Visual Perception Is The Core Entrance To Information Acquisition And ISP Is The Key
Visual perception is the entrance to information acquisition in the digital age. ISP (Image Signal Processor), as the core technology of visual perception, is the key for smart terminals to go from "seeing the world", "seeing the world clearly" to "understanding the world". ISP processes the light information received by the optical lens into image information, and optimizes the image noise, brightness, chromaticity, etc. through a series of digital image processing algorithms, so that smart terminals have "smart eyes" to see the world.
Visual Perception Environment Is Complex And Changeable ISP Imaging Quality Faces Challenges
Visual perception scenes are diverse and light changes are complex, such as tunnel or basement entrances, bad weather, underground mining, etc., and a large amount of valuable image information is collected in low light, weak light, backlight, backlight, rain, snow, fog and strong wind. The image quality is greatly affected by low light and bad environment.
Visual perception must break through the limitations of time and external environment and weather, and provide 7*24 hours all-weather, full-scene ultra-high-definition images.

Traditional ISPs Have Reached Their Limits AI ISPs Break Through Bottlenecks
Faced with increasingly complex scenes and higher image quality requirements, traditional ISP image processing technology has reached a bottleneck. As the parameter library becomes increasingly large, debugging becomes more difficult, the development cycle gradually lengthens, and the return on investment for image quality improvement becomes lower and lower. At this time, the deep integration of image quality technology and AI technology is crucial. Using AI computing power to deeply learn massive scenes and data, intelligently tune complex parameters, and output algorithm models to assist image processing, the image quality breaks through the limits of traditional ISP.

Multi-spectral Fusion
Hardware Acceleration Low-light Full-color
HiSilicon's multi-spectral fusion technology uses infrared fill light to fuse common spectra such as visible light, 850nm, and 940nm in the ISP. Even in low-light, weak-light, or even dark environments, the image effect can reach full color in low light without increasing light pollution, fully showing the power of every ray of light. The city scene at night, the hustle and bustle under the street lights, and the twilight of the setting sun are all clear frame by frame under the camera powered by HiSilicon chips, with rich details and textures, and true colors.
Super Wide Dynamic
Dynamic Range Increased By 12DB
HiSilicon's super wide dynamic technology can perform scene recognition and adaptive multiple exposures based on value targets. It fuses the image data of long frames, medium frames, and short frames with different exposure times through intelligent algorithms. The data width after fusion is 20 bits, and the dynamic range is improved by 12dB compared with the first generation, so that the image can achieve perfect integration of dark and bright areas, without overexposure of bright areas and loss of details in dark areas. The backlit scenes are clear and the dark scenes are colorful, so that visual perception is no longer afraid of backlight. At the same time, based on the intelligent exposure technology of scene recognition, the target area can be accurately and quickly identified in scenes with rapidly changing light to avoid the loss of key information of value targets.
