Abstract
A scene change detection method includes calculating a first summation result of a plurality of minimum block matching costs associated with a plurality of blocks within a first frame, calculating a second summation result of a plurality of minimum block matching costs associated with a plurality of blocks within a second frame, and determining whether a scene change occurs according to the first and second summation results.
