Detection apparatus for detecting movement of object, detection method and storage medium

Abstract

The average value calculation section acquires luminance information and color information, from captured images continuously captured in frame as a unit by an image capture unit. The detection method determination section determines either one or both among the luminance information and color information to use in order to detect movement of the predetermined object, based on the luminance information and color information acquired. The motion detection section detects movement of the predetermined object using either one or both among the luminance information and color information based on the result determined.
