Abstract:
An image processing apparatus in which image data is divided into Mb.times.Nb blocks arranged in Mb rows and Nb columns, each block having p.times.p pixels, and fixed length code data compression is performed on each said block (where p, Mb and Nb are positive integers), comprising:control means for controlling image compression by said image processing apparatus;data compression means receiving first data of p pixels corresponding to one row of said block out of said image data successively applied externally line by line, and second data applied under the control of said control means, for performing fixed length code data compression on data obtained by integrating the first data with the second data;storing means receiving an output from said data compression means for storing, in accordance with which of said blocks the compressed data belongs to, the output in one of memory regions allotted corresponding to respective ones of said Mb.times.Nb blocks; anddata decompression means controlled by said control means for receiving, in accordance with which of said blocks the first data to be input to said data compression means belongs to, the data which has been subjected to fixed length code data compression and stored in a corresponding one of said memory regions of said storing means, and for performing fixed length code data decompression and applying the result as said second data to said data compression means.
