Professor Wei Minchen Tommy Leads Team in Developing Cutting-Edge Colour Management Technologies for Digital Devices

The Department of Building Environment and Energy Engineering (BEEE) at The Hong Kong Polytechnic University (PolyU) is proud to announce the remarkable achievements of Professor Wei Minchen Tommy, Professor of BEEE and Director of the Colour Imaging and Metaverse Research Centre at PolyU. Prof. Wei and his research team have successfully developed a series of groundbreaking colour management technologies that significantly enhance the accuracy and reproduction of colours in digital displays and imaging devices.

Prof. Wei's pioneering research addresses the challenges posed by emerging technologies such as OLED and Quantum-dot LED (QLED), which have narrower spectral compositions, making it difficult for cameras and displays to capture and reproduce consistent colour appearance. The following are some of the remarkable technologies developed by Prof. Wei and his team:

1. RGBACL Lighting Module: A six-channel RGBACL (Red, Green, Blue, Amber, Cyan, and Lime) lighting module and control algorithm that enhances the colour presentation of LED lighting systems. This technology has been widely adopted in the cinema industry, including the production of Hollywood movies and TV series.
2. AI-Powered Colour Optimisation: Various solutions that employ artificial intelligence (AI) technology to detect human faces in video and image shooting equipment, optimizing the colour appearance of skin tones.
3. AI-Enabled White Balance Algorithm: Chips integrated with an AI-powered white balance algorithm, ensuring more faithful colours in photos and videos taken by digital cameras under different environmental conditions. These technologies have been adopted by leading smartphone and extended reality (XR) device manufacturers.

Prof. Wei's contributions to the field of colour science have garnered recognition and funding from prestigious organizations such as the Research Grants Council, the National Natural Science Foundation of China, and the Electrical and Mechanical Services Department in Hong Kong. He has received several awards, including the Google Research Scholar Award, the PolyU Young Innovative Researcher Award, and the PolyU President's Award for Outstanding Achievement in Knowledge Transfer.

To further advance the application of their research outcomes, Prof. Wei co-founded Guardian Glow Limited, a startup focusing on personalised AI smart devices and XR headset technologies. The company has attracted support from venture capital funds and private investors to continue developing user experience-enhancing colour management technologies.

Prof. Wei and his research team at PolyU have achieved groundbreaking advancements in colour management technologies for digital devices. Their innovations have revolutionized the accuracy and reproduction of colours, benefiting industries such as cinema, social media, and smartphone manufacturing. The Department applauds Prof. Wei's exceptional contributions to scientific research and knowledge transfer, driving the field of colour science to new frontiers in the digital era.
