Abstract
A method and an apparatus to reduce the errors in linearly transforming the RGB values to the XYZ values of the colors of an image. The image is measured twice, once with and once without a filter between the image and the sensors measuring the image. The apparatus is capable of generating at least three output values substantially simultaneously to measure the color of each element of the image.
