Figure 5.1 Camera Block Diagram
All controls and data processing of VC2 cameras are carried out in one FPGA chip. The FPGA generally
consists of a 32 bit RICS Micro-Controller and Processing & Control Logic. The Micro-Controller receives
commands from the user through the Camera Link interface and then processes them. The Processing &
Control Logic processes the image data received from the CMOS sensor and then transmits data through
the Camera Link interface. And also, the Processing & Control Logic controls the trigger inputs and strobe
outputs which are sensitive to time. Furthermore, SDRAM and FLASH is installed outside FPGA. SDRAM is
used for the frame buffer to process images and FLASH contains the firmware that operates the MicroController.

voltage output (Users need to purchase the power adaptor separately).
Precaution for Power Input

Make sure the power is turned off before connecting the power cord to the
camera. Otherwise, damage to the camera may result.

If the camera input voltage is greater than 16 V, damage to the camera may result.

Camera Features
Area Of Interest (AOI)
The Area of Interest (AOI) feature allows you to specify a portion of the sensor array. You can acquire only
the frame data from the specified portion of the sensor array while preserving the same quality as you
acquire a frame from the entire sensor array. AOI is determined as the overlapping area of two areas when
designating start point and end point in horizontal and vertical direction as shown in the figure below. Start
point and End point mean the starting and end of the AOI. In the VC-2M and VC-4M models, the frame rate
will increase as the vertical AOI is made smaller. However, the horizontal AOI does not affect the frame rate.
In the VC-3M and VC-25M models, the frame rate will increase as both the vertical and horizontal AOI are
made smaller.

Binning (VC-25M Only)
Binning has the effects of increasing the level value and decreasing resolution by adding the values of the
adjacent pixels and sending them as one pixel. VC-25M provides two binning factor (×1 and ×2) that the
user can apply both horizontally and vertically. The below figure shows application of 2 × 2 binning, four
pixels are summed and reported out of the camera as a single pixel. Using binning reduces the resolution of
camera’s imaging sensor in half, however, it results in double signal to noise ratio with the same brightness
as an original image. Binning Factor is set using “sbf” command.
Figure 8.2 2 × 2 Binning
Even if the binning is performed on the color camera, the resulting image will be
monochrome.

Exposure
The CMOS sensor of VC series uses global shutter that exposes the entire imager simultaneously. The
below figure illustrates the timing of exposure and readout of CMOS sensor. Readout is performed
consecutively from first to last line where readout defines the process of reading the accumulated charges on
pixels. Readout Time (also called Transfer Time) defines the rate at which one frame of an image is
transferred.

Trigger Mode
Trigger mode of the camera is divided into Free-Run mode where image is synchronized to Internal Trigger
signal created inside the camera and External Sync mode where image is synchronized to the trigger signal
entered into the external port.
8.4.1
Free-Run Mode
In Free-Run mode, the period of internal trigger signal is determined by Transfer Time (1 Frame data
transmission time) and Exposure setting value, and image is obtained with this periodic signal. Frame Rate,
the period of internal signal, is determined with the following two conditions.

Case 1: Exposure Time < Frame Transfer Time
-

Frame Rate(FPS) = 1 / Frame Transfer Time (sec) → has a fixed value.
Case 2: Exposure Time > Frame Transfer Time
-
Frame Rate(FPS) = 1 / Exposure Time (sec) → varies depending on Exposure Time value.

External Sync Mode
In External Sync Mode, camera keeps standby status until trigger signal is entered, and when trigger is
entered, the image is transmitted (frame transfer) after exposure process. To operate the camera in External
Sync mode, it is required to set Trigger Source regarding which input, CC1 input port or External Trigger port,
will be used for trigger signal, as well as Polarity and Exposure source of the signal entered.

Overlap Trigger Input
When trigger is entered during frame transfer as shown in the figure below, it performs exposure process for
newly entered trigger while transferring the previous data. In this case, shooting images is possible up to the
maximum frame rate (speed of 1/Transfer Time (sec)) regardless of the exposure time.

Figure 8.7 Camera Operation when Overlap Trigger is entered
Following list shows the operation of camera on exceptional trigger input.

When the trigger signal with the faster period than the maximum frame rate condition is entered, the
next frame transfer is performed before completing the previous frame transfer. This causes the failure
of obtaining overall image.

If new trigger is entered during the exposure process after Exposure Source is set as Program, the
newly entered signal will be ignored. In this case, exposure time is longer than trigger input period and
the frame rate will be slower than trigger input period since all the entered trigger signals cannot
synchronize.

Defective Pixel Correction
The CMOS sensor may have Defect Pixels which cannot properly react to the light. Correction is required
since it may deteriorate the quality of output image. Defect Pixel information of CMOS used for each camera
is entered into the camera during the manufacturing process. If you want to add Defect Pixel information, it is
required to enter coordinate of new Defect Pixel into the camera.
For more information, refer to Appendix A. “sdc” command is used to set whether to use Defective Pixel

8.14 Dark Image Correction
CMOS sensor may result in lower sensitivity at dark level. This is caused by fixed pattern noise variation
depending on the exposure settings or characteristic change according to the temperature variation of AFE
and sensor cell. Sensitivity change resulted by temperature variation is less than 1 ㏈/10 degree. The
acquisition condition of correction data is 25 degree based on the camera case temperature. To acquire
optimized image at user environment, it is recommended to perform dark image correction after the camera
is installed and the temperature of the camera is stabilized.
VC-25MC-30 does not support dark image correction.

8.15 White Pixel
If you use a VC-25M camera under the condition of high ambient temperature, white pixels (also known as
hot pixels) may be occurred due to the characteristic of equipped high resolution CMOS sensor.
White pixels are caused by accumulated current leakage in the charge storage region inside the imaging
sensor’s active pixel. If temperature is increased by seven degrees, it is getting worse with double white
pixels.
To effectively reduce white pixels, maintain the operating temperature as low as possible and mount the
camera on a substantial metal component in your system to provide sufficient heat dissipation. You can also
use the defective pixel correction to remove white pixels. Add a defective pixel to defective pixel map or
modify the defective pixel map stored in the camera.

Actual Time Applied for Commands
When you execute a command, the actual or real time applied for the command varies depending on the
type of the command and operating status of the camera.
All commands except Set Exposure Time (‘set’) command are applied to change the settings as illustrated
below, on the rising edge of a VCCD signal before starting readout process.
When you execute a ‘set’ command, the exposure time setting will be changed at the starting of the
exposure.
In the Trigger mode, you must execute commands before applying trigger signals in order to synchronize
image outputs with the commands.
In the Free-Run mode, even if you execute a command, you may acquire up to two images without applying
the command. This is true because it is hard to verify the current operating status of the camera in the FreeRun mode.

Parameter Storage Space
The camera has 3 non-volatile storage space used for parameter storage and 1 volatile work space that is
applied to actual camera operation. 3 storage space is divided into Factory Space that contain basic value at
the factory, and 2 user space (User Space 1, User Space 2) that can save parameter value temporarily set
by the user. User space can be read and written, but Factory space can be read only.
At camera booting, setting value in one of 3 storage spaces is copied to work space according to Config
Initialization value and value of the space is used for camera setting. Since values in work space is valid only
while the power is on, it should be copied to user space 1 or user space 2 using “sct” command.

10 Configurator GUI
Configurator, a sample application, is provided to control VC Series camera. Configurator provides easy-touse Graphic User Interface (GUI) for the user while using the commands mentioned previous chapters.
10.1 Camera Scan
When you execute the program while the camera is turned on, Camera Scan window appears as shown in
the figure below. At this time, the program checks serial port of computer and DLL provided by Camera Link
to scan whether the camera is connected. If there is a camera connected, it displays model name on the
screen. If the camera is not properly displayed on the screen, check the connection of cable with power of
camera and press the refresh button. When you double-click model name displayed on the screen,
Configurator is executed and displays current setting value of camera connected.
