摘要： Sensitometric information is stored with a consumable print medium having a predetermined sensitometry by compressing the sensitometric information as a set of spline coefficients for use with a printer adapted to decode the set of spline coefficients to construct a sensitometric curve. A set of spline coefficients is generated, spline coefficients are encoded, and the encoded spline coefficients are stored in a manner which is accessible to a printing device adapted to make use of the media sensitometry data for purposes of device calibration. The coefficient-generating step comprises fitting a spline curve to the sensitometry data. The spline curve may be monotonic cubic. The encoding step may include encoding a difference signal representing a difference between input values for a set of sequential spline knots. The encoding step may also include encoding a difference signal representing a difference between the output values of the sensitometry curve and output values of a reference sensitometry curve for each of a set of sequential spline knots. The difference signal may be encoded by quantizing the difference signal into a set of discrete bins.

摘要： A method for transforming input color values of a digital image to produce suitable output color values for use by a particular device is disclosed. In this method a plurality of color transforms are stored, each such transform responds to input color values of a digital image and produces output color values which can be used by the particular device. In the method an intermediate transform which is user desirable for transforming the input color values is formed by interpolating between the plurality of transforms.

摘要： This invention provides a method for transforming an input color space to an output color space where each of a plurality of specified colors and/or color regions are constrained to be transformed by any one of a plurality of explicitly specified color calibration or color enhancement strategies. The method involves a two step process: 1) constraints are applied to some subset of the points in the input color space explicitly specifying the transform into the output color space; 2) the reminder of the points are then transformed by a mapping strategy which preserves color continuity. The mapping strategy used in the preferred embodiment is based on a computer graphics geometric morphing technique. In the preferred embodiment, multi-dimensional look-up tables are used to implement the color transformation.
