Against the backdrop of miniaturization development of electronic devices and continuous breakthroughs in preparation technology, CMOS sensors have once again become a hot research topic in the market.

CMOS sensors are image sensors manufactured using CMOS technology, whose main function is to convert optical signals into electrical signals. The photoelectric conversion principle is the same as CCD sensors. According to different pixel structures, it can be divided into two categories: passive pixel passive sensors (PPS) and active pixel active sensors (APS). The research on CMOS sensors and CCD sensors started in the late 1960s. CMOS sensors have shortcomings such as poor resolution, high noise, and low sensitivity. CCD sensors have become mainstream products in the market due to their advantages of low noise and few pixels. However, CCD sensors have problems with large volume, high heat generation, and high power consumption, which cannot adapt to the trend of miniaturization and low power consumption of electronic products. Against the backdrop of miniaturization development of electronic devices and continuous breakthroughs in preparation technology, CMOS sensors have once again become a hot research topic in the market.

Compared with CCD sensors, CMOS sensors have certain advantages in terms of cost, power consumption, volume, and integration. With their advantages, they have gradually been widely used in consumer electronics, automotive electronics, security monitoring, medical treatment, facial recognition, 3D scanning, and other fields. Currently, CMOS sensors have replaced CCD sensors as mainstream products in the image sensor market.

According to the report, as the application field expands, the scale of the CMOS sensor market will continue to grow. It is expected that the global market will grow at a compound annual growth rate of over 6.0% from 2023 to 2027. Industry analysts say that driven by factors such as technological iteration and demand upgrading, the application scenarios of CMOS sensors will continue to expand, with broad development prospects. The competition in the CMOS sensor market is relatively fierce. Foreign enterprises mainly focus on the high-end market, while domestic enterprises start late and have low technological levels. Currently, they mainly focus on the mid to low-end market. However, as domestic enterprises make technological breakthroughs and accumulate experience, they will continue to penetrate into the high-end market.
