Abstract
Obtaining an image frame picked up by a camerathrough a cable C, a CPUof a computeridentifies an eye area in the image frame and stores a template indicating the identified area as a tracking template. Moreover, the CPUidentifies an eye area in an image frame to be obtained subsequently on the basis of the tracking template, and calculates a correlation value between the template of the identified area and the tracking template. Furthermore, when the calculated correlation value is larger than a threshold stored in an HDin advance, the CPUstores the template indicating the identified area in the RAMas a tracking template, so as to update an eye area in a series of two image frames in chronological order.
