Implantable CMOS image sensor with incident‐angle‐selective pixels

Angle‐selective pixels fabricated by using metal layers of the image sensor chip are proposed. Four incident‐angle‐selective pixels share one aperture. The selective pixel has a peak at 40° and full width at half maximum of ∼23°. An image sensor composed of normal and angle‐sensitive pixels was designed and fabricated. The reconstruction of a high‐resolution image from the blurred image using five different views is demonstrated.
