This paper reveals one of the advantages of using multiprimary display, which can utilize the degrees of freedom. A spectral-approximation method, which was already proposed, is one of the methods concerning this advantage. This method is based on minimizing the difference between the spectrum of the original object and the reproduced spectrum under the constraint of tristimulus match for the CIE standard observer. We can expect some reduction of the color mismatch for any CMF. However, visual evaluation for actual images has not been reported until now. Therefore, we made a visual experiment to evaluate the spectral-approximation method using actual images, which contain many colors and shadings. We also present a novel algorithm for the spectral-approximation method.

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.
