Color image processing with smoothing of differential components and addition of the result to a specific color component

摘要

A color image processing apparatus includes an input unit for inputting a plurality of color component signals representing a color image, a first operation unit for obtaining differences between a specified color component signal among the plurality of color component signals and other color component signals and outputting the differential signals, a second operation unit for smoothing-processing the differential signals obtained by the first operation unit, and a third operation unit for adding the differential signals smoothing processed by the second operation unit and the specified color component signal and outputting the result as the other-color component signals.
