Shift
Center pixel
(aligned)
Edge pixel
(with shift)
The center axes of the microlens and the photodiode coincide for the center pixels. For the edge pixels,
there is a shift between the axis of the microlens and the photodiode causing a peak response incidence
angle (CRA) that deviates from the normal of the pixel array.
