Abstract
An image processing apparatus includes a process mode setting unit which sets a process condition for image reading such as edge emphasis degree, selection of binarization or pseudo-halftone processing, and a threshold level of a binarizer/pseudo-halftone processor. In the processing of an original including an OCR sheet as the first sheet, the process mode setting unit sets a process condition corresponding to an OCR reading for the OCR sheet, and for the next sheet, the unit changes the process condition appropriate to a reading mode designated by a user. Thus, the apparatus realizes image reading having excellent reproductivity, while preventing erroneous recognition during OCR reading.
