What is the principle of the camera module
2020-03-07
The working principle of the camera module is to project the scene to the surface of the image sensor through the lens, and then convert it into an electrical signal, and then convert it into a digital image signal by A/D (A/D), and then send it to the digital signal processing chip (D SP) for processing, and then transmit it to the computer through the USB terminal for processing. The main components of the camera module include the main control chip, the photosensitive chip, the lens and the power supply. Good power is also one way to make sure the camera is working. Camera lens: Five-glass lens is the mainstream.
For most people, the problem of camera modules is no longer a problem, and Shenzhen Zhongcai Optoelectronics Technology is only for Xiaobai. It says that lenses are made up of simple lenses, camera lenses or glass lenses are usually made of plastic lens elements. Glass lenses to get a clearer image than plastic lenses. This is because light passing through ordinary glass lenses typically loses only 5% to 9% of light, and plastic lenses lose up to 11% to 20% of light. Some lenses also use the technology of multi-layer optical coating, which effectively reduces refraction and noise filtering to improve the rate at which light passes through for a clearer image.
Nowadays, however, many small factories tend to reduce the number of lenses or use cheap plastic lenses in order to save costs and pursue high profits. While these products are much cheaper and look attractive, the actual imaging results are really not pleasing to the eye. At present, most of the cameras on the market use five-shot lenses, but there are also a few businesses that describe plastic lenses as five-shot lenses. Therefore, when consumers buy some miscellaneous cameras, they must try them out in detail and beware of being deceived.
