Abstract
An image motion vector detecting device has a part for determining correlation values in specific deviation in each detecting region of disposed plural detecting regions in a screen, a part for determining a time variation value of the correlation values, a part for determining a motion vector in each detecting region from the correlation values, a part for judging a reliability of the motion vector in each detecting region by using the correlation values and the time variation value, and a part for determining a motion vector of an entire screen by using the motion vector of each region on the basis of the judged reliability.
