Abstract
A method for extracting a three-dimensional color vector from a three-dimensional color space in which correlated features are distributed includes steps of projecting the three-dimensional color space on a two-dimensional plane, displaying the two-dimensional plane on a display screen of a display, designating a line segment on the display screen by an input device, and executing the above steps at least two times by changing the angle of projection between the three-dimensional space and the two-dimensional plane to extract the color vector.
