MOTION VECTOR DETECTION DEVICE AND MOVING PICTURE CAMERA

摘要

A motion vector detection device that detects a motion vector of an object block in an object frame with reference to a reference frame, including: a reference frame storing unit that stores a reference frame consisting of a predetermined number of reference blocks; an object block storing unit that stores an object block included in an object frame; a reference block storing unit that includes a detection area which stores reference blocks including a reference block corresponding to the object block, and a preparatory area; a writing unit that reads a reference block that is not stored in the detection area among reference blocks including a reference block corresponding to a succeeding object block, and writes the read reference block into the preparatory area; and a detection unit that detects the motion vector with reference to the reference block.
