The invention provides a camera component, a focal length setting method and a mobile terminal. The camera component comprises a bracket, a circuit board, an image sensor, an optical filter, a lens and a heating element, wherein a lens through hole is formed on the bracket, the lens is arranged in the lens through hole, the image sensor is arranged on the circuit board and arranged corresponding to the lens, and the optical filter is fixed between the image sensor and the lens; the lens comprises a temperature-variable optic, and the focal length of the temperature-variable optic is correspondingly changed along the change of the temperature; and the focal length of the temperature-variable optic is the first focal length when the temperature-variable optic is at the first temperature, andthe focal length of the temperature-variable optic is the second focal length when the temperature-variable optic is at the second temperature. When the focal length of the camera component needs toset, the temperature of the lens is controlled through the heating element, and the shape change of the temperature-variable optic is controlled through the temperature change, thereby changing the focal length of the lens; and an operation of driving a camera to move to focus by using a voice coil motor can be avoided, thereby reducing the space occupied by the camera component.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to a camera assembly, a focal length adjustment method and a mobile terminal. Background technique [0002] Mobile terminals such as mobile phones and tablet computers all have image acquisition functions such as taking pictures and video recordings, which enrich the user experience. These image acquisition functions are all realized by cameras. The cameras of existing mobile terminals such as mobile phones protrude from the surface of the housing. Due to the restriction, enough space must be reserved on the camera to accommodate the movement of the lens during focusing, so the existing camera will take up a large space. Contents of the invention [0003] Embodiments of the present invention provide a camera assembly, a focal length adjustment method, and a mobile terminal, so as to solve the problem that existing cameras occupy a large space. [0004] In order to solve the ...
