Method for generating thumbnail image and electronic device thereof
A method of displaying a thumbnail image and an electronic device thereof are provided. The method of displaying the thumbnail image of the electronic device includes detecting meta data and object information for an image, determining an aspect ratio of the thumbnail image with respect to the image on the basis of the detected meta data and object information, and displaying the thumbnail image with respect to the image according to the determined aspect ratio.
1. A method comprising:
extracting metadata from an image having a first aspect ratio;
selecting, by an electronic device, a second aspect ratio based on the metadata;
generating, by the electronic device, a thumbnail having the second aspect ratio by cropping the image; and
displaying the thumbnail in an image display window of the electronic device;
wherein the metadata includes focus information and the second aspect ratio is selected, at least in part, based on the focus information.
2. The method of claim 1 , further comprising extracting object information from the image, wherein the second aspect ratio is also selected based on the object information, when the object information does not conflict with the metadata.
3. The method of claim 2 , wherein the object information indicates that an object of the image comprises at least one of a person and a scenery.
4. The method of claim 1 , further comprising detecting whether the image depicts a person based on the metadata, wherein the second aspect ratio is a portrait-type aspect ratio when the image depicts the person.
5. The method of claim 4 , further comprising detecting whether the image depicts a scenery based on the metadata, wherein the second aspect ratio is a landscape-type aspect ratio when the image depicts the scenery.
6. The method of claim 2 , further comprising:
detecting a conflict between the metadata and the object information; and
detecting respective priorities that are assigned to the metadata and the object information;
wherein the second aspect ratio is selected based on the metadata only when the metadata is assigned a higher priority than the object information.
7. The method of claim 1 , wherein the second aspect ratio is different from the first aspect ratio.
8. The method of claim 1 , wherein the second aspect ratio is a portrait-type aspect ratio when at least one face of a person is depicted in the image.
9. The method of claim 8 , wherein the second aspect ratio is a landscape-type aspect ratio when the image does not depict the at least one face.
10. The method of claim 1 ,
wherein the second aspect ratio is selected based on a size of the image display window.
11. An electronic device comprising a display screen and a processor configured to:
extract metadata from an image having a first aspect ratio;
select a second aspect ratio based on the metadata;
generate a thumbnail having the second aspect ratio by cropping the image; and
display the thumbnail on the display screen;
wherein the metadata includes focus information and the second aspect ratio is selected, at least in part, based on the focus information.
12. The electronic device of claim 11 , wherein the processor is further configured to extract object information from the image, and the second aspect ratio is also selected based on the object information, when the object information does not conflict with the metadata.
13. The electronic device of claim 12 , wherein the object information indicates that an object of the image comprises at least one of a person and a scenery.
14. The electronic device of claim 11 , wherein the processor is further configured to detect whether the image depicts a person based on the metadata, wherein the second aspect ratio is a portrait-type aspect ratio when the image depicts the person.
15. The electronic device of claim 14 ,
wherein the processor is further configured to detect whether the image depicts a scenery based on the metadata, wherein the second aspect ratio is a landscape-type aspect ratio when the image depicts the scenery.
16. The electronic device of claim 12 , wherein the processor is further configured to:
detect that the metadata conflicts with the object information; and
detect respective priorities that are assigned to the metadata and the object information;
wherein the second aspect ratio is selected based on the metadata only when the metadata is assigned a higher priority than the object information.
17. The electronic device of claim 11 , wherein the second aspect ratio is different from the first aspect ratio.
18. The electronic device of claim 11 , wherein the second aspect ratio is a portrait-type aspect ratio when at least one face of a person is depicted in the image.
19. The electronic device of claim 18 , wherein the second aspect ratio is a landscape type aspect ratio when the image does not depict the at least one face.
20. The electronic device of claim 11 , wherein the second aspect ratio is selected based on a size of an image display window.
