Sigma announces "Foveon X3 Quattro direct image sensor" with top blue sensing layer split into four pixels, on top of the single green and read pixels:
The new split-blue approach is said to increase the sonsor's resolution by 30% to be equivalent of that of 39MP Bayer sensor.

| The new 1:1:4 structure (bottom 1: middle 1: top 4) offers higher resolution that is equivalent to 39 megapixels for conventional color filter array sensors. In addition to the higher resolution, the sensor offers enhanced noise characteristics and faster processing and writing to memory of high-volume image data. |
