ABSTRACT:
A buffer memory buffers a sequence of image data I.sub.0, I.sub.1, . . . 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 calculates the distance d(t-i, t-j) between respective pieces of image data held in the buffer memory and stores such distance values in a distance table part in a sequential order. A scene changing ratio calculating part calculates the scene changing ratio C(t-j.sub.c) at time t while referring to the distance table part. A decision part compares the scene changing ratio C(t-j.sub.c) with a predetermined threshold value to determine if the image of a preceding frame j.sub.c -th from the time t is a cut point.
