摘要： A high speed, multi-function and expandable image processing LSI (image signal processor) for realizing density image processing technique has been developed. An architecture of the image signal processor (ISP) which can process a density image having 256 tones at a video rate (256 x 256 image, 6MHz, non-interlace), allows expansion of a partial operation area (kernel) and can carry out various partial neighbourhood operation, is disclosed. The image signal processor (ISP) is a partial parallel type image processing LSI which carries out a parallel operation by using the same number of processor elements (PE's) as that of input pixel data used to produce one output pixel data.
