Abstract
In an image sensor having a plurality of pixels which photoelectrically convert a subject image, a plurality of pairs of focus detection pixels including first focus detection pixels (SHA) and second focus detection pixels (SHB) are arranged while being distributed. The first focus detection pixel (SHA) and the second focus detection pixel (SHB) of each pair of focus detection pixels are arranged at a distance shorter than the pitch of the pairs of focus detection pixels. This reduces focus detection errors generated when the pixels included in the pairs of focus detection pixels receive light fluxes from different portions of the subject.
