Abstract
An image sensor includes a first pixel array. The first pixel array includes multiple photo diodes and a polyhedron structure. The polyhedron structure is located above the photo diodes, and the polyhedron structure includes a bottom facet, a top facet, and at least one side facet. The bottom facet is located between the side facet and the photo diodes, and an orthogonal projection of the polyhedron structure overlaps with photo diodes. The polyhedron structure is configured to divide an incident light into a plurality of light beams focused in the photo diodes.
