Abstract
A method and system for formatting characteristic CRT information into a standardized format to provide a dynamic CRT characteristic profile to enhance presently used methods of recalibrating CRTs is disclosed. Present CRT parameters are measured and combined with previously acquired calibration parameters in order to create updated characteristic information for the profile. The characteristic information includes the CRT color gamut, the white and black point of the CRT and the gamma of the CRT. In addition, ambient lighting conditions may be included in the profile. This characteristic information is stored in a CRT characterization profile in a standardized format. The profile is updated whenever the CRT is recalibrated or whenever the operating conditions of the CRT are changed. Further, the profile may be employed to recalibrate a destination CRT based on a source CRT's profile.
