Abstract:
According to one embodiment, a color correction apparatus includes an input portion, a storing portion and a correction portion. The input portion inputs color image signals which correspond to recording color material amounts. The storing portion stores a standard color reproduction parameter for calculating a standard color reproduction chromaticity and reference chromaticity deviation amounts at a plurality of reference color points in recording color material amount coordinate space. The correction portion estimates chromaticity deviation amounts of the input color image signals on the basis of the reference chromaticity deviation amount, calculates a standard chromaticity which corresponds to the input color image signals on the basis of the standard color reproduction parameter and corrects the input color image signals on the basis of the estimated chromaticity deviation amounts and the standard chromaticity.
