  • Patent number: 5565948
    Abstract: In a camera according to the present invention, a parallax correction indicator for normal-size photography and a parallax correction indicator for panorama-size photography, which are formed on an image formation plane of a finder optical system, are separately displayed in a finder image display screen set in N photographing mode and in a finder image display screen set in P photographing mode. Therefore, using the camera or the present invention, the finder display will not be complicated but be easy to see during N size photography and panorama-size photography alike. This reduces occurrence of a photographic error.

  • Patent number: 4728979
    Abstract: Apparatus for exposure control/focus adjustment for a camera comprises an exposure controlling mechanism, a focus adjusting mechanism and a source of rotary drive. The drive from the source is transmitted through a differential gearing to the exposure controlling mechanism and the focus adjusting mechanism. The differential gearing is operated such that the transmission of the drive to either one of the exposure controlling mechanism and the focus adjusting mechanism is blocked while allowing the other mechanism to be driven.
