Solid state imaging device

A solid state imaging device comprising:

• a plurality of pixel sets, each including N (N is an integer greater than or equal to two) pixels and a microlens, the each pixel having a photoelectric converter for accumulating charge in accordance with incident light, the microlens condensing light into each of the N pixels, the N pixels being arranged in a rectangular region with a height and width ratio of approximately 1:2 such that the each photoelectric converter is line-symmetric or rotationally symmetric with respect to a center of the rectangular region in a width direction, an optical axis of the microlens being substantially coincident with the center of the rectangular region, size of the microlens being larger than a length of the rectangular region in a height direction and smaller than a length of the rectangular region in a width direction;
• pixel rows each composed of the pixel sets arranged in the width direction;
• and
• an imaging surface in which the pixel rows are arranged in the height direction, the adjacent pixel rows being shifted from each other by half the rectangular region in the width direction, a portion of the microlens extending beyond the rectangular region overlapping a space between the two microlenses of the two adjacent pixel sets in the adjacent pixel row.
