ABSTRACT:
Disclosed herein is a camera system and camera controller having a modularized design. Camera control functions within the controller are distributed among a number of modules, each module performing a component task of controlling a camera. Individual modules can perform tasks such as generating clock signals, digitizing an analog video signal, and providing multiplexed digital video output. Modules communicate with each other over a common bus sufficient to carry the signals necessary to control the camera. The system implements a RAM-based digital sequencer that provides the capability of loading bit patterns into memory and using these patterns to generate waveforms for clocking a CCD. Clock and readout sequences can be composed in a high level language, compiled and uploaded into the controller. Adjustable clamp and sample signal delays used in digitizing an analog video signal provide the capability to optimize the performance of the system in a given application.
