ABSTRACT:
A binary image signal is subdivided into blocks binary a size of "n", and coordinates of changing points of the binary image signal are detected within each of these subdivided blocks. A changing-point table is employed which stores therein a set of changing-point coordinates for each of all bit patterns produceable by the block having the size of "n". Also, an index table is provided which stores therein an initial address of the changing-point table into which the changing-point coordinate set corresponding to each bit pattern of these produceable bit patterns has been stored. A serial/parallel converter comments the binary image signal into the blocks having the size of "n". This block with the size of "n" is supplied to the index table, and an initial address corresponding to the inputted block is outputted from the index table. Based on this initial address, an address generating circuit reads a changing-point coordinate within the block from the changing-point table. The parallel/serial converter converts this read changing-point coordinate into a changing-point within a horizontal scanning line.
