Abstract:
1. A solid-state imaging device comprising: a plurality of pixels; photodiodes which are formed separately for respective ones of the pixels arranged in a matrix shape on a light sensing surface of a semiconductor substrate; a signal reading unit which is formed on the semiconductor substrate and reads a signal charge generated and charged in the photodiodes or a voltage in accordance with the signal charge; an insulating film which is formed on the semiconductor substrate so as to cover the photodiodes and includes optical waveguides; color filters which are formed on the insulating film; and on-chip lenses which are formed on the color filters, wherein in a layout, first pixel combinations and second pixel combinations are alternately arranged both in horizontal and vertical directions, the first pixel combination having a layout in which two green pixels are arranged both in the horizontal and vertical directions and a total of four pixels are arranged while provided with a green color filter as their color filter, the second pixel combination having a layout in which two pixels are arranged both in the horizontal and vertical directions, a total of four pixels are arranged, and two red pixels having red color filters and two blue pixels having blue color filters are arranged so that the two red pixels and the two blue pixels are diagonally placed.
