Abstract

An electronic device is provided. The electronic device includes an input device configured to receive a touch gesture that includes a drawing action, a display configured to output a drawing to an area corresponding to the touch gesture, and a processor configured to identify a number of drawing actions that are input into each unit portion in the area based on the drawing action, and a number of touches input into each unit portion in the area, and determine display attributes of the drawing in each unit portion based on the number of drawing actions and the number of touches, wherein the drawing action includes a touch from a time when a touch input occurs to a time when the touch input ends.

First claim

What is claimed is:

1 . An electronic device comprising:
an input device configured to receive a touch gesture that includes a drawing action; a display configured to output a drawing to an area corresponding to the touch gesture; and a processor configured to:
identify a number of drawing actions that are input into each unit portion in the area and a number of touches input into each unit portion in the area based on the drawing action, and
determine display attributes of the drawing in each unit portion based on the number of drawing actions and the number of touches,
wherein the drawing action includes a touch from a time when a touch input occurs to a time when the touch input ends.

2 . The electronic device of claim 1 , wherein the processor is further configured to, if the drawing action is received, determine the display attributes of the drawing such that the chromaticity of the drawing in the unit portion increases based on the number of touches.

3 . The electronic device of claim 2 , wherein the processor is further configured to, if the number of touches reaches a predetermined number of touches, determine the display attributes of the drawing such that the chromaticity of the drawing decreases based on the increase in the number of touches.

4 . The electronic device of claim 1 , wherein the processor is further configured to, when two drawing actions are received, determine the display attributes of the drawing such that the chromaticity of the drawing increases based on the increase in the number of touches.

5 . The electronic device of claim 4 , wherein the processor is further configured to, if the number of touches reaches a predetermined number of touches, determine the display attributes of the drawing such that the chromaticity of the drawing remains constant.

6 . The electronic device of claim 1 , wherein the processor is further configured to:
create an edge of the drawing corresponding to a second touch gesture based on a brush stroke image, and display the created edge of the drawing.

7 . The electronic device of claim 6 , wherein the processor is further configured to dispose a brush stroke image at a predetermined interval along a path of the second touch gesture.

8 . The electronic device of claim 6 , further comprising a memory configured to store the brush stroke image.

9 . The electronic device of claim 6 , wherein the processor is further configured to:
randomly select the brush stroke image from a group of brush stroke images, and create the edge of the drawing based on the selected brush stroke image.

10 . A method for simulating a digital watercolor image in an electronic device, the method comprising:
receiving a touch gesture that includes a drawing action through an input device; and outputting a drawing in the area corresponding to the touch gesture, wherein the outputting of the drawing comprises:
identifying a number of drawing actions that are input into each unit portion in the area based on the drawing action,
identifying a number of touches that are input into each unit portion, and
determining display attributes of the drawing in each unit portion based on the basis of the number of drawing actions and the number of touches, and
wherein the drawing action includes moving a touch from a time when a touch input occurs to a time when the touch input ends.

11 . The method of claim 10 , wherein the determining of the display attributes comprises, if the drawing action is received, determining the display attributes of the drawing such that the chromaticity of the drawing in the unit portion increases based on the number of touches.

12 . The method of claim 11 , wherein the determining of the display attributes comprises, if the number of touches reaches a predetermined number of touches, determining the display attributes of the drawing such that the chromaticity of the drawing decreases based on the increase in the number of touches.

13 . The method of claim 10 , wherein the determining of the display attributes comprises, when two drawing actions are received, determining the display attributes of the drawing such that the chromaticity of the drawing increases based on the increase in the number of touches.

14 . The method of claim 13 , wherein the determining of the display attributes comprises, if the number of touches reaches a predetermined number of touches, determining the display attributes of the drawing such that the chromaticity of the drawing remains constant.

15 . The method of claim 10 , wherein the providing of the drawing comprises:
creating an edge of the drawing corresponding to a second touch gesture based on a brush stroke image; and displaying the created edge of the drawing.

16 . The method of claim 15 , wherein the creating of the edge comprises disposing a brush stroke images at a predetermined interval along a path of the second touch gesture.

17 . The method of claim 15 , wherein the creating of the edge comprises storing the brush stroke image.

18 . The method of claim 15 , wherein the creating of the edge comprises;
randomly selecting the brush stroke image from a group of brush stroke images; and creating the edge of the drawing based on the selected brush stroke image.

19 . A non-transitory computer readable medium that, when executed by a processor, cause the processor to:
receive a touch gesture that includes a drawing action through an input device; identify a number of drawing actions that are input into each unit portion in the area based on the drawing action; identify a number of touches that are input into each unit portion; determine display attributes of the drawing in each unit portion based on the number of drawing actions and the number of touches; and output the drawing based on the display attributes, wherein the drawing action includes moving a touch from a time when a touch input occurs to a time when the touch input ends.
