Abstract

A method for displaying one or more images in an electronic device is provided, which includes displaying a first image; retrieving at least one second image on the basis of additional information of the first image; comparing at least one first feature point of the first image with at least one second feature point of the at least one second image; displaying information on whether at least one recommended image with respect to the first image exists, based on a result of the comparison; and if the at least one recommended image exists, displaying the at least one recommended image according to a user input.

Claims

1. A method for displaying one or more images in an electronic device, the method comprising:

displaying a first image;

retrieving at least one second image on the basis of additional information of the first image;

comparing at least one first feature point of the first image with at least one second feature point of the at least one second image to determine whether they match each other;

displaying information on whether at least one recommended image with respect to the first image exists, based on a result of the comparison; and

if the at least one recommended image exists, displaying the at least one recommended image according to a user input.

2. The method of claim 1, wherein the first image is pre-stored, or received from outside to be stored.

3. The method of claim 1, wherein the additional information is information included in a tag of the first image.

4. The method of claim 1, wherein comparing at least one first feature point of the first image with at least one second feature point of the at least one second image comprises comparing directions, sizes, and a created time of the first image and the at least one second image.

5. The method of claim 4, wherein displaying the at least one recommended image according to the user input comprises displaying the first image together with the at least one second image, of which the directions, the sizes, and the created time are compared.

6. The method of claim 1, wherein the user input is a tactile input by which a screen of the electronic device is touched, or a non-tactile input by which a screen of the electronic device is not touched.

7. A method for displaying one or more images in an electronic device, the method comprising:

determining at least one first feature point of a first image;

retrieving at least one second image on the basis of location information of the first image;

detecting at least one second feature point of the at least one second image;

determining at least one recommended image according to a result of comparing the at least one first feature point with the at least one second feature point; and

displaying the at least one recommended image.

8. The method of claim 7, wherein determining the at least one first feature point of the first image comprises:

counting a matching count value of each of the at least one first feature point; and

determining the at least one first feature point having the matching count value greater than or equal to a predetermined reference value as at least one important point.

9. The method of claim 7, wherein displaying the at least one recommended image comprises:

whenever the first image is displayed, displaying an icon corresponding to each of the at least one recommended image in the first image; and

when a user input for selecting the icon is received, displaying the corresponding at least one recommended image instead of the first image.

10. The method of claim 7, wherein retrieving the at least one second image on the basis of the location information of the first image comprises retrieving photos that have been taken at a location of a same GPS coordinate as that of the first image, or at a location near thereto.

11. The method of claim 8, wherein counting the matching count value of each of the at least one first feature point comprises, in comparing the first image with each of the retrieved at least one second image, increasing the matching count value of each of the at least one first feature point that matches the at least one second feature point by one.

12. The method of claim 8, further comprising:

determining a first feature area including the at least one important point in the first image;

determining a second feature area including the at least one second feature point that matches the at least one important point of the at least one recommended image;

comparing the first feature area with the second feature area; and

determining whether an image of the second feature area is enlarged, reduced, or reversed, compared with an image of the first feature area.

13. The method of claim 12, further comprising:

if the image of the second feature area is reduced compared with the image of the first feature area, displaying the first image together with a reduction indicator in the first feature area thereof; and

when a user input for selecting the reduction indicator is received, displaying the at least one recommended image instead of the first image.

14. The method of claim 12, further comprising:

if the image of the second feature area is enlarged compared with the image of the first feature area, displaying the first image together with an enlargement indicator in the first feature area thereof; and

when a user input for selecting the enlargement indicator is received, displaying the at least one recommended image instead of the first image.

15. The method of claim 12, further comprising:

if the image of the second feature area is reversed compared with the image of the first feature area, displaying the first image together with an reversal indicator in the first feature area thereof; and

when a user input for selecting the reversal indicator is received, displaying the at least one recommended image instead of the first image.

16. An electronic device for displaying one or more images, the electronic device comprising:

a display configured to display a first image;

an image control module configured to;

determine at least one first feature point in the first image,

retrieve at least one second image on the basis of additional information of the first image,

extract at least one second feature point from the at least one second image,

determine at least one recommended image on the basis of a result of comparing the at least one first feature point with the at least one second feature point, and

control the display to display the at least one recommended image according to a user input.

17. The electronic device of claim 16, wherein the image control module is further configured to count a matching count value of each of the at least one first feature point, and to determine the at least one first feature point having a matching count value greater than or equal to a predetermined reference value as at least one important point.

18. The electronic device of claim 16, wherein the display is further configured to display the first image together with an icon corresponding to each of the at least one recommended image, and to display the corresponding at least one recommended image instead of the first image according to a user input for selecting the icon.

19. The electronic device of claim 16, wherein the image control module is further configured to retrieve photos that have been taken at a location of a same GPS coordinate as that of the first image, or a location near thereto.

20. The electronic device of claim 17, wherein,

in comparing the first image with each of the retrieved at least one second image, the image control module is further configured to increase the matching count value of each of the at least one first feature point that matches the at least one second feature point by one.
