Whether it's pure vision or multi-sensor fusion solutions, cameras are almost standard equipment for smart cars. As the core sensor of the perception layer, with the continuous upgrading of ADAS functions, car mounted cameras are facing opportunities for both quantity and price. The automotive camera industry chain mainly involves three main links: upstream materials, midstream components, and downstream products.
Upstream includes optical lens, filters, protective films, adhesive materials, CMOS image sensors, DSP signal processors, module packaging, etc; The midstream can be divided into front view cameras, surround view cameras, rear view cameras, side view cameras, built-in cameras, etc. according to the installation location; Downstream is widely used as a component in the automotive industry.
From the cost analysis of car mounted cameras, CMOS chips account for the largest proportion, exceeding half; In addition, module packaging accounts for 25%, and optical lens account for about 15%.
Due to the influence of internet car manufacturing thinking, the concept of automotive supply chain level is very vague, and upstream suppliers can provide complete camera products to downstream vehicle manufacturers. At present, the main market share holder is the Tier 1, a first tier car, with a customer base that basically covers major global vehicle companies.
Compared to applications in mobile phones and security, in car CMOS mainly has higher requirements for safety, reliability, low illumination, dynamic range, and functional safety in image quality. The application scenarios of in car CMOS are mainly divided into three types: 360 surround view, reverse camera, driving recorder, etc; The second is ADAS, autonomous driving, etc; The third is the application of DMS and other cockpit applications. According to market trends, future market growth points will mainly come from fields such as ADAS and autonomous driving.
According to different driving levels of L1-L5, the demand for CMOS image sensors per car will exceed 20. According to market data, the global in car CMOS market value in 2021 was 3.81 billion US dollars, of which the market value for front-end devices was 3.14 billion US dollars. It is expected that by 2026, the global in car CMOS market value will reach 9.07 billion US dollars, with the total value of the front-end market reaching 8.28 billion US dollars.
Stewei
After acquiring Allchip in 2020, STW started the research and development of its in car CMOS series products in 2021, with application scenarios including 360 degree panoramic imaging, driving recorder, cockpit monitoring, electronic rearview mirrors, ADAS, electronic rearview mirrors, and other fields. In the same year, STW also launched the front end product SC120AT, achieving mass shipment of the entire vehicle project and obtaining new project targets from multiple car factories.
According to the company's 2022 midterm report, the revenue from automotive electronics was 65.99 million yuan, an increase of 15.2% compared to the same period last year, accounting for 6.5% of the main revenue.
