[0002] In order to ensure that a camera module can maintain clear image output in different environments, and take into account the two environments with very large brightness differences during the day and at night, the camera module needs to add different IR filters to adapt to different environments, such as using a 650nm filter during the day and an 850nm filter at night. In order to ensure that the IR filter has a good and adaptive effect, the camera module often adds an IR-CUT switch accessory.
