ABSTRACT:
A camera in-finder display device for displaying a selected one of a plurality of areas within a viewfinder regardless of the brightness of the subject or the ambient temperature includes light-emitting display elements and light-darkening display elements. The light-emitting display elements display the selected area by illumination and are driven by a light-emitting display circuit. The light-darkening display elements display the selected area by reducing the amount of light that is guided through said viewfinder and are driven by a light-darkening display driving circuit. A control device for controlling the camera is connected to both of the driving circuits.
