PURPOSE:To allow simple constitution which uses common light emitting elements to display both exposure information and overexposure/underexposure warning by displaying the exposure information digitally and flashing the display at specific cycles in case of overexposure or underexposure. CONSTITUTION:Digital exposure information from a photometric circuit 1 is displayed on solid-state light emitting elements of a display device 3 through a gate 2. When this exposure information shows overexposure or underexposure, an AND gate 4 is opened through a warning signal generating circuit 5 and the gate 2 is turned on and off by a rectangular wave with a specific period supplied from a rectangular wave oscillator 6 through the gate 6 to flash the display of the device 3 as the warning display of the overexposure or underexposure. Therefore, the simple constitution which uses the common light emitting elements displays both exposure information and warning information corresponding to the overexposure or underexposure.
