TM-1300 PROGRESSIVE SCAN
HIGH RESOLUTION SHUTTER CAMERA
General Description
General Description
The PULNiX TM-1300 is a very high resolution (1300 x
1030 active pixels, 5:4 aspect) monochrome CCD camera
which uses a progressive scan interline transfer CCD with a
single channel output to achieve outstanding shutter and
integration characteristics. It is specifically designed for low
noise and high resolution image capturing with externally
controlled gain and dynamic range adjustments which extract
the best imaging performance from the CCD. The electronic
shutter, which has speeds selectable to 1/39,000 sec., may
be asynchronously reset by external pulse control.
The TM-1300 has its own 8-bit built-in frame store which
can capture and output full-frame images in real time. At 10-bits,
the RS-422 digital signal output is provided for interfacing with
external image processing systems. The SVGA display output
provides a great convenience for video monitoring with a
standard computer monitor. Special interface cables are
available for connecting the TM-1300 directly to many existing
commercial frame grabbers. All functions are remotely controllable
via RS-232C (or RS-485) communication.
Applications for the TM-1300 include medical imaging, high
definition graphics, on-line inspection, gauging, character reading,
archiving, intelligent transportation systems, and long range
image acquisition.

The TM-1300's asynchronous reset is flexible. CCD scanning
and purging is reset by applying the VINIT pulse. There are three
modes to control the asynchronous reset and shutter speed:
1. Internal shutter speed mode. The speed control can be
selected from 1/50 to 1/39,000 sec., with a standard output of 12
frames per second (FPS). The video signal starts with internal
V-reset timing related to shutter speed. The built-in frame memory
can maintain the asynchronously captured full frame image until the
next VINIT pulse comes in (memory mode).
2. Direct shutter mode. Selectable from 1/39,000 to 1/12, in
increments of one horizontal scan time.
3. Async Reset with no shutter. Video images are acquired at
1/12 of a second, with no electronic shutter. Shuttle dial switch
position is set to the zero position.
Integration
Integration
The CCD imager of the TM-1300 can be exposed longer
than normal scan timing (1/12 sec.). Integration is achieved by
controlling the #11 pin of the 12-pin connector to Low (GND).
This integration feature provides high sensitivity in dark environ-
ments. The internal frame memory provides continuous video
output without interruption during the integration period. The
progressive scan CCD chip permits a full frame of resolution in
non-interlace format. Designed for low noise applications, the
integration mode and slower clock scanning with 10-bit output
make this camera suitable for a variety of applications.

The TM-1300 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 1/50, 1/100, 1/200, 1/400, 1/1,500,
1/3,000, 1/5,500, 1/9,500 or 1/39,000 second. With VINIT high
(5V), the CCD keeps discharging. With a negative going pulse to
VINIT, the camera resets and purges the charge momentarily.
Then it starts integrating for the period of shutter control set by
internal shutter control. A full 1030 lines of vertical resolution per
single shutter is available, as compared to a conventional CCD
camera which allows only half lines per shutter.
