Abstract

The color compensation method, which recovers the color perception of elderly people making similar to the one of young people, entirely amplifies color signals to compensate lenticular yellowing and pupil diameter reduction by aging. Thus, the color signals in the original image sometimes exceeds the range (0〜255) of RGB color system, which causes undesirable effect on the output (corrected) image by rounding operation of such pixels into the displayable range. From this point of view, in this work, we examine which color exceeds the displayable range and how the color distribution of the input image affects on the output image in this color compensation method by using 464 colors in the data set and several natural images.
