Signal Processing (Camera Control Unit)
The three signals, RGB, derived from the camera sensors require electronic processing before they are coded to provide the camera output signal. Modern cameras house all the processing electronics and the coder in the camera head, with some provision for remote control of important facilities. Older cameras carried out this signal processing in a separate camera control unit (CCU).
Control features
Typically the processing, mentioned in the manufacturer’s literature, includes:
