An image capturing device is provided. The image capturing device includes an aperture unit, an image sensor, and a first lens unit. The first lens unit includes a first light-entering end and a first light-exiting end for focusing an external light on the image sensor. The aperture unit, the first lens unit, and the image sensor are sequentially arranged in a travel direction of the external light.

An optical element driving mechanism is provided. The optical element driving mechanism includes a movable portion, a fixed portion and a sensing assembly. The movable portion is connected with an optical element. The movable portion is movable relative to the fixed portion. The sensing assembly senses whether the movable portion is in a first position relative to the fixed portion.

An aperture module includes a base plate configured to have a central opening and include a pivot pin protruding from one corner area of the base plate, a pair of first blades configured to pivot about the pivot pin to form a first aperture diameter smaller than a diameter of the central opening, a pair of second blades configured to pivot about the pivot pin to form a second aperture diameter smaller than the first aperture diameter, a cover plate, comprising a cover guide slot, configured to cover the pair of first blades and the pair of second blades positioned on the base plate, and an aperture driver, comprising a driving pin coupled to a blade slot disposed in either one of the pair of first blades or the pair of second blades and the cover guide slot and configured to move along the cover guide slot.
