Abstract: A camera assembly and a mobile terminal comprise an optical image stabilization motor with relatively large electromagnetic radiation, for example, a SMA motor. The SMA motor could be disposed on a lighting side of the lens assembly. Because an image sensor is located on an imaging side of the lens assembly, this can achieve a relatively long physical distance between the SMA motor and the image sensor, thereby reducing electromagnetic interference caused by the SMA motor to the image sensor.

Abstract: A voice coil motor for driving a liquid lens and a lens assembly having a voice coil motor, where the voice coil motor includes a plurality of sub motor parts. The sub motor parts can be independently controlled. The sub motor part includes an unmovable part, a movable part, which can move along an optical axis direction relative to the unmovable part, a connection elastic piece, coupled to the liquid lens and the movable part, where when a force is applied to the movable part in the optical axis direction, the movable part drives the connection elastic piece to squeeze the liquid lens.

Abstract: A lens control method is applied to a camera module with an OIS motor. The module includes a lens, an OIS motor, an OIS motor driver module, and an imaging sensor. The method includes: obtaining a first speed and a first direction of a to-be-photographed object in a moving process, an object distance between the to-be-photographed object and the lens, and an image distance between the lens and the imaging sensor; calculating a second speed and a second direction based on the first speed, the first direction, the object distance, and the image distance; and sending a control signal to the OIS motor driver module, so that the OIS motor driver module drives the OIS motor to control the lens to move at the second speed and in the second direction.

Abstract: A photographing apparatus includes a shape memory alloy (SMA) motor, an image sensor, a lens, and a controller. The SMA motor includes an SMA wire. The SMA wire is configured to deform to drive the lens to move. The controller is configured to output a pulse signal. The pulse signal includes a drive signal and a detection signal. The drive signal is used to cause the SMA wire to deform. The detection signal is used to detect deformation of the SMA wire. N times a pulse signal cycle is equal to a time difference between the first time of sampling and the second time of sampling in correlated double sampling of the image sensor.
