Abstract
A method for adjusting photosensitiveness is able to determine a relative distance of an object in an image capture area through images captured before and after pre-flash of a flash lamp, so that the relative distance serves as a reference for adjusting current photosensitiveness of the digital camera, thereby capturing an image having better quality in a status that the flash lamp provides a fill light.
