A method for determining camera-induced scene changes in a sequence of visual information-bearing frames which constitute a single shot first determines camera-induced motion between each of a plurality of pairs frames within a single camera shot. The camera-induced motion for each of the pairs of frames is decomposed into at least a first component. The values of the first component for each of the pairs of frames are summed to form a first cumulative signal. A scene change is indicated when the first cumulative signal meets a certain decision criteria.
