TM-4000CL

AccuPiXEL Dual-tap Series

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 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 serial graphical interface

provided by PULNiX.

Applications for the TM-4000CL include machine

vision, medical imaging, intelligent transportation systems,

high-definition graphics, gauging, character recognition,

documents archiving, and surveillance.

Asynchronous Reset

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.

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.

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.

Integration

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 non-interlace format.

Integration is achieved by applying INTEG signal to the ccl2

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.
