Area-Scan Analog Camera

The following diagram depicts the Camera Active Window of an analog area-scan camera used in analog or master synchronization mode. For the sake of simplicity, a progressive video format is represented. The camera timing parameter structure supports the interlaced format as well.

The diagram includes the possible use of horizontal and vertical drive pulses sent to the camera (genlocking the camera).
