Abstract
An image processing apparatus that makes it possible to reproduce image information without omission and improves the compression efficiency of image data. Character pixels are detected from an image generated by reading an original using a scanner. Color information for use in compressing image data is determined. A color-converted image image is generated on which colors of the detected character pixels are corrected based on the color information, without changing colors of pixels other than the colors of the detected character pixels. The color-converted image is divided into images of respective colors of the color information. Compressed data of binary images is generated from the divided images of the respective colors.
