AccuPiXEL Dual-tap Series
TM-4000CL
General Description
The TM-4000CL is a miniature, very high-resolution (4.2
Mpixels) monochrome progressive scan CCD camera with dual
tap output. The imager resolution is 2048 x 2048 pixels and the
frame rate is 7.5 and 15 frames per second. The interline transfer
CCD permits full vertical and horizontal resolution of high-speed
shuttered images. The electronic shutter has speeds up to
1/16,000 sec. and can be reset asynchronously by external pulse
control.
The TM-4000CL has a patent-pending, PULNiX exclusive,
built-in look-up table (LUT) and automatic dual channel
compensation. This full dynamic range control function can be
set at externally selectable knee slopes to optimize the CCD's full
dynamic range in the normal output signal range. It also provides
fast 10-bit (10-bit x 2) to 8-bit (8-bit x 2) pre-processing for
effective image feature enhancement. The camera has both
analog (multiplexed to single channel output) and digital (Camera
Link) output for interfacing with frame grabbers.
All camera control functions are externally controlled via a
user-friendly Camera Link or RS-232C graphical interface
provided by PULNiX.
Applications for the TM-4000CL include machine vision,
medical imaging, intelligent transportation systems, highdefinition graphics, gauging, character recognition, documents
archiving, and surveillance.

Electronic Shutter
The TM-4000CL 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 1/60 (non-async mode only), 1/125,
1/250, 1/500, 1/1,000, 1/2,000, 1/4,000, 1/8,000, or 1/16,000
second. (double the speed at 60 fps mode)
The CCD discharges when discharge pulse is applied via
internal shutter control. With a negative pulse to VINIT, the
camera resets and purges the CCD charge momentarily. Then it
starts integrating for the period of preset shutter control time by
either an external pulse width or internal shutter control.
Progressive scanning permits a full 2048 lines of vertical
resolution, as compared to a conventional CCD camera which
captures only half the vertical lines per shutter.

The CCD imager of the TM-4000CL can be exposed for longer
than the normal scan timing of 1/15 sec. This integration feature
provides extra sensitivity for dark-environment applications. The
progressive-scan imager permits a full frame of resolution in noninterlace format. Integration is achieved by applying INTEG signal
to pin #11 of the 12-pin connector or ccl2 control of Camera
Link, or by feeding VINIT pulse width control up to 3 sec of the
pulse width in async pulse width control mode.
AccuPiXEL Series
The TM-4000CL'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:
1 External VINIT with pulse width. The duration between pulse
edges controls the shutter speed externally.
2 Internal shutter speed control. The speed control varies from
1/125 to 1/16,000 sec. The video signal and FDV starts with
internal V reset timing related to shutter speed.

TM-4000CL Progressive Scan High-Resolution Shutter Camera
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 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.
Typical interline transfer CCDs have fixed noise levels based on
dark current (thermal or KT noise), pattern noise, and operating
clock speed. Typically for a 2k x 2k CCD operating at 40MHz pixel
clock, the noise level is around 50 electrons. The maximum
capacity of the CCD charges is limited by the well capacity at
saturation. The range is limited by the structure and the pixel size.
The TM-4000CL uses a 1.2” CCD with 7.4 µm x 7.4 µm pixel
and two-phase vertical shift register structure. The well capacity is
42,000 electrons. The theoretical dynamic range is 42,000:50 =
840:1 (58 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 has its gain 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.

Normal scanning mode for the TM-4000CL is 2048 x 2048

frames/sec at the pixel clock of 40.0 MHz*. Unlike an interlace
scan camera, the TM-4000CL reads every line from top to bottom,
resulting in all lines being obtained per captured image frame with
electronic shutter.

Machine vision and outdoor applications cannot afford to miss
image information behind the saturation, which is why the dynamic

1000 lines and 500 lines partial scan is selectable. It outputs
image center of 1000 lines and 500 lines. At 1000 lines the frame

Dual Tap Output
TM-4000 has built-in line buffers to select channel B output
direction. CCD output is split into two channels. The left half
outputs data from 1 to 1024 (ch.A) and the right half outputs from
2048 to 1025 (ch.B). The internal line buffer corrects the right half
(ch.B) output to start from 1025 to 2048 so that frame grabber
does not have to convert the pixel orders. The ch.B output
direction is selectable.

No-delay Shutter and Read-out-inhibit
For multiple-camera applications such as 2D or 3D
measurement and multi-angle inspection, simultaneous image
capturing at an exact shutter timing for all cameras is a critical
requirement. The TM-4000CL’s async 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 exactly simultaneous.
The TM-4000CL also has read-out-inhibit control (ROI) to
control the vertical clock start (Async Shutter #9). When ROI is
low, V-clock is stopped and the transferred charges remain in the
vertical shift registers, which works like CCD memory. When ROI
is high, it clocks out the CCD data. This helps a single frame
grabber process multiple images in pipeline processing
(sequential process).
