Abstract

Official abstract text for this publication.

A solid-state image sensor includes a semiconductor region including a plurality of photoelectric converters from which signals are allowed to be independently read out; a first microlens; and a second microlens which is arranged between the first microlens and the semiconductor region, wherein the second microlens includes a central portion and a peripheral portion that surrounds the central portion, and a power of the peripheral portion is a positive value and larger than a power of the central portion.

First claim

Opening claim text (preview).

What is claimed is: 1. A solid-state image sensor including a plurality of pixels for detecting focus based on a phase-difference detection method, each of the plurality of pixels including: a semiconductor region including a plurality of photoelectric converters from which signals are allowed to be independently read out for detecting focus; a first microlens; a second microlens, made of a single material, which is arranged between the first microlens and the semiconductor re…
