<P>PROBLEM TO BE SOLVED: To measure a motion vector with high accuracy by using low computational complexity. <P>SOLUTION: A motion vector distribution calculation unit 41 calculates a motion vector distribution in a motion vector detection space defined by the predetermined number of pixels by calculating, for a target pixel to be subjected to motion vector measurement on a target frame, a score representing a correlation between the target pixel and a corresponding pixel, which corresponds to the target pixel, of a past frame while shifting the past frame to the target frame by predetermined pixels. A motion vector detection unit 43 detects a motion vector in the target pixel based on differences between a score for the motion vector distribution in the central position of the motion vector detection space and scores in positions other than the central position. An error measurement determiner 44 determines whether the motion vector is erroneously measured, based on the motion vector distribution. <P>COPYRIGHT: (C)2011,JPO&INPIT |
