  • Patent number: 5499068
    Abstract: A shake detecting section for detecting a camera shake, a prevention mode selecting section for selecting a shake prevention mode, and a print area setting portion for setting a print area in a trimming photographic operation are connected to a control section. In addition, a print area display section for displaying the print area set by the print area setting section in the finder of a camera, a focal length information storage section for storing the focal length information of a photographic lens, and a trimming mode selecting section for selecting a trimming mode are connected to the control section. When the trimming mode is selected by the trimming mode selecting section, the hand shake prevention mode is automatically selected, thereby easily preventing a deterioration in image quality due to a hand shake.

  • Patent number: 5452035
    Abstract: A Patrone and a camera using the Patrone. The Patrone comprises a film wind spool arranged in a cylindrical body, of which upper and lower ends are light-tightly sealed. The body stores film so that the film can move freely in or out of the body in such a manner that the film can rotate freely, and is wound about said spool in roll form. Locking members are arranged in the cylindrical body and can be displaced freely relative to the spool. Ends of the locking members normally project outwardly from the cylindrical body. Locked members are arranged opposed to said locking members and are formed substantially as parts of one of the cylindrical body or spool. An elastic member normally urges each of the locked members toward engagement with an associated locking member.

  • Patent number: 5430513
    Abstract: A film cartridge in which a supply spool incorporated in a cartridge body is rotated to supply a film wound on the supply spool out of the cartridge body. A film supply unit rotates the supply spool to supply the film out of the film cartridge. A first control unit controls the film supply unit such that a supply operation of the film is started in response to a closing operation of the rear cover of a camera body. A film take-up unit takes up the film supplied by the film supply unit. A second control unit controls the film take-up unit to operate the film take-up unit upon completion of the supply operation of the film performed by the film supply unit. A third control unit interrupts a take-up operation of the film performed by the film take-up unit and reoperates the film supply unit when the take-up operation of the film is impossible during the take-up operation of the film performed by the film take-up unit.

  • Patent number: 5365290
    Abstract: A camera capable of recording photographic information, according to the invention, comprises, a pressure-information detector for detecting pressure information at a location where a camera body is positioned, a magnetic recorder for recording the information detected by the pressure-information detector onto a magnetic memory section provided on a film, as environmental information, and a recording controller for controlling the photographic-information recorder such that the detected information and a photographic image are recorded correspondingly to each other.

  • Patent number: 4598986
    Abstract: An apparatus for exposure correction is provided for use with a camera of automatic exposure control type. An amount of exposure which is determined on the basis of an output from photometric means is shifted by a given correction value toward overexposure or underexposure in response to the operation of a manual operating member. The correction value can be varied either automatically or manually. The correction value can be changed by automatically reading information given on a film or a film container and representing a film latitude, by manually supplying a film latitude value, or by utilizing information representing a film speed which has a correlation with a film latitude. In this manner, a photograph having an improved gradation can be obtained by effectively utilizing a film latitude.
