Classification: CPC G  H | IPC G

Claim 0:
1. A method of providing a video summary by an electronic device, the method comprising:
receiving, by the electronic device, a video including a plurality of frames;
determining, by the electronic device, at least one view point of a user viewing the video;
determining, by the electronic device, at least one region of interest (ROI) of the user in at least one frame among the plurality of frames based on the at least one view point of the user;
identifying, by the electronic device, a frame set from the plurality of frames including the at least one ROI based on determining the at least one ROI in the at least one frame;
providing, by the electronic device, the video summary based on the identified frame set; and
displaying the video summary on a display of the electronic device,
wherein the identifying the frame set from the plurality of frames including the at least one ROI comprises:
determining, by the electronic device, an absolute completeness score of the video; and
determining, by the electronic device, absolute frame excitation information of the video based on the absolute completeness score,

wherein the absolute frame excitation information comprises information for driving relative frame excitation associated with the frame set for sequencing the frame set, and
wherein the determining the absolute frame excitation information of the video based on the absolute completeness score comprises:
obtaining, by the electronic device, a speed of the ROI, an intensity of the ROI, an appearance frequency of the ROI, and a duration of playback, in each frame of the plurality of frames; and
determining, by the electronic device, the absolute frame excitation information of the video based on the obtained speed of the ROI, the obtained intensity of the ROI, the obtained appearance frequency of the ROI, and the obtained duration of playback.
