摘要

Provided is a motion detection device with which motion detection can be carried out without increasing the computation cost. This motion detection device is equipped with an image acquisition unit for acquiring a subject image, a vector derivation unit for deriving a motion-related vector from the subject image acquired by the image acquisition unit, and a motion detection unit for carrying out motion detection by tracking a vector derived by the vector derivation unit.
