Motion vector detecting apparatus and image stabilizer including the same.

摘要

A motion vector detecting apparatus (50; 150) comprising: a motion vector detector (20) which divides an image of an inputted image signal into a plurality of regions so as to calculate motion vectors at the regions, respectively; a characteristics detector (11; 111) for detecting characteristics of the motion vectors or of calculation data of the motion vectors so as to detect a state in which a number of points having close correlation exist in the image; and a vector control and decision unit (12; 113) which determines, when said characteristics detector (11; 111) has detected the state, some of the motion vectors at one of the regions free from the state so as to select a motion vector of the image signal from the some of the motion vectors by neglecting the remaining motion vectors at the remaining regions in the state, and an image stabilizer (100; 200) for correcting sway of an outputted image, which includes the motion vector detecting apparatus (50; 150). <IMAGE>
