Canon to FINALLY produce a BSI sensor? (And it'll also feature Dual Pixel AF)

A recent patent application from Canon illustrates a design that's very similar to those found in Sony's own backside illuminated (BSI) sensors. These types of sensors are typically much better when it comes to low light performance and dynamic range, even when pixel sizes are relatively small.

Cameras with BSI technology essentially have two sections that have been switched around on the sensor. Previously, sensor technology had a configuration where the photo-diodes sat behind the wiring, thus sitting further away from the optical elements in the lens. This was less efficient compared to current sensor design where the photo diodes sit much closer to the optic.
