(A) Color and illumination technologies

  • Total color appearance system for photopic, mesopic and scotopic viewing conditions in either real or virtual spaces
  • High dynamic range imaging and its color management techniques
  • Psychophysical models of color emotion and color conspicuity
  • Psychophysical models of color harmony and visual comfort for various applications such as visual communication design, fashion design and interior lighting design
  • Color vision models for 2D and 3D images that are either static or dynamic
  • 3D-printing-integrated color appearance reproduction, including highly accurate simulation of color appearance of objects, standard material data development and object appearance reproduction
  • Methods of visual assessment of image quality for 2D and 3D images
  • Developing psychophysical models of image quality for 2D and 3D images
  • Influences of 3D images on health and security
  • Developing systems for accurate appearance simulation
  • Measurement and evaluation of white and chromatic light sources
  • LED lighting design for interior and exterior spaces
  • Special LED light sources for improving work performance and health enhancing
  • Developing LED light sources of high color rendition and energy saving


We are also developing highly potential products, including:

  • Display systems for enhancing image quality such as TV displays, mobile devices, projectors and e-books
  • Measuring and simulation systems for appearance of 2D or 3D objects, including color, gloss, transparency, translucency and texture
  • Psychophysical analysis systems for lighting based on short-term and long-term data for various lit environments
  • Affective lighting systems for enhancing the user’s emotion and work performance
  • Lighting and display systems for older people and people with low vision
  • Applications of medical imaging for enhancing color reproduction
  • High-speed and high-precision 3D scanning system that provides a faster and simpler approach to collection of 3D data for highly customizable products and data analysis for areas such as customized shoes, 3D online testing and digital dentists
