| 1. An image-capturing apparatus comprising:
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 which picks up an image of the subject by driving the first image pickup element and the second image
pickup element simultaneously;
a displacement detecting unit which computes 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 which corrects a position of image data obtained from the first image pickup element, based on
the amount of displacement computed by the displacement detecting unit.
