Abstract:
An exposure adjusting apparatus, which comprises: an image sensor, for catching an image according to an exposure parameter; a computing apparatus, for computing an exposure amount of the image and for determining whether the exposure amount is in a predetermined exposure range or not; and an exposure updating apparatus. If the exposure amount is in the predetermined exposure range, the exposure updating apparatus does not adjust the exposure amount. If the exposure amount is not in the predetermined exposure range, the exposure updating apparatus generates at least one adjusting amount according to at least one of the predetermined exposure range, the exposure amount and the exposure parameter, and utilizes the adjusting amount to increase or decrease the exposure parameter to generate a new exposure parameter.
