  • Patent number: 6326974
    Abstract: A coloring support apparatus comprises a table storage section to store a coloring table having an emphasis column for describing the degree of color emphasis of a domain in a linear graphic image to be colored, and a color coordinate column for describing a color coordinate value in any color space in the domain to be colored for each image element constituting the linear graphic image, a whole color tone column for describing the impression of coloring; a color number determination section for determining the number of colors according to the coloring table; a hue determination section for determining hue values according to the number of colors obtained by the color number determination section; a reference coordinate determination section for determining the tone, saturation and brightness of a color corresponding to the impression of coloring described in the whole color tone column; a color generation section for determining the saturation and brightness values of the hue of colors according to coordina

  • Patent number: 5398118
    Abstract: In a digital halftone screen generating device for generating a digital halftone screen comprising a plurality of periodic patterns, a configuration determining section (53) determines a grid (27) indicative of a configuration of one of the periodic patterns in the digital halftone screen by using periodic constants (51). Supplied with the periodic constants (51) and a function (50) defining a procedure for obtaining threshold values in a square area, a threshold value distributing section (54) rotates the threshold values defined by the function (50) by a screen angle. The threshold value distributing section (54) expands on the grid (27) threshold values enlarged by an enlargement ratio. When the threshold values on the grid (27) have discontinuous numbers, the threshold value distributing section (54) rearranges the threshold values so as to have continuous numbers.
