摘要:
Image values are adjusted based on image object or component type and in a perceptually linear manner based on user set control values. Image values are also scaled based on dynamic ranges of an input and output device, such as a monitor and a printer. A lookup table is generated for converting image values from an adjustment color space to a printer color space by measuring a test print, inverting the measured data to an adjustment color space and generating a final lookup table based on the adjustment color space data and the inversion color space data. Image values are adjusted in a perceptually linear manner by converting the image values to a perceptually uniform color space and adjusting the values in the adjustment color space before converting the values to a printer device space.
