ABSTRACT:
An image storage memory apparatus comprises a first memory for 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 H pieces of sets without a set of the above selected set component among the H pieces of sets in the other set component, a second index for 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 memory for 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, and a controller for 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, and outputting an image data of M by N pieces of pixels by the predetermined color information by its coded notation. The block address Memory is consisted of a region storing the number of the palette package line and a region storing compression or non-compression of the data stored in the palette package Memory. The number of the palette package index is stored in the block address Memory, and thus to identify a top address of the palette Memory required for the reproduction of the intended image. The desired pixel color is supposed to be selected by the processor, that is, the random access can be made.
