Abstract
An image motion vector sensor is provided which includes a motion vector sense section 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 the domains, a motion vector decision section 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 for producing a coefficient which is a function of the density with respect to time of a signal proportional to the number of the domains judged to be valid, and a control section for controlling a magnitude of the motion vector of the entire image plane based on an output from the vector reliability density decision section.
