Abstract

The main goal of this work is to provide as quickly and as easily as possible the transfer and transformation of the underlying information between a video camera acting as the source of the picture and the processor memory. For this purpose a simple special purpose camera was built for evaluation use. This is considered to be a feasibility study. Communication into the processors memory was accomplished by using transputer links. the basic idea was to generate clock signals according to the processors operation and thus be able to shift information directly into the processor memory without using an intermediate buffer. Synchronization was performed on a pixel basis in order to input the original information precisely without over- sampling. The result of this work is a faster transfer and access to usual information, with less data still containing all information available in the camera. The technical results are illustrated using a sample camera built for evaluation purposes. This camera is based on LCA control circuitry, using a transputer as a processing element. It is understood as a feasibility study.
