Abstract
A method and apparatus that outputs an optimally-converted image using predefined data and color characteristics. The method includes: receiving the color characteristics; converting the received color characteristics into a range of lightness; converting the range of lightness and the received color characteristics into a gamut of lightness and chroma to be represented by the printer; and adaptively outputting the image according to the converted range of lightness and the received color characteristics.
Claims13
A method of outputting an optimally converted image using color characteristics of an input image or an input device, the method comprising:
- receiving the color characteristics that include a maximum lightness and a minimum lightness that can be output by the input device or a maximum lightness and a minimum lightness of a pixel of the input image;
- converting a range of lightness in the received color characteristics into converted color characteristics including a range of lightness that can be represented by a printer;
- converting a gamut of the converted color characteristics including the converted range of lightness that can be represented by the printer into a converted gamut which includes a range of lightness and chroma that can be represented by the printer;
- and
- adaptively outputting the input image as an optimally converted image according to the converted gamut of the received color characteristics.
An apparatus comprising:
- an information input unit which receives color characteristics of an input image or an input device, wherein the color characteristics include a maximum lightness and a minimum lightness that can be output by the input device or a maximum lightness and a minimum lightness that exist in a pixel of the input image;
- a lightness/contrast output unit which converts a range of lightness in the received color characteristics into converted color characteristics including a range of lightness that can be represented by a printer;
- a lightness/chroma output unit which converts a gamut of the converted color characteristics that include the converted range of lightness that can be represented by the printer into a gamut which includes a range of lightnesses and chroma that can be represented by the printer;
- and
- an output unit which outputs the input image as an optimally converted image according to the converted gamut of the received color characteristics from the lightness/chroma output unit.
A computer readable recording medium storing a program for causing a computer to execute a method of outputting an optimally converted image using color characteristics of an input image or an input device, the method comprising:
- receiving the color characteristics that include a maximum lightness and a minimum lightness that can be output by the input device or a maximum lightness and a minimum lightness of a pixel of the input image;
- converting a range of lightness in the received color characteristics into converted color characteristics including a range of lightness that can be represented by a printer;
- converting a gamut of the converted color characteristics that includes the range of lightness that can be represented by the printer into a converted gamut of lightness and chroma;
- and
- adaptively outputting the input image as an optimally converted image according to the converted gamut.
