摘要： A method is provided of correcting brightness without, or with reduced, hue-shift of a pixel color represented as a set of primary-color values in a reproducing device's color space, by means of a composite transformation that has the property that it preserves the hueless character of gray pixels and is made up of independent primary-color related transformations. At least some of the primary-color related transformations include applying a virtual color transformation to a primary-color value of the pixel color to be brightness-corrected, thereby transforming the primary-color value into a primary-color value of a virtual gray-idealized color space. A brightness change is applied to the primary-color value in the virtual color space, and the inverse of the virtual color transformation is applied to the brightness-changed primary-color value. Thereby brightness-changed primary-color value is transformed back to a primary-color value of the reproducing device's color space.

摘要： Certain examples relate to a method of color matching by confirming a color-rendering device. Color reproduction parameters are determined for a reference and target color-rendering device. A color matching parameter is determined for the target color-rendering device based on a comparison of the color reproduction parameter for the target color-rendering device with the corresponding color reproduction parameter of the reference color-rendering device. The color-rendering device is confirmed dependent on the color matching parameter. Color resources of the target color-rendering device are configured such that a rendering of a color image on the target color-rendering device replicates a rendering of the color image on the reference color-rendering device.
