摘要：
A color image data processing apparatus (1) processes hue information of picture elements read out sequentially. The apparatus comprises a chromatic color detection unit (4) for detecting a chromatic color picture element series that is a consecutive succession of chromatic color picture elements in a main scanning line, a replacing unit (5) for replacing the hue value of each picture element of the chromatic color picture element series with the hue value of a picture element located approximately at the center position of the detected chromatic color picture element series. The apparatus may further include an averaged hue value switching unit for switching the replaced hue value of each of the picture elements with the average of the replaced hue values of each picture element and picture elements located in a nearby region of said each picture elements.
