Abstract
A color perception test has a color matching processor that executes a color matching processing on a color monitor, and an image display controller that displays two or more images for color perception test in order on the color monitor on which the color matching processing was done. When displaying each image for color perception test, a color perception test is done in a state that one of its hue, brightness, saturation and display time is changed and the other elements are fixed. Since the color perception tester has the color matching processor, colors of the image are not changed with passage of time different from color printed one, and correct test can be done thereby. If the test is periodically done on some examinee, a degree of decreasing color perception function by aging can be exactly known.
