摘要 |
Detailed information about plural factors determining a color and the coordinate value of a pointed position are determined from a position pointing device. The detailed information about the plural colors is by factors such as detailed gradation information on basic colors such as red, green, and blue. The amplitude or frequency of an AC field is controlled in accordance with the set color information. The AC field has a spatial distribution corresponding to the coordinate value of the pointed position.
