Image motion vector sensor for sensing image displacement amount
First Claim
1. An image motion vector sensor, comprising:
- 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 said domain;
a motion vector decision section for judging validity of the motion vector in each said domain so as to decide a motion vector for an entire image plane, said motion vector decision section counting the number of the domains which contain a motion vector judged to be valid;
a vector reliability density decision section for producing a coefficient which is a function of density with respect to time of a signal proportional to said number supplied by the motion vector decision section; and
a control section for controlling a magnitude of the motion vector for the entire image plane based on the output of said vector reliability density decision section.

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.
