The working principle of a camera module is roughly as follows: the optical image generated by lens LENS is projected onto the surface of the image sensor, converted into an electrical signal, and converted into a digital signal processing chip(DSP) for processing. It is then transmitted to a computer through a USB interface for processing, and the image can be seen through the display.
Note 1: An image sensor is a semiconductor chip that contains hundreds millions of photodiodes on its surface. When a photodiode is illuminated by light, it generates an electric charge.
Note 2： The function of the digital signal process chip DSP is mainly to optimize the parameters of digital image signals through a series of complex mathematical algorithm operations, and transmit the processed signals to devices such as PC through USB and other interfaces. DPS architecture framework: 1.ISP(camera module image signal processor). 2, JPEG encoder. 3. USB device controller
