Patent ID: 8665289

Claim:
A color reproduction system comprising: a computer system having a link to at least one video display device; and memory storing data and programs, wherein said data comprise: a plurality of screens comprising graphical elements for display on said display device, wherein said screens provide an interface enabling user interaction with one or more of said programs; and information for transforming colors from device-independent coordinates to values employed in rendering to said display device, wherein at least part of said information is stored in a file and said information comprises at least a desired tone reproduction and color coordinates characterizing a desired neutral balance for said display device, stored values representing the tone reproduction and neutral balance initially associated with said display device, values representing neutral balance and tone reproduction for said display device modified in accordance with user visual judgments, and a chromatic adaptation transform enabling conversion of input color coordinates to output color coordinates representative of different viewing conditions, wherein at least said chromatic adaptation transform is accessible through a header of said file; and wherein said programs comprise: one or more programs for displaying said screens on said display device and recording modifications to neutral balance and tone reproduction curves based upon visual judgments of displayed screens by said user; one or more programs that use said visual judgments to set at least the brightness of said display device and to derive correction functions based upon said modifications; and one or more programs that modify said information for transforming in accordance with said correction functions and direct rendering of colors on said display device with improved matching to desired values.
