Abstract (in Japanese) (See Japanese page) 
(in English) Many image processing methods have been studied by which color defectives can recognize differences of colors that originally they cannot. There are several strategies to achieve this purpose. One is to change color itself to recognizable ones, and another is to use image textures to show color difference. In this report, we propose a method indicating the color difference by blinking image pixels. The strength of blinking depends on the position of the object color on the confusion line, from which the color defectives can recognize level of the difference. As practical applications of the proposed method, we show a process to show grilling level of beef and ripeness level of tomatoes. The changes of spectral reflectances of beef and tomatoes were measured by a spectral luminance meter, and based upon them, we set appropriate parameters for blinking image pixels.
