Abstract
A camera includes a photo-taking lens, an automatic focus adjusting device for effecting the automatic focus adjustment of the photo-taking lens, an eye-gaze detecting device for detecting the photographer's eye-gaze position in a finder field corresponding to a photographing picture plane, and producing an eye-gaze detection signal corresponding to the eye-gaze position, a focus adjustment signal producing device for outputting a plurality of focus adjustment signals corresponding to a plurality of detection areas in the photographing picture plane, and a control signal producing device for producing a control signal for controlling the automatic focus adjusting means, on the basis of the eye-gaze detection signal and the focus adjustment signals. The control signal producing device produces the control signal on the basis of the plurality of focus adjustment signals corresponding to the plurality of detection areas when the eye-gaze position indicated by the eye-gaze detection signal is at a position between the plurality of detection areas.
