Abstract
An image sensor may include phase detection pixels that gather phase detection data. The phase detection pixels may be formed in phase detection pixel groups with two or more phase detection pixels covered by a single microlens. Each phase detection pixel may have an asymmetric angular response to incident light. Phase detection pixels may be covered by diffractive lenses. A diffractive lens may cover a phase detection pixel pair to improve angular separation between the pixels. A diffractive lens may partially cover a phase detection pixel in a phase detection pixel pair to shift the angular response and account for an off-axis chief ray angle of the phase detection pixel pair.
