PROBLEM TO BE SOLVED: To solve such a problem that when performing low resolution processing (reduction processing) for separating input image data into character image data and image data, and generating image data of lower resolution than the input image data, the color of a color image on the periphery of a character changes if a plurality of pixels are simply reduced to one pixel.SOLUTION: In the calculation when performing reduction processing for reducing a plurality of pixels of input image data to one pixel of image data, the ratio using the pixel value of a character attribute pixel is brought to 0, or the ratio using the pixel value of a character attribute pixel is made smaller than the ratio using the pixel value of an image attribute pixel, thus suppressing change in the hue of a color image on the periphery of a character. |
