656, and CMOS.

Camera Digital Output

Note

The Revert feature is not available in CMOS or LVDS digital data.

Note

AGC mode will only affect the digital data output if Camera Digital Output mode is set to 8-bit data.

Off

: The digital data stream coming from the Tau 640 camera is turned off.

8-bit

: Data from the 640 × 480 (NTSC) or 640 × 512 (PAL) video pixels is provided after application of the current Automatic Gain Control (AGC) and Dynamic Detail

Enhancement (DDE). The 8-bit data is essentially a digital version of the same data provided on the analog video channel.

14-bit Filtered

: Data from 640 × 512 pixels is provided prior to video processing modes in the 8-bit data described above. The 14-bit data is the filtered data to include the Dynamic Detail Enhancement (DDE) and will appear gray when saving 16-bit TIFF

files. See “Tau 640 Digital Data Channel” on page 4-1.

14-bit Raw

: Data from 640 × 512 pixels is provided prior to all video processing and does not include the Dynamic Detail Enhancement (DDE) or bad pixel replacement.

The 14-bit data is the ‘raw’ data and will also appear gray when saving 16-bit TIFF

files. See “Tau 640 Digital Data Channel” on page 4-1.

XP Mode Select

The Tau 640 camera has 18 XP pins on the 50-pin Hirose connector. The XP mode uses a number of these pins to output parallel digital image data.

BT656

: The BT.656 parallel output is a common interface which will drive many LCD displays. The data is digitally encoded NTSC/PAL video and will have AGC, DDE, symbols, and color included.

CMOS

: The CMOS interface is a parallel output that allows the user to access 8-bit

AGC corrected data or 14-bit data. The signal levels are 0 - 3.3 V CMOS logic and are intended to drive boards mounted directly to the Tau 640 camera. CMOS is not intended to drive a cable. An XP-board (1.5” by 1.5”) reference design is available upon request.



3.10 Image Capture Tab

The Image Capture tab on the FLIR Camera Controller GUI, shown below, allows you to capture three 8-bit AGC corrected images to camera memory for retrieval to a host computer. The images will be 8-bit grayscale only, without symbols. (The camera actually captures and stores14-bit images and the FLIR Camera Controller GUI displays them as 8-bit images with linear AGC applied.) The Tau 640 camera allows the user to save either 8-bit or 14 bit images.

To save an 8-bit images in a .bmp format, click the Save Currently Displayed Image button. to save a 14-Bit image right clicking in the image and select save.

3.11 AGC Tab

The AGC tab, shown in Figure 3-10, controls the Automatic Gain Control (AGC) mode or

algorithm along with selectable parameters. Only one mode can operate at a time and is selected by clicking one of the Algorithm buttons in the upper left portion of the window.

Parameters for a given mode are contextually made available depending on which mode is selected. The Region of Interest (ROI) for the AGC mode is adjustable as well (see

paragraph 3.12).

1. Select AGC tab

2. Select AGC

Figure 3-10: FLIR Camera Controller GUI AGC Tab

Note

FLIR has invested heavily in designing high quality AGC algorithms. The default mode

(Automatic) along with the default parameter settings for the Automatic AGC mode have been proven to offer the best image quality for generalized scene imaging. Also, be aware that you can make AGC adjustments that will configure the Tau 640 camera to produce no image (all

black or all white). Restoring the Factory Defaults on the Setup Tab will return the camera to

its factory default state and likely restore normal camera operation.



AGC Modes:

The Tau 640 provides five AGC algorithms for Image-Optimization:

Automatic

: This is the most sophisticated algorithm and for most imaging situations, the best all-around choice. This factory default along with the default parameter settings should be used in general imaging situations. In Automatic, image contrast and brightness are optimized automatically as the scene varies. This mode provides an AGC which is based on a histogram-equalization algorithm. Controls for the

ITT Mean

(gray scale mid-point), Max Gain (AGC gain) and Plateau Value are enabled.

The histogram equalization used in the automatic mode scales the 14-bit to 8-bit transfer function based on the number of pixels in a bin. The more pixels in a bin, the higher the gain. But the Plateau value is the pixels/bin limit when the transfer function is maximized. Normally 250 is the plateau value for imaging cameras when more contrast is desired.

This algorithm analyzes the scene content in real time and redistributes the dynamic range of the scene. The goal of this redistribution is that every one of the 255 bins of display dynamic range has an equal number of pixels in it. This method tends to give better scene contrast under conditions where the scene statistics are bimodal (for example, a hot object imaged in a cold background. It should be noted that the heat range in a given scene is not divided evenly across the grey levels sent to be displayed.

Instead, the AGC algorithm analyzes the scene and distributes the dynamic range to best preserve statistical scene content (populated regions of the histogram) and display a redistributed scene representation.

Once Bright

: In this mode, the brightness will be set once when the mode is selected.

The brightness (level) is calculated as the mean of the current scene when the Once

Bright

button is selected. The scene is mapped to the analog video using a linear transfer function. Image contrast can be adjusted by the Contrast slider. This is the only user adjustable parameter. Upon entry into the once bright mode, the currentlystored value of contrast is applied (i.e. the power-on defaults or the last saved values).

Auto-Bright

: In this mode, the brightness (level) is calculated as the mean of the current scene just as in Once Bright mode. The difference with Auto-Bright is that the values selected for the start and end of the linear transfer function are automatically updated in real-time, not only at the start of AGC mode selection. The

Brightness Bias

offsets the displayed image in intensity. Upon entry into the auto bright mode, the currently-stored values of Contrast and Brightness Bias are applied

(i.e. the power-on defaults or the last saved values).

Manual

: In this mode, image Contrast (gain) and Brightness (level) are entered completely manually via the sliders. The scene is mapped using a linear transfer function. Upon entry into the manual mode, currently-stored values of brightness and contrast are applied (i.e. the power-on defaults or the last saved values).



Linear Histogram

: Image contrast and brightness (gain and level) optimized automatically based upon scene statistics using a linear transfer function. Controls for the ITT Mean (sets grey scale midpoint) and Max Gain (AGC gain) are adjustable by entering the value in the Automatic Parameters section. The Linear Histogram algorithm uses scene statistics to set a global gain and offset (contrast and brightness) for the image. Upon entry into the linear histogram mode, the currentlystored values are applied (i.e. the power-on defaults or the last saved values).

Note

In Manual mode and Once Bright mode, the brightness setting must be updated as the

camera temperature changes. To avoid this issue, it is recommended to use Automatic or

Auto Bright

right modes when possible. Also, AGC mode will only affect the digital data output if the Digital Video output mode is set to 8-bit data. The 14-bit digital data bypasses the AGC sections of digital processing.

Linear Parameters:

Used for fine tuning the Auto Bright, Once

Bright

, and Manual modes, these settings are contextually active depending on which Algorithm is selected. Each of their settings is described above.

Once Bright

– Only the Contrast control is active.

Auto Bright

– The Brightness Bias and Contrast controls are active.

Manual

– The Brightness and Contrast controls are active.

Automatic Parameters:

Used for fine tuning the

Automatic

and Linear Histogram modes, these settings are contextually active depending on which AGC algorithm is selected. Each of their settings is described above as they pertain to the particular Algorithm.

Automatic

– The Plateau Value, ITT Mean, and Max

Gain

controls are active.

Manual

– The ITT Mean and Max Gain controls are active.



3.12 ROI Tab

The Tau 640 camera allows the user to set a Region of Interest (ROI) or a rectangle of pixels on the sensor array that the AGC algorithm will use for its calculations. The ROI can be set for either the entire frame size (0,0 : 640,512) or some smaller portion as shown below. The ROI

tab, shown in Figure 3-11, provides both a Window Editor and text entry coordinates to control

the size and location of the Region of Interest (ROI).

1. Select AGC tab

2. Select ROI Window editor

Figure 3-11: FLIR Camera Controller GUI ROI Tab



Window Editor:

Use the mouse to drag the green ROI rectangle to any location on the FPA. The size of the ROI rectangle (in pixels) is displayed. To change the size of the ROI rectangle, drag one of the corner or side bubbles.


AGC ROI Coordinate Values:

The settings use an X-Y coordinate system with (0,0) being at the center of the sensor array. The upper two numbers marked (left,top) are the pixel coordinates of the upper left corner of the ROI rectangle. The lower two numbers marked (right,bottom) define the lower right corner of the ROI rectangle. In the example at the right, the ROI is specified as a ROI rectangle 66 × 65 pixels located 20 pixels to the left and 10 pixels down from the center of the FPA.

The new AGC ROI size setting is not active until the Set button is pressed.

The AGC ROI may be set independently for Unzoom,

Zoom 2×

, Zoom 4×, and Zoom 8×. The AGC ROI may be set anywhere in the full array size, even outside the zoom window. The Pan and Tilt function will attempt to move the Zoom AGC ROI to remain centered on the zoom window. If the camera is being used in zoom mode, it is recommended that the zoom AGC ROI be set to the same size as the zoom window.


4 Tau 640 Digital Data Channel

The Tau 640 camera provides three digital data channels which can be configured through

software from the generic pinout definitions shown in Table 5-2 on page 5-2. The BT.656

channel output is a digitally encoded analog format which contains image, symbol, and color information. The CMOS channel is a parallel image data output. The Legacy LVDS channel is common with the FLIR Photon camera. Designers and integrators should provide electrostatic discharge (ESD) and over voltage protection for Tau 640 cameras using digital data channels because the digital signals on the 50-pin Hirose connector are routed directly to the FPGA.

4.1 XP Bus Setting—BT.656 Digital Interface

The BT.656 parallel output is a common interface which will drive many LCD displays. The data is digitally encoded NTSC/PAL video and will have AGC, DDE, symbols, and color included. The signal levels are 0 - 3.3 V CMOS logic and are intended to drive boards mounted directly to the

Tau 640 camera. The BT.656 output is not intended to drive a cable. Table 4-1 shows the connector pin definitions with BT.656 enabled. Also shown in the table are the optional discrete

input pins. Figure 4-1 details BT.656 format and timing. The horizontal pixels are interpolated

such that every eighth pixel is replicated (640 x 9/8 = 720) to produce the 720 pixels per line required by the format.

4.2 Discrete I/O

By default the Tau 640 camera does not have discrete input functions loaded. The eight discrete input/output pins with functions are defined by the discrete control file which is available for download and installation. These functions can be used with the BT.656 digital output but are not intended to be compatible with Tau 640 camera using CMOS output. The discrete control file is defined in Table 4-2.

Note 1 This function is a backward compatible function with Photon. The voltage level of this pin controls the LUT applied to the analog image. The pin has a pull-up so that the no-connection state is High (3.3 V). When this pin is high (3.3 V), the analog image will use the White Hot pallet (LUT 1 in the standard LUT file). When this pin is low (0 V), the analog image will use the Black Hot pallet (LUT 2 in the standard LUT file). The camera will power up in the saved default state and switch to the discrete input defined state when the pin state is changed.

Note 2 This function is a backward compatible function with Photon. The voltage level of this pin controls the zoom state of the analog image. The pin has a pull-up so that the no-connection state is High (3.3 V). When this pin is high (3.3 V) the analog image will be in the 1x zoom state. When this pin is low (0 V) the analog image will be in the 2x zoom state. The camera will power up in the saved default state and switch to the discrete input defined state when the pin state is changed.

Note 3 This function is required for effective use of Shutterless Tau 640 cameras. The application of positive going edge to this pin shall perform the Do FFC function (0x12 command).

Note 4 This pin is normally at 0 V and changes to 3.3 V when the FFC imminent icon is present on the analog display.

The FFC_Warn_Time command (0x3C) controls both the analog icon and this pin.

Note 5 This function is required to enable additional user control of the camera. The default state is Automatic mode with the input at 3.3 V held by an internal pull-up. When the signal is pulled to zero volts the camera will switch into Manual mode. The FFC_Mode_Select (0x11 0=manual, 1=automatic) command has equal precedence with the discrete pin and the camera will be in the last state set by either the discrete or serial command. The camera will power up in the saved default state and switch to the discrete input defined state when the pin state is changed.

Note 6 This function will change the color LUT from the current value to the next LUT in the table when the Discrete pin transitions from the floating state to the ground state. No LUT change happens on the transition from ground to float. The LUT state after LUT14 will be LUT1.

Note 7 This function will change the current zoom state from Unzoomed to 2x to 4x to 8x zoom whenever the discrete pin changes from the float state to the ground state. The Video_Mode command (0x0F) has equal precedence with this command.

Note 8 Not defined. Connection of either 3.3 V or 0 V to this pin will have no effect on camera operation.



4.3 XP Bus Setting—CMOS Digital Interface

The CMOS interface is a parallel output that allows the user to access 8-bit AGC corrected data or 14-bit data. The signal levels are 0 - 3.3 V CMOS logic and are intended to drive XP-boards mounted directly to the Tau 640 camera. CMOS is not intended to drive a cable. An XP-board reference design is available upon request.

Table 4-3 shows the connector pin definitions with CMOS enabled.

Note

The optional discrete input pins should be unloaded when using the CMOS output.

4.4 Camera Link Interface

The Tau Camera Link accessory board can be used to capture digital data from the Tau camera. The Tau Camera Link accessory board has four connectors.

• The Camera Link accessory board has the mate to the 80-pin Hirose connector on the Tau core. Power and communication are supplied to the core from the Camera

Link accessory. The core receives analog video and CMOS digital data from the core.

• The mini-USB connector receives power and communication from a host though the

USB cable. The Camera Link accessory converts USB protocol to high speed serial format for the Tau core.

• The MCX coaxial connection provides access to the camera analog video output

(NTSC or PAL)

• The 26-position Mini-D-Ribbon (MDR) Camera link connector provides the output interface for camera digital data. This connector does not support power over

Camera link. This connector does not support serial communication over Camera

Link.

This accessory conforms to the Camera Link standard as Base Configuration type 14-bit x 1.

The Tau CMOS data interface has a Frame sync, Line sync, Data bus, and a pixel clock which runs at 10.5MHz (see section 4.X). To be compliant with the transmission standard the Tau

Camera Link accessory up samples data to achieve minimum data rate. The Camera link data clock is running at 21MHz. Data is double sampled so that the output is equivalent to: Pixel1,

Pixel1, Pixel2, Pixel2, Pixel3, Pixel3, …, Pixel638, Pixel 638, Pixel639, Pixel639 in each row.

The Frame Valid clock it true during valid lines of data. The Line valid clock is true during valid pixels in each line. The Data Valid clock is true for every other pixel. It is important that the

Camera Link receiver device uses all three control clocks (some inexpensive models ignore Data

Valid).

In order to use a Camera Link Module for acquisition of data, you will need to first enable the

CMOS XP Bus Output using the FLIR Camera Controller. This option is found under Video =>

Digital Video. On this same page, you can select either 8-bit or 14-bit digital output. Once you make these changes, it is a good idea to save settings to make them power cycle consistent.

You can do this after clicking Setup.

The digital data complies with Base Camera Link standards and should be compatible with any brand Camera Link Frame Grabber and software. FLIR has tested the ImperX FrameLink

Express frame grabber ( http://imperx.com/frame-grabbers/framelink-express ).

The FLIR Camera Controller allows for control of the Tau Camera, but does not support Camera

Link frame capture and third-party software must be used. The ImperX frame grabber comes

FrameLink Express software that allows for recording single or multiple images (BMP, JPG, TIF, and RAW) as well as standard AVI clips. Configuration requires selecting 1 TAP, L->R for the tap reconstruction, selecting the appropriate bit depth that you chose in the FLIR Camera

Controller, and clicking “Learn” to discover the number of digital pixels available.



4.5 Photon Camera Legacy LVDS Output

The Tau 640 camera provides a digital data channel that outputs camera data in a digital format compatible with FLIR Photon camera tools and accessories. This channel can be used in conjunction with commercially-available digital frame grabbers, digital displays, or custom electronics. For Tau 640 users with applications that require custom control software, a

Software Developer’s Kit (SDK) is available to support your development. The SDK accessory is described in the Accessories portion of this User’s Manual. Using the Digital Data Channel is an advanced regime that should only be attempted by qualified customers.

The digital data channel can be configured to output 14-bit data after application of calibration

(Non Uniformity Correction or NUC) terms. This mode is most useful for external signalprocessing and/or analysis of the camera output. The digital channel can also be configured to provide 8-bit data after application of video processing algorithms—Automatic AGC mode, white-hot/black-hot polarity, image orientation (Invert, but not Revert), and DDE filtered. The 8bit data is essentially a digital version of the video stream provided on the analog video channel and is therefore more appropriate than the 14-bit data for interfacing to a digital display.

The digital data channel employs serial low-voltage differential signaling (LVDS). The channel consists of three signal lines—a clock, a composite sync (frame sync and data valid), and serial data. This is a modern high speed interface employing a twisted pair current loop architecture.

National Semiconductor offers a good introduction and overview in the following document: http://www.national.com/appinfo/lvds/files/lvds_ch1.pdf

.

A serial-in-parallel-out (SIPO) module is available from FLIR for converting the serial data to 14bit parallel LVDS output (plus frame sync, line sync, and pixel clock). The parallel data can be captured using a frame-grabber board installed in a PC.

One frame grabber possibility is the National Instruments IMAQ PCI-1422 board using digital interface cable part number 308-0013-00. Another frame grabber option is the Bit Flow

RoadRunner Model 14-M board using digital interface cable part number 308-0016-00-03.

Both of these computer-based frame grabber boards require third-party software not offered or supported by FLIR.

FLIR supplies camera setup files for both the IMAQ and Bit Flow frame grabber boards, but

FLIR does not formally support their use, nor do we claim or guarantee that these setup files will be suitable for any particular use or application.

Refer to http://www.flir.com/cvs/cores/resources/software/ .



4.5.1 Using the Legacy LVDS Digital Data Channel

Note

The following instructions assume that you have purchased the optional Tau 640 Photon

Replicator Kit; and have the Photon Legacy serial-to-parallel-out (SIPO) accessory module with parallel data cable and the appropriate Photon Accessory Kit (including the I/O Module and cables shown below. If you are using custom cabling and/or interface electronics, contact

FLIR Customer Support at (805) 964-9797 if you need additional assistance.

Follow the steps in paragraph 3.1 “Operation of the Tau 640 Camera using the USB Interface” on page 3-1 for basic operation of the Tau 640 camera. After verifying that the camera is

operating properly, disconnect power from the Tau 640 camera.

Step 1 Connect the SIPO accessory module directly to the three-row DB-15 connector on the

Interface Module labeled DIGITAL DATA as shown below. A cable is NOT required.

I/O Module

To Photon

Replicator Board

SIPO Module

To frame grabber board

Step 2 Connect the parallel data cable to the mating connector on the SIPO module. Connect the other end to the frame-grabber board installed in your PC.

Note

The parallel data cable is specific to a particular frame grabber. Contact the manufacturer of the frame grabber to make sure you have the correct cable.

Step 3 Follow instructions included with the frame grabber for selecting the camera configuration file included with the SIPO module.

Step 4 Reapply power to the Interface Module. This will power-up both the Tau 640 camera and the SIPO module, and digital data will begin streaming.

Step 5 If desired, change the digital data mode using the FLIR Camera Controller GUI software in the Digital Video tab.



4.5.2 Legacy LVDS Digital Data Channels

The camera provides two digital ports.

• Port 1 consists of the signals SD_CLK+, SD_FSYNC+, and SD_DATA1+, SD_DATA2.

• Port 2 consists of the signals LVDS_VID1+, and LVDS_VID2+.

Note

14-bit and 8-bit timing and format are identical except only 8 bits (LSBs) are available in 8-bit mode.

Port 2 is currently undefined—do not connect to these signals

All signals in the digital data interface employ low-voltage differential signaling (LVDS).

The clock rate of DATA_CLK+ is 73.636 MHz.

The timing of the digital data interface is shown in Figure 4-4 and Figure 4-6.

Note

The LVDS Data_Out transitions on the rising edge of DATA_CLK+ and there is no delay.

Data should be sampled on the falling edge of DATA_CLK+.

The format of the digital output shall be is in Figure 4-5.

5 Overview of the Electrical Interface

5.1 Input Power

The Tau 640 camera operates from DC power per the specifications given below. It is common in simple operational scenarios to use an inexpensive wall-powered adapter. The Tau VPC module makes this easy by providing a USB connection.

The camera operating in a steady-state condition consumes around 1W of power. During startup there is an inrush current of up to 1 A (at 5 V) for 1 ms. Cameras equipped with the compact shutter will draw 2.75 W (550 mA at 5 V) for 200 ms during the flat-field operation which occurs during startup and periodically thereafter. Typical start-up times are 3 to 4 seconds.

Caution!

Reversing the polarity of the input power will damage the camera’s internal power supply.

This damage will not be covered under the camera warranty.

The Tau 640 camera has been tested and found to meet radiated emissions specifications of

FCC CFR Title 47 Part 15 Subpart B, and EN 61000-6-3 (CISPR-22 limits equivalent to Class

B) when properly shielded and grounded. The less stringent Class A requirements are met with the back cover on. It is the responsibility of the systems integrator to verify EMI/EMC compliance at the system level.

5.2 Hirose 50-Pin Connector

In the Tau 640 camera’s simplest form (no accessories attached), one connector provides the electrical interface. This connector is a 50-pin Hirose board-to-board style connector, per

Hirose Part Number: DF12-50DS-0.5V(86). Hirose offers a variety of mating connectors including their SFM(L), SMT, and SFSD style products. Designers and integrators should provide electrostatic discharge (ESD) and over voltage protection for Tau 640 cameras using digital data channels because the digital signals on the 50-pin Hirose connector are routed

directly to the FPGA. The primary Tau 640 connector is shown in Figure 5-1.

Tau 640 User’s Manual 5—Overview of the Electrical Interface

5.3 Analog Video Output

The Tau 640 camera can be configured to provide either NTSC or PAL analog video output.

These analog output standards allow direct video connection to common video display or recording devices such as TV monitors and VCRs. Typically, an analog monitor input signal is provided over a coaxial cable and uses either an RCA (consumer based electronics) or BNC

(generally associated with professional or scientific equipment) style connector.

When the VIDEO_LO signal is tied to ground, the analog video signal meets the timing and voltage requirements of either NTSC or PAL protocol. (The FLIR Camera Controller GUI software allows you to select between NTSC or PAL video output formats. The NTSC analog video format is the default in all cameras.)

If you are creating a custom cable to carry the analog video signal from the Tau 640 camera to your monitoring or recording device, you should use 75 Ohm characteristic impedance coaxial cable and terminate into a 75 Ohm monitor. These specifications represent standard video cabling and I/O and will likely be the default for any generic video receiving hardware you purchase. Per the pin function table, you will use the VIDEO_LO and VIDEO_HI pins for the analog video output signal. Specific video characteristics are given in the table below.

5.4 Command and Control Channel

Remote control of the Tau 640 camera is provided via a RS-232 serial interface consisting of

signals named RX, TX and GND using 3.3 volt signal levels. Chapter 3 provides information

regarding remote control using the FLIR Camera Controller GUI. Appendix B describes the

serial communications protocol in detail for the Tau 640 camera.

5.5 LVDS Digital Data Channel

The Tau 640 camera provides real-time serialized digital video. The camera outputs either 8-bit or 14-bit data using the SD_CLK±, SD_FSYNC± and SD_DATA± signals. Conversion of the serial data to a parallel format for data acquisition requires a serial-to-parallel converter accessory.

Information regarding the digital data interface is provided in Chapter 4.

5.6 Parallel Digital Data Channel

The Tau 640 camera provides a digital parallel channel with real-time parallel digital video. The

XP-Bus may be configured for either CMOS or BT.656 format. Information regarding the digital

data interface is provided in Chapter 4.

Appendix B Serial Communication Technical Details

B.1 Serial Communications Primary Interface

The camera is capable of being controlled remotely through an asynchronous serial interface consisting of the signals named RX, TX, and GND using 3.3 volt signal levels.

Note

The camera is compatible with most RS232 drivers/receivers but does not implement signaling levels compliant with the RS232 standard voltage levels.

B.2 Serial Communications Protocol

• The required serial port settings are shown in Table B-1.

• The camera does not generate an outgoing message except in reply to an incoming message.

• The camera generates an outgoing reply to each incoming message.

• All messages, both incoming and outgoing, adhere to the packet protocol defined in

Table B-2 and the subparagraphs that follow. The first byte i.e., the Process byte is

transmitted first followed by the rest of the bytes in the order specified.

• All multi-byte arguments defined herein uses big-endian ordering (MSB first).

• The serial inter-byte timeout is factory set to 100ms

• Only use the function commands listed in Table B-4. Unsupported commands may corrupt the camera's software.

• For reference only, a sample command and response is shown in Table B-5.

Example Process Code

Transmission is LSB first (for each byte) and most significant byte first on multi-byte messages. All bytes are preceded by a zero start bit and followed by a one stop bit.

The camera core is designed to talk to a PC serial port directly and may seem inverted if direct communication to a logic device is desired.

6E = 0 0111 0110 1 = Start bit, E with LSB first, 6 with LSB first, Stop bit

On an oscilloscope the observation is, Idle low but, zero high. Starting at idle, when the signal goes high, that is the first 0; then two 0’s high, three 1’s low, one 0 high, two 1’s low, one 0 high, one 1 low, (6E complete).

B.4 Function Byte

The list of valid commands that can be set in the Function Byte is shown in Table B-4.

For all reply messages, the camera will echo back the Function Byte of the previous incoming message.

For all commands in which the byte count is listed in Table B-4 as either 0 or some non-zero value, the camera will change the value of the specified parameter according to the incoming data bytes if there are any (i.e., the camera shall set the parameter) or it will reply with the current value of the parameter if the incoming message contains no data bytes (i.e., the camera shall get the parameter).

B.4.1 Byte Count Bytes

• On all incoming and outgoing messages, the Byte-Count Bytes are used to specify the total number of data bytes in the packet.

Note

The number of data bytes in the packet is not equal to the total number of bytes in the packet. For example, a No-Op serial command contains zero data bytes.)

• The Byte Count must be an even number from 0 to 0x1F4 (500 decimal).

B.4.2 CRC Bytes

• On all incoming and outgoing messages, two cyclical redundancy checks (CRCs) are calculated using CCITT-16 initialized to 0.

• CRC1 is calculated using only the first 6 bytes of the packet.

• CRC2 is calculated using all previous bytes in the packet (i.e. bytes 0 through N).

B.5 Example of the format of a serial message

Table B-5 describes the bytes that are transferred when the FFC_MODE_SELECT (0x0B)

command is issued to the camera to set the mode to Auto (0x01) and to get the FFC mode:

B.6 Description of Serial Commands

B.6.1 Camera Defaults

The RESET_FACTORY_DEFAULTS command sets the current settings to the factory default values. In order to save these values as power up defaults, it is necessary to do a

SET_DEFAULTS command.

B.6.2 AGC algorithms

Use the AGC_TYPE command to select one of the following AGC algorithms:

• Automatic

• Once Bright

• Auto Bright

• Manual

• Linear

B.6.3 Pan and Tilt

The PAN_AND_TILT command controls this feature in the camera when the image is zoomed. It does not have any effect when the image is not zoomed. The center of the screen is considered as coordinate (0,0).

A positive number is needed to pan right and negative number to pan left. A pan value of 1 pans to the right by one column and a pan value of -1 pans to the left by one column from the center of the image.

A positive number is needed to tilt downwards and a negative number to tilt upwards. A tilt value of 1 tilts downwards by one row and a tilt value of -1 tilts upwards by one row from the center of the image.

When the image is being panned or tilted the ROI moves along with these coordinates. The limits for the zoom ROI have been set to one and a half times the number of rows and columns in the video. This is to enable a user to pan and tilt the zoomed portion of the image without any change in the AGC if the image being looked at does not change. This also means that the AGC of the image is also determined by portions of the image that is not being currently viewed.

B.6.4 DDE filter

The commands to control the DDE filter settings are DDE_GAIN to control the gain,

DDE_THRESHOLD to control the DDE filter threshold, and SPATIAL_THRESHOLD to control the spatial threshold of the DDE filter. The image remains unchanged when the value of the DDE gain is 0 and 17. The image becomes unfocused/unsharpened when the value is between 1 and 15. The image becomes more sharpened when the value is above 17. Increasing the DDE threshold will make the edges sharper. For threshold values between 0 and about 50 the effect on the image is lesser and has a greater effect above approximately 50. Increasing the spatial threshold value will make the image look smoother.



The DDE filter has an automatic mode that when activated controls the DDE Gain using a combination of the Dynamic DDE setting and the scene dynamic range. The valid range of the

Dynamic DDE setting is from 1 to 63. Dynamic DDE settings between 1 and 16, provide image smoothing, with a setting of 1 providing the most smoothing. A Dynamic DDE setting of 17 turns off the Dynamic DDE. A Dynamic DDE setting between 18 and 39 sets the imaging mode

DDE Gain between 16 and 40. A Dynamic DDE setting of 40 or greater provides maximum enhancement but image artifacts may also be enhanced giving an image with some fixed pattern noise.

The camera provides a spare serial communications port consisting of the signals: RX2, TX2, and GND.

Note

This serial communications channel is intended for communication with RS-232 controllable systems.

B.6.6 Digital data

The DIGITAL_OUTPUT_MODE command allows the users to select one of the following digital data options

• 14-bit data

• 8-bit data

• digital off

• 14-bit unfiltered

• 8-bit inverted

• 14-bit inverted

• 14- bit inverted unfiltered

• XP-channel setting




Appendix C Tau 640 with Photon Accessories

C.1 Operation of the Tau 640 camera using the Photon Accessory Kit

Backward compatibility with existing Photon equipment allows Photon users to connect to the

Tau 640 camera to provide power and obtain video. It also facilitates serial communication for more advanced camera command and control via the free downloadable FLIR Camera

Controller GUI. In this first section, we will discuss simply applying power and obtaining video.

Using the Accessory Kit’s Interface Cable and I/O Module, plug one end of the Interface Cable into the mating connector of the Photon Replicator Board on the back of the camera. Connect the other end of the Interface Cable to the mating connector on the I/O Module labeled

CAMERA

.

I/O Module

To video monitor

To Photon


To power supply

(206-0001-20)

Attach one end of a standard BNC cable to the video port labeled VIDEO on the I/O Module.

Attach the other end to a compatible video monitor’s composite video input. If your monitor has an RCA input connector, a BNC to RCA adapter can be used.

Plug the power supply into an electrical outlet. Insert the circular plug at the other end of the power supply into the power jack labeled POWER on the I/O Module and tighten the locking screw finger tight. The camera will take ~3 seconds to produce an image after you apply power.

You should see an initial splash screen with the FLIR logo displayed, and then live long-wave infrared video will follow! Point the camera in different directions and notice the imagery. If the video image appears low in contrast, point the camera at a target with high thermal contrast such as at a person.

Appendix C—Tau 640 with Photon Accessories Tau 640 User’s Manual

C.2 Remote control of the Tau 640 camera

The Tau 640 camera accommodates advanced camera control through an RS-232 serial interface. A user can control the camera through this interface using their own software and hardware by following the Serial Communication Protocol and command structure defined in

Appendix B. This requires programming skills and a strong technical background. The user can

also use the FLIR Camera Controller GUI offered as a free download from FLIR using a

Windows based PC with the standard serial communications and components provided in the

Development Kit. This software provides remote control of various camera features and modes. The FLIR Camera Controller GUI software is compatible with Windows XP and Windows

7. The PC must have a spare serial communications port or you must use one of the Tau 640

USB accessories (VPC module or Camera Link module). High-speed communication (921600

Baud) is possible using the USB accessories.

Note

A USB to Serial port adapter is acceptable, but the data communication rate must be set to

57600 BAUD.

If your embedded or specialty applications require custom control software, a Software

Developer’s Kit (SDK) is available.

C.3 Connecting the serial communications interface using the development kit

You should have successfully operated the camera and obtained live video on a monitor as

described in paragraph C.1 “Operation of the Tau 640 camera using the Photon Accessory Kit” on page C-1.

The only additional hardware required for serial communication is a serial cable connected as shown below.

To PC serial COM port

(RS232)

To Photon


Attach one end of a standard RS-232 serial port (9-pin) PC cable to the communications port labeled RS-232 on the I/O Module. Attach the other end to the serial port on your PC. This cable should be a standard RS-232 cable, not a cross-over configured serial cable, or nullmodem cable.
