Claim Text:
1. An imaging device for receiving a light flux from an exit pupil of an optical system, comprising: a first imaging area having a plurality of first pixels and a plurality of second pixels arranged therein; and a second imaging area having a plurality of first pixels and a plurality of third pixels arranged therein, wherein each of the first pixels being configured so as to receive a light flux from a first pupil area of the exit pupil and operate for photoelectric conversion, each of the second pixels being configured so as to receive a light flux from a second pupil area of the exit pupil and operate for photoelectric conversion, the second pupil area including a part of the first pupil area and being decentered relative to a center of gravity of the exit pupil to a first direction, each of the third pixels being configured so as to receive a light flux from a third pupil area of the exit pupil and operate for photoelectric conversion, the third pupil area including a part of the first pupil area and being decentered relative to the center of gravity to a second direction opposite to the first direction, the first imaging area being displaced to a direction corresponding to one of the first and second directions relative to a position on the imaging device where an optical axis of the optical system passes, the second imaging area being displaced to a direction corresponding to the other of the first and second directions relative to the position, the first imaging area only having the first and second pixels from among the first, second and third pixels arranged therein, or having the first, second and third pixels with the number of the second pixels being not less than five times the number of the third pixels arranged therein, the second imaging area only having the first and third pixels from among the first, second and third pixels arranged therein, or having the first, second and third pixels with the number of the third pixels being not less than five times the number of the second pixels arranged therein, and the first imaging area and the second imaging area being arranged at opposite sides of a first boundary line which passes through a geometric center of the imaging device and runs on the imaging device perpendicularly relative to the first and second directions so as to be interposed between the first and second imaging areas.
