Abstract
An apparatus for and a method of adjusting a primary color component of an image and a computer-readable recording medium for storing a computer program for controlling the apparatus. The apparatus includes: a weight determiner which determines a weight corresponding to a hue difference between a hue of each of plural object hue components and a hue of adjustment primary color; and a component adjuster which adjusts at least one of object hue and saturation components using at least one of saturation and hue adjustment amounts of the adjustment primary color and the weight. The object hue and saturation components are components of 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.
