Abstract:
1. An image sensor comprising a plurality of image sensing pixel groups, wherein: each of said plurality of image sensing pixel groups has a plurality of first pixels each having a plurality of photoelectric conversion portions that are arrayed in a first direction for a first number of divisions and in a second direction that is perpendicular to the first direction for a second number of divisions, and a plurality of second pixels each having a plurality of photoelectric conversion portions that are arrayed in the first direction for a third number of divisions and in the second direction for a fourth number of divisions; the plurality of the photoelectric conversion portions comprising said first pixel and said second pixel have a function that photoelectrically converts a plurality of images formed by light fluxes transmitted through different regions of an exit pupil of an imaging optical system and outputs a focus detection signal; and the first number of divisions and the third number of divisions are coprime natural numbers greater than 1, and the second number of divisions and the fourth number of divisions are coprime natural numbers greater than 1; wherein the first number of divisions and the second number of divisions are different to each other, and the third number of divisions and the fourth number of divisions are different to each other, and a product of the first number of divisions and the second number of divisions and a product of the third number of divisions and the fourth number of divisions are equal.
