ABSTRACT:
A digital color converting apparatus applicable to a color copier and others for converting only a desired color included in a color image into another desired color. One of a plurality of input image signals which has the highest level is identified to determine a color to be rendered by the instantaneous signals and, then, whether the result of the identification and a color specified are coincident is determined. Hence, color conversion is effected only in those regions in which the image is regarded as being of the color specified. For color conversion, the input image signal associated with an original color to be changed is applied to an output terminal which is assigned to an alternative color while, at the same time, the input image signal associated with the alternative color is applied to an output terminal which is assigned to the original color, i.e., signals individually associated with the original and alternative colors are replaced with each other.
