Abstract:
A storage memory for images comprises:a first memoryfor separating an image of M by N pixels into a plurality of blocks, generating H pieces of sets making coded notation of the mutually different m by n kinds of colors into each set component, and memorizing the H pieces of sets,a second indexfor having a first index identifying one of the above set, and identifying each set component of the set identified by the first index,a second memoryfor combining the first and second index into a second set, the second set comprising (M by N)/(m by n),an order of m by n pieces of the second set components equivalent to the second index of the second set comprising a set of (M+N)/(m+n) pieces of sets memorized corresponding to the order of pixels in a raster scanning in the block, anda controllerfor connecting to the first and second memories, identifying the coded notation of each color in each pixel of M by N pieces by data obtained from the both memories,outputting an image data of M by N pieces of pixels by the predetermined color information by its coded notation.
