In the embodiment of the present application, focusing is achieved by adopting a mode of moving the imaging chip 1021 instead of a mode of moving the lens 1011 in the prior art. The essence of camera focusing is that the distance between the lens 1011 and the imaging chip 1021 varies. In the prior art, the moving part of the auto-focusing camera is a motor and a lens 1011 driven by the motor, the imaging chip 1021 and other optical parts are kept still, and the distance from the lens 1011 to the imaging chip 1021 is adjusted by pushing the lens 1011 through the motor, so that the effect of focusing and clarity under different distances is achieved.

The lens 1011 does not need to reserve a space for dustproof foam on a screen or a battery rear cover, the lens 1011 can be directly contacted with the dustproof foam, so that the dustproof effect is improved, the whole machine is also beneficial to being designed thinner, and better vision and hand feeling can be provided for users; for the ultra-wide angle camera, a mushroom head for shielding the light can be added, so that the shell 1012 and the gap between the lens 1011 and the shell 1012 can be shielded to a greater extent, and the fineness of the whole camera is improved.
