ASYMMETRICAL MICROLENSES ON PIXEL ARRAYS

摘要

An image sensor includes a plurality of photosensitive sites (100), a plurality of asymmetrical-shaped microlenses (130) positioned spanning the photosensitive sites(100); wherein incoming light is directed in a predetermined direction by an asymmetrical surface of the asymmetrical-shaped microlenses (120) onto the photosensitive sites (100) for capturing the light in a substantially uniform manner.
