Verfahren und Vorrichtung zum Detektieren eines Videoschnitts
摘要
A buffer memory (11) buffers a sequence of image data I0, I1, ... of respective frames while shifting them step by step and discarding the least recent one of them for each step. An inter-image distance calculating means (12) calculates the distance d(t-i, t-j) between respective pieces of image data held in the buffer memory (11) and stores such distance values in a distance table part (13) in a sequential order. A scene changing ratio calculating part (14) calculates the scene changing ratio C(t-jc) at time t while referring to the distance table part (13). A decision part (15) compares the scene changing ratio C(t-jc) with a predetermined threshold value to determine if the image of a preceding frame jc-th from the time t is a cut point. <IMAGE>
