In the present application, for convenience of description, the following are defined: the direction of the light transmitted from the object image to the image sensor is from front to back, i.e. the transmission direction is from front to back.

Referring to fig. 1 to 3, a photographing module 100 provided in the present application will now be described. The shooting module 100 comprises a base 11, an image sensor 12, a lens 14, a voice coil motor 13 and at least one electrowetting lens 20, wherein the image sensor 12 is mounted on the base 11, the lens 14 is arranged in front of the image sensor 12, the voice coil motor 13 is mounted on the base 11, the lens 14 is mounted in the voice coil motor 13, and the voice coil motor 13 drives the lens 14 to move so as to realize focusing. The electrowetting lens 20 is disposed along the optical axis of the lens 14, and the electrowetting lens 20 is disposed in front of the image sensor 12, the electrowetting lens 20 being a lens based on the electrowetting effect. The electrowetting effect is a phenomenon that the wettability of a liquid drop on a substrate is changed by changing the voltage between the liquid drop and an insulating substrate, namely, a contact angle is changed, so that the liquid drop is deformed and displaced. When no voltage is applied to the electrowetting lens 20, the electrowetting lens 20 corresponds to a light-transmitting plate; when a voltage is applied across the electrowetting lens 20, the electrowetting lens 20 behaves as a lens, i.e. a voltage is applied across the electrowetting lens 20, which can change the curvature of the electrowetting lens 20.

When no voltage is applied to the electrowetting lens 20, the image sensor 12, the lens 14, and the voice coil motor 13 can realize a conventional focus shot. When a voltage is applied to the electrowetting lens 20, the electrowetting lens 20 is made to be equivalent to a lens, so that a microscope-like magnification effect is realized, the focusing distance can be shortened, and macro photography is realized.
