This study investigates the effects of the size and the luminance value of the surround field on colour appearance under various viewing conditions. Ten phases of psychophysical experiments were conducted to obtain visual data assessed by a panel of 10-15 observers. The viewing conditions investigated include two sizes of surround field, three viewing distances, two luminance values of surround and three different sizes of stimuli. The accumulated visual data sets were used to test the CIE colour appearance model, CIECAM02, and the results showed that CIECAM02 gave a satisfactory prediction. Finally, the viewing parameters F, Nc and c in CIECAM02 were optimised to fit colour appearance results under different surround conditions. It was found a very small improvement.

More about this publication?
  • Started in 2002 and merged with the Color and Imaging Conference (CIC) in 2014, CGIV covered a wide range of topics related to colour and visual information, including color science, computational color, color in computer graphics, color reproduction, volor vision/psychophysics, color image quality, color image processing, and multispectral color science. Drawing papers from researchers, scientists, and engineers worldwide, DGIV offered attendees a unique experience to share with colleagues in industry and academic, and on national and international standards committees. Held every year in Europe, DGIV papers were more academic in their focus and had high student participation rates.
