We do know that Nikon is also working to introduce Hybrid AF Sensors inside DSLR at the same time they are also working to Improve the Phase AF Sensor of the camera. The patent also mentions generation of High Resolution by sensor shift technique.
Patent Details translated
To provide a focus detecting device and an imaging device that can correct defocus amount precisely in accordance with spherical aberration of an imaging optical system.SOLUTION: A focus detecting device comprises: a microlens array 161 in which a plurality of microlenses 161a are arranged; a plurality of light receiving sections 162a provided in correspondence with the microlenses; a light receiving element 162 which receives light beams from an optical system through the microlenses; and calculating means 163 which selects a pair of light receiving sections, among the plurality of light receiving sections, receiving a pair of light beams passed through different regions of the optical system in association with a plurality of aperture values of the optical system, and calculates an amount of image plane shift in the optical system on the basis of output from the pair of the light receiving sections.SELECTED DRAWING: Figure 2
