Abstract: A first area of a predetermined size is set as a focus area from which AF evaluation values are picked up in AF control when a focus mode is a normal one. When the focus mode changes to a macro mode, a second area narrower than the first area is set as the AF area. Thus, in the macro mode, focus search is performed automatically through the narrower area. AF frames indicative of the first and second areas are displayed on a through image.
