Novel arrangement of light-slits to improve a phase-detection ability for the on-sensor PDAF [Patent]

NIKON filed patent of novel arrangement of slits to improve a phase-detection ability on a heavily defocused image for the on-sensor PDAF.

Most pixels are split into several sub-pixels for an accurate phase-detection, but some special pixels have single light-slit with novel arrangement to help phase-detection for a heavily defocused image.
