Zusammenfassung:PROBLEM TO BE SOLVED: To generate OCR image data having a drop-out color and high resolution by an image processing method for generating image data for an OCR from color image data. SOLUTION: The image data (63) of a drop-out color are extracted from color image data, luminance data (66) of high resolution are filtered by the image data (59) to remove a drop-out color part from the luminance data (66). Thus luminance data (68) of high resolution from which the drop-out color is removed can be generated as image data for the OCR. Consequently highly accurate character recognition can be carried out.
