A limited number of voltage measurements are received from a multiple illuminant color sensor at the direction of a color sensor controller. The received sensor voltages are normalized in accordance with a calibration look-up table. Next, the normalized sensor voltages are converted to reflectance values based on a correction look-up table. Then, a reconstruction look-up table is used to convert the reflectance values at a predetermined wavelength to reflectance values with a predetermined wavelength separation. |
