APPARATUS AND METHOD FOR CREATION THUMBNAIL VIEW

An apparatus and a method for creating thumbnail are provided to generate animation thumbnail in consideration for the luminance of frames of video sequences. A thumbnail creating event is sensed(200). An I frame, which is a reference frame, is extracted from a GOP(Group Of Pictures) of a frame(202)...

description An apparatus and a method for creating thumbnail are provided to generate animation thumbnail in consideration for the luminance of frames of video sequences. A thumbnail creating event is sensed(200). An I frame, which is a reference frame, is extracted from a GOP(Group Of Pictures) of a frame(202). A GOIF(Group Of I Frame) is created(204). Luminance difference between the reference frame and former reference frames contained in the GOIF is measured(206). The reference frame having lamination difference contained in a specific range is set as a prediction candidate frame(208). The standard deviation of each prediction candidate frame is measured, and the frame whose standard deviation is the largest is selected as the core frame(210). The selected core frames are connected in order to create one animation thumbnail(212).
