During compressing an image at the compression processing section (image compressing apparatus), the color image processing apparatus detects edge of text and/or line art, generates the foreground layer represented by binary image for showing the detected edge, compresses the foreground layer with lossless compression, and compresses the background layer which is an image except the foreground layer with lossy compression. Furthermore, the color image processing apparatus sets the foreground layer color different from a color of text or line art, and provides information representing the set color into the compression file. As the set color, the color image processing apparatus utilizes the overall color representative for whole region of the image, or the text-vicinity color in the image. The edge region of the text and/or line art are represented with such the set color on the reproduced image based on the compression file.
