Kodak boosts digital camera sensitivity

If it happened, it must be possible: A color sensing system consiting of luminance, red, and blue chennels has been demonstrated. I've seen unpublished examples at the Kodak Research labs. The key is to have broad sensitivity patterns on the red and blue channels as well as the luminance channel. We also need some overlap between the blue and luminance and between the red and luminance channels. In your example with two monochromatic sources that appear white when combined, the blue channel will detect some of they cyan source and the red channel will detect some of the yellow-orange source. The result will be close to white if the system is well calibrated.

All I'm really suggesting is using channels that approximate the CIE color matching functions. Check the plot of "CIE 1931 Standard Colorimetric Observer XYZ functions" at http://en.wikipedia.org/wiki/CIE_1931_color_space; Posted by: randrews4 Posted on: 06/15/07 You are currently: a Guest | Members login | Terms of Use
