摘要:
To provide a solid-state imaging device that can capture an image which is bright through to its periphery, even when used in a single-lens reflex digital camera that accepts various interchangeable lenses from wide-angle to telephoto. The solid-state imaging device includes a two-dimensional array of unit pixels each of which includes a light-collecting element. A light-collecting element in a unit pixel is a combination of circular-sector-shaped light-collecting elements having different concentric structures. A central axis of the concentric structures is perpendicular to a light-receiving plane of the light-collecting element. Each of the circular-sector-shaped light-collecting elements is divided into concentric zone areas of a width equal to or smaller than a wavelength of incident light. Thus, an image which is bright through to its periphery can be captured even when light incident on a unit pixel changes from wide-angle to telecentric (chief rays are approximately parallel to an optical axis).
