Abstract
A camera for detecting the line-of-sight of a user includes a photographing controller for performing a continuous shot operation in which a photographing operation is repeated continuously while a release button is pressed, a line-of-sight detector for detecting the position of the user's line-of-sight, a line-of-sight detection controller for operating the line-of-sight detector for every photographing operation, a focus detector for performing a focus detecting operation based on the position of the line-of-sight detected by the line-of-sight detector, a determinator for determining whether the result of focus detection by the focus detector is appropriate, and a focus detection controller for operating the focus detector without operating the line-of-sight detector if the determinator determines that the result of focus detection is inappropriate.
