Classification: CPC H | IPC H

Claim 0:
1. A solid-state image sensor, comprising:
a semiconductor substrate having photoelectric conversion elements that form an N×N pixel array, N is a positive integer larger than or equal to 3;
a modulation layer disposed above the photoelectric conversion elements; and
a light-adjusting structure disposed on the modulation layer,
wherein the N×N pixel array shares the light-adjusting structure and comprises:
a first pixel region having at least one first pixel; and
a second pixel region adjacent to the first pixel region in a first direction and in a second direction different from the first direction and having second pixels,
wherein an aperture ratio of the at least one first pixel and an aperture ratio of one of the second pixels are different,
wherein the light-adjusting structure is a converging micro-lens, and the solid-state image sensor further comprises:
a grid structure disposed in the modulation layer to divide the modulation layer into a first modulation segment corresponding to the at least one first pixel and second modulation segments corresponding to the second pixels,
wherein a material of the grid structure comprises a transparent dielectric material that has a refractive index in a range from 1 to 1.99, or the grid structure is air.
