Abstract

Abstract A motion vector detector includes a motion vector computing circuit for achieving a computation of a motion vector associated with an input image signal, an integrator circuit for integrating the motion vector, a coring value decision circuit for deciding a coring value based on an output from the integrator circuit, and a coring circuit of which a coring value is controlled by an output from the coring decision circuit and which accomplishes a coring operation on an output from the motion vector computing circuit.
