New Fuji sensor patent
Jan 25, 2014

This is very clever and seems to combine both the earlier concept of different sized pixels and the concept of the Xtrans colour filter array.

It also matches what has been done in astrophotography for a long time. There we mainly use monochrome CCD chips and take clear, red, green and blue filtered images separately then combine them.

The clear filter (called luminance filter and is UV/IR blocked) has maximum detail and sharpness. The RGB forms the colour and is less detailed.

This type of imaging leaves a one shot colour sensor (Bayer matrix usually) for dead in terms of overall detail, shadow detail, colour and noise.

Kodak developed an alternative to the Bayer matrix as well and called it True Sense. They sold their sensor division to a company called True Sense Imaging. They sell these CCDs with the True Sense colour filter array (clear, r, g, b) and claim it is 2X more light sensitive compared to regular Bayer matrix CCDs.

So this new Fuji patent should see both less noise, more detail, a lot brighter and more sensitive and still excellent colour.

Couple that with their organic sensor R and D as well as the now mature XTrans colour filter array and Fuji is sitting pretty with a bag full of high tech sensor possibilities to make their cameras stand out from the competition.
