ABSTRACT:
This camera includes a viewfinder and a device (4) for detecting the visual line of a photographer looking through the viewfinder, an operation member (1), (8) such as a release button which is operated by the photographer to take a photograph, a means (2) for inputting calibration information, and a means for performing photography (5), (6), (7). The calibration information input means (2) operates in response to the operation of the operation member (1), (8), and inputs and stores calibration information when the photographer fixates on a target mark (3, b) visible within the viewfinder, based upon the visual line detected at that time by the visual line detection means (4). The object intended by the photographer to be photographed is detected and photographs it, based upon the visual line detected by the visual line detection means (4) and the stored calibration information.
