<p>PURPOSE:To keep the locus of a mouse cursor and to recognize the position of the mouse cursor by displaying the residual image of the mouse cursor for a fixed time even though the mouse cursor is moved at a high speed on a liquid crystal display. CONSTITUTION:In a computor comprising mouse controller 1, a main CPU 2, a CRT controller 3, and a graphic RAM 4, the controller 1 controls the movement of a mouse cursor and also controls the residual image of the mouse cursor based on a compiled residual image program. Thus the residual image is left on the locus of the mouse cursor for a fixed time and at a fixed interval. Thus, the position of the mouse cursor is satisfactorily recognized even though the mouse cursor is moved at a high speed on a liquid crystal display, for example, that has a low response speed.</p> |
