CMOS image sensor (CIS) is a chip that converts photons into electrons for digital processing and is used to convert image signals into digital signals. It is a key component in digital cameras, digital closed-circuit television cameras and digital cameras, and is widely used in smart phones, security monitoring, automotive electronics, consumer electronics, industrial machine vision and medical fields. With the progress of science and technology and the demand of the market, the CMOS image sensor industry has ushered in unprecedented development opportunities.
From the perspective of market demand, smart phones are the largest application area of CMOS image sensors. With the increase in the number of mobile phone cameras and the improvement of resolution, the demand for CMOS image sensors continues to grow. In addition, security monitoring, automotive electronics, consumer electronics and other fields also put forward higher demand for CMOS image sensors.
The CMOS image sensor market is a market with a high degree of monopoly, and the top three companies occupy most of the market share. SONY is the industry leader, with a market share of about 39%; Samsung followed with a 23% market share; Weil (Haowei Technology) ranked third, with a market share of 13%.SONY's image sensors are mainly used in mobile phones, cameras, cameras and other fields, with strong technical strength, and its products are widely used in Apple, Huawei, Xiaomi and other major mobile phone manufacturers. Samsung's products are mainly used in their own mobile phones, and the cost performance is higher. Weil's image sensors focus on the security and automotive sectors.
It is expected that by 2025, the global CMOS image sensor market will continue to grow. With the rapid development of smart phones, security monitoring, automotive electronics and other fields, the demand for CMOS image sensors will continue to increase. As one of the world's important CMOS image sensor markets, China's market scale will also be further expanded, and the growth rate is expected to exceed the global average.
In addition to traditional smart phones, digital cameras and other fields, CMOS image sensors in security monitoring, automotive electronics, consumer electronics, industrial machine vision and medical applications will continue to expand. Especially in the field of security monitoring, with the advancement of smart cities, safe cities and other projects, the demand for high-definition, intelligent monitoring equipment will continue to increase, thus promoting the application of CMOS image sensors in this field.
