ABSTRACT:
An object of the present invention is to data compress a binary image which includes a pseudo expressed halftone image effectively. To attain this object, an image processing apparatus of the present invention comprises region division means for dividing an input binary image data into a region of a pseudo expressed halftone image portion and a region of another portion, first encoding means for generating multi-value image data from binary image data of said pseudo expressed halftone image portion and encoding the obtained multi-value image data, second encoding means for encoding at least a part of the binary image data from a portion other than the pseudo expressed halftone image portion.
