Focus on the four sectors of the industry and continue to innovate CIS technology

In recent years, CIS has benefited from the rapid development driven by policy dividends, and is growing in the security monitoring, intelligent automobile, consumer electronics and industrial application markets. The increasing popularity of smartphone multi camera, the progress of ADAS assisted security and the performance ability of CIS in low light and other lighting environments are promoting the realization of CIS for security purposes.

According to yole data, 98% of the market revenue of global CIS products comes from six markets: smart phone, security monitoring, automatic driving, computer, industry and consumer electronics. Smart phones (accounting for 68%) ranked first; Security monitoring, computer and automatic driving followed by 8%, 8% and 7% respectively; Consumer electronics and industry accounted for 4% and 3% respectively.

According to Stevie data, the company’s CMOS image sensor business mainly includes four sections: security, vehicle electronics, machine vision, mobile phone and consumer. Among them, security and machine vision account for more than 90% of its total revenue, and vehicle electronics, mobile phones and consumer products are also taking advantage of the wind.

In the field of security, the trend of high-definition image sensor is becoming more and more obvious. Tan Yang, vice president of security chip department, pointed out that the demand for 2k and above increased significantly, the demand for 4K increased significantly, and the demand for ultra-high resolution expanded to 8K. More market applications require cis to have higher frame rate, 4K / 8K clear imaging, rich HDR combination, excellent noise control and excellent night vision imaging.

In view of this, new products of Starway 4K Pro HD “sc850sl” and “sc830ai” and 8K Pro HD CIS appeared at this press conference. According to his introduction, steway has launched 16 new security products in 2021. From 100 million pixels to 800 million pixels, the full coverage of high, middle and low is realized.

With the development of automobile, it tends to the direction of intelligence, automation and electrification. Shao Ke, vice president of Stevie automotive chip department, said that at present, the carrying capacity of single camera of smart car can be as high as 15, including 1 rear view camera, 4 360 ° look around cameras and 1 ~ 3 streaming media applications in the vehicle image category; In the on-board perception ADAS, there are 1 ~ 3 in front view and 4 in side view.

In response to the huge market demand. In the field of vehicle electronics, Stevie’s new vehicle chip department was established, which enables three vehicle intelligent vision application directions by virtue of domestic self-developed vehicle image sensor technology: vehicle image application, vehicle perception ADAS application and in cabin application. It also innovatively launched the new “sc120at” of car regulation level two in one CIS + ISP. In addition, a number of on-board CIS products are also about to be mass produced.

IPO launch meeting, plus CMOS image sensor

Ma Weijian, chief operating officer, said that Stevie will continue to cultivate the field of CMOS image sensors and provide better services for customers by adhering to the product value of “based on the market and excellent quality” and the service concept of “thinking what customers think and giving customers what they can”.

In October this year, steway’s IPO was held and its listing is imminent. The company plans to raise more funds to continuously cultivate CMOS image sensors in security, machine vision, vehicle electronics, mobile phones and other fields.

Specifically, in terms of CIS investment, sitway independently developed and systematically upgraded the image sensor test platform, upgraded equipment and CMOS image sensor technology.
