Abstract: A camera module is provided. The camera module may be separately used as a camera, or may be applied to a terminal device such as a mobile phone or a tablet computer, or a vehicle-mounted device. The camera module includes an optical lens component, a light filtering layer, an image sensor and a drive module. The optical lens component is configured to receive a light beam from a photographed object, and transmit the light beam to the light filtering layer. The light filtering layer is configured to move a position under the drive of the drive module, and respectively transmit light signals filtered at different positions to the image sensor. The image sensor is configured to receive the light signals at the different positions from the light filtering layer, and determine image information based on the light signals at the different positions.

Abstract: An optical image stabilization apparatus includes a first lens, a first reflector, a position sensor, a control component, and a housing configured to enclose the first lens and the first reflector, where the position sensor is connected to the control component. An optical signal is transmitted to the first reflector after passing through the first lens. The first reflector reflects the received optical signal, and the reflected optical signal is projected onto an imaging plane. The position sensor is configured to detect shaking information of the first lens and send the shaking information to the control component. The control component is configured to control, based on the shaking information, the first reflector to rotate by using a first preset direction as an axis, where the first preset direction is a direction that is not parallel to a normal direction of the first reflector.
