ABSTRACT:
An automatic exposure control camera, with a plurality of selectable control modes, has a display device that normally display an exposure value determined by the control mode and by operating conditions of the automatic exposure control. The user may cause the display device to display a different exposure value, which again depends upon the control mode and the operating conditions of the automatic exposure control. A further display device displays the selected mode and also indicates, as by the blinking of an indicator element, when certain limits of exposure time value or aperture value have been reached (with appropriate modification of the exposure control operation). In one control mode, the automatic exposure control is reprogrammed in association with the selection of shutter speeds.
