  • Publication number: 20030002735
    Abstract: There is described a method of processing an image recorded on a film, by which differences of gamma values between RGB image information and information on foreign substances or damages are corrected. The method comprises the steps of: irradiating a plurality of lights, whose wavelengths are different relative to each other, onto the film; reading the image by detecting the plurality of lights transmitted through the film or reflected from the film placed, so as to generate a plurality of color image data sets corresponding to a plurality of color images included in the image; and processing the plurality of color image data sets, so as to keep each of relative relationships or each of ratios, between gamma values of the plurality of color images, substantially constant.

  • Patent number: 5777121
    Abstract: The present invention provides a method for carrying out a chemical reaction comprising the steps of forming an organic/fluorous solubilizing liquid phase comprising a solvent system. The solvent system is selected or adapted to substantially solubilize a fluorous reaction component or components (that is, a fluorous reagent, a fluorous catalyst and/or a fluorous reactant). The "fluorous reaction component" is functionalized to comprise at least one fluorous moiety having the formula -(R).sub.d (Rf).sub.e. (Rf).sub.e is at least one fluorous group and e is a whole number. (R).sub.d is an organic (for example, hydrocarbon) spacer group, which may be present or absent, and d is an integer equal to at least zero. The solvent system is also adapted to substantially solubilize an organic reaction component or components. After the reaction occurs in the organic/fluorous solubilizing liquid phase, a phase separation into at least a fluorous phase and an organic phase is effected.
