Disclosed is a color filtering function useful for image processing. A first APA buffer is used for color designation, and a second APA buffer is for storing the color image. The color image in the second APA is compared with the color designated in the first APA using a color compare circuit in a color filter. When the color of the image corresponds with the designated color, the image can pass through the filter with the corresponding color.
