Abstract
Color information of a color image is represented by the Lab color space. A user can change hue by moving the position of a reference circle displayed on the a*b* plane in the Lab color space and change saturation by changing the size of the reference circle. The color information of the color image is changed with changes in the reference circle, allowing the user to conjecture changes in the color image visually and make color corrections easily and quickly.
