Embodiments of this application provide an image obtaining method and a terminal device. When the terminal device moves, a motion sensor collects motion data of the terminal device, and sends the motion data to an optical image stabilization OIS controller and an electronic image stabilization EIS controller, where the terminal device includes the motion sensor, the OIS controller, the EIS controller, and an image sensor. The OIS controller controls, based on the motion data, a lens of the terminal device to move. The image sensor collects an image sequence. The EIS controller performs, by using movement information of the lens and the motion data, jitter compensation on the image sequence collected by the image sensor, so that stability of an obtained image can be improved.

The lens module faces the lighting module and includes a first lens aligned with the first light source, a second lens aligned with the second light source, a sliding frame, and a driving motor. The sliding frame is fixed to the first lens and has a thread portion. The driving motor has a screw rod for engaging with the thread portion, to make the sliding frame movable along the screw rod. The driving motor rotates the screw rod to make the thread portion drive the first and second lenses close to or away from the first and second light sources. Accordingly, the present invention reduces the manufacturing cost of the light emitting device and simplifies its mechanical design.
