ABSTRACT:
A neighbor image processing device for processing image data according to predetermined program comprises: an address generator for simultaneously generating addresses corresponding to each of a central point and a plurality of individual neighbor points of an image neighbor region; a buffer memory for simultaneously receiving data on the points, and their corresponding addresses from the address generators; a central processor coupled to the address generator and the buffer memory for comparing the neighbor point data with data on the central point of the neighbor region; an arithmetic and logic unit connected to the central processor for selectively modifying the data simultaneously for the individual points according to instructions from the central processor; a data integration unit for receiving a plurality of simultaneous outputs from the arithmetic and logic unit and generating a single output based on instructions from the program; and a decision integrator for receiving a plurality of the single outputs from the data integrator and generating a coded multivalue based on instructions from the program.
