Fixed focus camera module and its focus adjustment device and focus adjustment method

摘要

The present invention provides a fixed focus camera module, a method of manufacturing the same, a focus adjusting device, and a focus adjusting method, the focus adjusting method comprising the steps of: prefabricating an optical lens on a lens base, And the optical lens is positioned in a light path of a photosensitive element assembled on a circuit board to form a preassembled camera module, performing an imaging operation with the preassembled camera module to obtain a test image, Assembled camera module, the relative position between the optical lens and the lens base is adjusted until the high-quality image required by the pre-assembled camera module is outputted, and the optical lens and the lens base are fixed to each other, Thereby completing the assembled fixed-focus camera module.
