IMAGE PROCESSING DEVICE AND METHOD, AND IMAGER

摘要

An area where mixture is present can be detected. An object extracting unit (251) extracts a foreground object from an input image and generates an area specific object composed of the image object of the foreground and a value representing that the pixel is in the background area. A motion compensation unit (252) carries out motion compensation of the area specific object on the basis of the supplied motion vector and its position information. A subtraction unit (254) subtracts the pixel value of a pixel in the corresponding position in the foreground area of the area specific object of frame n-1 supplied from a frame memory (253) from the pixel value of a pixel in the foreground area of the area specific object of frame n supplied from the object extracting unit so as to determine the frame difference of the pixels in the foreground area.
