Abstract: A camera module includes a lens and a voice coil motor (VCM), and the lens is placed in the VCM, where a first portion of an inner side of the VCM is attached to a first portion of an outer side of the lens, and a second portion of the inner side of the VCM is provided with a screw thread structure recessed relative to the first portion of the inner side of the VCM. The screw thread structure and a second portion of the outer side of the lens form a groove portion, and the groove portion is filled with adhesive. The first portion of the VCM is a lower portion, and the second portion of the VCM is an upper portion. The first portion of the lens is a lower portion, and the second portion of the lens is an upper portion.

Abstract: A fingerprint recognition apparatus includes an optical film and an image sensor that are disposed at an interval of a first distance along a first direction. The optical film includes a first area and a second area, transmittances of the first area and the second area are different, the first area and the second area form a first pattern, and when receiving light reflected by a first object, the optical film converts the light into an optical image that has the first pattern and transmits the optical image to the image sensor. The image sensor is configured to receive the optical image and convert the optical image into an electrical signal. The electrical signal is used to construct an image of the first object.

Abstract: An optical image stabilization module and an electronic device. The optical image stabilization module includes a first bracket, a second bracket, and a third bracket that are nested in sequence from inside to outside, and an optical lens module fixed on the first bracket. A first connection assembly is arranged between the first bracket and the second bracket, to enable the first bracket and the second bracket to form a rotational connection about a first rotation axis. A second connection assembly is arranged between the second bracket and the third bracket, to enable the second bracket and the third bracket to form a rotational connection about a second rotation axis. The first rotation axis, the second rotation axis, and an optical axis of the camera are perpendicular to each other.
