<P>PROBLEM TO BE SOLVED: To provide an image photographing device with a visualline detection function, which can protect the copyright of a photographed image by surely recording iris information of a photographer without affecting processing and an operational feeling at the time of photographing an object image. <P>SOLUTION: When an eyeball image acquisition sensor 113 acquires an eyeball image of the photographer, iris information is acquired at the same time during a calibration operation that is carried out before photographing to acquire and calculate a correction coefficient about an individual difference for correcting the deviation of the optical axis of an eyeball from a visual line. An iris image line of sight correction coefficient is calculated from the acquired eyeball image, and a set of the iris information and the correction coefficient is managed with the same ID number. <P>COPYRIGHT: (C)2004,JPO |
