TM-6760 Series Progressive Scan Shutter Cameras
Operation Manual
1 Introduction
1.1 Product Description
The JAI, Inc. TM-6760 series are VGA format, high-speed monochrome progressive scan CCD
cameras.
high speed shutter images and applications. The electronic shutter, which has speeds to 1/32,000 sec.,
can be reset asynchronously by external pulse control. Three frame rates are available: 30, 60, and 120
fps. On-chip micro lenses provide increased sensitivity.
The TM-6760 has a full dynamic range control function, which can be set at externally selectable lookup-table (LUT) knee slopes to convert 10-bit input to 8-bit output, thereby optimizing the CCD’s full
dynamic range in the normal output signal range. The camera has an 8-bit, RS-644 digital signal output
for interfacing with external image-processing systems. All the key functions are externally controlled
via RS-232C. The TM-6760CL model has a Camera Link output and its key functions are externally
controlled via differential serial communication of Camera Link.
Applications for the TM-6760 include machine vision, medical imaging, intelligent transportation
systems, high-definition graphics, on-line inspection, gauging, character reading, archiving, and highsecurity surveillance.

The progressive interline-type CCD permits full vertical and horizontal resolution of very
*. Unless specifically mentioned, all information in this manual is relevant to all cameras in the TM-
6760 series, including the RM-6760, RMC-6760, RM-6760CL, RMC-6760CL, TM-6760, TMC6760, TM-6760CL, and TMC-6760CL.

1.2 Features
• Miniaturized and lightweight
The printed circuit boards in the TM-6760 have been arranged with a new design philosophy in
mind. This creates modular electronics for the camera, giving it flexibility. In addition, the use of
miniature solid-state components results in a compact, lightweight camera that is 44mm x 44mm x
64mm in dimensions, and weighs only 138 grams.
• Imager
The TM-6760 uses a progressive scan interline transfer CCD that has the following features:
- Resolution of 648 x 484 active pixels for excellent image quality.
- 9.0 x 9.0 µm square pixels for precise dimensional measurement.
- High-speed electronic shutter capability for high dynamic resolution of moving objects and
electronic iris control that eliminates the need for a mechanical shutter.
- Progressive scan CCD eliminates interlace deterioration of image and increases ease of
computer interface.
- High sensitivity and low noise at fast scanning. The CCD has a clock rate faster than 25
MHz pixel and has an excellent S/N ratio that is greater than 48dB.
- The CCD for the TM-6760 has built-in microlenses.
• Electronic shutter
The TM-6760 has a substrate drain-type shutter mechanism which provides superb pictures at
various speeds without smearing. A built-in manual shutter speed control selects the electronic
shutter rate of 1/125, (non-async mode only) 1/250, 1/500, 1/1,000, 1/2,000, 1/4,000, 1/8,000,
1/16,000, or 1/32,000 second.
With VINIT high (5V), the CCD keeps discharging. With a negative pulse to VINIT, the camera
resets and purges the charge momentarily. Then it starts integrating for the period of shutter control
set by either an external pulse width or internal shutter control. Progressive scanning permits a full
484 lines of vertical resolution, as compared to a conventional CCD camera which captures only
half the vertical lines per shutter.
• Asynchronous reset
The TM-6760’s asynchronous reset is flexible and accepts external horizontal drive (HD) for phase
locking. When the VINIT pulse is applied, it resets the camera's scanning and purging of the CCD.
There are two modes to control the asynchronous reset and shutter speed:
- External VINIT with pulse width. The duration between pulse edges controls the shutter
speed externally.
- Internal shutter control mode. The speed control varies from 1/250 to 1/32,000 sec. The
video signal starts with internal V reset timing related to shutter speed.
Introduction
• Output
The TM-6760 has an 8-bit RS-644 (LVDS) digital output for interfacing with external imageprocessing systems. The TM-6760 camera is also available with RS-422 digital output as an option
(OP-93). The TM-6760CL has a Camera Link output. The analog output is 1.0 Vp-p composite
video (75 ohms).
• Asynchronous image capturing
The TM-6760 captures async reset images and provides single-shot video output with single FDV.
This makes it simpler for an ordinary framegrabber to capture the async reset images.
• Integration
The TM-6760 is capable of capturing high-resolution integration images. Its CCD imager can be
exposed for longer than the normal scan timing of 1/60 sec. This integration feature provides extra
sensitivity for applications in dark environments. The progressive scan imager permits a full frame
of resolution in non-interlace format. Integration is achieved by controlling the #11 pin of the 12pin connector to low (GND) or pulse width control VINIT to pin #6 of the 12-pin connector up to 1
second.

2.2 Camera Setup
2.2.1 Heat Dissipation
The TM-6760 camera is a compact 648K x 484K camera. Since all the electronics have been packed in
a compact package, the outer case of the camera gets hot due to heat dissipation. JAI, Inc. recommends
the following procedure for optimal performance of the camera:
1. Mount the camera on a large heat sink (camera bracket) made out of conductive
material like aluminum.
2. Make sure the flow of heat from the camera case to the bracket is not blocked by a non-conducting
material like plastic.
3. Make sure the camera has enough open space around it to facilitate the free flow of air.
4. If possible, use a cooling fan to set up a positive air flow around the camera.

Operation
3.3 Progressive Scanning
Standard TV-system scanning is 525 lines interlace scanning as specified in the RS-170 protocol. Every
other horizontal line (odd lines and even lines) is scanned at a 60Hz rate per field, and the scanning is
completed with two fields (one frame) at 30Hz rate. Because of the interlace scanning, the vertical
resolution of CCD cameras is limited at 350 TV lines, regardless of the horizontal resolution. When
electronic shutter is applied, the CCD can hold only one field of charge at each exposure. Therefore, the
vertical resolution of the electronic-shutter camera is only 244 TV lines. The situation is the same for an
HDTV-format camera, since it has interlaced scanning and the vertical resolution of the shuttered image
is 500 lines.
The TM-6760 uses a state-of-the-art progressive scanning interline transfer CCD which scans all lines
sequentially from top to bottom at one frame rate (60Hz). Like a non-interlace computer screen, it
generates a stable, crisp image without alternating lines and provides full vertical TV resolution of 484
lines (a normal TV monitor display may not be able to show images due to monitor scanning).
The interline transfer architecture is also important to generate simultaneous shuttering. This is different
from full frame transfer architecture which requires a mechanical shutter or strobe light in order to
freeze the object motion.
Page 17
TM-6760 Series Progressive Scan Shutter Cameras
The TM-6760 outputs the progressive scan image with an electronic shutter in two different formats:
• Progressive scanning digital and analog output
The CCD signal goes through A/D and D/A converters and through 10-bit in, 8-bit out look-up
table (LUT). The digital output is available from 31-pin connector with RS-644 format (25MHz
clock rate).
• Partial scan output
Partial scan: centered 200 lines at 120 frames per second.
The analog output is the same as 75 ohms, 1Vp-p format at 60/30Hz rate available from BNC and
12-pin connector.
• Two-row binning
Two-row binning combines two horizontal rows into one. This reduces the vertical resolution by
half (242 lines) and doubles the frame rate to 120 Hz. See “Scan Modes” on page 22 for more
information.
3.4 Electronic Shutter
The TM-6760 has a substrate drain-type shutter mechanism which provides a superb picture at various
speeds without smearing. A built-in manual shutter speed control selects the electronic shutter rate of
1/125 (non-async mode only), 1/250, 1/500, 1/1,000, 1/2,000, 1/4,000, 1/8,000, 1/16,000, or 1/32,000
second.
With VINIT high (5V), the CCD keeps discharging. With a negative pulse to VINIT, the camera resets
and purges the charge momentarily. Then it starts integrating for the period of shutter control set by
either an external pulse width or internal shutter control. Progressive scanning permits a full 484 lines
of vertical resolution, as compared to a conventional CCD camera which captures only half the vertical
lines per shutter.
Operation
Page 18
TM-6760 Series Progressive Scan Shutter Cameras
3.5 Integration
The CCD imager of the TM-6760 can be exposed for longer than the normal scan timing of 1/60 sec.
This integration feature provides extra sensitivity for dark-environment applications. The progressivescan imager permits a full frame of resolution in non-interlace format. Integration is achieved by
applying INTEG signal to pin #11 of the 12-pin connector or pin #6 of the 31-pin connector, or by
feeding VINIT pulse width control up to 1 sec at the pulse width. Please refer to Figure 2.2.2 on page 6
for pin-out information on the 12-pin connector.

The TM-6760's asynchronous reset is flexible and accepts external horizontal drive (HD) for phase
locking. When the VINIT pulse is applied, it resets the camera's scanning and purging of the CCD. For
asynchronous image capturing by framegrabbers, it outputs single FDV at async reset. There are two
modes to control the asynchronous reset and shutter speed:
• External VINIT with Pulse Width (no delay shutter)
• Internal Shutter Speed Mode
3.6.1 External VINIT With Pulse Width (No-Delay Shutter)
The TM-6760 can be reset with external reset pulse (VINIT). Set the dial switch to “9”. Apply a pulsewidth control VINIT signal generated from an external event trigger to the camera. The TM-6760’s
asynchronous pulse width control mode provides no-delay shutter as standard. Regardless of internal
pulse timing, it discharges at VINIT’s leading edge and transfers charges at the trailing edge of the
pulse. Even though each camera runs with slightly different H and data clock timing, image capturing is
perfectly simultaneous.
For the progressive format, one frame of video output will start from the rising edge of the pulse width
control. In async mode with external pulse input high, the video output will be disabled as the camera
continues discharging the CCD image, providing black video only.

The typical interline transfer CCD has fixed noise levels based on dark current (thermal or KT noise),
pattern noise, and the operating clock speed. In general, the level of the 25 MHz pixel clock CCD at
room temperature is around 20 to 50 electrons. The maximum capacity of CCD charges is limited by the
well capacity at saturation. The range is limited by the structure and the pixel size.
The TM-6760 uses a 1/2” CCD with 9.0 µm x 9.0 µm pixel and two-phase vertical shift register
structure. The well capacity is 32,000 electrons. The theoretical dynamic range is 32,000:60 = 533:1
(54.5 dB).
A typical CCD camera does not use the full dynamic range due to the nominal gain and the output
specification such as RS-170. The typical CCD camera’s gain is set at 16 to 22 dB and the RS-170 video
level is 714 mV. Using 20 dB gain for the calculation, CCD output is limited to 714/10 = 71.4 mV.
Since the CCD’s saturation voltage is 400 mV to 500 mV, it uses less than 1/5 of the full dynamic range.
Machine vision and outdoor applications, cannot afford to miss image information behind the
saturation, which is why the dynamic range adaptation is critical.
3.7.1 Programmable Look-Up Table (LUT) and Knee Control
The TM-6760 has a built-in LUT (look-up table) for dynamic range control.
At a specific gain setting, the offset (minimum level.... dark point) and A/D reference top voltage
(maximum level... saturation point) are set to 10-bit A/D input so that the full dynamic range of the
CCD is utilized at 10-bit references as the input and the LUT output is converted into 8-bit to adjust the
gamma correction.
The 10-bit input is segmented into two or more regions by the knee-point settings as variable gamma
selection.

3.8 Programmable LUT and Knee Control (patent pending)
The TM-6760 has a built-in LUT (look-up table) for dynamic range control. At a specific gain setting,
the offset (minimum level... dark point) and A/D reference top voltage (maximum level... saturation
point) are set to 10-bit A/D input so that the full dynamic range of the CCD is utilized at 10-bit
references as the input and the LUT output are converted into 8-bit data to adjust the gamma correction.
The look-up table has two knee points (variable gamma selection) that allow the 10 bits to be
segmented into three regions. The look-up table selection can be made either by variable knee curve or
by direct input of the knee coordinates.

3.9.3 Two-Row Binning
Two-row binning is a standard feature in the TM-6760. It is selectable and its frame rate is 120 frames
per second.
3.10 External Sync and Pixel Locking
The TM-6760 accepts an external sync of standard HD and VD at TTL level for general locking to a
system sync and clock. The external sync is only available for 60-frame mode and the frequency
requirement is as follows:
fHD = 31.486 KHz ±5%
fVD = 60.00 Hz ± 5%
(Internal Master clock = 50.00 MHz,
Pixel clock = 25.00 MHz)
3.11 Bayer Color Filter (TMC-6760 and TMC-6760CL)
JAI, Inc. AccuPiXEL series color cameras are high-resolution, high-speed progressive scan CCD
cameras. The interline transfer, progressive scan CCD permits full vertical and horizontal resolution of
Operation
Page 23
TM-6760 Series Progressive Scan Shutter Cameras
images acquired at very high shutter speeds. The electronic shutter, which has speeds to 1/16,000 sec.,
can be reset asynchronously by external pulse control. Uniform square pixels provide superior image
definition in any orientation. On-chip micro lenses mean increased sensitivity.
3.11.1 Color Filter Array
JAI, Inc. AccuPiXEL cameras use Bayer CFA (color filter array) as their standard primary color filter.
This filter provides the most popular color interpolation supported by numerous software suppliers.
The digital format, either Camera Link or RS-644, allows the camera to output accurate pixel data,
including the color information. When the data is stored in the frame buffer of a framegrabber or
computer, the color information is easily manipulated to restore the original color images. Because the
color filter array contains only a single R, G or B color in each pixel, the restored image has to fill in
colors in the missing pixel locations. The software uses neighboring pixel information to “guess” the
missing colors to make smooth, clear images. This is called “Color Interpolation.” Today's high-speed
computers allow such color interpolation to be done almost in real time. Because these cameras do not
contain internal color-processing circuitry, they are smaller and less expensive than full-function color
cameras.
3.11.2 Bayer Color Filter Array (CFA)
The Bayer CFA is an R, G, B primary color filter array. This is the most widely accepted CFA for the
single-chip CCD progressive scan format. This type of array layout has a specific order for each color’s
pixels. Since the human eye’s resolution and color recognition are highest at green, the CFA contains
two greens per each red and blue.
It is critical for the framegrabber and color interpolation to know where the individual color pixels exist
relative to sync (LDV and FDV) timing.

3.11.3 Starting Pixel Configuration
All manufacturers produce identical Bayer CFAs, but there are slight differences between the CCDs
produced by different manufacturers. The first line is generally R and G, except for the Kodak CCD,
which starts with G. The Sony CCD starts with R. The camera timing can be adjusted to start with either
G or R by skipping the very first pixels at each line. Most color interpolation software can select
between a variety of pixel relations, such as R/G start or G/R start, as well as G/B start and B/G start.
Once the correct scanning is configured, the rest of the interpolation will be exactly the same. Please
contact JAI, Inc. for further information regarding CCD manufacturers.

3.11.4 Sync and Data
The individual color data is exactly the same as the pixel data. This means that the timing relationships
of the color cameras are also the same as those of the B/W cameras. For a detailed timing chart, please
refer to each B/W camera’s data sheet and manual. If the framegrabber has a standard B/W
configuration file, then AccuPiXEL color cameras can use that configuration file to operate. The
configuration file may vary, depending on whether the output is standard (RS-644) or Camera Link.
Please consult JAI, Inc., or your framegrabber supplier for compatibility information.
The following diagram is an example of the TMC-6760 (same as TM-6760).

It is important to meet the exact starting pixel at LDV and the starting line of FDV. If the starting pixel
or line is shifted due to the image capture configuration, then the interpolation software can be adjusted
for the correct starting point. In Figure 10 on page 24, left diagram, if the first pixel is shifted (missed),
the color interpolation should start with R-G. If the first line is missed, the interpolation order will be
B-G.
3.11.5 Camera Functions
AccuPiXEL color cameras perform all functions the same way as B/W cameras. However, because of
color characteristics, the following issues are different:
• Two-row binning scan
When two rows are mixed in the CCD, the Bayer color is no longer valid. It provides color information but cannot be interpolated as a Bayer CFA.
• LUT (Look-up Table)
LUT is a powerful tool to adjust the dynamic range as well as color dynamic range. Since human
color perception is non-linear, LUT selection can help optimize color contrast by selecting the LUT
value. Gamma 0.45 is logarithmic and is closed to human perception.
When LUT is selected, black-level adjustment must be more accurate than for B/W cameras.

3.11.7 Color Interpolation
The Bayer pattern color filter array (CFA) consists of R, G, and B primary colors. Each pixel represents
one of three colors. In order to display or print color images, the signal has to be converted to RGB
output, which has three independent channels (outputs) and sync signals.
Color interpolation software or firmware performs the color by filling the
missing color pixels with neighboring pixels. It then separates the single
stream of data (8-bit or 10-bit) into three (RGB) data streams (8-bit x 3) and
adds the color matrix to adjust and balance each of the R,G, and B channels
(white balance or color balance).
The image quality depends on the camera’s own pixel data (including pixel
data independency from neighboring pixels, noise and color filter), and
interpolation of the software algorithm such as 3 x 3 interpolation, 2 x 2
interpolation, color matrix, white balance capability, etc.
All AccuPiXEL color cameras are carefully designed for maximum color performance. JAI, Inc.
strongly suggests that you use digital output for the best performance.
Some software is used on board (FPGA or DSP) to perform the interpolation. Other software simply
uses the host computer’s memory and CPU. The process speed may vary depending on the architecture
and speed of the computer.
