According to the Research Report on Market Monitoring and Future Development Prospects of China's CMOS (Complementary Metal Oxide Semiconductor) Sensor Industry from 2023 to 2027, with the expansion of application fields, the market scale of CMOS sensors will continue to grow, and it is estimated that the global market will grow at a compound annual growth rate of over 6.0% from 2023 to 2027.
CMOS (Complementary Metal Oxide Semiconductor) sensor is an image sensor manufactured by CMOS technology. Its main function is to convert optical signals into electrical signals, and its photoelectric conversion principle is the same as that of CCD sensor. According to different pixel structures, CMOS sensors can be divided into two categories: passive pixel passive sensor (PPS) and active pixel active sensor (APS).
Compared with CCD sensors, CMOS sensors have certain advantages in cost, power consumption, volume and integration. With their advantages, CMOS sensors are gradually widely used in consumer electronics, automotive electronics, security monitoring, medical care, digital cameras, face recognition, 3D scanning and other fields. At present, CMOS sensors have replaced CCD sensors as mainstream products in the image sensor market.
The research of CMOS sensor and CCD sensor started in the late 1960s. In the early stage, due to the preparation technology, CMOS sensor has some shortcomings such as poor resolution, high noise and low sensitivity. CCD sensor has become the mainstream product in the market because of its advantages of low noise and few pixels. However, CCD sensor has some problems, such as large volume, large heating and highly power consumption, which cannot adapt to the development trend of miniaturization and low power consumption of electronic products. With the development of miniaturization of electronic devices and continuous breakthroughs in preparation technology, CMOS sensors have once again become a hot spot in market research.

At present, CMOS sensor suppliers in the world include SONY Semiconductor, OMNIVISION, SAMSUNG, SK HYNIX, ONSEMI, ROCKCHIP ELECTRONICS, SUPERPIX MICRO, GALAXYCORE, BYD Microelectronics, GPIXEL, etc., and the market competition is increasing day by day.
The research on CMOS sensors started late in China. At present, there is still a certain gap between domestic enterprises and foreign enterprises in terms of technology, scale, research and development, products, etc. However, under the general trend of domestic substitution, domestic enterprises are relying on independent core technologies, keeping close to customer needs, etc. to give full play to their own advantages, and constantly expanding to the middle and high-end markets. In response to the escalating market demand, CMOS sensor technology is also accelerating iteration, and ultra-high resolution, high sensitivity, ultra-miniaturization, multifunction and high dynamic range have become its important development direction.
Driven by technology iteration, demand upgrade and other factors, CMOS sensors will accelerate their evolution, and their application scenarios will continue to expand, so the industry will have broad development space in the future. The competition in CMOS sensor market is fierce. Foreign enterprises mainly lay out the high-end market, while domestic enterprises start late and have low technical level. At present, they mainly lay out the low-end market. However, with the technological breakthrough and experience accumulation of domestic enterprises, domestic enterprises will continue to penetrate into the high-end market.
