Abstract

A camera device includes a base, an image sensing component and a gravity center adjustment mechanism. The image sensing component is located on the base. The gravity center adjustment mechanism includes a circuit board disposed on the base, an adjusting module and a weight component. An angle detecting unit on the circuit board is used to detect an inclined angle of the circuit board related to a reference surface. The adjusting module is disposed on the circuit board. The weight component is connected to the circuit board via the adjusting module. An processing unit on the circuit board drives the adjusting module to rotate the weight component according to the inclined angle, so as to change position of a gravity center of the camera device and to adjust a capturing angle of the image sensing component.
