July 23, 2025, Shanghai, China — SmartSens (Shanghai) Electronic Technology Co., Ltd. (stock name: SmartSens, stock code: 688213) recently announced the launch of a new 50-megapixel 1-inch high-end flagship mobile phone application image sensor - SC5A5XS. This new product is built on SmartSens SmartClarity-XL Pro technology, using 28+nm Stack advanced process technology, and equipped with SmartSens SuperPixGain HDRTM (single exposure three-frame fusion), SFCPixel-2 and AllPix ADAF and other advantageous technologies. As the first 1-inch full-process domestic mobile phone application CMOS image sensor equipped with SuperPixGain HDR technology, SC5A5XS has an ultra-high dynamic range of 110dB, ultra-high sensitivity, 100% full-pixel focus, ultra-low power consumption and other performance advantages, which will bring a leapfrog improvement in the imaging capabilities of flagship smartphone main cameras and help the professional development of mobile imaging to a new height.

SC5A5XS adopts the largest optical size of 1-inch CMOS image sensor in the current mobile phone application in the industry, with a large pixel size of 1.6μm and ultra-high photosensitivity. Its sensitivity is as high as 2569mV/lux*s, which is about 72% higher than the previous generation. The ultra-high sensitivity of SC5A5XS can bring super-sensitive imaging capabilities to flagship mobile phone cameras regardless of day or night, allowing wonderful photos to be taken in the dark night.

SC5A5XS is innovatively equipped with SuperPixGain HDRTM technology, with a dynamic range of up to 110dB, which is significantly improved compared with the previous generation products on the same process platform. Based on SuperPixGain HDRTM technology, SC5A5XS can help mobile phone cameras retain more bright and dark details in complex light scenes with strong light and dark contrast during video shooting, so that the bright parts are not overexposed, the dark parts are more delicate, and the backlit shooting is also vivid and clear.

SmartSens SuperPixGain HDRTM technology is achieved by three-frame fusion under the same exposure, which can effectively suppress the generation of motion artifacts while ensuring ultra-high dynamic range. Therefore, when shooting moving objects, SC5A5XS has obvious advantages over ordinary HDR mode products. Its video shooting effect is bright and dark, and the picture is clear without motion smear. In addition, SC5A5XS supports 4K 60fps ultra-high dynamic range high frame rate video recording in SuperPixGain HDRTM mode, which can provide more frame rate redundancy, giving flagship mobile phone cameras rich light and shadow levels and smooth professional-level video shooting capabilities.

Comprehensive improvement of key performance, extraordinary flagship imaging strength

SC5A5XS is a 50MP high-performance CMOS image sensor launched by SmartSens for flagship mobile phone main cameras, which has achieved comprehensive improvement of key imaging performance such as low noise, 100% full pixel focus and ultra-low power consumption. Thanks to SmartSens' patented SFCPixel-2 technology and excellent peripheral readout circuit design, the SC5A5XS has excellent low-noise performance, with a readout noise of <1e-, which can make the details of the picture cleaner and clearer in night scene shooting. In addition, the SC5A5XS supports the dual-mode adaptation of SmartSens' AllPix ADAF technology and Sparse PDAF technology. In low-light scenes, the SC5A5XS can use the AllPix ADAF mode to achieve 100% full-pixel focus, ensuring accurate and fast focus during night shooting. In addition, based on SmartSens' excellent low-power design, the SC5A5XS has excellent ultra-low power consumption performance in multiple modes. Compared with the previous generation products on the same platform, the power consumption is reduced by about 10%, which is conducive to improving the battery life of the mobile phone and greatly extending the continuous video shooting time.

Ma Weijian, co-founder and COO of SmartSens and CEO of High-Performance Perception BG, said: "With the continuous improvement of mobile phone imaging capabilities, we can see the trend of increasingly professional development of mobile imaging in video shooting. In the future, mobile phones will further replace some camera functions and take on the important task of taking both photos and high-quality videos. As a professional CMOS image sensor chip company, SmartSens has always attached great importance to the innovation and development of cutting-edge imaging technologies in the field of mobile phone imaging. SC5A5XS is the first 1-inch flagship mobile phone main camera CMOS image sensor equipped with SuperPixGain HDRTM technology launched by SmartSens based on a domestic supply chain. It has the largest optical size and the highest dynamic range of 110dB for mobile phone image sensors in the industry, and has been comprehensively upgraded in multiple key imaging dimensions such as sensitivity, focus speed, and low power consumption. The excellent comprehensive performance of SC5A5XS will provide strong support for the imaging specialization of flagship smartphones, significantly improving the light and shadow levels and picture quality of photos and videos, creating extraordinary imaging strength for high-end flagships, and promoting the development of mobile imaging to new heights."
