A characteristic data such as the illuminance of each frame is measured. Neighboring frames are compared to detect the change in the characteristic data between frames. When the difference exceeds a threshold level a scene boundary is determined. The editor may then automatically move to a scene boundary in the forward or rewind direction so that the user can edit the scenes at exactly the boundary frame.Field of SearchHAND-HELD CAMERA WITH RECORDER IN A SINGLE UNIT | |
