1. Product description
Model CS3920 is an integrated (one-body) type B/W CCD camera employing a 1/2”
type frame-read-out CCD, featuring its ultra-high resolution of active 2,000,000 pixels.
2. Features
(1) Ultra-high resolution
CS3920 features an ultra-high picture resolution through the adoption of a MEGA-pixel
CCD (Total pixel counts: 2,100,000 Active pixel counts: 2,000,000 [1,636(H)×
1,236(V)].
(2) Square grid pattern CCD
Pixel's in this CCD are aligned in square grid pattern. This makes it easier to perform
computation correctly for image processing use.
(3) Random trigger shutter function
Random trigger shutter, which starts light-exposure in synchronization with external
trigger signals, is build in. This function enables the camera to capture images at any
given timing. Shutter speed is selectable among 8 scales, from 1/30s through 1/10000s.
(4) Digital output
Other than conventional analog output, digital output (EIA-644 single channel 10 bit) is
also available.
(5) High-speed draft mode
By reading out just 2 lines out of total 8 lines, pixel data in all effective image area are
read out in just 1/4 of the time needed under frame read-out mode. Under the high-speed
draft mode, output lines will be 325 lines.

(4)FLD Output / FRM Output Selection (SW1 DIP7) (Initial-Factory-Setting: OFF)
OFF: Field output
ON: Frame output
Under OFF (= FLD) setting, only the 1st field data is output in response to one trigger
input. Under ON (= FRM) setting, both the 1st and 2nd field (=1 frame) data are output
in response to one trigger input. Under the FRM output setting, CCD exposure is done
twice inside the camera. This causes 1-field timing delay.
(5)RTS (Random Trigger Shutter) Pulse Control
The camera starts light-exposure at the TRIG signal falling-edge timing. The
exposure-time is determined by pulse length. Be sure to set the pulse interval longer
than 1H (approximately 103μs). The TRIG interval should be set longer than 2V
(approximately 133ms).
