Abstract
An imaging element has plural pixels which photoelectrically convert light rays having different colors, and has a light receiving surface on which the plural pixels are arranged in two dimensions according to a regular pattern, the plural pixels include first pixels that output signals each having a first color component which most contribute to obtainment of brightness signals, and second pixels that output signals having color components other than the first color component, the first pixels and the second pixels are as defined herein, and a pair row is formed on the light receiving surface as defined herein.

An imaging element that has a plurality of pixels which photoelectrically converts light rays having different colors, and has a light receiving surface on which the plurality of pixels is arranged in two dimensions according to a regular pattern,
- wherein the plurality of pixels comprises first pixels that output signals each having a first color component which most contribute to obtainment of brightness signals, and second pixels that output signals having color components other than the first color component,
- the first pixels comprise a first imaging pixel having a photoelectric conversion area in a reference position, a first phase-difference detecting pixel having a photoelectric conversion area in a position eccentric to one side in a predetermined direction with respect to the reference position, and a second phase-difference detecting pixel having a photoelectric conversion area in a position eccentric to other side in the predetermined direction with respect to the reference position,
- each of the second pixels is a second imaging pixel having a photoelectric conversion area in the reference position,
- a pair row constituted by pairs, which comprise a plurality of first pairs of the first phase-difference detecting pixels arranged in arrangement positions of the first pixels based on the pattern and the second phase-difference detecting pixels arranged in arrangement positions of the second pixels based on the pattern and a plurality of second pairs of the second phase-difference detecting pixels arranged in the arrangement positions of the first pixels based on the pattern and the first phase-difference detecting pixels arranged in the arrangement positions of the second pixels based on the pattern and are arranged in the predetermined direction, is formed on the light receiving surface,
- the plurality of first pairs included in the pair row is arranged so as to be closer to the one side from a predetermined position in the predetermined direction of the pair row, and
- the plurality of second pairs included in the pair row is arranged so as to be closer to the other side from the predetermined position in the predetermined direction of the pair row.
