Image processing hardware, a high-speed image processor and an intelligent image memory unit, are presented and their applications to the industrial image processing are discussed. An image processor has been realized on the basis of local parallel computation architectures, which contribute to speeding up major calculations and to reducing the hardware cost and complexity. An image memory unit has been implemented to manipulate and display the image data with a highly intelligent control, which helps man-machine interaction to be effective. Although these processors are conceptually designed for general image processing purposes, several feasibility studies have revealed that they can be utilized as com-petent simulation tools for research works on shape recognition, particle measurement, real-time signal processing, etc.
