LENS ARRAY FOR PARTITIONED IMAGE SENSOR

摘要

An apparatus includes an image sensor having N image sensor regions arranged thereon. A lens array having a including N lens structures is disposed proximate to the image sensor. Each one of the N lens structures is arranged to focus a single image onto a respective one of the N image sensor regions. The N lens structures include a first lens structure having a first focal length and positioned the first focal length away from the respective one of the N image sensor regions. A second lens structure having a second focal length is positioned the second focal length away from the respective one of the N image sensor regions. A third lens structure having a third focal length is positioned the third focal length away from the respective one of the N image sensor regions. The first, second and third focal lengths are different.
