Abstract

A method of processing an image involves detecting a face from a first image; determining a composition of the first image; selecting a composition of a second image according to the composition of the first image; and generating the second image including the face by trimming the first image, according to the composition of the second image.

First claim

What is claimed is:

1. A method of processing an image, the method comprising:
detecting a face from a first image;
determining a category of the first image, wherein the category comprises a face-focused image, a face-landscape combined image, and a landscape image;
selecting a composition of a second image according to the category of the first image; and
generating the second image comprising the face by trimming the first image, according to the composition of the second image.

2. The method of claim 1 , further comprising:
storing the first image; and
storing the second image.

3. The method of claim 1 , wherein the determining of the category comprises determining a composition of the first image based on a position of the face, a size of the face, the number of faces, or an aspect ratio of the first image.

4. The method of claim 3 , further comprising determining whether a trimming operation can be performed, according to detection information regarding the face or the composition of the first image, and
wherein the selecting of the composition and the generating of the second image are performed only when the trimming operation can be performed according to a result of the determining.

5. The method of claim 4 , wherein the determining of the trimming operation comprises determining that the trimming operation cannot be performed if a plurality of faces are detected from the first image, if a face is not detected from the first image, or if a size of the face is greater than a reference value.

6. The method of claim 1 , further comprising, if a plurality of faces are detected from the first image, selecting faces to be included in the second image based on a size of each of the plurality of faces or a distance between the plurality of faces, and
wherein the selecting of the composition comprises selecting the composition of the second image based on the size of each of the plurality of faces or the distance between the plurality of faces.

7. The method of claim 6 , wherein, if the plurality of faces is detected from the first image, the generating of the second image comprises generating the second image by separately trimming each of the plurality of faces, or generating the second image by performing a trimming operation to comprise two or more faces from among the plurality of faces.

8. The method of claim 1 , further comprising performing a post-processing operation for adjusting the clearness of a face and the clearness of a background in the second image according to the category of the first image.

9. The method of claim 1 , further comprising editing the composition of the second image according to a user input.

10. The method of claim 1 , further comprising storing relation information indicating that the first image and the second image comprise the same face.

11. An image processing apparatus comprising:
a face detecting unit configured to detect a face from a first image;
a category determining unit configured to determine a category of the first image, wherein the category comprises a face-focused image, a face-landscape combined image and a landscape image;
a composition selecting unit configured to select a composition of a second image according to the category of the first image; and
an image generating unit configured to generate the second image comprising the face by trimming the first image, according to the composition of the second image.

12. The image processing apparatus of claim 11 , further comprising a data storage unit configured to store the first image and the second image.

13. The image processing apparatus of claim 12 , wherein the data storage unit is configured to store relation information indicating that the first image and the second image comprise the same face.

14. The image processing apparatus of claim 11 , wherein the category determining unit is configured to determine a composition of the first image based on a position of the face, a size of the face, the number of faces, or an aspect ratio of the first image.

15. The image processing apparatus of claim 14 , further comprising a trimming condition determining unit configured to determine whether a trimming operation can be performed, according to detection information regarding the face or the composition of the first image, and
wherein the image generating unit is configured to generate the second image if the trimming condition determining unit determines that the trimming operation can be performed.

16. The image processing apparatus of claim 15 , wherein the trimming condition determining unit is configured to determine that the trimming operation cannot be performed if a plurality of faces are detected from the first image, if a face is not detected from the first image, or if a size of the face is greater than a reference value.

17. The image processing apparatus of claim 11 , wherein, if a plurality of faces are detected from the first image, the composition selecting unit is configured to select faces to be included in the second image and the composition of the second image, based on a size of each of the plurality of faces or a distance between the plurality of faces.

18. The image processing apparatus of claim 17 , wherein, if the plurality of faces are detected from the first image, the image generating unit is configured to generate the second image by separately trimming each of the plurality of faces, or to generate the second image by performing a trimming operation to comprise two or more faces from among the plurality of faces.

19. The image processing apparatus of claim 11 , further comprising a post-processing unit configured to adjust the clearness of a face and the clearness of a background in the second image according to the category of the first image.

20. The image processing apparatus of claim 11 , further comprising a composition editing unit configured to edit the composition of the second image according to a user input.

21. A non-transitory computer-readable storage medium for storing computer program codes for executing a method of processing an image, the method comprising:
detecting a face from a first image;
determining a category of the first image, wherein the category comprises a face-focused image, a face-landscape combined image and a landscape image;
selecting a composition of a second image according to the category of the first image; and
generating the second image comprising the face by trimming the first image, according to the composition of the second image.

22. The computer-readable storage medium of claim 21 , wherein the method further comprises:
storing the first image; and
storing the second image.

23. The computer-readable storage medium of claim 21 , wherein the determining of the category of the first image comprises determining a composition of the first image based on a position of the face, a size of the face, the number of faces, or an aspect ratio of the first image.

24. The computer-readable storage medium of claim 23 , wherein the method further comprises determining whether a trimming operation can be performed, according to detection information regarding the face or the composition of the first image, and,
wherein the selecting of the composition of the second image and the generating of the second image are performed only when the trimming operation can be performed according to a result of the determining.
