  • Patent number: 7315397
    Abstract: When an input color signal of a first color space is converted to a color signal of a second color space having a color reproduction range narrower than that of the first color space, it is determined whether a color signal that is outside the color reproduction range of the second color space having the color reproduction range narrower than that of the first color space exists within the input color signal of the first color space. If it has been determined that a color signal outside the color reproduction range of the second color space exists, the hue system of the color signal represented in the first color space is converted to the hue system of the color signal represented in the second color space having the narrower color reproduction range.

  • Patent number: 7301667
    Abstract: A system or method of removing whitespace between tiled or repeated patterns generated during a printing operation. The system takes an initial image and determines if there exist extraneous bits of whitespace around the edge of actual image. Once this information is established, the printer application program uses that information to alter the tiled output accordingly to produce a seamless image with repeated or tiled patterns of the actual image.
