ABSTRACT:
A visual line detection camera includes a detector to detect the visual line position of a photographer, an area determination device to determine the fixation area using an equation containing compensation terms unique to the photographer in conjunction with the results of detection accomplished by the detector, a display to display the area corresponding to the fixation area obtained by the area determination device, a fixation area selector enabling the fixation area to be altered by external operation, and a compensating factor adjustment device to alter the compensation terms in the equation when the area determined by the equation and the fixation area after alteration are different as a result of alteration by the fixation area selector. This structure enables the camera to adapt to different photographers in accordance with different photographer physical attributes, providing a visual line detection camera with a high degree of reliability.
