The first problem is that in the conventional mouse cursor display device, it may take some time to find the mouse cursor when the screen resolution is high.

The reason is that the conventional mouse cursor display device displays the mouse cursor with a fixed number of dots regardless of the screen resolution, so that the mouse cursor is displayed in a sufficient size on a screen with a low resolution. However, the higher the resolution, the smaller the mouse cursor is displayed.

The second problem is that if the mouse cursor is displayed in a large size, the mouse cursor can be easily searched for even if the screen resolution is high, but there is a problem that it becomes an obstacle when viewing other screen information. .

The reason is that when the mouse cursor is displayed large, other screen information is hidden by the mouse cursor.

_{An object of} the _{present invention is to} display a mouse cursor displayed vertically and horizontally by enlarging it by Y times and X times when a mouse movement event does not occur within a fixed time (L seconds). When a mouse movement event occurs in the mouse or when a certain time (M seconds) has elapsed, the mouse cursor is returned to its original size, so that the mouse cursor position can be displayed without obscuring other screen information even when the screen resolution is high. Make it easy to understand
_{To provide a mouse cursor display device that can

[0011]

The mouse cursor display device according to the present invention is a mouse for changing from the mouse cursor original size mode to the mouse cursor enlargement mode when a mouse movement event does not occur _within a _{predetermined time} while the mouse cursor is being displayed. In the event monitoring unit ₍ 1 ₎ and mouse cursor expansion mode, the mouse cursor bitmap is vertically and horizontally multiplied by Y and X respectively.
Mouse Casa enlarged portion making bitmap enlarged doubled (2) and _the said mouth Casa enlarged portion erase the bit map of the mouse Casa being displayed mouse Casa enlarged portion (2) is passed bitmap (2 ) And a mouse cursor display section (3) for displaying the bit map passed from (1).

The mouse event monitoring unit (1) may be configured to transition to the mouse cursor full-scale mode when an event of mouse cursor movement occurs in the mouse cursor expansion mode or when a _{predetermined time} elapses.

The mouse cursor enlarging section (2) may generate a bitmap in which the bitmap of the mouse cursor is reduced to the actual size when transitioning from the mouse cursor enlarging mode to the mouse cursor original size mode.

When the mouse event monitoring unit detects that the mouse movement event does not occur within a fixed time,
The mouse cursor enlargement unit enlarges the mouse cursor bitmap vertically and horizontally by Y times and X times, respectively, and the mouse cursor display unit displays the bitmap. Therefore, even if the screen resolution is high, it is easy to understand where the mouse cursor is on the screen.

When the mouse cursor monitoring unit detects the occurrence of a mouse movement event or detects that a certain time has elapsed, the mouse cursor expansion unit creates a bitmap in which the mouse cursor is returned to its original size, and the bitmap is created. The mouse cursor display is displayed. Therefore, even when the screen resolution is high, it is possible to easily understand where the mouse cursor is on the screen without obscuring other screen information.
