In 1974, while working for Kodak, Bayer completed his design for the Bayer filter, for which he filed a patent application in 1975 and in 1976 received U.S. patent number 3,971,065. The filter employs what is called the "Bayer Pattern," a checkerboard-like arrangement of red, green, and blue pixels on a square grid of photosensors that allows digital cameras to capture vivid color images. Half of the pixels collect green light, and the others are evenly divided between red and blue light. The patent application described the filter as "a sensing array for color imaging" that "includes individual luminance- and chrominance-sensitive elements that are so intermixed that each type of element...occurs in a repeated pattern with luminance elements dominating the array." In the early eighties, Bryce explained that, as needed, the filter provides more information on luminance and less information on chrominance.
