ABSTRACT:
An LSI parallel image processor in which line buffers and data-flow switching circuits each requiring a larger amount of hardware in the prior art are incorporated into an LSI circuit, the image data delayed by the line buffers is output from an image data output port, shift registers each having a variable number of steps for preserving local image regions are intermittently shifted-in in accordance with applied clocks, and the contents of the shift registers are sequentially read out.
