If you work with a Video Camera VC45, you will find all neces-
sary information in Chapter 1.
Chapter 2 includes additional information when working with a
Video Module VM45 (= VC45 without housing).

1. Video Camera VC45

1.1 Features of the Camera

The video camera VC45 is a high performance monochrome
camera, based on a solid state image sensor. The high quality
"lens-on-chip" CCD, combined with an advanced electronics, in-
creases sensitivity of the VC45 substantially, compared with
high standard video cameras. An absolute black level is
achieved via special darkened reference pixels, yielding a per-
fect linear relation between light input and output signal. A great
number of additional features makes the VC45 suitable for
nearly every application.

Video Standard

The VC45 is easy to use. The analog video signal is a CCIR,
respect. a RS170 standard signal and compatible to the whole
video equipment on the market.
With a potentiometer at the rear panel of the camera the gain
can be set externally.

Shutter Control

An integrated shutter control allows exposure times from 100µs
to 20ms (CCIR) respect. 16.7ms (RS170). It can be set by DIP
switches, parallel or serial input.

Long Exposure

A long exposure time can be generated up to 20s by an external
or serial input. When using the external input a special power
down mode prevents the CCD from additional dark current.
There are two integration modes possible: FRAME interlaced
and FIELD interlaced.

The sensor of the VC45 is absolutely insensitive against over-
exposure, i. e. too much light cannot damage the CCD sensor.
