Abstract:
1. A solid-state image pickup device, comprising: a semiconductor substrate; and a plurality of photoelectric conversion elements arranged on a surface of said semiconductor substrate both in a line direction and in a column direction substantially perpendicular to the line direction to form a tetragonal lattice, wherein said photoelectric conversion elements include a plurality of high-sensitive photoelectric conversion elements and a plurality of low-sensitive photoelectric conversion elements, the plurality of high-sensitive photoelectric conversion elements configured to perform photoelectric conversion with higher sensitivity relative to the plurality of low-sensitive conversion elements, wherein said plurality of high-sensitive photoelectric conversion elements and said plurality of low-sensitive photoelectric conversion elements are arranged in a checkered pattern such that the high-sensitive photoelectric conversion elements and the low-sensitive photoelectric conversion elements alternate one by one in both the line and column directions, wherein each photoelectric conversion element is sensitive to a single color, and wherein for each high-sensitive photoelectric conversion element sensitive to a particular color, the high-sensitive photoelectric conversion element is relatively more sensitive to luminance relative to each of the low-sensitive photoelectric conversion elements that are sensitive to the same particular color.
