ABSTRACT:
A subject color and a non-subject color of a mask is specified, and a first color vector representing the subject color and a second color vector representing the non-subject color are determined. A third color vector is set to be linearly independent of the first and second color vectors. First through third coefficients are then determined for the first through third color vectors. Bit map data representing the distribution of the first coefficient is binarized to give binary mask data representing a mask. A mask area and a non-mask area are distinguishably displayed in the color image. Accordingly, the present invention will produce a mask area whose color is close to the subject color while excluding the non-subject color.
