Claim:
1. A pixel array, comprising: a plurality of visible light pixels arranged in the pixel array, wherein each one of the plurality of visible light pixels includes a photosensitive element arranged in a first semiconductor die to detect visible light, wherein the plurality of visible light pixels is arranged in the pixel array having color filters arranged in a Bayer pattern having a repeating pattern of a red color filter, a first green color filter, a second green color filter, and a blue color filter to provide color image data, wherein each one of the plurality of visible light pixels is coupled to provide the color image data to visible light readout circuitry disposed in a second semiconductor die stacked with and coupled to the first semiconductor die in a stacked chip scheme; and a plurality of infrared (IR) pixels arranged in the pixel array, wherein each one of the plurality of IR pixels includes a single photon avalanche photodiode (SPAD) arranged in the first semiconductor die to detect IR light, wherein each one of the plurality of IR light pixels is coupled to provide IR image data to IR light readout circuitry disposed in the second semiconductor die, wherein each one of the plurality of IR pixels is surrounded on all lateral sides in the first semiconductor die by the plurality of visible light pixels, wherein the plurality of IR pixels is distributed throughout the pixel array among the plurality of visible light pixels in the first semiconductor die.
