PROBLEM TO BE SOLVED: To provide a motion vector detection device capable of preventing the deterioration of detection precise which is caused on the end part of a block in the block matching type motion vector detection device. SOLUTION: In the case of detecting a difference by a block correlation operation circuit 13 and generating a vector interpolation signal by a motion vector interpolation circuit 17 in accordance with the detection signal, the block size of vector detection is reduced as compared with the block size of vector interpolation. Consequently, the problem of misdetection on the end of the detection block can be improved.
