ABSTRACT:
A color image processing apparatus is rendered capable, in case of output of a color image, displayed for example on a color display, by an output device such as a hard copying device, of judging the color reproduction range of each output device with a limited memory capacity, by defining the color reproduction range of each output device by the interior of a hexahedron on a uniform color space (L*, a*, b*) and judging whether the input image signal Q is present inside the hexahedron by the product of the input image signal with an internal point P with respect to each plane (i) constituting the hexahedron.
