Abstract

An electronic apparatus is provided. The electronic apparatus includes a processing unit configured to extract at least one frame selected from a plurality of frames of moving-picture data as a candidate thumbnail image, wherein the at least one frame corresponds to at least one frame selected according to a plurality of thumbnail extraction criteria, and to determine at least one candidate thumbnail image selected from a group comprising candidate thumbnail images obtained by the extracting, as at least one final thumbnail image, based on a thumbnail extraction criterion to which the candidate thumbnail images obtained by the extracting respectively correspond, and a display unit configured to display the at least one final thumbnail image.

Claims

1. An electronic apparatus comprising:

a processing unit configured to;

extract at least one frame selected from a plurality of frames of moving-picture data as a candidate thumbnail image, wherein the at least one frame corresponds to at least one frame selected according to a plurality of thumbnail extraction criteria; and

determine at least one candidate thumbnail image selected from a group comprising candidate thumbnail images obtained by the extracting, as at least one final thumbnail image, according to a thumbnail extraction criterion to which the candidate thumbnail images obtained by the extracting respectively correspond; and

a display unit configured to display the at least one final thumbnail image.

2. The electronic apparatus of claim 1, wherein the plurality of thumbnail extraction criteria comprises at least one selected from a group comprising a case when a scene shift, in which a scene is changed from a previous frame to a current frame in correspondence with a value equal to or greater than a reference value, is detected, a case when a face is detected, and a case when a registered face is recognized, or a combination thereof.

3. The electronic apparatus of claim 2, wherein the processing unit is further configured to determine the at least one final thumbnail image, by providing a first priority to the case when the registered face is recognized and providing a second priority to the case when the face is detected.

4. The electronic apparatus of claim 3, wherein the processing unit is further configured to determine the at least one final thumbnail image, by providing a third priority to a thumbnail extraction criterion to which a greatest number of the candidate thumbnail images obtained by the extracting correspond.

5. The electronic apparatus of claim 2, further comprising a storage unit configured to store at least one piece of contact information, and a face image relating to the at least one piece of contact information,

wherein the registered face comprises a face image related to the at least one piece of contact information.

6. The electronic apparatus of claim 2, wherein the case when the scene shift is detected is at least one selected from a group comprising a case when a change between frames corresponds to a value equal to or greater than the reference value, a case when a new object is detected, and a case when a photographing condition is changed in correspondence with the value equal to or greater than the reference value, or a combination thereof.

7. The electronic apparatus of claim 1, wherein the processing unit is further configured to determine a number of the at least one final thumbnail image, based on a time length of the moving-image data and a number of the candidate thumbnail images obtained by the extracting.

8. The electronic apparatus of claim 1, wherein the processing unit is further configured to determine that the at least one final thumbnail image includes an image corresponding to a first frame of the moving-picture data.

9. The electronic apparatus of claim 1,

wherein the electronic apparatus further comprises a user input unit configured to receive a user selection of selecting one of the displayed at least one final thumbnail image, and

wherein the processing unit is further configured to reproduce the moving-picture data, the reproducing of the moving-picture data starting from a frame corresponding to the selected at least one final thumbnail image, if the one of the displayed at least one final thumbnail image is selected.

10. The electronic apparatus of claim 1,

wherein the electronic apparatus further comprises a storage unit configured to store the moving-picture data, and

wherein the processing unit is further configured to generate and store a moving-picture file that comprises the moving-picture data and the at least one final thumbnail image in the storage unit.

11. The electronic apparatus of claim 1, further comprising a storage unit configured to store a hit-rate table indicating a total sum of hit rates for each of a scene shift detection, a face detection and a face recognition in relation to the moving-picture data.

12. An image processing method comprising:

extracting, by a processing unit, at least one frame selected from a plurality of frames of moving-picture data as a candidate thumbnail image, wherein the at least one frame corresponds to at least one frame selected according to a plurality of thumbnail extraction criteria;

determining, by the processing unit, that at least one final thumbnail image, selected from the candidate thumbnail images obtained by the extracting, is obtained by the extracting, based on a thumbnail extraction criterion to which the candidate thumbnail images obtained by the extracting respectively correspond; and

displaying the at least one final thumbnail image.

13. The image processing method of claim 12, wherein the plurality of thumbnail extraction criteria comprises at least one selected from a group comprising a case when a scene shift, in which a scene is changed from a previous frame to a current frame in correspondence with a value equal to or greater than a reference value, is detected, a case when a face is detected, and a case when a registered face is recognized, or a combination thereof.

14. The image processing method of claim 13, wherein, in the determining of the at least one final thumbnail image, the processing unit determines the at least one final thumbnail image, by providing a first priority to the case when the registered face is recognized and providing a second priority to the case when the face is detected.

15. The image processing method of claim 14, wherein, in the determining of the at least one final thumbnail image, the processing unit determines the at least one final thumbnail image, by providing a third priority to a thumbnail extraction criterion to which a greatest number of the candidate thumbnail images obtained by the extracting correspond.

16. The image processing method of claim 13, wherein the registered face comprises a face image that is related to and stored in contact information that is stored in an electronic apparatus for performing the image processing method.

17. The image processing method of claim 13, wherein the case when the scene shift is detected is at least one selected from a group comprising a case when a change between frames corresponds to a value equal to or greater than the reference value, a case when a new object is detected, and a case when a photographing condition is changed in correspondence with the value equal to or greater than the reference value, or a combination thereof.

18. The image processing method of claim 12, further comprising determining a number of the at least one final thumbnail image, based on a time length of the moving-image data and a number of the candidate thumbnail images obtained by the extracting.

19. The image processing method of claim 12, wherein the determining of the at least one final thumbnail image comprises determining that the at least one final thumbnail image includes an image corresponding to a first frame of the moving-picture data.

20. The image processing method of claim 12, further comprising reproducing the moving-picture data, the reproducing of the moving-picture data starting from a frame corresponding to the selected at least one final thumbnail image, if the one of the displayed at least one final thumbnail image is selected.

21. A non-transitory computer-readable storage medium storing instructions that, when executed, cause at least one processor to perform the method of claim 12.
