ABSTRACT:
A color signal correction apparatus, for suppressing variation of a chromaticity point of achromatic color in a display apparatus, equipped with independent luminescent characteristic correction units respectively for each color for correcting a luminescent characteristic of luminance of respective RGB colors, an offset value for use in chromaticity correction, for suppressing variation of a chromaticity point of a simple color and a white color, which is defined in accordance with a luminance level is selected or generated based on one or two color data selected from respective RGB colors inputted into the correction unit, and the value is added to one color data selected from remaining one or two colors, and inputted into that color's correction unit, and thereby, it becomes possible to produce a color signal for suppressing variation of the chromaticity point, and to suppress variation of a chromaticity point of a simple color and an achromatic color.
