Abstract
A past frame at a past time has a motion vector in a block, and a reference frame at a reference time has a different block which is a motion-compensated block identical in position to a terminal point of a motion vector in the block. When a gradient method is used to detect a motion vector in the different block in the reference frame, a motion vector which is identical in magnitude and orientation to a motion vector and whose initial point is the different block in the reference frame is used as a candidate vector for initial vectors. The present invention is applicable to a signal processing apparatus for performing frame frequency conversion from a 24P signal to a 60P signal.
