ABSTRACT:
A movement vector detecting apparatus comprising: a movement vector detecting circuit for dividing an input image into a plurality of blocks and for detecting a movement vector every block; and a movement vector calculating circuit for extracting areas which perform the same movement from the movement vectors from the movement vector detecting circuit and for calculating movement vector values in such areas by executing a weight averaging process according to position information which occupies in the area of each of the blocks. A video camera having such a movement vector detecting apparatus is provided.
