Title
(EN) METHOD FOR BROWSING A COLLECTION OF VIDEO FRAMES AND CORRESPONDING DEVICE
Abstract
(EN)

The invention relates to a method for browsing a collection of P video frames through a user interface comprising N cells disposed along a time line with N<P. The method comprises the steps of: —determining (S1) a subset of N key frames by uniformly subsampling the collection of P video frames, —displaying (S2) the N key frames in the N cells according to a chronological order, the N cells being classified as current cell, past cells and future cells, —receiving (S3) an input command requesting to transfer a selected key frame displayed in a cell Ci to a cell Cj of the UI, —in response to the input command, updating (S4) the key frame displayed in the cell Cj by the selected key frame and updating accordingly the key frames displayed in the other cells by updating key frames while maintaining the chronological order of the key frames in the N cells and adjusting the subsampling interval by pieces.
