Abstract: A lens module and an electronic device include a lens barrel and an optical component. The lens barrel includes a barrel wall and a clamping member protruding from a first inner side wall of the barrel wall. The clamping member includes a second inner side wall close to the optical axis. The second inner side wall of the clamping member is a sloped surface on a section paralleled to the optical axis, and the sloped surface is inclined from the object side to the image side toward a direction close to the optical axis. The clamping member is resisted against an outer side of the optical component. Thus, when the optical component is engaged with the clamping member, a single optical component can be smoothly fixed and arranged on the clamping member at the corresponding position.

Abstract: Provided is a method and a device for correcting lateral chromatic aberration, a storage medium and a computer equipment. In the method, a relationship model between lens position and magnitude of LCA is constructed based on preset parameters of lens positions, and the relationship model is stored as calibration data; system parameters of a camera to be corrected and pre-stored calibration data are obtained; the LCA of the camera to be corrected is obtained by calculating the system parameters; and the LCA is corrected by the calibration data. With the method, the LCA of the lens can be removed when the focus distance is changed, and the method is suitable for mass-production.
