Image capturing apparatus having a focus adjustment function

摘要

When an FFP mode is set, a quick-return mirror and a sub mirror are driven between an inclined position and a horizontal position according to whether the focus point is within the image capturing area of a phase difference AF module or not. When the focus point is set within the image capturing area of the phase difference AF module, focus adjustment is performed by a phase difference detection method using the phase difference AF module. When the focus point is set outside the image capturing area of the phase difference AF module, focus adjustment is performed by a contrast detection method with the entire image capturing area as the object area of the focus adjustment.
