Patent ID: 8307399

Claim:
A method of displaying videos on a mobile communication terminal, the method comprising: displaying, via a display unit of the mobile communication terminal, a list of videos that can be reproduced in a first display area of the display unit; receiving a selection of a specific video from the list of videos, said specific video including all image frames of the specific video; simultaneously displaying a first subset of a plurality of the image frames representing the specific video in a second display area of the display unit, the first subset of the plurality of the image frames comprising the image frames among beginning and end portions of the specific video; simultaneously displaying a second subset of a plurality of the image frames representing the specific video in the second display area of the display unit when the size of the display unit is increased without a user's setting input, the second subset of the plurality of the image frames comprising the images frames among the beginning and end portions of the specific video, wherein the second subset of the plurality of the image frames includes more image frames than the first subset of the plurality of the image frames; displaying a moveable indicator within an area defined by the displayed first or second subsets of the plurality of the image frames, the moveable indicator indicating a currently selected specific image frame among the beginning and end portions of the specific video; and when a particular image frame among the simultaneously displayed first or second subset of the plurality of the image frames is selected, reproducing the specific video beginning at the selected particular image frame, wherein the first and second display areas are predefined with on the display unit, wherein the list of videos on the first display area and the first subset or the second subset of the plurality of the image frames on the second display area are simultaneously displayed, and wherein the method further comprises: determining a number of image frames for the first and second subset of the plurality of the image frames based on a variation amount of motion of a current frame with respect to a previous image frame; selecting the current frame to be included in the first or second subset of the plurality of the image frames when the variation amount of motion exceeds a predetermined threshold; and adjusting a size of each image frame based on how well each image frame matches the predetermined selection criterion threshold, wherein displaying the first and second subsets of the plurality of the image frames displays the adjusted size of the plurality of the image frames in the second display area.
