An image-capturing apparatus includes a first image pickup element which
picks up an actual image of a subject, a second image pickup element
which detects a displacement and has sensitivity that is higher than that
of the first image pickup element, an image pickup unit for picking up an
image of the subject by driving the first image pickup element and the
second image pickup element simultaneously, a displacement detecting unit
for computing an amount of displacement between images due to a camera
shake using image data obtained from the second image pickup element when
the image of the subject is picked up by the image pickup unit, and a
position correcting unit for correcting a position of image data obtained
from the first image pickup element, based on the amount of displacement
computed by the displacement detecting unit.
