  • Patent number: 7088395
    Abstract: The invention concerns an image-capturing apparatus and an imager. The image-capturing apparatus includes the imager in which a plurality of circuit cells are two-dimensionally aligned, and an electronic charge, photo-electronically converted from a received light and stored in each circuit cell, can be discharged from an arbitral circuit cell. The imager includes first group circuit cells to generate electronic charges corresponding to the pixels of the image including a subject, and second group circuit cells to generate electronic charges corresponding to an amount of light coming from the subject, the electronic charges further being converted to a detected value. In the imager, at least one of two operations of halting a generating-action of the electronic charges in the first group circuit cells and discharging the electronic charges from the first group circuit cells is performed, when the detected value exceeds a threshold value.

  • Patent number: 6341200
    Abstract: A lens-fitted film unit includes: a main body; a photographic lens provided in the main body, having an aperture value; an aperture provided in the main body; a shutter provided in the main body, having a shutter speed; a photographic film loaded in the main body, having image frames each including an unexposed portion and a pre-exposed portion on which a latent image has been formed; and a masking member for masking the pre-exposed portion of the photographic film when a photographing operation is conducted. The latent image has been formed on the photographic film with a same exposure amount as that obtained when an object to be photographed having a brightness of not less than 10 and not more than 12.5 in terms of light values in which a photographic film whose ISO sensitivity is 100, is exposed to light with an aperture value of the photographic lens set by the aperture and with the shutter speed of the shutter.

  • Publication number: 20010022617
    Abstract: The present invention concerns a system for recycling an electronic-image recording apparatus such as an electronic camera, etc., which can be used again. The system includes a restricting device to restrict an image-capturing operation under a predetermined condition occurring after use of the electronic-image recording apparatus, a readout section to read a first image signal in the basis of an image signal stored in the electronic-image recording apparatus, a converting section to convert the first image signal, read by the readout section, into a second image signal, and a canceling section to cancel the image-capturing restriction set by the restricting device included in the electronic-image recording apparatus.

  • Patent number: 6219446
    Abstract: An image forming apparatus includes: a first reading device for reading an image recorded on a recording medium; a storing device for storing a signal of a reference image representing a reference to correct the image recorded on the recording medium; a second reading device for reading a chart image obtained by recording the reference image; a calculating device for calculating image correction data by comparing the signal of the reference image with a signal of the chart image; an image processing device for correcting the image signal read by the first reading device on the basis of the image correction data; and an outputting device for outputting an image on the basis of the image signal corrected by the image processing device.

  • Patent number: 5771400
    Abstract: A camera comprising a backframe opening for exposing successive frames of a filmstrip, a film platen for supporting each film frame over the backframe opening, a chamber for a film cassette, and a film egress slot located between the backframe opening and the chamber to permit each exposed frame to be moved from the backframe opening into the cassette, is characterized in that a light-blocking resilient material is located at least sufficiently across the slot to prevent light at the backframe opening from shining through the slot to the film cassette and is located adjacent the platen to urge the filmstrip against the platen to hold the filmstrip stationary during exposure of each film frame at the backframe opening.
