  • Patent number: 5721970
    Abstract: A distance measuring device for a camera uses a normal photographing mode which and a special photographing mode can be selected, and where in the special photographing mode includes a remote control photographing mode. The distance measuring device detects an object distance and judges whether the distance detection is effective or not, and a lens is driven based on a predetermined value when it is judged that the distance measurement is not effective in a normal photographing mode. In contrast, in a remote photographing mode, when it is judged that the distance measurement is not effective, the lens drive is not driven based on a predetermined value. Rather but an object distance is measured again, and thus a probability of in-focus photographing is improved.

  • Patent number: 5682563
    Abstract: A camera which imprints alphanumeric messages on the film. The camera allows a user to view, in the order of most frequently used, the messages which can be imprinted. In order to reduce the cost of the camera, there is a dot matrix LCD display which can only display a limited number of characters which is less than the total number of characters of the largest message. After a user takes a picture, the dot matrix display scrolls through the message which has been imprinted on the film so that the user can confirm that the correct message has been imprinted. The speed at which the characters are scrolled or displayed is determined based on the total number of characters of the message. As an alternative to scrolling, the characters can be displayed one or two at a time. As an alternative, instead of displaying the alpha-numerical characters of the message, a graphical indication is given that some type of information has been imprinted on the film.

  • Patent number: 5678074
    Abstract: A power focus device for a camera provides a user-friendly lever interface allowing efficient camera operation. A lever, located outside a camera cover, is movable in two opposing directions but is biased to remain at a neutral position between two extremes of movement. Moving the lever from the neutral position initiates driving the camera lens to focus in either a first or a second direction according to a direction of a displacement of the lever from the neutral position. A speed of focusing is proportional to an amount of displacement of the lever from the neutral position, thus permitting variable high and low speed focusing in both directions for rapid and accurate close-up and infinity focussing. Incorporating a seal into the device permits use in underwater camera applications.
