Patent ID: 7646393

Claim:
An apparatus for adjusting a primary color component of an image, comprising: a weight determiner which determines a weight based on a determined hue difference between a hue of each of plural object hue components and a hue of an adjustment primary color; and a component adjuster which adjusts at least one of the object hue components and a saturation component using at least one of a saturation adjustment amount and a hue adjustment amount of the adjustment primary color and the weight, wherein the object hue and saturation components are hue and saturation components of an input image belonging to an adjustment range, the adjustment range belongs to a region of a color space in which color interference between the adjustment primary color and a neighboring primary color occurs, the adjustment primary color corresponds to a primary color to be adjusted, and the neighboring primary color corresponds to a primary color neighboring the adjustment primary color, wherein, in the determining of the weight, a determined weight based on an absolute value of a first hue difference is determined to affect adjustment of the at least one object hue components and the saturation component more than an adjustment affect of a determined weight based on an absolute value of a second hue difference when the absolute value of the first hue difference is less than the absolute value of the second hue difference.
