PURPOSE:To accurately display a proper exposure value on any photographic condition by selecting proper exposure data under previously stored season, time, and weather condition, and comparing it with the actual quantity of incident light and displaying an excessive/deficient state. CONSTITUTION:Dials 8-10 are rotated and set to a scale according to the season, time, and weather in photography, exposure which meets those requirements is computed by the minicomputer in a camera, and a light quantity width within a + or -15% permissible range is set by the minicomputer. The quantity of light entering the camera 1 through a lens 2 is measured and the both are compared with each other to display an excessive/deficient sign. A photographer looks at the sign and adjusts the stop 30 and shutter speed to take a picture. Thus, anybody can take a picture easily with proper exposure.
