Display method and display apparatus

摘要

The display method and apparatus display colors used in color information on a display unit capable of displaying gray scale. The method and apparatus convert the colors into gray scale values so as to enable differences in the colors to be identified even when the colors are displayed based on the gray scale on the display unit, and then display the color information on the display unit by utilizing the converted gray scale values as the colors. The method and apparatus can recognize meaning of the differences in original colors even in the case of displaying color information on a monochrome display (the display unit capable of displaying the gray scale).
