ABSTRACT:
A display system for a camera that includes both a segment display portion and a dot matrix display portion. The two different display systems are driven by different duty ratios for assuring clearer presentation and quicker recognition by the photographer. The disclosure also includes an energy-saving control system for such a combination display system where the more energy-consuming dot matrix portion is stopped operating while the less energy-consuming segment portion remains operation after a predetermined time since the last operation of any switch of the camera. The disclosure further includes an elaborate analog display that clearly shows exposure parameters of the camera.
