ABSTRACT:
A camera which performs visual line detection, and which assigns priority to photography when a release operation is performed during calibration information input for visual line detection. The camera includes an input unit to input into the camera calibration information relating to an eye of a photographer. The calibration information is automatically input when the photographer contacts an eyepiece of a viewfinder. A calculation unit calculates the visual line of the photographer, based upon the input calibration information and the state of the eye of the photographer looking through the viewfinder. A setting unit sets photographic conditions based upon the calculated visual line. When a release operation is performed during the action of calibration information input, a priority action execution unit suspends the input of calibration information, and the priority action execution unit actuates a photographic unit such that photography may be performed. Further, previously input calibration information is overwritten with the latest data such that calibration information for the present photographer is automatically input.
