On September 8, 2021, Shanghai, China – smartsens, a technologically advanced CMOS image sensor supplier, officially launched a full series of new upgraded image sensors equipped with dsi-2 technology – sc2336 and sc3336, enabling the development of 2mp-3mp security and on-board intelligent video applications with high-quality video solutions.

With the arrival of the wave of intelligent video, the demand for CIS products in various application fields has surged. According to the prediction of yole, a well-known research organization, the global CIS market may reach US $31.5 billion by 2026, and the fields such as automobile and security monitoring will become the main driving force driving the rapid development of CIS market.

Dsi-2 technology, night vision full-color clearer!

The two new CMOS image sensors released this time adopt stevio dsi-2 technology, which effectively improves the dark light imaging performance of the products. Taking sc2336 as an example, its sensitivity is significantly improved by 46.2% compared with the previous generation products, and combined with stevio’s innovative sfcpixel ® With patented technology, the two products can still output excellent night vision full-color images in low illumination environment.

HD images day and night!

At the same time, sc3336 can realize dual pixel conversion gain imaging of high gain and low gain by virtue of the unique pixgain technology of stway, providing different gain options for day and night scenes to better adapt to the changes of ambient light. At the same time, compared with the previous generation products, the full well electron of sc3336 is significantly increased by 60%, and the dynamic range is increased by 5dB. It can output clear images during the day or at night.

Lower noise and more colorful!

Both sc2336 and sc3336 are equipped with stevio ultra-low noise peripheral reading circuit technology, combined with theater level color visual effect technology, so as to present a more delicate and realistic night vision full-color imaging. Taking chroma of sc2336 as an example, the low color temperature increased by 15% and the high color temperature increased by 11.8%.

In addition, for the glare caused by backlight, compared with the previous generation products, the electrical crosstalk of sc2336 and sc3336 are significantly reduced by 45% and 35% respectively, which improves the light overflow phenomenon easily generated by the camera in backlight scenes and shooting lights at night.

Mr. Ouyang Jian, deputy general manager of sitway, said: “5g promotes the rapid upgrading and development of video images. Imaging performance, as the main technical basis, penetrates into various application scenarios such as intelligent security and vehicle electronics, and continues to boost the development of intelligent video analysis technology. The two full series of upgraded products released by stevio this time are based on the latest dsi-2 technology, using stevio’s advanced chip design technology and innovative process The performance of dark light imaging, color expressiveness and noise control of the products are improved again, and strive to provide high-quality video image basis for current mainstream security surveillance cameras and high-definition driving image equipment. “

At present, sc2336 has achieved mass production, sc3336 has accepted sample delivery, and it is expected to achieve mass production in October 2021.
