The digitizing of an analog video camera signal requires special techniques to accurately sample the signal. Careful attention must be paid to both amplitude and timing considerations. Specifications exist which define amplitude and timing parame-ters of so called "standard" cameras. Recent advances in CCD technology have lead to the development of high resolution line scan and area cameras. Unfortunately these cameras do not con-form to any published standard. Hardware designed to digitize these "non-standard" cameras must have a flexible architecture to allow for each cameras' particular interface requirements. |
