Honor Magic6 series debuts LOFIC technology: a new chapter in dynamic range for mobile photography

Honor Li Kun recently announced that the upcoming Honor Magic6 Ultimate Edition and Honor Magic6 RSR Porsche Design will be equipped with LOFIC technology for the first time and equipped with SLR-level super dynamic Eagle Eye cameras. This innovative technology is expected to bring a qualitative leap to mobile photography and lead a new trend in photography experience.

LOFIC technology, the full name is Lateral OverFlow Integration Capacitor, that is, lateral overflow integrating capacitor technology. The core principle of this technology is to add a high-density capacitor next to each photodiode of the mobile phone image sensor to capture those photoelectrons that may overflow due to saturation. When the number of photoelectrons converted by the photodiode exceeds its carrying capacity, the excess photoelectrons will be directed to the adjacent capacitor, thereby avoiding "overexposure" caused by overflow. This innovative design allows the highlight area information in the shooting scene to be better preserved, thereby making the final photo effect closer to the realistic light and shadow scene.

# According to the editor’s understanding, the image sensor based on LOFIC technology launched by Honor this time has achieved a qualitative leap in performance. Its single-pixel full well capacity has been significantly increased from 30,000 of traditional mobile phone image sensors to 270,000. This jump not only greatly enhances the sensor's light tolerance for high dynamic range scenes, but also achieves 15EV ultra-high dynamic range comparable to SLR cameras. scope. Compared with traditional mobile phone image sensors, its dynamic range has been improved by more than 3 stops, and is even theoretically equivalent to the dynamic range of SONY's mirrorless video flagship A7S3. This means that whether in high-brightness or high-dark areas, the new Honor Magic6 series can capture and retain details more accurately, thereby avoiding the problem of overexposure or underexposure, and making the photo effect closer to the actual experience of the human eye.

#LOFIC technology was originally used in vehicle camera systems for autonomous driving in the automotive industry. Since the vehicle-mounted camera system needs to face a variety of extremely dynamic scenes, such as crossing tunnels, entering and exiting parking lots, and night scenes, the camera system is required to have excellent capabilities in capturing images of scenes with large light ratios. Honor saw the huge potential of this technology and decided to introduce it into the imaging system of mobile phones in order to solve the problem of limited dynamic range of mobile phone image sensors. However, applying LOFIC technology to mobile phone image sensors is not easy. After two years of hard work, the Honor team has overcome many technical problems, such as the implantation of high-density capacitors and the processing and use of ultra-high dynamic range information at the back end. In the end, they successfully opened up a high-dynamic path for image reception, fusion, conversion, and display, giving full play to the high-tolerance advantages of LOFIC technology.
