TM-75/76 High-Resolution CCD Camera
Operation Manual
1
Introduction
1.1 Product Description
The TM-75 is specifically designed to be a replacement for SONY’s XC-75 camera. It is an inexpensive
yet high-quality camera that meets a variety of application requirements. This miniaturized highresolution camera features an advanced Hyper-HAD* interline transfer 1/2" CCD imager, and offers
many standard and optional features at a very affordable price. A CCIR-format model, the TM-76, is
also available.
1.2 Features
•
Variable electronic shutter
The substrate drain-type shutter mechanism provides a superb picture at various speeds without
smearing. The electronic shutter rate can be adjusted from 1/60 to 1/10,000 (1/29,100 in some
operating modes) in discrete steps.
•
Miniaturized and lightweight
The use of a CCD image sensor in the video camera module and mini C-mount lenses make it
possible to produce a very compact, lightweight and robust camera small enough to operate just
like a remoted head.
•
High sensitivity
The TM-75/76 camera is one of the most low-light sensitive 1/2" CCD cameras available today.
This feature is especially important when using the faster shutter speeds. It requires only 1.0 lux of
minimum illumination and 0.5 lux minimum illumination at maximum gain. In general, this allows
the use of a higher lens F-value while providing a greater field depth and sharper images.
•
Reset-restart and external trigger mode
*. Hyper-HAD is a trademark of SONY Corporation.
TM-75/76 High-Resolution CCD Camera
Page 2
Introduction
The camera can be reset at random timing to restart. It will also take an external trigger signal to
control shutter and reset timing for asynchronous image capturing.
•
Low lag/high resistance to image burning
Because the CCD is highly resistant to image burning, the camera may be exposed to bright objects
for a long period of time. Because a “smear” phenomenon may occur when shooting a very bright
object, an infrared cutoff filter is standard to obtain a clear picture.
•
AGC/MGC selection, manual gain control and gamma adjustment
These adjustments, which are particularly important in vision system applications, are adjustable
via internal switches.
•
Genlock circuit
A genlock circuit is built in to accept external sync for applications in which external sync is
required.
•
High resistance to magnetic field and vibration/mechanical shock
The CCD imager’s rugged design allows it to withstand strong vibration and shock with little or no
noise appearing in the picture. Since the TM-75/76 is not influenced by a magnetic field, it will
produce stable images even when placed next to objects such as electric furnaces, welding
machines or NMR scanners.
•
Quick start-up and low power consumption
Image capture can begin within a fraction of a second after turning on the camera. The power
consumption is only 2.3W, 190mA @12V.
•
Camera mounting flexibility
The TM-75/76 has tapped M3 holes on the top and bottom. A tripod mount is available as an
optional accessory.
•
Three-year warranty
The CCD solid-state image sensor allows the camera to maintain a superior performance level
indefinitely while requiring virtually no maintenance. PULNiX backs all of the TM series cameras
with a three-year warranty.
Warning:
Unscrewing the camera cover or opening the camera in any way
will void this warranty unless prior written approval is
obtained from the factory.
1.3 Functional Options
•
Optical Filter Removal (OP3-2) (TM-75/76 comes with an IR cut filter as standard equipment).
•
Glassless CCD Imager (OP21)
•
DC Coupled (OP72)
•
NIR CCD
1.4 Applications
The miniature size of the TM-75/76 camera eliminates the need for a remoted imager camera in all but
the most confined spaces. This camera fits easily, both physically and functionally, into all types of
machine vision, automated inspection, and related applications. Other uses include remotely piloted
vehicles, miniature inspection devices, surveillance, microscopes, and medical equipment.

3.
Plug the power cord into the 110V AC socket (or the proper AC line). This will power the camera
up.
2.2.3 Attaching the Video Output
Most users utilize the BNC connector for video output from the camera. Connect the output from the
camera to the input of your monitor, VCR, or switching device. The input of the monitor should be
balanced for 75Ω termination. Standard RG-59 type coaxial cable should carry a full video signal for up
to 500 feet.
To output the video and input the power and sync to a camera over a single cable, use the PULNiX
multi-conductor cables, such as the 12P-02S, etc. The mini coaxial leads in PULNiX multi-conductor
cables are designed for short runs of no longer than 100 feet.
Note:
Make sure that no extraneous wires are visible which could cause a short.
2.2.4 Attaching the Camera Lens
The TM-75/76 camera accepts 1/2" or larger format size C-mount lenses. To attach the C-mount lens to
the camera, carefully engage the threads and rotate the lens clockwise until it firmly seats on the
mounting ring. Do not force the lens if it does not seat properly. Please note that some lenses with
extremely long flangebacks may exceed the mounting depth of the camera.
2.2.5 Auto-Iris Lens Setup
Auto-iris lenses with full video input can be used with the PULNiX TM-75, although this camera model
does not come equipped with auto-iris output.
Note:
Make sure that the power is removed from the camera before connecting or disconnecting
the auto-iris lens. There is a small chance that the auto-iris lens could be damaged by
plugging or unplugging it while the camera is powered up.
Power down the camera before installing the auto-iris lens. To install the auto-iris lens in a PULNiX
camera for which the auto-iris input is not supplied, wire the signal (video) on the lens into the terminal
1 Vp-p video output on the camera.
Point the camera at a light area and then quickly towards a darker area. If everything is working
properly, the iris should adjust for the light change.
2.2.6 Monitor Display Mode
For monitoring real-time video, connect the video output to a video monitor or other device.

Note:
In order to enable Reset-Restart sync pulse, F2 function selection must be ON. Normal
external VD is detected automatically when F2 is OFF. In this mode, if there is no external
VD, internal VD is automatically generated.
3.1.3 Field and Frame Modes
The standard factory setting for the TM-75/76 camera is FRAME MODE. The field and frame
integration mode is selectable using the #2 switch of the mode switch inside the camera. The frame
integration is used to separate all CCD pixels. The exposure of Odd and Even fields generates the full
frame image shown in Figure 3, “Field/Frame Diagram,” on page 10.

3.1.3 (a)
Field Mode
In Field mode, two horizontal rows are scanned simultaneously. At each interlace scan, the scanned
pairs are changed. Thus the sensitivity of the CCD is doubled for one field of integration. When
compared to Frame mode, in which each horizontal row is scanned separately, Field mode obtains the
same sensitivity in half the time period. The field integration is done by combining two pixel rows
(binning) together and each pair alternates as interlace scan is generated. Row 1 is binned with row 2,
and row 3 is binned with row 4. In Field 2, row 2 is binned with row 3, row 4 with row 5, and so on. The
field mode is very effective in shutter mode since the pixel sensitivity is doubled for field integration (1/
60 sec) and equals with frame mode (one row at 1/30 sec). Since shutter mode is only one field output
per shutter and darker than normal image, two-row binning is effective. This mode also reduces interlace
moire when a sharp horizontal pattern is observed.
Moire is unnoticeable because of alternating two-row scanning. The vertical resolution in Field mode is
not as good as that in Frame mode, but it is sufficient to view the full vertical resolution of the TV
format.
Note:
1. Since only one field are output in the Field mode, it cannot provide full frame resolution
in strobe lighting applications.
2. The TM-76(CCIR) is 1/50 sec. for Field and 1/25 sec. for Frame mode.
3.1.3 (b)
Frame Mode
In Frame mode, each horizontal row is scanned as interlace scanning. The integration of each pixel is
one frame period. In Frame mode, vertical pixel resolution is good, and the exact location is obtained. In
comparison with Field mode, however, Frame mode has the disadvantage of showing vertical Moire.
Frame mode should be used in applications that need strobe lighting, because full frame resolution is
achieved in this mode. For higher pixel definition such as gauging and sub-pixel interpolation, Frame
mode operation is recommended.

3.2 Operating Modes
Besides normal operation, the TM-75/76 supports the following versatile operations that can be
selected:
•
Standard Interlace Mode
Field integration Mode
Frame Integration Mode
•
External Sync Mode
•
Interlace Scan Mode
•
Non-interlace Scan Mode
•
Reset-Restart Mode with Electronic Shutter

Trigger Position Mode
Snapshot Mode (Donpisha Mode)
3.2.1 Standard Interlace Mode
See Section 5, “Operation Mode,” for setting and operation of modes.
3.2.1 (a)
Field Mode and Frame Mode
The field and frame integration mode is selectable. The frame integration is used to separate all CCD
pixels and the exposure of Odd and Even fields generate the full frame image shown in the figure below.
3.2.1 (b)
Field Mode Binning
The field integration is done by combining two pixel rows (binning) together, each pair alternating as
interlace scan is generated. Row 1 is binned with row 2, and row 3 is binned with row 4. In Field 2, row
2 is binned with row 3, row 4 with row 5, and so on.
3.2.2 Cyclic (Continuous) Shutter Mode
With rotary switch shutter control, the TM-75/76 operates at the internally predefined shutter speeds.
Each field output is exposed for the same period. The shutter control varies the substrate discharge
timing. The duration between the shutter pulse and transfer gate timing (9.5H from VD leading edge for
EIA, 14.5H for CCIR) decides the exposure time. The following four cyclic shutter modes are available:
•
High-Speed Cyclic Shutter mode
•
Trigger Position Reset/Restart Shutter mode
•
Trigger Width Reset/Restart Shutter mode
•
Snapshot Reset/Restart Shutter mode
Contact PULNiX for timing charts of various cyclic shutter modes.

Operation
3.2.3 External Sync Mode
TM-75/76 accepts standard RS-170 external sync, which is defined as horizontal sync (HD) and vertical
sync (VD). The phase-locked loop jitter is designed to be the minimum (< 5ns) in this category using the
latest PLL chip. The wide capture range enables the camera to operate at an extended temperature range
(optional) of -35°C to 65°C. HD and VD input is TTL level and the input impedance is 75Ω.
3.2.4 Reset-Restart Mode
The camera can be reset asynchronously using EXT VD. In this mode, the camera needs multiple VD
pulses to output valid images, depending on whether it is set to Field or Frame mode. Usually, the first
field (Field mode) or the first frame (Frame mode) are garbage because of previous signal residuals prior
to reset. A frame grabber has to know which frame or field to capture. External HD also must be applied
for this operation.
3.2.5 External Shutter Control
The shutter speed or exposure can be controlled with external pulse (TRIG) in this mode. In
combination with Reset-Restart Pulse (EXT VD), the camera can be externally controlled for imagecapture timing as well as for exposure time.
This is an excellent application for capturing multiple images (two fields of images) of indexing objects
under various lighting or brightness conditions. When Frame mode is selected, the full vertical
resolution is achieved by taking two fields of shutter images, whether or not you are using an electronic
shutter.
3.2.6 Non-Interlace Operation
With non-interlace external sync, the camera operates at non-interlace scanning. External VD for TM-75
must be generated at integer of 262H ± 8H (Standard interlace is 262.5 H). For the TM-76, it must be
312H ±8H, and the interlace scan is 312.5H.
TM-75/76 High-Resolution CCD Camera

TM-75/76 External Signals

TM-75/76 External Signals
This section explains how the external signals (HD and VD) and shutter trigger signal (TRIG) must be
fed in External sync (HD, VD sync) and Reset-Restart operation.
4.1 External HD
When external HD is supplied to pin #6 of the 12-pin connector, the TM-75/76 automatically switches
the clock to phase-lock to the external clock via HD PLL (phase lock loop). The PLL detects the leading
edge of external HD and Phase compare with the internal HD. Then PLL circuit generates internal clock
to phase-lock with the external clock. Therefore, the leading edges of both external and internal HD are
in exactly the same position. The PLL capture range is ±5% of fHD (=15.734KHz: EIA, 15.625: CCIR).
It is, however, advisable to stay within ±1% of fHD frequency to assure the best PLL jitter
characteristics. Without the presence of external HD, the TM-75/76 maintains the internal sync. The
input impedance of external HD and VD is 75Ω at factory set. A high-impedance option is also
available.
4.2 External VD
The TM-75/76 interface circuit deliberately delays external VD by two pixel clock (14 nsec) to ensure
the stable reset of VD in relation to external HD.
FIGURE 4.
External Vd Delay Timing
EXT HD
EXT VD (R.R.)
Two-pixel delay
Internal VD
For HD, VD external sync operation, apply VD to pin #7 of the 12-pin connector. The input impedance
is 75Ω. The VD reset range is from 244H to 1023.5H. For normal RS-170 operation, the VD must be
interlace scan at 262.5H (59.94 Hz = 16.7 msec). At 525H, it generates one full frame timing. The
integer (i.e. 262) reset makes non-interlace sync operation. Half H number (i.e. 262.5) makes interlace
scanning.
Note: The TM-76 vertical scan is 625H. VD is defined as 312.5H (50Hz).
4.3 Reset-Restart VD
For Reset-Restart VD operation, VD is asynchronous in relation to any previous VD. Depending on
field or frame mode, however, once the first VD is asynchronously set, consecutive VD must be
generated to obtain proper images. I n general, the first field in field mode or the first frame in frame
mode is not usable because they are previous images prior to reset. A frame grabber has to know which
frame or field to capture. External HD must be applied for this operation.
TM-75/76 High-Resolution CCD Camera

TM-75/76 External Signals
For External HD, VD sync mode or Reset-Restart mode selection, please refer to Section 3.1.1, “Mode
Selection,” on page 8. Mode switch F2 must be set to ON for R-R mode and keep it OFF for normal HD,
VD external sync mode.

4.4 External Trigger (TRIG) and Internal Sampling Clock
To ensure stable operation without the influence of jitter, the TM-75/76 samples shutter trigger pulse
(TRIG) by internal sampling clock (LCLK) and detects the low to high level change of TRIG. The
sampling occurs only at HD leading edge timing to generate the internal TRIG as shown below.
Therefore, the external TRIG pulse must be wider than 1H (64 µsec) for pulse width and pulse position
shutter control. All trigger pulse modes must work with Reset-Restart VD, which is described in
Section 5, “Operation Mode,” The TRIG input is pin #9 of the12-pin connector and the input impedance
is 100Ω.

4.5 Trigger Pulse for Pulse-Width Shutter Control
In pulse width shutter control mode, the leading edge and trailing edge of TRIG must be synchronized
with external HD. The duration must be longer than 1H. If TRIG does not meet these conditions, the
exposure time may vary depending on the trigger position in one field to another field.

4.6 Trigger Pulse for Snapshot Shutter Control (Donpisha Mode... No Delay Shutter)
For snapshot mode (Donpisha shutter), the TRIG pulse width can be wider than just 2 pixel clocks wide
(>150nsec) since this mode only requires pixel clock data strobing. The internal TRIG is generated at
any random point and stays high until transfer gate pulse is completed.

Operation Mode
5.1 No Shutter Cyclic (Continuous Sync) Operation
In Cyclic operation mode, the camera generates its own synchronization signal by itself. It continuously
(cyclically) transfers photo charge at every VD (Vreset) in internal or external HD, VD sync mode.
Since no discharge occurs, the one full frame (1/30 sec or 1/25 sec) is the exposure time for both fields
in frame accumulation mode. In frame mode, single shot strobing or LED flash can generate a full frame
resolution with frame (two fields) image capturing. In field mode, the accumulation is for 1/60 or 1/50
sec but by taking two fields (one frame) full frame resolution can be achieved. However, strobe lighting
only generates one field image.

5.2.1 Field Mode Integration
Field mode integration is implemented by scanning two rows together (binning) and each pair alternates
as interlace scan is generated. In Field 1, row 1 is binned with row 2, row 3 with row 4,and so on.
In Field 2, the pairs change to row 2 and 3, 4 and 5 and so on. This field mode accumulation is effective
for electronic shutter applications as it generates twice as sensitive an image as frame mode. The
electronic shutter output is always one field image per shutter.

5.2.2 Continuous Shutter
In this shutter mode, the camera generates its own sync signal and continuously (cyclically) carries out
the internal shutter operation set by rotary switch. The discharge and transfer repeats in every field at a
predefined shutter speed. The discharge pulses occur in every horizontal line (in blanking) and stop at a
predefined shutter timing in one field. The duration between the last discharge and transfer determines
the exposure time.

5.3 Snapshot Reset-Restart Shutter (Donpisha Shutter)
In this mode the shutter trigger pulse (TRIG) should be 150 nsec (two pixel clock) or wider. Snapshot
mode is similar to Pulse Position mode. However the leading edge of TRIG pulse in snapshot mode
immediately produces discharge pulse without delay (means Donpisha= no delay) and starts exposure,
which enables very high speed shutter up to over 1/1,000,000 sec (1 µsec exposure). It can, in theory, go
to a 70 nsec exposure time.
The transfer (read out) occurs at 9.5H (TM-76 is 14.5H) line from VD (R-R VD) leading edge.
TRIG pulse timing can be anywhere. However, when the pulse is generated during active video period,
white noise of the pulse location may appear (faster than 1/1000 sec shutter is inside Vertical blank
period and no noise will be seen).

5.4 Pulse Position Reset-Restart Shutter
The shutter trigger pulse (TRIG) is required to be wider than 1H (>70 µsec) for this operation. Like
continuous shutter mode, the last discharge pulse occurs as external shutter control. The position is
determined at 1H after the detection of the TRIG pulse edge. The transfer (read out) occurs at 9.5H
(14.5H for the TM-76) from reset-restart VD leading edge. The minimum exposure time is 0.5H (34.4
µsec). Because the shutter operation is synchronized with an internal horizontal clock, a stable exposure
time is assured even though TRIG is applied with minor variation relative to the HD timing. In order to
avoid flickering between each field exposure, it is advisable to synchronize the TRIG with reset-restart
VD. If one frame (two fields) of shutter images are required, the TRIG pulse must be synchronous to the
interlace scanning relationship.

5.5 Pulse Width Control Reset-Restart Shutter
The shutter Trigger (TRIG) pulse is required to be wider than 1H (70µsec). The minimum exposure time
in this mode is 2.5H (1/6200 sec). In this mode, the position of TRIG does not have to be synchronized
with Reset-Restart VD (Ext. VD) and it can be asynchronous trigger with moving object. The exposure
is set by rising edge and falling edge of TRIG pulse, which can be any timing (asynchronous). The video
output is, however, synchronous with R-R VD. Since the vertical shift register must wait for completion
of TRIG and next VD, only one field of image is valid after TRIG pulse. If continuous shutter control is
required with pulse width control, the TRIG falling edge must be within 9.5 H (14.5H for TM-76) from
each VD leading edge. To avoid any image flickering between odd and even field, the TRIG pulse is
required to synchronize with HD and Reset-Restart VD.

C-Mount Custom Options
There are two custom options available, as follows:
•

Flange Surface of
C-Mount
The flange-back length of the CS-Mount is 12.5mm versus 17.526 of the C-Mount. The shorter flangeback length of the CS-Mount allows room for the stripe filter incorporated in the color camera.
Additionally, the shorter flange-back length allows for reduction of the effective diameter of the first
lens and reduces the number of lens elements. The common C-Mount lens is completely compatible
with a CS-Mount camera when a 5mm extension ring is inserted between the lens and the camera.
•
Backfocus adjustable front end
For close-up and specific backfocus requirements, this front end comes with an adjustable C-mount
ring.
