Abstract

PURPOSE:To reduce the quantity of data to be stored in order to improve the efficiency of a memory, and to facilitate the restoring of original image data by dividing binary image data obtained by raster-scanning an original into equal data arrayed in the scanning line direction. CONSTITUTION:The binary image data stored in an image memory 1 is divided into equal parts in the blocks arrayed in the scanning line direction by means of shift registers 2 and comparison registers 3. Such block data on a scanning line that includes picture element data in '1' is extracted in the unit of block by means of a flag register 4, a counter 5, and an address register 6, to form compressed image data. This compressed image data, the address of block data, and a block data number are stored in a compression memory 8. To restore the data, the content in the memory 8 is read out, and stored in a reproduction image memory 1, and thus the purpose is fulfilled.
