On June 19, 2025, Shanghai, China - SITWEI (Shanghai) Electronic Technology Co., Ltd. (stock abbreviation: SITWEI, stock code: 688213) recently announced the launch of the 50 megapixel 1/1.28-inch CMOS image sensor for mobile applications - SC595XS. The SC595XS is built on the advanced SmartClarity XL Pro technology from SITWEI, using a 22nm Stack advanced process technology and innovatively equipped with the SuperPixGain HDR from SITWEI? With multiple advantageous technologies such as single exposure three frame fusion, SFCPixel-2, and AllPix ADAF, it has an ultra-high dynamic range of 110dB and multiple performance advantages such as low noise, high frame rate, low power consumption, and 100% full pixel focusing. It can endow flagship smartphones with professional level imaging capabilities of vivid light and shadow and excellent picture quality, significantly improving the high dynamic video shooting effect of smartphones.

Ultra high dynamic range video with full control of light and shadow

Based on the SuperPixGain HDRTM technology from STMicroelectronics, the SC595XS achieves an ultra-high dynamic range of up to 110dB, which is significantly improved by about 22dB compared to its predecessor on the same platform. Therefore, the SC595XS can help mobile phone cameras capture more bright and dark details in environments with strong contrast and complex lighting conditions, reducing the occurrence of overexposure and loss of dark details in photos and videos, effectively solving the shooting difficulties of traditional pain points such as backlighting, local strong light, and interweaving of light and dark.

The SuperPixGain HDRTM technology is achieved through the fusion of three frames under a single exposure, ensuring ultra-high dynamic range while suppressing the generation of motion artifacts, resulting in clear and trailing photos and videos when capturing high-speed moving objects. Moreover, the SC595XS can support 4K 60fps SuperPixGain HDRTM ultra-high dynamic range video and 4K 120fps ultra-high frame rate video recording, which can bring vivid light and shadow, smooth and seamless professional video shooting effects to the camera, providing more frame rate redundancy for professional video creation.

Versatile flagship imaging chip for professional level imaging experience

As a 50 megapixel RGB image sensor, the SC595XS has a large pixel size of 1.22 μ m and excellent performance in multiple key image dimensions such as low noise, fast focusing, and low power consumption.

Based on the patented technology of STWE SFC Pixel-2, the SC595XS adopts a mid mounted SF design, which significantly reduces noise while improving sensitivity, making the imaging effect of smartphone cameras brighter, more delicate, and clearer in low light environments such as evening and night. And the SC595XS is equipped with Siwei AllPix ADAF and Sparse PDAF technologies, supporting dual-mode adaptive fast focusing. In low light scenes, AllPix ADAF mode can be turned on to achieve high-speed and accurate fast focusing effect through 100% full pixel focusing. In addition, thanks to the optimization of circuit and IP performance, the power consumption of SC595XS is significantly reduced compared to its predecessor on the same platform, which can effectively reduce device heating during high-definition video shooting and improve the overall battery life of the machine.

Ma Weijian, co-founder, COO, and CEO of High Performance Perception BG, said: "With the continuous upgrading and development of mobile imaging technology, smartphones have become the largest application device for daily image shooting, and are gradually replacing cameras to complete some more specialized shooting. Especially in the video industry, the rise of short videos in the era of self media has continuously increased the demand for video shooting applications on mobile phones. SC595XS is a new 50MP 1/1.28-inch flagship smartphone main camera CMOS image sensor launched by SITWEI based on the national production supply chain. It not only has multiple advantages such as low noise, 100% full pixel focusing, and low power consumption, but also innovatively equipped with SITWEI SuperPixGain HDR? The technology and dynamic range have reached the highest level of 110dB in the industry for mobile image sensors, and support 4K 60fps ultra-high dynamic range video recording in this mode. With its comprehensive upgrade and outstanding capabilities, the SC595XS can endow the smartphone's main camera with vivid light and shadow, realistic colors, and high-definition and delicate image texture, bringing professional level ultra-high dynamic range photo and video shooting experience to end users, making image creation more convenient and effortless. ”

SC595XS will receive samples in Q3 2025. If you want to learn more about SC595XS products, please contact the sales personnel of SITWEI.
