Camera having visual axis detecting apparatus |
摘要 |
A camera having a line of sight detecting apparatus to detect a line of sight of an eyeball of an observer comprises: a lens device having a movable lens; a detector to detect a moving state of the movable lens in the lens device; and a controller for making the line of sight detecting operation by the visual axis detecting apparatus different from that in the case where the movable lens is not moved when it is detected by the detector that the movable lens has been moved. When a focusing lens as a movable lens is being driven, the controller stops the line of sight detecting operation by the visual axis detecting apparatus or doesn't use the line of sight detection information for the camera control.
