Paper Abstract

The following three visual phenomena have been confirmed as a visual effect occurring at an edge having a density change: (a) Mach band, (b) Chevreul illusion, and (c) the Craik-O'Brien-Cornsweet effect. These are considered to be different phenomena. In our previous research, it was found that by varying the blurred edge width the density value of the image changed and the contrast decreased approximately by 20% at the maximum. From this phenomenon, it was possible to explain to some extent the relevance of the above three phenomena by the edge width. Furthermore, under the research of gazing time and edge blurring phenomenon, we confirmed that edges disappear with low contrast. In this paper, we focus attention on the gazing time and conduct an evaluation experiment on how much the Troxler effect occurs, using the density difference of the presented image as a parameter. We also investigate the evaluation of the Mach band at that time. Through these experiments, it is possible to show the experimental results that clarify the relationship between the four phenomena.
