Abstract:
An image sensor equipped with imaging pixels disposed in a two-dimensional array, which converts an image formed through an optical system to an electrical signal, includes: first focus detection pixel groups each formed by disposing in the array of the imaging pixels a plurality of first pixels adopting a split pupil method; and second focus detection pixel groups each formed by disposing in the array of the imaging pixels a plurality of second pixels adopting a split pupil method different from the split pupil method adopted in the first pixels, and a relationship between a number of the first focus detection pixel groups and a number of the second focus detection pixel groups is determined in correspondence to directions of positions assumed by the first focus detection pixel groups and the second focus detection pixel groups relative to a center of the image sensor.
