Abstract:
A focus detection apparatus that performs phase difference focus detection based on signals of a plurality of colors obtained from an image sensor, which is covered by color filters of the plurality of colors, that performs photoelectric conversion on light incident on the image sensor via an imaging optical system and outputs electric signals, the apparatus comprising: an acquisition unit that acquires an addition coefficient indicating weights to be applied to the signals of the plurality of colors on the basis of characteristic of chromatic aberration of magnification of the imaging optical system; a generation unit that generates a pair of focus detection signals by performing weighted addition on the signals of the plurality of colors using the addition coefficient; and a detection unit that detects an image shift amount between the pair of focus detection signals.

Claim (Index 3):
The focus detection apparatus according to  claim 2 , wherein the information of the imaging optical system is lens identification information.
