Abstract

According to embodiments, a solid-state imaging device includes a plurality of pixel cells. The plurality of pixel cells includes a first green pixel cell and a second green pixel cell. The first green pixel cell detects first green light of a first wavelength region. The second green pixel cell detects second green light of a second wavelength region. The second wavelength region includes the first wavelength region. A half-value width of a function representing a spectral sensitivity characteristic of the second green pixel cell is larger than a half-value width of a function representing a spectral sensitivity characteristic of the first green pixel cell.

First claim

What is claimed is:

1. A solid-state imaging device comprising:
an image sensor including a plurality of pixel cells configured to share detection of each color light;
a signal processing circuit configured to perform a signal processing of an image signal captured by the image sensor,
wherein the plurality of pixel cells includes a first green pixel cell configured to detect first green light of a first wavelength region, and a second green pixel cell configured to detect sec…
