Title:
MOTION SENSOR, METHOD FOR DETECTING OBJECT ACTION, AND GAME DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/002803
Kind Code:
A1
Abstract:
A motion sensor has: an object-region extraction unit (51) for extracting the object region projected by a detection object based on a first and a second image projected by the detection object; a reference-point-specifying unit (52) for determining a reference point showing the boundary between a moving portion of a detection object moving by performing a predetermined action in the first and the second images, and a fixed portion of the detection object which moves less than the moving portion even when the predetermined action is performed; a movable-portion-position-detecting unit (53) for determining the position of the moving portion within a region closer to the movable-portion than the reference point in the first and the second image; and an assessment unit (54) for assessing whether the predetermined action has been performed when the difference between the position of the moving portion in the first image and the position of the moving portion in the second image is equivalent to the movement of the detection object in the predetermined action.
