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.

Abstract: A processing process of a multi-lens camera module includes the following steps. Firstly, a first lens module and a first photosensitive element are installed on a first circuit board, and the first circuit board is fixed on a casing. Then, a second lens module and a second photosensitive element are installed on a second circuit board, and a bottom glue is coated on a lower portion of the second lens module. Then, the second lens module is adhered onto the casing through the bottom adhesive. After an optical axis parallel adjustment process is performed, the second lens module is in parallel with the first lens module. Then, a top glue is coated on an upper portion of the second lens module. After a baking process is performed, the top glue and the bottom glue are cured completely.
