Image sensor industry observation: lack of high-end products

After more than 30 years of development, China's security industry has rapidly emerged as an important force in the world's security industry. In addition to meeting the ever-expanding domestic security needs, domestic security companies' products are also exported to more than 100 countries and regions such as Europe, America, Middle East, Southeast Asia and Africa. However, image sensors that are particularly important in the security surveillance industry have been overlooked due to high technical barriers and strong dependence on foreign products.

Image sensor as the basis of system perception layer and data collection, its function and importance have far exceeded our original understanding of the sensor, it is not only an electronic component, but an indispensable sensory organ in the field of artificial intelligence. At the dawn of the era of Internet of Everything, image sensors can be said to be an important interface for the promotion of Internet of Things applications, and the "eye" of everything.

Image sensor product market potential is high, high-end products are lacking

At present, the CMOS market share has surpassed that of CCD, becoming the mainstream of image sensors. According to the analysis of French Yole Consulting, smartphones, automobiles and security are the three hottest areas of image sensing applications. For the security industry, CMOS image sensors are more advantageous at higher resolutions, providing high-quality video images and high dynamic range video data. They are fast-responding and more suitable for high-definition data monitoring. Used in monitoring equipment. From 2015 to 2020, the annual average compound growth rate of safety monitoring can be maintained at 36%, increasing to 912 million US dollars. Among them, most monitoring equipment adopts CMOS image sensor, and its market potential cannot be underestimated.

In recent years, driven by the demand in the fields of security and RFID tag cards, the sensor market has expanded rapidly. According to the Prospective Industry Research Institute's "2018-2023 China Sensor Manufacturing Industry Development Prospects and Investment Forecast Analysis Report", by the end of 2017, the total sales revenue of enterprises above designated size has reached 74.778 billion yuan, an increase of 10.02%.

The market is so large, but there are very few suppliers that can provide high-end CMOS image sensors. Except for a few Taiwanese companies, domestic manufacturers mainly provide low-end CMOS image sensors, and high-reliability image sensors such as aviation and aerospace also rely on imports. .

Domestic sensor companies are gradually developing

The US embargo on core chips in the first half of 2018 sounded the alarm for the sensor and application industries: If domestic companies do not increase their independent innovation, they will face a similar situation in the future.

In recent years, China's focus on the sensor industry has been continuously improved, and a series of policies have been introduced to promote its development. The Ministry of Industry and Information Technology and other four ministries jointly issued the Action Plan for Accelerating the Development of Sensors and Intelligent Instrumentation Industry, indicating that in the future, an innovative industrial cluster of over 10 billion yuan will be established in the field of sensors, and industry leading and output value exceeding 1 billion yuan will exceed A small but fine enterprise of 50 million yuan.

Faced with the strong demand for image sensor performance in the market environment, companies with strong technology and resources represented by Dahua, SmartSens and aerospace electronics have developed.

Dahua shares are mainly engaged in security products. The high-definition progressive scan image sensor is used for the integrated high-definition capture camera, which can realize high-speed capture of megapixel high-definition pictures, real-time video recording, license plate recognition, storage, retrieval, etc. It is a high-speed image acquisition and processing technology in the field of high-speed capture. Comprehensive application.

As a technology-driven company, SmartSens has gradually become the backbone of the high-end imaging sensor chip market in the domestic security industry. Its products meet high signal-to-noise ratio and high definition while using innovative high dynamic range. Technology to meet the wide dynamic range imaging needs of high speed motion scenes. In addition, SmartSens uses a low-power architecture design to effectively reduce product power consumption and make product design more adaptive.

Aerospace Electronics is a subsidiary of China Aerospace Science and Technology Corporation. Its high-performance sensors meet the requirements for military product development. Its core competitiveness lies in its strong technical development strength and rich production experience.

Conclusion

At present, the domestic sensor industry has developed, but domestic CMOS image sensors want to catch up with and even surpass foreign manufacturers. They must seek breakthroughs in technology and continue to innovate in sensor chip design technology. Only accelerate independent innovation, form industry leaders, and promote relevant The integration of domain technology can promote the development of the sensor industry and meet the demand for sensors in the Chinese market.
