Integration
Integration
The CCD imager of the TM-6705AN can be exposed longer
than normal TV timing (1/60 sec.). This feature provides high
sensitivity for dark environment applications. Integration is
achieved by controlling the #11 pin of the 12-pin connector to Low
(GND). The progressive scanning CCD chip obtains a full frame of
resolution in progressive scan format. A frame grabber is used to
capture one frame of integrated image in non-interlace format.
Integration is achieved in the photodiode region of the CCD,
which has a built-in dark current suppression structure (hole
accumulated layer). However, in long integration the dark noise
pattern (white spots) are more visible. The dark noise increases
with a rise in temperature (doubles at every 8°C increase).
Pin Configuration
Pin Configuration
12-pin connector
1 GND 7 VD in/out
2 12V in 8 GND
3 GND 9 HD in/out
4 Video(clock) 10 Multi-shutter
5 GND 11 ROI/Integ**
6 VINIT* 12 GND
*Note 1: Pin #6 VINIT is used for
partial scan pulse width control
**Note 2: Pin #11 is ROI at ROI
control (mode T) and integration
at VGA and 0 mode.
Option 7-2 (Clock and HD, VD output)
For RS-422 output, the clock is output from pin #4 (CLK+)
and pin #3 (CLK-). HD+ (#9) and VD+ (#7) are negative common
(single ended) and the negative side is GND.
The RS-422 drive is 26LS31. If the termination resistor is
high impedance, it may work with TTL input. Please consult
PULNiX for more information.
For popular slow scan or multi sync frame grabbers, PULNiX
offers Option 7-2. Since each frame grabber has different input
connector and control pins, it is advisable to contact either the
application personnel for the frame grabber manufacturer or
PULNiX application engineers.
