Abstract:
1. An image compression coding apparatus comprising: an image compressor for compressing input image data and to output image compression data constituted by a plurality of subdivided data; an overflow detector for detecting that an output buffer for temporarily storing data generates an overflow or not; a subdivided data top detector connected to said image compressor and said output buffer, for serving to carry out a normal operation for exactly giving said image compression data to said output buffer and a detecting operation for detecting a top position of said subdivided data from said image compression data to give said image compression data to said output buffer from said subdivided data of which top position is detected; and control means connected such that a result of detection of said overflow detector can be recognized, for serving to cause said subdivided data top detector to execute said detecting operation when an overflow is detected by said overflow detector and to set, as a value of a register indicative of a write destination of said output buffer, an address where a top of said subdivided data a part of which cannot be written to said output buffer is written.
