Abstract
A method for capturing an image, suitable for an image capturing apparatus with a flash lamp, is provided. In the invention, a pre-flash image is captured when a pre-flash is fired by the flash lamp. An intensity of a main flash is estimated. Whether the pre-flash image is overexposed is determined for calculating an overexposure number. A brightness comparison data is looked up according to the overexposure number and a brightness target value, so as to reduce a photosensitivity. A raw image is captured according to the reduced photosensitivity when the main flash is fired by the flash lamp.
