ABSTRACT:
In an image processing apparatus, comprising: image data sent from a transmission-side apparatus is received, and discrimination is performed as to whether the image data received is a character image or a halftone image segmentation processing is then performed on the reception data. When the discrimination means discrimitaes that the received image data is a character image, interpolation processing is performed on the basis of reception image data in a predetermined area, to perform segmentation processing of image data of a pixel of interest, and so the apparatus can perform segmentation processing of input data by simple control at high speed and low cost.
