ABSTRACT:
An apparatus for constructing frames for low-speed reproduction of a moving picture recorded in an interlaced scanning mode. A user interface receives a user setting speed for the low-speed reproduction. A field selector generates a field select mode signal for constructing second moving picture frames (for slow-speed playback) from first moving picture frames (for normal-speed playback) in response to the input user setting speed. A frame construction unit, in response to the field select mode signal, repeatedly selects moving picture data of a first field and a second field contained in each of the first moving picture frames, to construct the second moving picture frames corresponding to the first moving picture frames, wherein the number of times each frame is selected is determined by the user setting speed. The apparatus can construct frames for low-speed reproduction from frames for normal-speed reproduction while reproducing a natural image without vibration or mixing-up the time order of the moving picture.
