Abstract

A method of processing an image is provided. The method includes identifying edge components of a background image by a unit of a predetermined size, identifying input coordinate points of a touch input which is input on a touch screen, determining distorted coordinate points by applying the edge components to the input coordinate points, and displaying a drawing image formed by connecting the distorted coordinate points, on the background image.

First claim

What is claimed is:

1. A method of processing an image of an electronic device, the method comprising:
identifying, by a controller of the electronic device, edge components of a background image by a unit of a predetermined size;
identifying, by the controller, input coordinate points of a touch input which is input on a touch screen;
determining, by the controller, distorted coordinate points by applying the edge components to the input coordinate points; and
displaying, by the controller, a drawing image which is formed by connecting the distorted coordinate points on the background image,
wherein the determining of the distorted coordinate points by applying the edge components to the input coordinate points comprises moving the input coordinate points to horizontal and vertical coordinates corresponding to the edge components, by calculating the horizontal and vertical coordinates for the input coordinate points,
wherein the identifying of the edge components comprises detecting a value of the vertical edge component and a value of the horizontal edge component by a predetermined unit, and
wherein the moving of the input coordinate points to the horizontal and vertical coordinates corresponding to the edge components comprises:
moving the input coordinate points vertically in proportion with the magnitude of the value of the vertical edge component, and
moving the input coordinate points horizontally in proportion with the magnitude of the value of the horizontal edge component.

2. The method as claimed in claim 1 , wherein the unit of the predetermined size is a unit of a pixel.

3. The method as claimed in claim 1 , wherein the identifying of the edge components comprises filtering vertical and horizontal edge components for the background image.

4. The method as claimed in claim 3 , further comprising:
determining an intensity of the edge components; and
outputting at least one of a voice and a vibration according to a magnitude of the intensity of the edge components.

5. The method as claimed in claim 3 , wherein the moving of the input coordinate points to the horizontal and vertical coordinates corresponding to the edge components comprises moving the input coordinate points so as to correspond to a filtered value of the vertical and horizontal edge components.

6. The method as claimed in claim 1 , wherein the identifying of the edge components comprises filtering a diagonal edge component for the background image.

7. The method as claimed in claim 1 , further comprising:
determining an intensity of the edge components; and
outputting at least one of a voice and a vibration according to a magnitude of the intensity of the edge components.

8. An electronic device comprising:
a display unit;
a touch input interface unit;
at least one controller; and
a memory unit configured to store at least an image processing program,
wherein the image processing program is executed by the controller, and comprises instructions which when executed by the controller, further configure the controller to:
identify edge components of a background image by a unit of a predetermined size,
identify input coordinate points of a touch input which is input on the touch input interface unit,
determine distorted coordinate points by applying the edge components to the input coordinate points, and
provide a drawing image formed by connecting the distorted coordinate points on the background image,

wherein the instructions when executed by the controller, further configure the controller to move the input coordinate points to horizontal and vertical coordinates corresponding to the edge components, by calculating the horizontal and vertical coordinates for the input coordinate points, and
wherein the instructions when executed by the controller, further configure the controller to:
detect a value of the vertical edge component and a value of the horizontal edge component by a predetermined unit,
move the input coordinate points vertically in proportion with the magnitude of the value of the vertical edge component, and
move the input coordinate points horizontally in proportion with the magnitude of the value of the horizontal edge component.

9. A non-transitory computer-readable storage medium for storing at least one program, wherein the at least one program comprises instructions which when executed by a controller, configure the controller to:
identify edge components of a background image by a unit of a predetermined size,
identify input coordinate points of a touch input which is input on the touch input interface unit,
determine distorted coordinate points by applying the edge components to the input coordinate points, and
provide a drawing image formed by connecting the distorted coordinate points on the background image,
wherein the instructions when executed by the controller, further configure the controller to move the input coordinate points to horizontal and vertical coordinates corresponding to the edge components, by calculating the horizontal and vertical coordinates for the input coordinate points, and
wherein the instructions when executed by the controller, further configure the controller to:
detect a value of the vertical edge component and a value of the horizontal edge component by a predetermined unit,
move the input coordinate points vertically in proportion with the magnitude of the value of the vertical edge component, and
move the input coordinate points horizontally in proportion with the magnitude of the value of the horizontal edge component.
