Patent ID: 7847852

Claim:
A solid-state imaging device comprising: an image capturing unit having unit cells arranged in a two-dimensional array, each unit cell including a photoelectric conversion element and an upward convex microlens disposed above the photoelectric conversion element, at least one unit cell being positioned in a peripheral part of the image capturing unit, wherein a summit of the upward convex microlens in the at least one unit cell positioned in the peripheral part of the image capturing unit is displaced from a center thereof to a point closer to a center part of the image capturing unit, wherein at least one unit cell is positioned in the center part of the image capturing unit, and the upward convex microlens in the at least one unit cell in the center part of the image capturing unit has a cross-sectional shape that is line symmetric with respect to a line which (i) is perpendicular to a light incidence surface of the photoelectric conversion element and (ii) passes through a summit thereof, and the upward convex microlens which is in the at least one unit cell in the peripheral part of the image capturing unit has a cross-sectional shape that is line asymmetric with respect to the line which (i) is perpendicular to the light incidence surface of the photoelectric conversion element and (ii) passes through the summit thereof.
