According to this invention, an image binarized by a pseudo halftone binarization processing method is forcibly encoded by an MH encoding method, and a binary image which is not binarized by the pseudo halftone binarization processing method is preferentially encoded by an MR encoding method, so that a high compression ratio can be realized. When this method is applied to a facsimile apparatus, a communication time and a communication charge can be saved.
