Omnivision Proposes RGB-IR CFA

Omnivision's patent application US20160104735 "Dual-Mode Image Sensor With A Signal-Separating Color Filter Array, And Method For Same" by Jin Li, Qian Yin, and Dyson Hsinchih Tai proposes RGB-IR CFA:


  1. Presumably, this is used in conjunction with a 660-900 nm (or thereabouts) blocking filter and 940 nm LED illumination.

  2. There are a lot of these patent apps floating around these days. I haven't found any that look enabling. There always seems to be some mystery material that has the proper spectral properties AND is easily reticulated for small pixels.

  3. RGB+IR and RGB+W have been around since at least 10 years; no significant breaktrough

    1. In principle, yes. The only question is whether Omnivision was able to find the magic materials to make this patent application work.
