As shown in fig. 1, 2, 3, and 4, the present application provides an image pickup apparatus including: a housing 110; a driving assembly 120 disposed on the housing 110; a lens assembly 130 connected to the driving assembly 120; the first elastic element 140 is disposed on the housing 110 and connected to the lens assembly 130, and when the lens assembly 130 is displaced, the first elastic element 140 is elastically deformed, so that the capacitance of the first elastic element 140 changes, and the driving assembly 120 performs a focusing operation according to the displacement information of the lens assembly 130.

In the embodiment of the present application, the camera device includes a housing 110, a driving assembly 120, a lens assembly 130 and a first elastic member 140, the lens assembly 130 is mounted on the driving assembly 120, the driving assembly 120 is mounted on a base 112, and the lens assembly 130 and the housing 110 are connected by the first elastic member 140, so that the lens assembly 130 and the housing 110 are constrained by the first elastic member 140, and the movable range of the lens assembly 130 is limited, specifically, when the lens assembly 130 is displaced, the first elastic member 140 is elastically deformed, and when the first elastic member 140 is elastically deformed, the capacitance of the first elastic member 140 is changed, and according to the different displacement degrees of the lens assembly 130, the elastic deformation of the first elastic member 140 is also different, so that the different capacitance degrees of the first elastic member 140 can change the displacement degree of the lens assembly 130, the driving assembly 120 reflects the change of the capacitance of the lens assembly 130 according to the capacitance of the first elastic member 140, and thus achieves a focusing effect, and further improves a shake detection effect of the camera device, and a magnetic shake detection cost of the camera device is reduced.

That is, the first elastic member 140 elastically limits the lens assembly 130, so that the lens assembly 130 can move within a certain range, and when the lens assembly 130 is displaced, the first elastic member 140 is elastically deformed.

The shake of the lens assembly 130 is a certain displacement of the lens assembly 130, and the driving assembly 120 detects the displacement information of the lens assembly 130 through the capacitance change in the first elastic member 140, so as to perform corresponding focusing compensation, and form an anti-shake effect under continuous closed-loop control.

Moreover, the first elastic member 140 is an inherent component in the image pickup apparatus, and the addition of additional components is reduced, so that the positions of the components of the image pickup apparatus are sufficient, which is helpful for reducing the volume of the image pickup apparatus.
