In a color correction apparatus for correcting the color image data, a color
adjustment
amount for canceling a difference between the optimum value (Rt, Gt, Bt) predetermined
for the fixed-color pixel and the result of the summing-up is obtained. Therefore,
the color adjustment amount is corrected on the basis of the fixed elemental color
elements of the pixel, and the color image data is color-corrected on the basis
of the corrected color adjustment amount. Since a computing equation for adjustment
operation is simple, the processing time can be shortened. Further, since the color
adjustment amount is corrected on the basis of the fixed memory color element of
each pixel, it is possible to suppress color jumping.
