Abstract
Matching color information in an optical system can include splitting an image forming beam into a bright intensity beam and a dark intensity beam, detecting, using multiple sensors, a color value for a light component from the bright intensity beam and the dark intensity beam, determining color values for the remaining light components associated with the bright intensity beam and the dark intensity beam, and transforming the color values associated with the dark intensity beam to calibrate the color values of the dark intensity beam against the color values of the light intensity beam, the color values of the light intensity beam including color inaccuracies.
Claims17
A method for matching color information in an optical system, the method comprising:
- splitting an image forming beam into a bright intensity beam and a dark intensity beam;
- detecting, using multiple sensors, a color value for a light component from the bright intensity beam and the dark intensity beam;
- determining color values for the remaining light components associated with the bright intensity beam and the dark intensity beam;
- and
- transforming the color values associated with the dark intensity beam to calibrate the color values of the dark intensity beam against the color values of the light intensity beam, the color values of the light intensity beam including color inaccuracies.
A method for matching color information in an optical system, the method comprising:
- detecting light information using a plurality of sensors, each of the sensors having a plurality of pixels and each of the sensors receiving a different amount of light such that the detected light from each of the sensors is associated with a different color correction space;
- sequentially transforming the detected light information from a first color correction space to a target color correction space until the detected light information from each of the sensors is associated with a final color correction space;
- merging the detected light information and transformed light information associated with the final color correction space;
- color correcting the merged light information to correct for color inaccuracies using reference values.
