Investigation of Large Display Color Image Appearance II: The Influence of Surround Conditions
Abstract:The purpose of this work was to quantify the surround effect on the color image appearance of images presented on a large display. The appearance attributes colorfulness, contrast, and naturalness together with image quality were estimated under four surround conditions: Dark, dim, and bright surrounds (all excluding veiling glare), and a typical office environment (including veiling glare). The most interesting visual result was that the three illuminated surrounds caused dark images to have a reduction in all of the image appearances studied, compared with those under dark surrounds. Enhanced contrast, naturalness, and quality were perceived in dark surround conditions, whereas the most colorful appearance was seen with bright surrounds. The most critical attribute affecting image quality in all surrounds was naturalness. Empirical models were developed which took into account the significant visual phenomena revealed in this study to predict the effect of surround on the appearance of color images.
