Chip Set for Real-Time Video Signal Processing.

Two LSIs for real-time video signal processing have been developed; One a videosignal processing LSI (called the Picot) which can process dynamic images (time-varying images) at video rate (14.3MHz); and the other a network LSI (called the Picot-net) which connects a number of Picots and makes possible multi-processing. The Picot and the Picot-net have an architecture suitable for image signal processing. They are convenient for multiprocessor systems, and efficient processing can be achieved in proportion to the number of Picots. These LSIs make possible image-signal processing, including convolution, gray level transformation, geometrical transformation. noise reduction, edge detection, and histogramming. They can thus be applied to medical imaging, robot vision, video CODEC, broadcasting, and a variety of other fields.
