  • Image converting method and image converting apparatus
    Patent number: 7817853
    Abstract: An image converting method includes the steps of: converting each pixel of an input image into 2-dimensional conversion chromaticity coordinate values which are obtained by projecting conversion chromaticity coordinate values obtained by converting each of said pixels by using parameters for converting in chromaticity coordinates onto a unit plane, and obtaining parameter values in which a barycenter of a color region including the 2-dimensional conversion chromaticity coordinate values are set to ?; and converting the input image by the obtained parameter values.
    Type: Grant
    Filed: March 17, 2009
    Date of Patent: October 19, 2010
    Assignee: Oki Data Corporation
    Inventors: Nobuhito Matsushiro, Noboru Ota

  • Image converting method and image converting apparatus
    Publication number: 20040091147
    Abstract: An image converting apparatus has: a parameter setting unit which sets parameters for converting each pixel of an input image into predetermined chromaticity coordinate values; a chromaticity coordinate converting unit which obtains conversion chromaticity coordinate values obtained by converting each pixel by the set parameters; a color region obtaining unit which obtains a color region including 2-dimensional conversion chromaticity coordinate values obtained by projecting each conversion chromaticity coordinate value onto a unit plane; an area calculation processing unit which calculates an area of the color region obtained every parameter and obtains parameter values at the time of the maximum area value; and an image converting unit which converts the input image by the parameter values. The image data unbalanced in color arrangement of an object is converted into image data obtained under an ideal white light source.
