A team led by Prof. Tommy WEI Minchen, Management Committee Member of the Photonics Research Institute (PRI) and Professor in the Department of Building Environment and Energy Engineering (BEEE), has developed a series of colour management technologies that enable digital displays, imaging devices and extended reality (XR) to capture and reproduce colours more faithfully, thereby enhancing user experience. These cutting-edge technologies have been successfully commercialised and widely adopted by social media, imaging systems and manufacturers of LED lighting products, smartphones and drones. Over 100 million high-end smart devices worldwide are powered by the technologies every year.
The technologies include:
A six-channel RGBACL (Red, Green, Blue, Amber, Cyan and Lime) lighting module and control algorithm
Aiming to enhancing the colour presentation of LED lighting systems, the algorithm can quickly adjust the colour appearance of human facial skin captured by different cameras. This technology has been used by a famous manufacturer of cinema lighting fixtures and in the production of several Hollywood movies and TV series.
Solutions for capturing and displaying colours on video and image shooting equipment
These include the use of artificial intelligence (AI) technology to detect human faces in the frame and to optimise the colour appearance of skin.
Chips with built-in AI-powered white balance algorithm
These technologies ensure more faithful colours in photos and videos taken with digital cameras under different environments. They have been adopted by world-class smartphone and XR device manufacturers.
Other related solutions
These include technologies for colour processing of images dominated by a single colour in telephoto and macro shooting; colour tuning during image processing; colour capture and reproduction of high dynamic range (HDR) scenes; and ensuring the colour consistency of displays used in various devices, as well as a self-adjusting colour algorithm for mixed-reality headsets.
