Patent ID: 7155054

Claim:
A color management method comprises driving a monitor with a first plurality of input values in a first color space; determining a first plurality of output values in a second color space for the monitor in response to the first input values in the first color space; determining a first color space map between the first color space and the second color space in response to the first plurality of input values in the first color space and in response to the first plurality of output values in the second color space; determining a second plurality of input values in the first color space for a plurality of images; projecting the plurality of images with a first projector onto a projection screen; determining a plurality of projected values in response to the plurality of images projected onto the first projection screen; determining a second plurality of output values in the second color space in response to the plurality of projected values and in response to characteristics of a bulb for a second projector; determining a second color space map between the first color space and the second color space in response to the second plurality of input values in the first color space for the plurality of images and in response to the second plurality of output values in the second color space; and determining a color space map from input values in the first color space to modified input values in the first color space in response to the first color space map between the first color space and the second color space and the second color space map between the first color space map and the second color space.
