Abstract

We have investigated the image quality attribute due to the wide color gamut by comparing it with the conventional sRGB color gamut. The results from the comparison between the two displays showed that 93% of the selected images appeared to have more 'Sharpness' when displayed on the wide gamut display. Previous studies on wide gamut displays were mainly focused on how natural it looked with the color gamut covering the real object color gamut. However we found that the prior image quality attribute for wider color gamut is sharpness caused by chroma contrast. Therefore Sharpness is the main image quality attribute for wide color gamut displays and could be the main factor in image quality improvement.
