Abstract
We describe silicon retina system that has robust color detection against changes in illumination color. Silicon retinas used have a logarithmic response and a function of a Laplacin-Gausian-lilae spntine filterimg. An input image is divided into red, green, and blue channels by color filters attached to camera lens. Then, opposite color responses, namely, red-green and yellow-blue awe calculated with output images from the silicon retinas, we enabled the color constancy of the system.
