Abstract

A terminal may be provided that includes: a touch screen; a processor; and a controller. When a touch is input to the touch screen, the processor detects a position of the touch and a magnitude of a pressure of the touch and transfers information on the touch position and information on the magnitude of the touch pressure to the controller. Based on the magnitude of the touch pressure, the controller changes an image which is displayed on a change target region around the touch position, and displays the changed image on the touch screen. The change target region includes a first region and a second region disposed within the first region, an image enlarged perpendicularly to the boundary of the first region is displayed on the first region, and an image reduced perpendicularly to the boundary of the second region is displayed on the second region.

Claims

1. A terminal comprising:

a touch screen;

a processor; and

a controller;

wherein, when a touch is input to the touch screen, the processor detects a position of the touch and a magnitude of a pressure of the touch and transfers information on the touch position and information on the magnitude of the touch pressure to the controller;

wherein, based on the magnitude of the touch pressure, the controller changes an image which is displayed on a change target region around the touch position, and displays the changed image on the touch screen; and

wherein the change target region comprises a first region and a second region disposed within the first region, an image enlarged perpendicularly to the boundary of the first region is displayed on the first region, and an image reduced perpendicularly to the boundary of the second region is displayed on the second region.

2. The terminal of claim 1,

wherein the processor transfers a signal including information on a capacitance change amount according to the input touch to the controller;

wherein the controller calculates a touch region based on the capacitance change amount; and

wherein, when a size of the touch region is increased, a size of the change target region is increased, and when the size of the touch region is reduced, the size of the change target region is reduced.

3. The terminal of claim 2, wherein a shape of the change target region and a shape of the touch region have a similar relationship with each other.

4. The terminal of claim 1, wherein, when the magnitude of the touch pressure is reduced, a size of the second region is increased, and when the magnitude of the touch pressure is increased, the size of the second region is reduced.

5. The terminal of claim 4, wherein, when the magnitude of the touch pressure exceeds a first predetermined touch pressure value, the size of the second region is reduced for a first time interval, and the size of the second region is increased for a second time interval.

6. The terminal of claim 5,

wherein the processor transfers a signal including information on a capacitance change amount according to the input touch to the controller;

wherein the controller calculates a touch region based on the capacitance change amount; and

wherein the touch region is included in the second region.

7. The terminal of claim 4, wherein, when the magnitude of the touch pressure exceeds a second predetermined touch pressure value, the change target region comprises a third region which displays a crack image or a circuit board image.

8. The terminal of claim 7, wherein, when the magnitude of the touch pressure is increased, a size of the third region is increased.

9. The terminal of claim 7, wherein, when the magnitude of the touch pressure is increased, a magnification of the image which is displayed on the third region is increased.

10. The terminal of claim 7, wherein, when the magnitude of the touch pressure is increased, a brightness or saturation of the image which is displayed on the third region is increased.

11. The terminal of claim 1, wherein, when the magnitude of the touch pressure is reduced, a degree of enlargement of the image which is displayed on the first region and a degree of reduction of the image which is displayed on the second region are reduced, and when the magnitude of the touch pressure is increased, the degree of enlargement of the image which is displayed on the first region and the degree of reduction of the image which is displayed on the second region are increased.

12. The terminal of claim 11, wherein, when the magnitude of the touch pressure exceeds a first predetermined touch pressure value, the degree of enlargement of the image which is displayed on the first region and the degree of reduction of the image which is displayed on the second region are reduced for a first predetermined time interval, and the degree of enlargement of the image which is displayed on the first region and the degree of reduction of the image which is displayed on the second region are increased for a second predetermined time interval.

13. The terminal of claim 11, wherein, when the magnitude of the touch pressure exceeds a second predetermined touch pressure value, the change target region comprises a third region which displays a crack image or a circuit board image.

14. The terminal of claim 13, wherein, when the magnitude of the touch pressure is increased, a size of the third region is increased.

15. The terminal of claim 13, wherein, when the magnitude of the touch pressure is increased, a magnification of the image which is displayed on the third region is increased.
