Abstract:
An object extraction apparatus for a moving picture, comprising:a background region determination section which determines a first background region common to a current frame and a first reference frame, and a second background region common to the current frame and a second reference frame, the current frame containing a target object to be extracted from a moving picture signal, the first reference frame being temporally different from the current frame on the basis of a difference between the current frame and the first reference frame, the second reference frame being temporally different from the current frame on the basis of a difference between the current frame and the second reference frame, and the first background region and the second background region indicating a background in the moving picture; and an extraction section which extracts a region, in a picture on the current frame, which belongs to neither the first background region nor the second background region as an object region.
