Patent ID: 8687013

Claim:
A method for assessing color characterization quality of a display device comprising the steps of: determining at least one of a forward and inverse transform from a first set of device dependent input color values and measured output display values of the first set of device dependent input color values on the display; transforming a second set of device dependent input color values using said determined at least one of a forward and inverse transform to provide an intermediate set of device dependent input color values; and performing at least one of a forward transform quality evaluation and an inverse transform quality evaluation using at least said second set of device dependent input color values; wherein said forward transform quality evaluation comprises; transforming said second set of device dependent input color values using said determined at least one of a forward and inverse transform to provide an intermediate set of device independent output color values; and comparing said intermediate set of device independent output color values with measured output display values of said intermediate set of device dependent input color values on the display to determine a quality measure; and wherein said inverse transform quality evaluation comprises; transforming said second set of device dependent input color values using said determined forward transform to provide a second intermediate set of device independent output color values; and comparing said second intermediate set of device independent output color values with measured output display values of said intermediate set of device dependent input color values on the display to determine a quality measure.
