Abstract
A camera capable of utilizing a visual line of a photographer for a photographic operation is provided. The camera includes a visual-line detecting part for detecting a visual line (fixation point) of the photographer and a correcting part for correcting a deviation between the fixation point detected by the visual-line detecting part and an actual fixation point of the photographer's eye. The correcting part operates in association with a starting operation of the camera.
