Abstract: PROBLEM TO BE SOLVED: To obtain correct saturation data even at the time of generating the phase shifting of R, G and B data by detecting a saturation quantity necessary for judging whether an original is a black-and-white part or not based on plural pieces of color data. SOLUTION: Read image data is decomposed to long wave length data and short wave length data to generate plural sets of color data obtained by shifting them in a main scanning direction. Then the saturation quantity of the image is detected from these plural sets of color data to change image processing contents based on this. At the preceding stage of obtaining this saturation data, the phase shifting of R, G and B data caused by color aberration phenomenon is corrected. Phase correction circuits 1461 to 1464 correcting four kinds of color aberration states are prepared, saturation data (=maximum color-minimum color) of R, G and B data in each correcting circuit is obtained by saturation detecting circuits 1465 to 1469 and smallest data in the saturation data is selected by a selection circuit 1471 to make color-aberration-corrected saturation data.
