Abstract
A camera having a sight line detecting device is provided with an illumination unit for detecting the corneal reflected image of the eye of the photographer, and an illumination unit equipped with plural light sources positioned around an eyepiece lens, for detecting the position of the center of the pupil. The latter illumination unit, for detecting the position of the center of the pupil, is so controlled that a light source positioned below or at the side of the eye of the photographer is turned on regardless of the change in the camera attitude, whereby the illuminating light is not intercepted by the eyelid or eyelashes and the position of the pupil center can be precisely detected.
