Abstract: Embodiments disclosed herein reduce petal flare. A flare-suppressing image sensor includes a plurality of pixels including a first set of pixels and a second set of pixels. The flare-suppressing image sensor further includes plurality of microlenses, where each microlens is aligned to a respective one of the first set of pixels. The flare-suppressing image sensor further includes plurality of sub-microlens, where each microlens array is aligned to a respective one of the second set of pixels.

Abstract: A flare-reducing image sensor includes a plurality of pixels, NP in number, and a plurality of microlenses, NML in number, where each of the plurality of microlenses is aligned to a respective one of the plurality of pixels, such that NP=NML. The flare-reducing image sensor further includes a plurality of phase-shifting layers, NL, in number, where each phase-shifting layer is aligned with a respective one of the plurality of microlenses, where NL, is less than or equal to NML.
