An image area discriminating system for an image processing apparatus which discriminates between a character area and a halftone area on an original document containing the character and halftone areas, selects parameters for each discriminated area, and adjusts and generates image data. The image area discriminating system comprises: a block color discriminating unit for grouping pixels into blocks and determining block colors on the basis of the formed pixel blocks; a determining unit for detecting the run lengths of block colors other than white, for comparing the detected run lengths with a predetermined threshold value, and for determining whether the document area is the character area or the halftone area; and an area signal output unit for outputting a signal to select an image area signal on the basis of an output signal outputted from the determining unit.
An image area discriminating system for an image processing apparatus for discriminating between a character area and a halftone area on an original document containing characters and halftone areas, for selecting parameters for each discriminated area, and for adjusting and generating image data, said image area discriminating system comprising:
An image area discriminating system for an image processing apparatus for discriminating between a character original document and a halftone original document, and for executing full-color output processing for a color original document and black-toner developing output processing for a black and white original document during a main scan, said image area discriminating system comprising:
