Abstract

Virtual object based image processing method and apparatus are provided. At least one virtual object is selected and applied to the underlying image such as a preview image obtained by a camera in order to create a merged image. The selected virtual object has a modification attribute allowing parts of the underlying image to be modified. A user can easily obtain various merged images decorated with the modification attributes of the selected virtual object by checking in advance merged images overlapped with the virtual object before saving them.

Claims

1. A method, operable in a control unit, for image processing based on a virtual object, the method comprising:

selecting at least one virtual object, each of the at least one including a virtual image and a modification attribute, the virtual image having a particular form and being placed on a specific underlying image, and the modification attribute allowing at least one part of the underlying image to be modified;

creating a merged image by locating the selected virtual object on a specific position of the underlying image and by modifying the parts of the underlying image according to the modification attribute; and

outputting the merged image.

2. The method of claim 1, further comprising:

changing the position of the selected virtual object in response to a suitable input signal.

3. The method of claim 2, further comprising:

creating a new merged image by modifying the at least one part of the underlying image in consideration of the changed position of the selected virtual object.

4. The method of claim 1, further comprising:

changing at least one of;

a size and the modification attribute of the selected virtual object.

5. The method of claim 4, further comprising at least one of:

changing the size of the virtual image of the selected virtual object located on the underlying image according to a change in size of the selected virtual object; and

modifying the underlying image according to a change in the modification attribute of the selected virtual object.

6. The method of claim 1, further comprising:

changing a number of the selected virtual object.

7. The method of claim 6, further comprising:

changing at least one of;

a position, a size and the modification attribute of each selected virtual object; and

modifying the underlying image by applying the changed modification attribute of each selected virtual object.

8. The method of claim 1, wherein the underlying image includes a preview image displayable on a camera unit.

9. The method of claim 8, further comprising at least one of:

receiving an input signal of a shutter key for capturing a merged preview image in which the selected virtual object is applied to the preview image; and

storing the merged preview image.

10. The method of claim 1, wherein the virtual object includes at least one of:

a candlelight virtual object having a virtual image and a modification attribute, the virtual image being formed of a candle and the light, and the modification attribute varying brightness of the underlying image;

a bubble virtual object having a virtual image enclosed by a looped curve, and a refraction attribute giving different values in the refractive index to the inside and outside of the virtual image;

a flashlight virtual object having a virtual image formed of a flashlight, and a modification attribute giving a brilliant flood of light to a limited area of the underlying image; and

a wave virtual object giving a disturbance effect to the underlying image.

11. The method of claim 1, wherein the selecting of the virtual object includes selecting at least two virtual object, each having corresponding modification attributes.

12. The method of claim 11, wherein the outputting of the merged image includes:

creating the merged image by simultaneously applying the corresponding modification attributes to the underlying image.

13. An apparatus for image processing based on a virtual object, the apparatus comprising:

a memory unit configured to store at least one virtual object each including a virtual image and a modification attribute, the virtual image having a particular form and being placed on a specific underlying image, and the modification attribute allowing at least one part of the underlying image to be modified;

a control unit configured to;

create a merged image by locating the at least one selected virtual object on a specific position of the underlying image

modify at least one part of the underlying image according to the modification attribute, and

output the merged image;

an input unit configured to create at least one of an input signal for selecting at least one of the at least one virtual object and an input signal for selecting the underlying image; and

a display unit configured to display the merged image.

14. The apparatus of claim 13, wherein the input unit is further configured to create at least one of:

an input signal for changing the position of the at least one selected virtual object in response to a suitable input signal;

an input signal for changing at least one of the size and the modification attribute of the selected virtual object;

an input signal for changing a number of the at least one selected virtual object; and

an input signal for further selecting other virtual objects.

15. The apparatus of claim 14, wherein the control unit is further configured to create a new merged image by applying at least one of:

an image of the selected virtual object changed in position,

an image of the selected virtual object changed in size,

an image of the selected virtual object changed in number, and an image of the further selected virtual object, to the underlying image.

16. The apparatus of claim 14, wherein the control unit is further configured to create the merged image by simultaneously applying corresponding modification attributes of at least two virtual objects to the underlying image.

17. The apparatus of claim 16, wherein the at least two virtual objects have modification attributes selected from the group consisting of:

similar, identical and different.

18. The apparatus of claim 13, wherein the virtual object includes at least one of:

a candlelight virtual object having a virtual image and a modification attribute, the virtual image being formed of a candle and the light, and the modification attribute varying brightness of the underlying image;

a bubble virtual object having a virtual image enclosed by a looped curve, and a refraction attribute giving different values in the refractive index to the inside and outside of the virtual image;

a flashlight virtual object having a virtual image formed of a flashlight, and a modification attribute giving a brilliant flood of light to a limited area of the underlying image; and

a wave virtual object giving a disturbance effect to the underlying image.

19. The apparatus of claim 18, further comprising:

a camera unit configured to obtain a preview image as the underlying image in response to a suitable input signal.

20. The apparatus of claim 19, wherein the display unit is further configured to display a merged preview image in which the selected virtual object is applied to the preview image when the camera unit is activated, and wherein the memory unit is further configured to store the merged preview image in response to a suitable input signal.
