If you often shop online, you must be familiar with one of the product descriptions: "Reminder: Due to factors such as shooting light and display, it is impossible to avoid the color difference in the product image. Please refer to the actual product received."

In the digital age, pictures and videos are replacing words as the main way people record and share; screens are also replacing paper and become the main medium for people to obtain information. As a result, people surrounded by digital images are becoming more and more intolerant of "chromatic aberration"——

Obviously, the design drawings on the computer are blue, so how come it looks purple when replaced with a mobile phone? Obviously I bought a pair of gray pants on my mobile phone. How come they are green when I get them?

Recently, after rigorous theoretical derivation and experimental verification, the chief scientist and Qiu Min team of our company, with the cooperation of Zhejiang Light Cone Technology Co., Ltd., finally proposed a complete set of digital color coding and decoding algorithms based on CIE color space. Published the latest research results titled "Nonlinear Color Space Coded by Additive Digital Pulse" in the international optical journal "Optica". They proposed to use the color space based on human eye perception instead of the color space based on the physical device itself to solve the problem of color distortion in the process of preservation and reproduction.

In other words, they gave the color a new set of "codes"-not only can resolve the color difference between different displays to the greatest extent, but also solve the "color difference" between the color seen by the human eye and the machine display. "Seeing is believing."

"The greatest significance of this research is that it is both interesting and useful." Professor Qiu described the future with CIE as the key word for us:

We will use CIE photodetector-based cameras or mobile phones to record moments in life. The captured images are automatically stored as a picture file with a suffix of CIE format. In the future, we can use CIE mobile phones or CIE monitors to relive the recorded beautiful moments. The image captured with the eyes at first, after shooting, imaging, and multi-screen display, everything is still perfectly reproduced.

For both academia and industry, this may bring about a change.
