<p>PURPOSE:To prevent the disappearance of a display even when the speed of a cursor movement is fast and to prevent the losing sight of the cursor by an operator. CONSTITUTION:Plural XY registers R1, R2 and R3 for specifying a position for displaying the cursor and XY coordinate comparators C1, C2 and C3 for comparing positions specified by these registers and display control positions on a display device are prepared. Then, the cursor is displayed in sequence by any one of the plural XY registers R1, R2 and R3 and the XY coordinate comparators C1, C2 and C3 in accordance with the display control of the display device. Thus, a remaining image immediately before the movement of the cursor moving in accordance with the movement of the cursor is displayed. Therefore, when the cursor is displayed on a liquid crystal display, etc., whose display response time is long, the cursor during the movement is displayed as a remaining image even when a mouse, etc., is moved fast.</p> |
