Abstract:
An image processing apparatus comprising:a linear processor array which includes a plurality of linearly coupled processing elements;a plurality of local memories each taking a form of one-dimensional pixel data memories, said local memories being respectively assigned to said plurality of processing elements, said plurality of local memories being arranged so as to store in combination a two-dimensional pixel image to be processed;a plurality of buffers respectively assigned to said plurality of processing elements, each of said buffers storing pixel location information of at least one center pixel from which a unique pixel value is to be propagated if said center pixel exists on a corresponding local memory; anda plurality of register units respectively assigned to said plurality of processing elements, each register being accessed by adjoining processing elements and having first to third memory fields, said first memory field receiving said at least one center pixel from the associated buffer, said second memory field storing the unique pixel value, and said third memory field corresponding to pixel positions which surround the center pixel and storing information indicative of which directions the unique pixel value should be propagated.
