IMAGE PROCESSOR

摘要

An image processor which can detect an region where a plurality of objects, e.g. the image of background and the image of a moving object, are mixed. A background image generating section (121) generates a background image based on image data. A binary object image extracting section (122) detects a correlation value of each pixel of the image data of an interesting frame and the pixel of the background image at a position corresponding to each pixel of the image data of the interesting frame. A time variation detecting section (123) detects a region of the interesting frame where a plurality of objects in real world are mixed based on the time variation at each pixel position of the correlation value. The invention is applicable to an image processor where difference between a signal detected by a sensor and the real world is taken into account.
