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.
