What is a CMOS image sensor
CMOS image sensor is referred to as CIS, that is, an image sensor using CMOS technology, an image sensing element manufactured by the principle of photoelectric technology. CMOS image sensor has a better signal conversion ability, which can directly convert charge into voltage in the pixel, and exceeds the performance of traditional CCD sensors. At present, the mainstream cameras use CMOS sensors for signal conversion, and CMOS sensors are also widely used in mobile phones, digital cameras, automatic driving, security, IOT and other fields.
In recent years, the global CMOS image sensors have shown a steady growth trend. The global CMOS image sensor market size will be $25.3 billion in 2023, and the global CMOS image sensor market size will be $27.4 billion in 2024. CMOS image sensors in China is still in a stage of rapid development, 2021 sales of 29.5 billion yuan, an increase of 19%, the growth rate is significantly faster than the world, by 2024, the market size of 51.7 billion yuan, a compound growth rate of 20%.
The application scenarios of CMOS sensors in the field of security monitoring are traditional security and home security. CMOS sensors are divided according to sensitivity, ordinary, starlight and moonlight. CMOS sensors have different requirements for resolution. Of course, the application field of CMOS sensors is more than this, as mentioned above in smart phones, digital cameras, automatic driving, IOT and other fields are widely used.
