[57] ABSTRACT
An apparatus for parallelly processing image data from a local image data source, in which m rows x n columns of image data are processed by simultaneously processing n image data for each of the m rows (m and n being integers). The apparatus includes a member for serially receiving image data, a memory section having processing parameter data stored therein, a plurality of juxtaposed processor stages coupled to the memory section and arranged to be simultaneously supplied with sequentially shifted image data to thereby simultaneously produce processing results from the supplied image data and the processing parameter data, and an output section for receiving the outputs of the processor stages and delivering a processed output. The processing apparatus is suitable to be implemented in an IC form.
