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.
