The processing chain begins with the light that is reflected from the
object. This light shines through the lens and hits the CCD.
The analog picture signal is sent to an A/D converter. The converter
gives the „raw“ digital representation of the picture formed by the
reflected light rays.
This picture now has to be prepared by a video signal processor
(VSP).
A control unit (CTR) establishes communication between the
processing units and the IEEE 1394 Bus interface and also makes the
parameter settings described in the following sections.
