ABSTRACT:
The present invention relates to a picture processing apparatus that allows detection of an area in which a plurality of objects, such as a background picture and a picture of a moving object, is mixed. A background picture generation unit121generates a background picture based on picture data. A binary object picture extraction unit121detects a correlation value between each pixel in picture data of a frame under consideration and a pixel in the background picture at a position corresponding to the pixel in the picture data of the frame under consideration. A temporal change detection unit123detects a mixed area in the frame under consideration, in which a plurality of real-world objects is mixed, based on a temporal change of the correlation value at each pixel position. The present invention can be applied to a picture processing apparatus that takes difference between a signal detected by a sensor and the real world into consideration.
