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

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.
