摘要：An image capturing apparatus comprises a photoelectric conversion unitincluding a first pixel group which photoelectrically converts an object image formed via afirst exit pupil region of a photographing lens and a second pixel group which
photoelectrically converts an object image formed via a second exit pupil region; a focusdetection unit which detects a focus of the photographing lens using a first image signalobtained from the first pixel group and a second image signal obtained from the secondpixel group; a calculation unit which calculates an inclination of a straight line connecting abarycenter of the first exit pupil region and a barycenter of the second exit pupil regionfrom a pixel arrangement direction of the first pixel group and second pixel group; and afocus detection range setting unit which sets a focus detection range based on acalculation result of the calculation unit.
