Abstract
An object of the present invention is to make it possible to detect the mixture state of an image. An area specifying unit 103 specifies, in correspondence with image data, a mixed area in which foreground object components forming a foreground object and background object components forming a background object are mixed and a non-mixed area formed of a foreground area consisting of only the foreground object components and a background area consisting of only the background object components. A mixture-ratio calculator 104 estimates, based on the ratio of the width of the mixed area in a predetermined direction with respect to the moving direction of the foreground object, the width of the mixed area being specified by the area information, to the distance from the position of a designated pixel to the edge of the mixed area in the predetermined direction, the mixture ratio indicating the ratio of the foreground object components and the background object components of the designated pixel. The present invention is applicable to an image processing apparatus.
