ABSTRACT:
When an application program is being executed, a popup menu screen is displayed on a display device in response to a depression of specific keys on a keyboard. The popup menu screen displays a plurality of types of data indicating gray scale levels. A user selects one of the data indicating gray scale levels. Gray scale data are set in pallet registers in a display controller on the basis of the selected data indicating the gray scale level. As a result, a screen display based on the selected gray scale levels can be obtained in real time.
