SENSOR ASSEMBLY WITH SELECTIVE INFRARED FILTER ARRAY

An image sensor (270) includes both visible pixels (130R, 130G, 130B) and infrared pixels (130I). The visible pixels produce signals indicative of light within a visible band received by the visible pixels, and the infrared pixels produce signals indicative of light within an infrared band received...

More Information
Summary:An image sensor (270) includes both visible pixels (130R, 130G, 130B) and infrared pixels (130I). The visible pixels produce signals indicative of light within a visible band received by the visible pixels, and the infrared pixels produce signals indicative of light within an infrared band received by the infrared pixels. A selective infrared (SIR) filter array is integrated on the image sensor. The SIR filter array (260) includes SIR pixel filters that are positioned to filter out light within the infrared band propagating to the visible pixels. In this way, infrared crosstalk to the visible pixels can be reduced.
