An image capturing apparatus includes an image sensing device that receives object light and generates an image signal relating to the object image, a phase difference detection unit that receives the object light using a ranging sensor and generates a phase difference detection signal, a first focusing unit for performing a first focusing operation on the basis of the phase difference detection signal, and a display controlling unit for displaying a preview image on the basis of a plurality of image signals sequentially generated by the image sensing device before an image is actually recorded. The display controlling unit combines a first area for which the phase difference detection is performed using the ranging sensor and the preview image so as to display the combined image.
