New FOVEON sensor using dual (not triple) layers of pixels to improve readout speed [Patent]

SIGMA, an owner of FOVEON, filed a patent of a sensor using dual layers of pixels to improve readout speed.

【公開番号】特開2018-195961(P2018-195961A) click here

Each pixel has two layers of "B and G" or "G and R" as shown in a figure of embodiment.

All pixels have G layer (a) and missing colors of R or B at each pixels are interpolated as virtual Bayer array (b).
Sensor structure (a) and virtual Bayer array (b)

This method would be help an improvement of readout speed of a triple layer type FOVEON sensor for a high frame rate live-view and video recording.
