Method and apparatus for providing slow motion video at normal motion play speed

摘要

A stream of video frames that is provided to a display device at a normal speed is processed to provide slow motion of a selected segment of the stream. Processing involves creating a dilated stream of the video frames. Each original frame of the segment is copied. The copied frames are located in the dilated stream adjacent to their respective original frames. The dilated stream is then provided to the display device at the normal playing speed. Slow motion of a segment or frames is provided by playing plural copies of each frame before playing the next frame. All the frames in the segment can be copied the same number of times. Alternatively, the frames in the segment can be copied an uneven number of times, wherein the frames near the beginning and end of the segment are copied fewer times than the frames in the middle of the segment.
