  • Patent number: 6232055
    Abstract: Disclosed is a silver halide color photographic photosensitive material in which the photosensitive layer of the photosensitive material comprising a silver halide emulsion, a developing agent and a coupler is put together with the processing layer of a processing material so that these layers are heated to form a color image in the photosensitive material, said silver halide grains in the photosensitive layer having a silver chloride content of 50 mol% or more, wherein (1) the silver halide grains, in which 50% or more of the exterior faces of the grain is made up of a (111) plane, account for 50% or more of the total projected area of the silver halide grains of the emulsion, and the developing agent has a specific molecular structure, or (2) the tabular silver halide grains having an aspect ratio of 2 or more, which have the exterior faces of the grain made up of a (100) plane and a plane of projection of the grain in a shape of a rectangle with a length to width ratio ranging from 1:1 to 1:2, or which hav

  • Patent number: 6218088
    Abstract: An image formation method for forming a color image by imagewise exposing a color negative type silver halide photographic material comprising a transparent support having provided thereon at least three kinds of light-sensitive layers, followed by development processing at a temperature of 50° C. or more, which comprises the steps of reading with an imaging apparatus an image obtained from the color negative type silver halide photographic material whose sensitivity and gradient satisfy the following relationship, applying digital image processing thereto, and then, obtaining output signals of three or more colors: 1.0≦(log10S)·&ggr;≦2.5 S≧800 wherein S represents an ISO sensitivity, and &ggr; represents an average gradient of the three kinds of light-sensitive layers, thereby inviting no failure in shooting due to insufficient exposure in a compact camera or a film with lens, and forming a color image of high quality.

  • Patent number: 6200738
    Abstract: An image forming method is disclosed, wherein a photographic element comprising a support having on at least one side thereof at least a photographic component layer containing light sensitive silver halide is subjected to exposure and photographic processing to form a dye image, in which the photographic processing is allowed to be completed, while the residual silver content in the photographic element is 5% or more; image information in the visible light wavelength region, in which the dye image has absorption, and image information in the invisible light wavelength region are read, and the obtained image information is further subjected to image processing to reduce noise due to the residual silver.

  • Patent number: 6183933
    Abstract: A photosensitive material which when imagewise exposed to record a latent image thereon is formed with an image by heating with a prescribed processing material superimposed thereon is used as a photographic film or the like, the photosensitive material is exposed to record an image thereon, the exposed photosensitive material is developed by superimposing and heating the photosensitive material and the processing material to form the image on the photosensitive material and then peeling the photosensitive material formed with the image off the processing material, the developed image on the photosensitive material is read with a scanner to obtain image data representing the image, and the image data are subjected to prescribed image processing to generate reproducible digital image data.
