New Olympus patent discloses two layer sensor

Olympus has patented a multi-layer sensor design which should help improve the color reproduction. Usually infrared light deteriorates the color performance of a sensor. And in this new patent Olympus added an infrared sensible sensor on the bottom of the classic RGB sensor. This way…

…Olympus subtracts infrared light information included in the visible light image captured by an upper-layer image sensor using infrared light information included in the infrared light image captured by a lower-layer image sensor so as to prevent the deterioration of the color reproducibility of the visible light image.
A subtracts a pixel value of an infrared light image from a pixel value of a visible light image to prevent the deterioration of the color reproducibility of the visible light image.

As usual with patents we will never know if this will be applied on MFT cameras. Afterall it sounds expensive to not have just one…but two sensors in a camera!
