Abstract

An editing system having a controller for setting reproducing speed on the basis of reproducing speed data inputted via a user interface to a desired event allows e.g., slow-playback to be set to the desired event and so further realistic image can be easily generated. Thus, an editing system capable of high-speed real-time edition and having further improved usability can be realized. Moreover, when an in point of first video data (V2) is specified, the editing system starts a reproducing operation from a position that is a fixed time before the position of the specified in point and displays thus reproduced second video data (V3) on a display (2b), so that if the specification of the in point is late, the in point can be easily corrected by monitoring the reproducing second video data. As a result, an editing system capable of high-speed real-time edition and having further improved usability can be realized.
