ELECTRONIC DEVICE AND POINTING DEVICE CONTROL METHOD

1 . An electronic device comprising:

an input configured to receive operation information corresponding to an operation of a pointing device;

an output configured to output an image to be displayed on a display; and

a controller configured to:

set a plurality of divisional areas on a screen of the display in accordance with a resolution of the display, and

move a mouse pointer in units of a divisional area of the plurality of divisional areas in accordance with the operation information.

2 . The electronic device of claim 1 , wherein the controller is further configured to set the plurality of divisional areas, based on data indicative of an enlargement ratio of an object displayed on the display.

3 . The electronic device of claim 2 , wherein the controller is further configured to:

determine whether setup of the plurality of divisional areas is enabled, based on the resolution and the enlargement ratio; and

set the plurality of divisional areas when the setup is enabled.

4 . The electronic device of claim 2 , wherein the controller is further configured to:

calculate a division number of the plurality of divisional areas, based on the resolution and the enlargement ratio; and

set the plurality of divisional areas in accordance with the division number.

5 . The electronic device of claim 1 , wherein the controller is further configured to make a speed for moving the mouse pointer in units of the divisional area to be higher than a speed for moving the mouse pointer in accordance with the operation information before setting the plurality of divisional areas.

6 . The electronic device of claim 1 , wherein the controller is further configured to:

determine a divisional area of the plurality of divisional areas that includes a destination of movement of the mouse pointer corresponding to the operation information; and

display the mouse pointer at a position in the determined divisional area.

7 . A pointing device control method comprising:

receiving operation information corresponding to an operation of a pointing device;

setting a plurality of divisional areas on a screen of a display in accordance with a resolution of the display; and

moving a mouse pointer in units of a divisional area of the plurality of divisional areas in accordance with the operation information.

8 . The pointing device control method of claim 7 , further comprising setting the plurality of divisional areas, based on data indicative of an enlargement ratio of an object displayed on the display.

9 . The pointing device control method of claim 8 , further comprising determining whether setup of the divisional areas is enabled, based on the resolution and the enlargement ratio,

wherein the plurality of divisional areas are set when the setup is enabled.

10 . The pointing device control method of claim 8 , further comprising calculating a division number of the plurality of divisional areas, based on the resolution and the enlargement ratio,

wherein the plurality of divisional areas are set in accordance with the division number.

11 . The pointing device control method of claim 7 , wherein when the mouse pointer is moved in units of the divisional area, a speed for moving the mouse pointer is made to be higher than a speed for moving the mouse pointer in accordance with the operation information before setting the plurality of divisional areas.

12 . A computer-readable, non-transitory storage medium having stored thereon a computer program which is executable by a computer, the computer program controlling the computer to execute functions of:

receiving operation information corresponding to an operation of a pointing device;

setting a plurality of divisional areas on a screen of a display in accordance with a resolution of the display; and

moving a mouse pointer in units of a divisional area of the plurality of divisional areas in accordance with the operation information.

13 . The storage medium of claim 12 , wherein the computer program further controls the computer to execute a function of setting the plurality of divisional areas, based on data indicative of an enlargement ratio of an object displayed on the display.

14 . The storage medium of claim 13 , wherein the computer program further controls the computer to execute functions of:

determining whether setup of the plurality of divisional areas is enabled, based on the resolution and the enlargement ratio; and

setting the plurality of divisional areas when the setup is enabled.

15 . The storage medium of claim 13 , wherein the computer program further controls the computer to execute functions of:

calculating a division number of the plurality of divisional areas, based on the resolution and the enlargement ratio; and

setting the plurality of divisional areas in accordance with the division number.

16 . The storage medium of claim 13 , wherein the computer program further controls the computer to execute a function of making, when the mouse pointer is moved in units of the divisional area, a speed for moving the mouse pointer to be higher than a speed for moving the mouse pointer in accordance with the operation information before setting the plurality of divisional areas.
