ABSTRACT:
For a pixel of interest whose motion vector is not acquired in processing in the subsequent stage, motion vectors found for peripheral pixels around the pixel of interest in the processing in the subsequent stage, and evaluated values which represent the reliabilities of compensating candidate vectors, each consisting of a zero vector or the like, are calculated. The calculated evaluated values are compared, and a compensating candidate vector determined to have the highest probability is selectively acquired as the motion vector of the pixel of interest. The present invention is applicable to a signal processing apparatus for performing frame frequency conversion from a 24P signal to a 60P signal.
