Optical technology of mobile phone camera module aspheric mirror optical coating technology

Overview of mobile phone camera module the imaging process of the camera is the process of digitizing the optical signal. The light first passes through the lens and reaches the photosensitive element, which may be CCD or CMOS. The function of both is to convert the light into digital signal, and then the digital signal is transmitted to a special external processor (DSP), After the image signal is enhanced and compressed and optimized, it is transmitted to the mobile phone or other storage devices. From this, we can see that each device has an impact on the overall performance of the camera. Mobile camera module is mainly composed of lens, sensor, back end + IC and FPC. The most important factors that determine the quality of a camera are lens, sensor and DSP. The key technologies of camera mobile phone are: optical design technology, aspheric mirror manufacturing technology, optical coating technology, etc. Main components of camera module.
