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:
determining whether an image having a first aspect ratio includes at least one person based at least in part on focus information in metadata; and
displaying a thumbnail generated from the image based on a second aspect ratio, wherein the second aspect ratio is based on whether the image includes at least one person.
2. The method of claim 1 , wherein determining whether the image includes at least one person comprises determining whether the at least one person is detected within a threshold distance of an area indicated by the focus information if the metadata for the image comprises the focus information.
3. The method of claim 1 , wherein determining whether the image includes at least one person comprises determining whether face of the at least one person is recognized by using a face recognition function when capturing the image.
4. The method of claim 1 , wherein determining whether the image includes at least one person further comprises determining whether at least one piece of face information exists in a face recognition information if the metadata for the image comprises the face recognition information.
5. The method of claim 1 , wherein the second aspect ratio is a portrait-type aspect ratio which a lengthwise length is longer than a widthwise length.
6. The method of claim 1 , wherein the thumbnail displayed includes every person.
7. The method of claim 1 , wherein displaying the thumbnail generated from the image comprises:
detecting an image display event;
determining a representative area of the image as an area including a face of the person according to the size of an image display window; and
determining a size of the image for the determined representative area to be displayed.
8. The method of claim 1 , wherein the thumbnail is generated by cropping the image.
9. The method of claim 1 , wherein the second aspect ratio is different from the first aspect ratio.
10. The method of claim 1 , wherein the second aspect ratio is determined based on a size of an image display window.
11. The method of claim 1 , wherein displaying a thumbnail generated from the image based on the second aspect ratio further comprises:
when the image includes at least one person, the second aspect ratio has a longer length than width.
12. The method of claim 1 , wherein displaying a thumbnail generated from the image based on the second aspect ratio further comprises:
when the image does not include at least one person, the second aspect ratio has a longer width than length.
13. An electronic device comprising a display screen and a processor configured to:
determine whether an image having a first aspect ratio includes at least one person based at least in part on focus information metadata; and
display a thumbnail generated from the image based on a second aspect ratio, wherein the second aspect ratio is based on whether the image includes at least one person.
14. The electronic device of claim 13 , wherein the processor is configured to determine whether the at least one person is detected within a threshold distance of an area indicated by the focus information if the metadata for the image comprises the focus information.
15. The electronic device of claim 13 , wherein the processor is configured to determine whether face of the at least one person is recognized by using a face recognition function when capturing the image.
16. The electronic device of claim 13 , wherein the processor is further configured to determine whether at least one piece of face information exists in a face recognition information if the metadata for the image comprises the face recognition information.
17. The electronic device of claim 13 , wherein the second aspect ratio is a portrait-type aspect ratio which a lengthwise length is longer than a widthwise length.
18. The electronic device of claim 13 , wherein the thumbnail displayed includes every person.
19. The electronic device of claim 13 , wherein the processor is further configured to:
detect an image display event;
determine a representative area of the image as an area including a face of the person according to the size of an image display window; and
determine a size of the image for the determined representative area to be displayed.
20. The electronic device of claim 13 , wherein the thumbnail is generated by cropping the image.
21. The electronic device of claim 13 , wherein the second aspect ratio is different from the first aspect ratio.
22. The electronic device of claim 13 , wherein the second aspect ratio is determined based on a size of an image display window.
