As shown in FIG. 6, the composition unit 305 detects a pen-up (end of pen writing) of the first or second input device 102, 150, and then a predetermined time after the pen-up time elapses. The color vision barrier confirmation window A2 reflecting the drawing contents may be displayed in a composite manner. For example, in FIG. 4, when a descriptor (color vision normal person) inputs “180 °” with the first or second input device 102, a color vision barrier confirmation window is displayed for a certain period after 180 ° is input. A2 is synthesized and displayed.

  Note that the color vision barrier confirmation window A2 may be switched between the first color blindness, the second color blindness, and the third color blindness during the display for a certain period of time. This makes many color blind people barrier-free. The color vision barrier confirmation window A2 for each of the first color blindness, the second color blindness, and the third color blindness may be displayed at a time. The color vision barrier confirmation small window A2 may be realized by a screen list display (thumbnail display) function.

  According to the first embodiment, the color display data creation unit 301 creates color display data, and the pseudo color vision conversion unit 303 causes the color blind person to color sense the color display data input by the color display data creation unit 301. The color vision barrier confirmation window creation unit 304 creates a color vision barrier confirmation window A2 of the color display data subjected to the pseudo color vision conversion, and the synthesis unit 305 receives the color display data creation unit 301 from the color display data creation unit 301. The input color display data and the color vision barrier confirmation window A2 created by the color vision barrier confirmation window creation unit 304 are synthesized, and the synthesized synthesized display data is displayed on the display screen of the display device 100 via the drawing device 400. Therefore, a person with normal color vision can recognize how a person with color blindness looks, Ordinary person is as refrain from the use of the color display data of the color scheme that difficult to see in color vision disabilities, it is possible to perform the easy-to-read color display for color vision disabilities.

  In addition, since the synthesis unit 305 displays the color vision barrier confirmation window on the display screen of the display device 100 for a certain period of time, the display of the color vision barrier confirmation window A2 can be prevented from becoming an obstacle. .
