ABSTRACT:
A color image processing apparatus in which the background color of an original image to be read is determined by reading the color of a designated position on the original image, by selecting data on one of a plurality of colors previously stored in memory, or by automatically performing background color detection while reading the original image. When outputting the read original image, any of the individual read pixels of the original image coincident with the background color is output as a white pixel.
