SmartVision’s new Pro series CMOS image sensor with full performance upgrade for security applications
SmartVision (Shanghai) electronic Technology Co., Ltd. (stock abbreviation: SmartVision, stock code: 688213), officially launched three full-performance upgraded Pro series image sensors (hereinafter referred to as “P series”) products SC2336P for security applications , SC3336P and SC4336P. As a new product of SmartVision’s full-performance upgrade series, the P series products cover video solutions from 2MP to 4MP, built with advanced 12-inch wafer technology, and equipped with SmartVision’s innovative SFCPixel® patented technology and ultra-low noise peripheral reading Based on circuit technology, it has excellent performance in night vision full color, high temperature imaging and low power consumption, and strives to enable the intelligent development of security video applications with excellent high-performance imaging.
At present, the security industry is developing rapidly in the direction of digitization, intelligence, and ultra-high definition. In the future, the growth space of the entire intelligent security industry is quite broad. This also puts forward higher requirements for the imaging performance of security CMOS image sensors.
Upgraded DSI-2 technology for excellent low-light imaging and color performance
The new P series products released this time are based on SmartSens’ upgraded DSI-2 technology, equipped with SmartSens’ innovative SFCPixel® patented technology and ultra-low noise peripheral reading circuit technology, which has achieved a comprehensive improvement in imaging performance. By reducing the thickness of the inner dielectric layer, the new product makes the metal layer lighter and thinner, thereby improving the photosensitive performance in an all-round way. Taking SC4336P as an example, as a 2.0μm small pixel size sensor, its SNR1s is 18% lower than the previous generation product, and its sensitivity (A light) is greatly improved by 25%, which can be comparable to the industry 2.3μm pixel size sensor of the same specification Excellent low-light imaging performance, making dark details more clearly visible.
In addition, the new P-series products are equipped with SmartVision’s comprehensively optimized color technology and advanced Microlens new technology, and use the industry’s top materials to create Color Filter, which improves color reproduction and achieves imaging effects comparable to BSI technology. Compared with products of the same specification in the industry, the Chroma high and low color temperatures of SC4336P have been increased by 9% and 12% respectively, and the image picture is more gorgeous and undistorted.
Regardless of the harsh challenges of high temperature, the imaging performance is still outstanding
Security cameras need to deal with the high temperature working environment caused by long-term work in a limited space and outdoor exposure, and high temperature often degrades the image quality of the image sensor. SmartVision P series new products SC2336P, SC3336P and SC4336P have improved the imaging performance under high temperature through process optimization and upgrade. Taking SC4336P as an example, its Shading is lower than 3e- and DSNU is less than 0.8e-, which can eliminate the high temperature caused by high temperature. The imaging purple fringing phenomenon enables the camera to output high-quality images even in high temperature environments.
Lower power consumption, precise control design of on-chip modules
Thanks to SmartVision’s excellent low-power design, P series products can precisely control each module in the chip through configuration upgrades, thereby achieving excellent low-power performance. Taking SC4336P as an example, its power consumption is greatly reduced by 22% compared with the previous generation, which can help the battery life of emerging applications of smart security.
Mr. Ouyang Jian, Deputy General Manager of Smartway, said: “artificial intelligence is transforming the entire security industry from the inside out, giving birth to an emerging market worth hundreds of billions of dollars. Smartway has always kept close to the innovation driving force of market demand, and attached great importance to product performance and customers. Based on the upgraded DSI-2 technology, we have created a new full-performance upgraded Pro series image sensor for security applications. The launch of the P series products is the embodiment of Smartway’s determination to continue the full series of security products and the strength of technology research and development. This series of products has excellent low-light imaging performance, and further improves the imaging performance of the image sensor in terms of color rendering, high temperature adaptation, and low power consumption. It is bound to empower the smart security industry with better imaging quality. .”
At present, SmartVision SC2336P, SC3336P and SC4336P have all accepted samples, and it is expected to achieve mass production in Q4, 2022.
