摘要：An object of the present invention is to make it possible to detect an area in

which mixture occurs. An object extracting unit extracts a foreground object from aninput image to generate an area-specified object which is formed of a foreground imageobject and a value indicating that the object belongs to a background area. A motioncompensator compensates for the motion of the area-specified object based on thesupplied motion vector and positional information thereof. A subtracting unit subtractsthe pixel value of a pixel belonging to a foreground area of the area-specified object inframe #n−1 supplied from frame memory from the pixel value of a pixel belonging to aforeground area of the area-specified object in frame #n supplied from the objectextracting unit , in which the pixels are at the corresponding position, so as to obtain aframe difference between the pixels belonging to the foreground area. A threshold-value processor detects a mixed area based on the difference. The present invention isapplicable to a signal processing apparatus for processing an image.
