Image sensor for depth estimation

摘要

An apparatus for acquiring intensity and depth information images may comprise: an image sensing unit having first radiation-sensitive elements and groups of second radiation-sensitive elements in a flat or curved plane having at least two directions, the first radiation-sensitive elements and groups of second radiation-sensitive elements to receive, respectively, an intensity image and a depth information image, at least two groups of second elements extending in each of the two directions of the plane; first micro-lenses, each of which is arranged to convey radiation to a corresponding one of the first elements; and second micro-lenses, each of which is arranged to convey radiation to a corresponding group of the second elements.

1. An apparatus for acquiring intensity and depth information images comprising:
an image sensing unit having first radiation-sensitive elements and groups of second radiation-sensitive elements in a flat or curved plane having at least two directions, the first radiation-sensitive elements and groups of second radiation-sensitive elements to receive, respectively, an intensity image and a depth information image, at least two groups of second elements extending in each of the two directions of the plane; first micro-lenses having a pitch approximately equal to that of the first elements, each of the first micro-lenses is arranged to convey radiation to a corresponding one of the first elements, and second micro-lenses, each of which is arranged to convey radiation to a corresponding group of the second elements, each combination of second micro-lens and corresponding group of the second elements having at least one of a light mask and a dead-zone in the group of the second elements to reduce the effective aperture of the second micro-lens.
