초록

색각 이상자들은 채도와 명도가 낮은 색채들에 대해 분별력을 갖지 못할 뿐 아니라 감성 왜곡과 관련하여 부정적인 감성을 표출한다. 감성의 기본이 되는 감각에 대한 왜곡을 바로 잡고자 함은 색각이상자들이 디지털 문화콘텐츠에 접할 때 느끼는 부정적인 감성보다 긍정적인 감성을 높이기 위해서이다. 대비는 채도와 명도간의 변환되는 방향이 다르게 하여 높이고, 이를 통해 원본 이미지가 전달하는 동적과 정적, 선명함과 칙칙함이라는 감각 왜곡을 감소시켜 색각 이상자에게 전달한다. 이를 색변환이 이뤄지는 영역에 대하여 채도와 명도를 변환하는 대비기반 색변환 방법을 제안하고 이 방법이 감각 왜곡을 감소시킨다는 것을 색변환 시뮬레이션과 사용자 테스트를 사용하여 확인한다.

Color deficient people do not have sufficient discernment for the colors with low saturation and brightness and at the same time express their negative emotions regarding emotion distortion. The purpose of recovering the distortion of the vision which is the basis for emotion is to increase positive emotions rather than negative ones that those with color vision deficiency feel when they experience digital culture contents. Contrast increases saturation and brightness by differing the direction of their conversion and by doing so, delivers emotion distortion such as dynamic vs. static and vivid vs. somber that the original images intend to convey to those with color vision deficiency by reducing such a contrast. In this respect, this study proposes a contrast-based color conversion method to convert saturation and brightness in the zone of color conversion and identifies if this method can reduce emotion distortion by using color conversion simulation and user test.
