Abstract:
1. An image capturing apparatus comprising: photoelectric conversion means including a first pixel group which includes first pixels and a second pixel group which includes second pixels, wherein the first pixels photoelectrically convert an object image formed via a first exit pupil region of a photographing lens and the second pixels photoelectrically convert an object image formed via a second exit pupil region different from the first exit pupil region; focus detection means for detecting a focus of the photographing lens using a first image signal obtained from the first pixel group and a second image signal obtained from the second pixel group; calculation means for calculating an inclination of a straight line connecting a barycenter of the first exit pupil region and a barycenter of the second exit pupil region from a pixel arrangement direction of the first pixel group and second pixel group; and focus detection range setting means for setting a focus detection range based on a calculation result of said calculation means.
