Abstract
A flare-suppressing image sensor includes a first pixel formed in a substrate and a refractive element located above the first pixel. The refractive element has, with respect to a top surface of the substrate, a height profile having at least two one-dimensional local maxima in each of a first cross-sectional plane and a second cross-sectional plane perpendicular to the first cross-sectional plane. Each of the first and second cross-sectional planes is perpendicular to the top surface and intersects the first pixel.
