Color perception tester, control program and method of controlling color perception tester
First Claim
1. A color perception tester, comprising:
- a color matching processor that executes a color matching processing on a color monitor;
an image display controller that executes at least one display step wherein two or more images for color perception test are displayed in order on said color monitor on which said color matching processing was done;
whereby said image display controller changes display time of each image for color perception test so as to become gradually longer as a first element, or changes one element of five elements, of;
a hue, a brightness, a saturation of each image for color perception test, and a brightness of a background image in an optional color or a stimulus if said images for color perception test are comprised of said background image and said stimulus shown in said background image as said first element in such a state that said display time is fixed when displaying said two or more images for color perception test in said one display stepwherein said image display controller executes at least two display steps, a first display step wherein two or more images for color perception test are displayed in order on said color monitor on which said color matching processing was done, and a second display step wherein two or more images for color perception test are displayed in order on said color monitor, andsaid image display controller changes said first element when displaying each image for color perception test in each display step, and changes a second element, excluding said first element of six elements of;
hue, brightness, saturation and display time of each image for color perception test and brightness of a background image in an optional color or a stimulus if said images for color perception test are comprised of said background image and said stimulus shown in said background image gradually in said first display step and said second display step and fixes four elements excluding said first element and said second element during said first display step and said second display step.

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.
