Abstract
A solid-state imaging device according to the present invention includes, on an imaging surface, a plurality of unit pixel regions being arrayed at a first pixel pitch along a Y direction and at a second pixel pitch along an X direction. One of two adjoining unit pixel regionsalong the Y first direction includes a first photodetecting portionhaving a first opening ratio, and the other includes a second photodetecting portionhaving a second opening ratio which is lower than the first opening ratio. When the first photodetecting portionis moved imaginarily by a first pixel pitch along the Y direction, the first photodetecting portioncovers the entire second photodetecting portion. At this time, a portion of the first photodetecting portionthat does not cover the second photodetecting portionfunctions as an imaginary third photodetecting portion. From a difference between signals output from the photodetecting portionsand, an imaginary pixel signal which is in accordance with an amount of light entering the imaginary third photodetecting portion is obtained.
