Claim:
A method for generating at least one thumbnail image from a plurality of consecutive frames in a video stream by an apparatus for generating thumbnail images, the method comprising: selecting, by the apparatus for generating thumbnail images, a first frame and a second frame in a video stream, wherein the first frame is included at beginning of the first portion and the second frame is included at end of the first portion; reducing, by the apparatus for generating thumbnail images, at least one of resolution and size of the first frame and the second frame to respectively generate a first reduced frame and a second reduced frame; comparing, by the apparatus for generating thumbnail images, said first reduced frame with said second reduced frame to determine whether difference between the first reduced frame and the second reduced frame exceeds a first threshold; and selecting, by the apparatus for generating thumbnail images, a reduced frame from the first reduced frame and the second reduced frame, in response to determining that the difference between the first reduced frame and the second reduced frame does not exceed the first threshold, generating a thumbnail from the selected reduced frame.
