  • Patent number: 9985063
    Abstract: An imaging device that includes an array of photo detectors each configured to generate an electrical signal in response to received light, and an array of color filters disposed over the array of photo detectors such that the photo detectors receive light passing through the color filters. Each of the color filters has a color transmission characteristic, which vary. To even out color balance, some of the color filters are disposed over a plurality of the photo detectors while others are disposed over only one of the photo detectors. Additional color balance can be achieved by varying the relative area sizes of the color filters and underlying photo detectors based on color transmission characteristics, to compensate for the varying absorption coefficient of the photo detectors at different colors.
