Abstract: It is provided a image capturing apparatus including a control unit that determines whether to set a division number to a first division number n or to a second division number m which is larger than n based on the setting status of an image capturing apparatus, calculating a divided area evaluation curve by calculating a correlation between first detection information and second detection information for each of divided areas formed by dividing a phase difference detection area into the n or the m, and acquires a defocus amount to drive and control a focus lens to the in-focus position from a total evaluation curve obtained by conducting a required calculation processing on the divided area evaluation curves of the plural divided areas.
