ABSTRACT:
A camera control system in which one or more slave cameras are made to follow the motional and/or optical (zoom) adjustments of a master camera.
Each motional or optical parameter is represented by a train of pulses related to the master camera, which pulses are digitally processed.
Corrections to a parameter to insure accurate synchronous tracking are made by changing the effective number of pulses in a train of pulses according to a predetermined correction program. The corrected pulse trains power each slave camera by energizing pulse-responsive actuators on the slave cameras.
