Abstract

A method of providing a summary of a video in an electronic device includes determining first summary frames from among a plurality of frames of the video, based on a preset criterion; generating a plurality of pieces of first summary information corresponding to the first summary frames; and displaying at least one of the first summary frames and the plurality of pieces of first summary information, together with at least one frame of the video.

First claim

What is claimed is:

1 . A method of providing a summary of a video in an electronic device, the method comprising:
determining first summary frames from among a plurality of frames of the video, based on a preset criterion; generating a plurality of pieces of first summary information corresponding to the first summary frames; and displaying at least one of the first summary frames and the plurality of pieces of first summary information, together with at least one frame of the video.

2 . The method of claim 1 , further comprising:
obtaining key frames located at preset time intervals of the video; and determining the first summary frames based on a variation in a respective key frame.

3 . The method of claim 1 , wherein the first summary frames are displayed together with the at least one frame of the video, and
wherein the method further comprises: receiving a user input to select a first summary frame from among the first summary frames; and reproducing the video corresponding to a location of the selected first summary frame.

4 . The method of claim 1 , further comprising:
receiving a user input to select a first location and a second location of the video; extracting a portion of the first summary frames included between the first location and the second location from the first summary frames; extracting at least one first summary information corresponding to the extracted portion of the first summary frames; obtaining a plurality of pieces of second summary information from a plurality of videos stored in the electronic device; searching for at least one second summary information that matches with the at least one first summary information, from the plurality of pieces of second summary information; and displaying at least one summary frame, of the plurality of videos, corresponding to the searched at least one second summary information.

5 . The method of claim 1 , wherein the first summary frames are displayed together with the at least one frame of the video, and
wherein the method further comprises: receiving a user input to select a partial area of at least one of the first summary frames; obtaining at least one first summary information corresponding to the selected partial area; obtaining a plurality of pieces of second summary information from a plurality of videos stored in the electronic device; searching for at least one second summary information that matches with the at least one first summary information, from the plurality of pieces of second summary information; and displaying at least one summary frame, of the plurality of videos, corresponding to the searched at least one second summary information.

6 . The method of claim 1 , further comprising:
extracting summary videos of the video by using the first summary frames; and generating a master summary based on the summary videos.

7 . The method of claim 1 , further comprising:
further displaying a plurality of second summary frames that are stored in the electronic device; receiving a user input to select a second summary frame; and reproducing the video corresponding to a location of the selected second summary frame.

8 . The method of claim 1 , further comprising in response to determining that a storage space of the electronic device is less than or equal to a preset threshold value, storing only the first summary frames and the plurality of pieces of first summary information, from among data included in the video, in the electronic device.

9 . An electronic device comprising:
a display; and a processor configured to: determine first summary frames from among a plurality of frames of the video, based on a preset criterion, generate a plurality of pieces of first summary information corresponding to the first summary frames, and control the display to display at least one of the first summary frames and the plurality of pieces, together with at least one frame of the video.

10 . The electronic device of claim 9 , wherein the processor is further configured to obtain key frames located at preset time intervals of the video, and determine the first summary frames based on a variation in a respective key frame.

11 . The electronic device of claim 9 , wherein the processor is further configured to control the display to display the first summary frames, together with the at least one frame of the video,
wherein the electronic device further comprises an input unit configured to receive a user input to select a first summary frame from among the displayed first summary frames, and wherein the processor is further configured to reproduce the video corresponding to a location of the selected first summary frame.

12 . The electronic device of claim 9 , further comprising an input unit configured to receive a user input to select a first location and a second location of the video,
wherein the processor is further configured to extract a portion of the first summary frames included between the first location and the second location from the first summary frames, extract at least one first summary information corresponding to the extracted portion of the first summary frames, obtain plurality of pieces of second summary information from a plurality of videos stored in the electronic device, search for at least one second summary information that matches with the at least one first summary information, from the plurality of pieces of second summary information, and display at least one summary frame of the plurality of videos corresponding to the searched at least one second summary information.

13 . The electronic device of claim 12 , wherein the processor is further configured to obtain locations of the first summary frames, obtain summary videos corresponding to the locations of the first summary frames, and generate a master summary based on the summary videos.

14 . The electronic device of claim 9 , further comprising a memory configured to store the first summary frames and the plurality of pieces of first summary information,
wherein the processor is further configured to determine whether a storage space of the memory is less than or equal to a preset threshold value, and wherein the memory is further configured to, when it is determined that the storage space is less than or equal to the preset threshold value, store only the first summary frames and the plurality of pieces of first summary information from among data included in the video.

15 . An electronic device comprising:
a memory; a processor; an input unit configured to receive a user input to select a first location and a second location of a video; and a display, wherein the processor is configured to obtain first summary information corresponding to at least one of first frames included between the first location and the second location, obtain at least one piece of second summary information corresponding to second frames of the video, the second frames excluding the first frames, and search for second summary information that matches with the first summary information from among the at least one piece of second summary information, and wherein the display is configured to display a partial video, of the video, corresponding to the searched second summary information.

16 . The electronic device of claim 15 , wherein the processor is further configured to determine a summary frame of the video based on the searched second summary information, and
wherein the display is further configured to display the summary frame.

17 . The electronic device
