Abstract
An image sensor comprises a plurality of pixels covered by color filters and arranged two-dimensionally in a first direction and a second direction perpendicular to the first direction; and a read out means capable of reading by switching between a first read out method for reading a signal from each of the plurality of pixels and a second read out method for reading by adding signals in the first direction within each pixel group including a predetermined number of pixels covered by a color filter of a same color. The plurality of pixels include a plurality of pixel groups of first focus detection pixels and a plurality of pixel groups of second focus detection pixels, arranged discretely, and the first and second focus detection pixels are partially shielded from light on different sides in the second direction so as to receive light transmitted through different exit pupil regions.
