<p><P>PROBLEM TO BE SOLVED: To improve the operability of fast-forwarding and rewinding in video playback processing based on multi-touch operation. <P>SOLUTION: A position detection unit 115 detects two touch point positions on a display screen, and a ratio acquisition unit 116 acquires a ratio of a rotation angle and a time on the basis of a distance between the detected touch point positions. A rotation angle acquisition unit 117 acquires a rotation angle obtained by the change in a relative position of two touch point positions. A playback time determination unit 113 specifies a time to be deviated from a reference time on the basis of the rotation angle and the ratio to determine the playback time after fast-forwarding or rewinding of video data corresponding to the reference time, and a playback processing unit 114 plays back video data corresponding to the determined playback time. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
