Claim:
1. An image pixel array, comprising: a plurality of photodiodes, wherein the image pixel array includes visible imaging pixels for detecting light in the visible spectrum and infrared imaging pixels for detecting light in the infrared spectrum; an array of microlenses, wherein each microlens focuses light onto a respective one of the photodiodes; a patterned layer of infrared light blocking material interposed between the array of microlenses and the plurality of photodiodes, wherein the infrared light blocking material transmits visible light and blocks infrared light, wherein the patterned layer of infrared light blocking material includes a plurality of openings, and wherein each opening is aligned with a respective one of the infrared imaging pixels; and a plurality of infrared pass filter elements, wherein each infrared pass filter element is formed in a respective one of the openings in the infrared light blocking material, wherein each infrared pass filter element is completely surrounded by the patterned layer of infrared light blocking material, and wherein each infrared pass filter element blocks visible light and transmits infrared light to a respective photodiode associated with the respective one of the infrared imaging pixels.
