  • IMAGE PICKUP DEVICE AND AUTOMATIC CLEANING ASSEMBLY THEREOF
    Publication number: 20200201032
    Abstract: An image pickup device includes a camera module and an automatic cleaning assembly. The automatic cleaning assembly includes a first rotation structure, a second rotation structure and a motive power source. A first end of a light-transmissible film is connected with the first rotation structure. A second end of the light-transmissible film is connected with the second rotation structure. The motive power source drives the rotation of at least one of the first rotation structure and the second rotation structure. As the at least one of the first rotation structure and the second rotation structure is rotated, the light-transmissible film is correspondingly moved. Consequently, the front side of the camera module is covered by a clean segment of the light-transmissible film.
