Abstract
The purpose of this study is to examine gray matching between dark and ambient condition and to improve visibility using result of gray matching experiment in mobile display and target luminance is 30000 lux for experiment. First of all, for measuring visibility on ambient condition, the patch count experiment is conducted by investigating that how many patches can be seen at original images under the ambient light. The visibility in ambient condition was significant in comparison to dark condition. Next, the gray matching experiment is conducted by comparing gray patches between dark and ambient condition using method of adjustment. The participants responded that the white or bright gray patch could not find same brightness patch under ambient condition. To confirm the visibility improvement through the result of gray matching experiment, visibility is measured under the ambient light after simple implementation. It was same procedure of the first visibility experiment. After applying the gray matching curve, visibility was more improvement. Statistic T test result between patches applied gray curve and maximum of dark condition was not significant. It means that visibility was not different between original patches of dark condition and patches applied curve of ambient condition.
