Color conversion device for applying clipping to color values outside a color reproduction range and which satisfy a predetermined condition
Abstract:
A color processing device includes a color range conversion component, a control component and a color conversion and clipping component. The color range conversion component performs a color range conversion of input color signals in accordance with a specified color range conversion condition. The control component excludes from objects of the color range conversion by the color range conversion component a color value, of the input color signals, of which a position in a predetermined color space is outside a color reproduction range and which satisfies a predetermined condition. The color conversion and clipping component, after a color space conversion, applies clipping to a color value that falls outside the color reproduction range of the designated device in the color space dependent on the designated device, including rounding off such that the color value falls in the color reproduction range.
