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.
