An object is shot continuously at such a high shutter speed that blur is
not caused due to camera shake, and plural shot images are combined such
that object images in the plural shot images coincide with each other,
whereby one sharp image of the object is obtained. A correction direction
mark is displayed together with a through image during a shooting
operation. The correction direction mark indicates a direction and amount
to be corrected by its size, when a location of the object image in each
shot image shifts from an initial location in an initial shot image out
of a predetermined allowable range. Watching the correction direction
mark, a user can correct the shooting range so as to meet with the
initial shooting range, whereby the shooting range can be prevented from
shifting greatly from the initial shooting range during the shooting
operation.
