Abstract
A method and apparatus for color calibrating an imager device is disclosed. The imager device is subjected to a plurality of light sources. Color channel responses are obtained from the imager device and the color calibrating coefficients are determined.
Claims5
A method of color calibrating an imager device, comprising:
- radiating a light from a plurality of different light radiation sources, the plurality of different light radiation sources having different spectral radiation characteristics and having known color values;
- illuminating the imager device with the light to produce a set of color channel responses;
- and
- determining color calibrating coefficients for the imager device from the set of color channel responses and the known color values.
