Scene change detection in encoding digital pictures is disclosed. A statistical quantity μM is calculated for a given section in a current picture. A window of one or more sections is defined around a co-located section in a previous picture. A statistical sum E is calculated over the sections in the window. A difference between the statistical sum E and the statistical quantity μM is calculated. The difference between E and μM is used to determine whether the given section is a scene-change section. Whether the current picture is a scene-change picture may be determined from the number of scene change sections. Information indicating whether or not the current picture is a scene-change picture may be stored or transferred.
