A color image data processing device in which the color for a target picture element is corrected in accordance with the combination of colors obtained for peripheral picture elements. The peripheral picture elements are arranged around the target picture element in a predetermined relationship. A memory outputs a signal which represents a color for the target picture elements with the signal being determined by the combination of colors obtained for the peripheral picture elements. A logic circuit receives the signal from the memory and logically combines the signal with a second signal obtained from the target picture element which represents a color for the target picture element. The logic circuit then outputs a corrected color signal determined by the logical operations on its two input signals. In the preferred embodiment, the memory output signal can override the detected color for the target picture element when the detected color is red but cannot override a detected black color for the target picture element, thereby allowing correction of red ghosts of black picture elements.
