Abstract:
A system comprises a digital imaging system for capturing digital images. The system includes a controller that captures at least one digital image, determines a brightness level of at least one bright region of the digital image, and generates brightness data representing the brightness level of the at least one bright region. The brightness data is compared with compositional information for determining a maximum brightness level of the at least one bright region of the digital image. The maximum brightness level comprises a level of brightness where information about the at least one bright region remains. The controller then determines an exposure value of a final digital image, where at least one region of the final digital image has a brightness level equal to or less than the maximum brightness level. At least one final digital image is then captured.
