## Abstract

An image sensor includes an objective lens arranged on an optical axis; a substrate including a plurality of photoelectric conversion devices; and a micro lens layer including a plurality of micro lenses corresponding to each of the plurality of photoelectric conversion devices, respectively, wherein the plurality of micro lenses includes a central micro lens corresponding to a central portion of the objective lens, and an edge micro lens corresponding to an edge portion of the objective lens, and the plurality of micro lenses are configured such that focal lengths of the micro lenses increase from the central micro lens toward the edge micro lens.

## Claims

### Claim at position 1

-15. (canceled)

### Claim 16

An image sensor comprising:
a substrate;
a plurality of photoelectric conversion devices on the substrate;
an objective lens; and
a plurality of micro lenses in between the objective lens and the plurality of photoelectric conversion devices, the plurality of micro lenses being configured such that focal lengths of the plurality of micro lenses vary with horizontal distances between a center point of the objective lens and center points of the micro lenses.

### Claim 17 (depends on 16)

The image sensor of claim 16, wherein each of the plurality of micro lenses is disposed above a corresponding one of the plurality of photoelectric conversion devices.

### Claim 18 (depends on 17)

The image sensor of claim 17, wherein the plurality of micro lenses are configured such that corresponding first distances of the plurality of micro lenses vary with the horizontal distances between the center point of the objective lens and the center points of the micro lenses, and
for each of the plurality of micro lenses, the corresponding first distance is defined as a horizontal distance between a center of a surface of the micro lens and a center of the photoelectric conversion device corresponding to the micro lens.

### Claim 19 (depends on 17)

The image sensor of claim 17, wherein the plurality of micro lenses are configured such that vertical distances between the plurality of micro lenses and a surface of the photoelectric devices corresponding to the plurality of micro lenses vary with the horizontal distances between the center point of the objective lens and the center points of the micro lenses.

### Claim 20 (depends on 16)

The image sensor of claim 16 wherein, the plurality of micro lenses are configured such that widths of the plurality of micro lenses vary with the horizontal distances between the center point of the objective lens and the center points of the micro lenses.
