A motion vector sensor includes a motion vector sense section (11) in which an input signal of an image plane is subdivided into a plurality of sense domains so as to compute a motion vector of an image in each of said domains, a motion vector decision section (12, 20) for judging validity of the motion vector in each domain so as to decide a motion vector of an entire image plane, a vector reliability density decision section (21) for producing a coefficient which is a function of a density with respect to time of a signal proportional to the number of the domains judged to be valid, and a control section (22) for controlling a magnitude of the motion vector of the entire image plane base don an output from said vector reliability density decision section. |
