In a still image shooting mode, when a user does not specify a position of
an AF frame, an AF process is performed for an AF region of a
comparatively large range whose center is in a center of a shooting
frame. When the user taps on any position in an EVF area, a touch panel
superimposed on a display detects its coordinates. An AF region smaller
than the AF region when the user does not specify the position of the AF
frame is arranged so that a center of the AF frame is on the coordinates.
The AF process is carried out for the smaller AF region. When the user
taps on the EVF area 221 twice at a short predetermined interval, a PDA
returns the AF region to a state where the position of the AF frame 261
is not specified by the user.
