  • Patent number: 5799215
    Abstract: A camera system comprises a brightness measuring circuit, a exposure line choosing circuit, an operable switch, a film driver and a film driving mode selector. The brightness measuring circuit measures brightness of a photographic scene to send a brightness value. The exposure line choosing circuit chooses one of a plurality of exposure lines in which each lines selects a combination of an aperture value and a shutter speed value at each brightness value. The film driver drives a film in either of a first mode in which the film is wound only one frame in response to the operation of the operable switch and a second mode in which the film is wound frame by frame continuously as long as the operable member is operated. The film driving mode selector selects one of the modes in accordance with the exposure line chosen by the choosing circuit.

  • Patent number: 5235379
    Abstract: A camera system comprises a selector, an operable switch, a changing circuit and an inhibiting circuit. The selector selects one of a plurality of exposure lines. The changing circuit change as combination of the aperture value and the shutter speed value determine by both the selected exposure line and a brightness value in response to the operation of the operable switch. The inhibiting circuit inhibits the operation of changing circuit when a predetermined exposure line is selected by the selector. In the camera system, a photographer may only select the exposure mode through the operable switch in accordance with his intention and purpose in photography, and then the change of the exposure combination is inhibited in a certain exposure mode.

  • Patent number: 5130737
    Abstract: A bracket photographing apparatus for a camera system using a flash light unit. In a flash bracket photographing, a series of photographs (frames) are taken with the film exposure differing between the frames, where the exposure difference is caused by a change in the light emitting amount of the flash light unit. The invention also considers the case where a flash light unit is not attached to the camera body, or is not controllable by the system (e.g., the attached flash light unit is not a controllable type).

  • Patent number: 5128700
    Abstract: In a camera capable of recording sound data corresponding to photographed frames of a film respectively, the sound data can be recorded in a first memory (e.g. a sound IC card), and data indicating correspondence between the photographed frames of a film and the sound data respectively can be recorded in a second memory (e.g. a film). Though the first memory, namely, the sound recording memory and the second memory, namely, the film are separate, the recorded sounds can accurately correspond to the photographed frames of the film respectively.In a sound playback apparatus, by attaching thereto a medium in which sound data are recorded in each area thereof and a print in each frame of which a code indicating a sound recording area is recorded, the sound playback apparatus can play back sound data corresponding to the photographed frames of the film respectively from the medium.
