At least one visual significance metric is determined ( 12 ) for at least some frames belonging to an original series of frames ( 11 ). Key frames are identified ( 13 ) as a function, at least in part, of the visual significance metric. Cumulative visual significance values are then determined ( 14 ) for at least some of the frames that intervene between each pair of key frames. These cumulative visual significance values are then used to identify ( 15 ) frames of additional content interest. Various frames are then selected ( 16 ) for use in a visual summary. In one embodiment, all of the key frames and frames of additional content interest are selected for inclusion in the visual summary.
