Abstract
The present invention aims to recognize the mixture state of images. An area specifying unit 103 specifies a mixed area in which foreground object components which form a foreground object and background object components which form a background object are mixed. An estimated-mixture-ratio calculator 104 detects, in correspondence with the image data, the mixture ratio indicating the ratio of the mixture of the foreground object components to the mixture of the background object components in the mixed area in which the foreground object components and the background object components are mixed. At least one of the area specifying unit 103 and the estimated-mixture-ratio calculator 104 performs image processing on the basis of a plurality of types of components. The present invention can be applied to an image processing apparatus.
