Honor Magic 6 Ultimate Edition makes its global debut! Official popular science LOFIC technology

According to news on March 13, Honor Li Kun announced that Honor Magic6 Ultimate Edition and Honor Magic6 RSR Porsche Design will launch the SLR-level super dynamic Eagle Eye camera based on LOFIC technology.

It is reported that the full name of LOFIC technology is Lateral OverFlow Integration Capacitor. The basic principle of LOFIC technology is to place a high-density capacitor on each photodiode of the mobile phone image sensor to collect data that may otherwise be caused by saturation. And the overflowing photoelectrons.

In this way, when the number of photoelectrons converted by the photodiode exceeds the maximum capacity it can originally carry, the excess photoelectrons will flow into the adjacent capacitor,

Instead of being "overexposed" due to overflow, the highlight information in the shooting scene is better retained by the sensor, making the output film closer to the real light and shadow scene.

From a data point of view, Honor, the industry's first image sensor based on LOFIC technology, directly significantly increases the single-pixel full well capacity of 30,000 of traditional mobile phone image sensors by 9 times reached about 270,000, which greatly improved the light tolerance of the image sensor for extremely large light ratio scenes.

At the same time, this image sensor also achieves a SLR-level ultra-high dynamic range of 15EV, which is more than 3 stops higher than traditional mobile phone image sensors. The theoretical dynamic range is even equivalent to SONY's mirrorless video flagship A7S3.

The higher dynamic range allows the mobile phone to better capture and retain the details of highlight and dark areas, avoiding the problem of overexposure or underexposure. Bright places can be brightened, and dark places can be brightened. Can see clearly, achieving an actual experience closer to the human eye.

LOFIC technology was the first to be applied to in-vehicle camera systems for autonomous driving in the automotive industry. Because in-vehicle camera systems often need to face extremely dynamic scenes, such as crossing tunnels, entering and exiting parking lots, night scenes, etc., therefore The need to capture large light is more comprehensive and prominent than the ability of scene images.

Honor has seen this, so it hopes to apply this technology to the imaging system of mobile phones, get rid of the inherent practice of blindly increasing the sensor area, and find another way to use more advanced technology to solve the problem. The problem of limited dynamic range of mobile phone image sensors.

But bringing LOFIC technology to image sensors for mobile phones is not a simple matter. For example, how to implant high-density capacitors into small pixels suitable for mobile phones, and how the back-end LOFIC technology brings How to process and use the ultra-high dynamic range information are new problems we encounter.

Faced with these challenges, Honor has fully demonstrated the technical feasibility two years ago, and opened up a high-dynamic path for image reception, fusion, conversion, and display during system design. Only then can the high-latitude advantages brought by LOFIC technology be fully utilized, and finally the new Honor Magic6 series products equipped with LOFIC technology can more easily cope with and present the excellent effects of ultra-high dynamic imaging.
