Abstract:
1. A color-converting apparatus comprising: an inputting portion receiving input color data comprising input gradation levels for at least three input color components for an input end device; a color converting portion converting the input color data into output color data that comprises output gradation levels for at least three output color components for an output end device, the color converting portion executing the converting operation using conversion properties of the input end device and of the output end device; a determining portion determining whether one of the input gradation levels in the input color data is equal to a predetermined maximum input gradation level; and a correcting portion correcting the output color data into corrected output color data when the determining portion determines that one input gradation level in the input color data is equal to the predetermined maximum input gradation level, the corrected output color data comprising final output gradation levels for the at least three output color components, the correcting portion including:
