Abstract
An image sensor may include pixels having nested sub-pixels. A pixel with nested sub-pixels may include an inner sub-pixel that has either an elliptical or a rectangular light collecting area. The inner sub-pixel may be formed in a substrate and may be immediately surrounded by a sub-pixel group that includes one or more sub-pixels. The inner sub-pixel may have a light collecting area at a surface that is less sensitive than the light collecting area of the one or more outer sub-pixel groups. Microlenses may be formed over the nested sub-pixels, to direct light away from the inner sub-pixel group to the outer sub-pixel groups in nested sub-pixels. A color filter of a single color may be formed over the nested sub-pixels. Hybrid color filters having a single color filter region over the inner sub-pixel and a portion of the one or more outer sub-pixel groups may also be used.
