LEDSimulator Technology: A Research Tool for Colour and Texture

This paper describes LEDSimulator, a system that exhibits the impact of texture on colour appearance and serves as a colour communication tool for supply chain management. LEDSimulator is capable of accurately displaying coloured textures, achieving successful colour reproduction between media, and expediting the production cycle. The key technologies that accomplish this are introduced here, including: 1) visual colour matching on textures, 2) projector characterization modeling using the conventional and an advanced reduced LUT approach, and 3) a model to achieve metameric cross-media reproduction.
