Claim:
1. An individual discrimination device comprising: a storage that stores an image obtained by imaging a region of at least part of a body of a user playing a video game; a vital sign signal detector that detects a signal sequence, of a detected vital sign that cyclically varies, from a plurality of imaged regions of the body of the user by using captured images of a predetermined number of frames stored in the storage; a sensor input section that receives input of a signal sequence of a sensed vital sign that cyclically varies from at least one of a sensor mounted in a controller operated by the user and a wearable sensor worn by the user; a correlation calculator that obtains a correlation between the signal sequences of the detected vital sign detected from the imaged regions of the body and obtains a correlation between the signal sequence of the sensed vital sign obtained by the sensor input section and at least one of the signal sequences of the detected vital sign detected from the imaged regions of the body; an identity determining section that determines, based on the correlation between the signal sequences of the detected vital sign detected from the imaged regions of the body, that the imaged regions of the body belong to a same user and that determines, based on the correlation between the signal sequence of the sensed vital sign obtained by the sensor input section and at least one of the signal sequences of the detected vital sign detected from the imaged regions of the body, that the imaged regions of the body belong to at least one of the operator of the controller and the wearer of the sensor; and an individual information management section that feeds back to a progression of the game at least one characteristic of the user, the characteristic being based on the detected signal sequence.
