Abstract
An image sensor comprises a first imaging pixel and a second imaging pixel each of which detects an object image formed by a photographing optical system and generates a recording image. Each of the first imaging pixel and the second imaging pixel comprises a plurality of photoelectric conversion units segmented in a first direction, the plurality of photoelectric conversion units have an ability of photoelectrically converting images formed by split light beams out of a light beam from the photographing optical system and outputting focus detection signals to be used to detect a phase difference. A base-line length of photoelectric conversion units to be used to detect the phase difference included in the first imaging pixel is longer than that of photoelectric conversion units to be used to detect the phase difference included in the second imaging pixel.
