INTERCHANGEABLE CCD CAMERA WITH INTEGRAL BLEMISH COMPENSATION

摘要

A CCD-type video camera (2) is provided with an electronically programmable non-volatile memory (42) which stores the location of imperfect pixel ("blemish") that can be accessed by a blemish compensator located remotely from the camera (2) in a separate camera control unit (4). This arrangement allows different CCD-type video cameras to be interchangeable, regardless of their CCD blemish content, with different camera control units containing blemish correction circuitry (22).
