Abstract

Abstract A binary image multiplexing apparatus of the present invention includes a plurality of storage areas and divides a binary image signal corresponding to a binary image into a plurality of blocks respectively corresponding to the plurality of storage areas, to store the divided blocks in the storage areas. The binary image signal corresponding to at least one of the storage areas is selectively read out and is superimposed on an input image signal corresponding to the input image, so that the binary image signal can be superimposed on the input image signal, without overlapping, by means of a simple structure.
