Abstract
A motion vector detecting apparatus detects only motion vectors generated by fluctuation of a video camera even if an object subject to imaging moves within a picture. This detecting apparatus comprises a distance information detecting circuit for detecting distance information from objects corresponding to detection windows obtained by dividing a picture into a plurality of blocks to an imaging device, an information detecting circuit for detecting motion information substantially corresponding to the plurality of divided detection windows, and a calculation circuit for determining weighting coefficients on the basis of at least the distance information and for determining motion vectors on the basis of the weighting information and the motion information.
