Abstract: A viewpoint detection unit detects a user viewing a stereoscopic image, including a parallax image of a subject as viewed from a predetermined position defined as a reference view position, and tracks a viewpoint of the detected user. A motion parallax correction unit determines, if a speed of movement of the viewpoint becomes equal to or higher than a predetermined level, an amount of motion parallax correction for the parallax image, on the basis of an amount of movement of the viewpoint, so as to generate a stereoscopic image corrected for motion parallax, generates, if the speed of movement of the viewpoint subsequently becomes lower than a predetermined level, a stereoscopic image by changing the amount of motion parallax correction in steps until the parallax image return to parallax images as seen from the reference view position.

Abstract: A frame storage stores an image obtained by imaging a region of at least part of the body of a user. A vital sign signal detector detects a signal sequence of a vital sign that cyclically varies from plural imaged regions of the body of the user by using captured images of a predetermined number of frames stored in the frame storage. A correlation calculator obtains the correlation between the signal sequences of the vital sign detected from the respective imaged regions of the body. An identity determining section determines whether or not the respective imaged regions of the body belong to the same user based on the correlation between the signal sequences of the vital sign detected from the respective imaged regions of the body.
