Development of Smart Phone Application Image Processing that Makes it Easly to Distinguish the Color of Grilled Meat for Color Vision Diversity

Abstract

Many people can distinguish whether the meat is grilled or not by the color of the meat. People with dichromacy, however, are hard to do this. Such characteristic in which the color seen by a human looks different is called color vision diversity. In this paper, we propose a smartphone application for color vision diversity in which we can easily judge the degree of grilled meat. This application obtains the image of the meat by a camera of the smartphone, and modifies the color of the raw meat. We investigated five methods of the modification. We conducted experiments to evaluate the application. We presented 90 images of grilled or raw meat to 37 subjects by changing the modification method. Each subject answered the meat presented is grilled or not. As a result of the experiments, the method adding blue color to the raw meat and changing raw meat to the yellow-blue lattice pattern are effective to reduce the misjudgement that raw meat is roasted.
