TM-6740 Series Progressive Scan
Shutter Cameras
Operation Manual
1 Introduction
1.1 Product Description
The PULNiX TM-6740 series consists of dual-tap output, high-speed progressive scan CCD cameras.1
The interline-type CCD permits full vertical and horizontal resolution of very high speed shutter images
and applications. The electronic shutter, which has speeds to 1/64,000 sec., can be reset asynchronously
by external pulse control. The frame rate for a full image is 200 fps, with partial scan mode of up to
3200 fps. A 4:3 ratio imager format with uniform square pixels provides superior image definition in
any orientation. On-chip micro lenses provide increased sensitivity.
The TM-6740 has a full dynamic range control function, which can be set at externally selectable look-
up 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. As a dual-tap outputs camera, the TM-6740 has dual-
channel auto-black level balancing2and semi-auto-gain balancing functions. The camera has a dual-tap,
10-bit/8-bit Camera Link output (see Figure 1, “CL (Camera Link) System Configuration,” on page 3).
All the key functions are controlled via a Camera Link serial communication interface.
Applications for the TM-6740 include machine vision, medical imaging, intelligent transportation
systems, high-definition graphics, on-line inspection, gauging, character reading, archiving, and high-
security surveillance.
1. The TM-6740 series consists of TM-6740CL, TMC-6740CL (Camera Link), TM-6740GE, and
TMC-6740GE (gigabit ethernet). Unless otherwise noted, all information contained in this manual
is relevant to all models.
2. Due to the CCD’s structure, auto-black level balancing works with full-image scan modes and ver-
tical partial scan modes. Auto-black level balancing does not work with horizontal partial scan
modes.

Introduction
TM-6740 Series Progressive Scan Shutter Cameras
1.2 Features
•Miniaturized and lightweight
The printed circuit boards in the TM-6740 have been arranged based on a new design philosophy.
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 50.8mm x
50.8mm x 81.5mm in dimensions, and weighs only 155 grams.
•Imager
The TM-6740 uses a dual-tap progressive-scan interline transfer CCD that has the following
features:
- Resolution of 640 x 480 active pixels for excellent image quality.
- 7.4 x 7.4 µm square pixels for precise dimensional measurement.
- High-speed electronic shutter capability for high dynamic resolution of moving objects 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 an excellent S/N ratio at the
default setting that is greater than 48dB.
- The CCD has a built-in microlens for increased quantum efficiency.
•Electronic shutter
The TM-6740 has a substrate drain-type shutter mechanism which provides superb pictures at
various speeds without smearing. For more information, please see Section 3.3, “Electronic
Shutter,” on page 13.
•Asynchronous reset
The TM-6740 captures async reset images and provides single-shot video output with single FDV.
This makes it simpler for an ordinary frame grabber to capture the async reset images. The TM-
6740CL’s asynchronous reset is flexible and accepts external horizontal drive (HD) for phase
locking. When the VINIT (5V) pulse is applied to CC1, it resets the camera's scanning and purging
of the CCD.
The TM-6740 has three modes to control the asynchronous reset and shutter speed:
- Async, no shutter. The video signal and FDV are reset by external VINIT.
- Internal shutter speed control. The speed control varies from 1/250 to 1/64,000 sec. The
video signal and FDV starts with internal V reset timing related to shutter speed.
- External VINIT with pulse width. The duration between pulse edges controls the shutter
speed externally.

TM-6740 Series Progressive Scan Shutter Cameras
•Output
The TM-6740 has a dual tap 10-bit/8-bit Camera Link output. The analog output is
714 mVp-p composite video (75 ohms) on all models.
•Dual-Channel Auto Black Level Balancing and Semi-Auto Gain Balancing
The TM-6740, as a dual-tap output camera, has auto black level balancing and semi-auto gain
balancing functions.
•Integration
The TM-6740 is capable of capturing high-resolution integration images. Its CCD imager can be
exposed for longer than the normal scan timing of 1/200 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 applying INTEG signal to CC2
control of Camera Link or by feeding VINIT pulse width control up to 1 sec of the pulse width in
async pulse width control mode for the frames to be integrated.
•Warranty
Please contact your factory representative for details about the warranty.

The TM-6740 camera accepts 1/3" or larger format size C-mount lenses. To attach the C-mount lens3to
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.
3. C-mount to F-mount and C-mount to K-mount adapters are available for larger format lenses
(35mm). Check with local photography dealers for these lens adapters.

3.2 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. This means
that 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-6740 uses a state-of-the-art progressive scanning interline transfer CCD which scans all lines
sequentially from top to bottom at one frame rate. Like a non-interlace computer screen, it generates a
stable, crisp image without alternating lines and provides full vertical TV resolution of 480 lines. Due to
the TM-6740CL’s extremely high frame rate, however, it will not synchronize to most monitors.
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.

Operation
TM-6740 Series Progressive Scan Shutter Cameras
The TM-6740 outputs the progressive-scanned image with an electronic shutter in thirty-six different
formats. See Table 3 on page 12 for more information.
1. Progressive-scanning digital and analog output
The CCD signal goes through A/D converters 10-bit in, 10-bit/8-bit out. The digital out-
put is available via the Camera Link connector.
The analog output is the same as 75 ohms, 714mV format available from BNC and 12-
pin connector.
2. Full Progressive Scan
Normal scanning mode the TM-6740 is for 640 x 480 pixels. The standard speed with
dual-channel output is 200 frame/sec at the pixel clock of 40 MHz. The progressive scan
reads every line from top to bottom and all lines are exposed with a single electronic
shutter.
FIGURE 4. Full Progressive Scan Mode (A)
3. Partial Scan Mode
By selection, the camera has three partial scan modes: centered 160 lines, centered 224
columns, and centered 224 x 160 area. In partial scan mode at 1000 lines, partial scan’s
frame rate is 28fps. 500 lines is 50 fps, 250 lines is 80 fps.
