<P>PROBLEM TO BE SOLVED: To improve image identification properties for a color-blind person. <P>SOLUTION: On the basis of color conversion information where colors difficult for a color-blind person to identify and colors easy for them to identify are associated with each other, the colors difficult to identify in an input image are converted to corresponding colors easy to identify to output a color conversion image. Then, the contour of color conversion image is extracted, the brightness of an input image or a color conversion image is calculated, and the color of contour of color conversion image is converted so that the difference between the brightness of contour of color conversion image and the brightness of the input image or the color conversion image is equal to or more than a predetermined value. <P>COPYRIGHT: (C)2013,JPO&INPIT |
