Abstract
In an image pickup device, a controller includes a surplus area calculation unit to detect a surplus area for use in correcting camera shake based upon a size of an effective area on an image pickup surface and a size of an efficient area extracted in response to camera shake. Thus, this image pickup device can prevent a troublesome aspect in which camera shake correction reaches the correction end from occurring, even when a large camera shake that is beyond the surplus area occurs.
