Abstract:
1. An image processing apparatus comprising: a luminance correction unit configured to correct a luminance of a target lattice point in a lookup table and a luminance of a color space boundary in a hue of the target lattice point; a determination unit configured to determine the amount of a saturation emphasis such that the amount of the saturation emphasis becomes smaller as the luminance corrected by the luminance correction unit becomes larger, based on the luminance of the target lattice point corrected by the luminance correction unit and the luminance of the color space boundary corrected by the luminance correction unit; a saturation correction unit configured to correct a saturation of the target lattice point corrected by the luminance correction unit using the amount of the saturation emphasis determined by the determination unit; and a generating unit configured to generate a correction characteristic for correcting a luminance and a saturation using the luminance and the saturation of the target lattice point corrected by the saturation correction unit.
