An image obtained by superimposing the image of the subject, which is displayed on the display screen of an electronic viewfinder, upon the optical image of the subject can be seen by the user looking through a finder unit. Display position on the display screen of the electronic viewfinder is shifted so as to correct for parallax between the finder unit and the solid-state electronic image sensing device. When the image of the subject is in focus, the optical image of the subject and the electronically captured image of the subject coincide. When the image of the subject is not in focus, the optical image and the electronically captured image are offset from each other. Correct focus can be achieved while observing the extent of offset between these images of the subject through the finder unit.
