Abstract
A photosensitive electronic diaphragm-shutter mechanism includes a diaphragm-shutter unit and a control unit. The diaphragm-shutter unit includes a first photosensitive electronic member and a second photosensitive electronic member, which are overlapped to be positioned. The control unit outputs signals to the first photosensitive electronic member and the second photosensitive electronic member respectively for controlling the transparent status or non-transparent status thereof. The time difference of the first photosensitive electronic member and the second photosensitive electronic member when transferring status decides a shutter time. The present invention also provides a controlling method for photosensitive electronic diaphragm-shutter mechanism.
