Patent ID: 8670051

Claim:
A solid-state image sensor comprising a plurality of pixels, wherein the plurality of pixels includes a first pixel and a second pixel, wherein the first pixel includes an antireflection structure and a first color filter, wherein the second pixel includes an antireflection structure and a second color filter, wherein the solid-state image sensor satisfies: T 1(λ12)≦0.95 ·T max1, and T 2(λ12)≦0.95 ·T max2, where λ 1 represents a wavelength at which a transmittance of the first color filter is maximized, λ 2 represents a wavelength at which a transmittance of the second color filter is maximized, and λ 12 represents a central wavelength between wavelengths λ 1 and λ 2 , T 1 (λ) represents a transmittance of the antireflection structure of the first pixel, and T 2 (λ) represents a transmittance of the antireflection structure of the second pixel, where λ represents a wavelength, and Tmax 1 represents a maximum value of the transmittance T 1 (λ), and Tmax 2 represents a maximum value of the transmittance T 2 (λ), and wherein the antireflection structure of the first pixel and the antireflection structure of the second pixel have a same structure.
