An apparatus, if a live view image is not displayed in an enlarged manner on first and second display units, outputs, to the first and second display units, an image acquired by superimposing a guide indicating a degree of focus of a focus detection region, on the live view image, and if a live view image is displayed in an enlarged manner on the first display unit, outputs, to the first display unit, an image acquired by enlarging a partial region in the live view image that includes the focus detection region and superimposing the guide on the enlarged image, and outputs, to the second display unit, the live view image on which the guide is not superimposed.
