  The position of the IC card 201 is detected based on information from the acceleration sensor 202 provided in the IC card 201. The direction and distance of the movement of the IC card 201 are calculated based on the acceleration when the IC card 201 is moved by the user and the moving time, and the current position is obtained. The IC card 201 is placed in the position initialization area 112 at the time of system startup or editing start, and the position initialization area 112 is set as a reference position of the IC card 201. Thereafter, the information of the IC card 201 is obtained from information obtained by the acceleration sensor 202. Find the position.

  Further, by using a plurality of wireless LAN access point units 110, a method of detecting a position based on a difference in time when radio waves radiated from the IC card 201 reach each wireless LAN access point or a difference in radio wave level is used. Also good.

  Next, playlist creation will be described. FIG. 3 shows an example of a method for determining the reproduction order of video data by the IC card 201 of the present embodiment. By the user's operation, the video clip A is registered in the IC card 201a, the video clip B in the IC card 201b, the video clip C in the IC card 201c, and the video clip D in the IC card 201d. The user moves each IC card from the position initialization area 112 to the editing area 111, and arranges the IC cards from left to right in the order of playback. When these four IC cards are arranged on the editing area as A, B, D, and C from the left as shown in the figure, the position detection unit 106 determines whether each IC card is based on the acceleration from each IC card and the time of movement. Calculate how much you have moved from the initialization area. After the positions of all the IC cards are detected, the IC card position information is sorted in the horizontal direction and the vertical direction. The order sorted in the horizontal direction is the reproduction order, and here, it can be detected that the IC cards 201a, 201b, 201d, and 201c are arranged in order. As shown in the figure, the playlist generation unit 107 creates a playlist to be played back in the order of A, B, D, and C. The user can arbitrarily rearrange the positions of the IC cards even during playback, and the playlist generation unit 107 corrects the playlist based on the IC card position information detected by the position detection unit 106. The system control unit 105 reads the video data from the media IF unit 103 or the video holding unit 104 according to the created playlist, and transfers the video data to the signal processing unit 108. After the signal processing unit 108 performs signal processing, the video output unit 109 outputs video data to the outside.

  FIG. 4 is a diagram illustrating an example of a method for dissolving between video data according to the present embodiment. As shown in FIG. 4, when the IC card in which the video clip C is registered by the user is placed obliquely below the IC card in which the video clip B is registered, the position detection unit 106 displays the position information of each IC card in the vertical direction. It is determined that the IC card in which the video clip C is registered is below the IC card in which the video clip B is registered. The playlist generation unit 107 inserts a dissolve between the video clip B and the video clip C based on the vertical position information, and the signal processing unit performs the dissolve. If the horizontal positions of the two IC cards are the same, the two video data registered in the IC card are superimposed and reproduced simultaneously.

  FIG. 5 is a diagram illustrating an example of deleting a clip from a playlist. As shown in FIG. 5, when the IC card is turned over, the position detection unit 106 determines that the IC card is turned upside down based on the rotation direction data sent from the IC card when turned over. When the position detection unit 106 sorts the positions of the IC cards, the card that is turned over is ignored. Therefore, the clip registered in the IC card turned upside down on the playlist is deleted. If the IC card is displayed again, it is added to the playlist.

  FIG. 6 is a diagram illustrating an example of adding a one-color screen to the playlist. As shown in FIG. 6, when the IC cards are separated from each other by a certain distance, the playlist generation unit inserts a single color video such as black or white between the video clips.

  FIG. 7 is a diagram illustrating an example of adding fade-in and fade-out effects to video. As shown in FIG. 7, when the IC card is tilted to the right or left by a certain angle, the signal processing unit 108 performs fade-in and fade-out processing on the video data, respectively.

  FIG. 8 is a diagram illustrating an example of a playback control method. As shown in FIG. 8, when the IC card corresponding to the clip being played is rotated, the position detection unit 106 detects the direction and speed of rotation. The system control unit 105 changes the reproduction speed according to the detected rotation direction and rotation speed. That is, fast forward, rewind, slow play, and pause of the video clip registered in the IC card are performed.

  FIG. 9 is a diagram illustrating an example of a method for switching video data to be output. Switching of the video to be output is performed by a button provided on the IC card. As shown in FIG. 9, even when a playlist is being reproduced, the clip registered on the IC card with the selected button pressed is given priority regardless of the reproduction order. To be played.

  FIG. 10 is a diagram illustrating an example of a camera input switching method using the video switching function. Video information is created from the video input from each camera and registered in each IC card. The user can switch the image of the camera to be output externally by selecting a button provided on the IC card. The video from each camera can be confirmed on the video display section of the IC card.

  With the present invention configured as described above, the user can intuitively edit video by creating a playlist simply by rearranging a plurality of IC cards in which video information is registered in the order in which they want to play back. Playback control and output switching can be performed.

  With the video editing apparatus of the present invention, a user can create a desired playlist simply by rearranging a plurality of IC cards in which video information is registered in the order of playback, and intuitively edit and playback video. Since it can be switched, it can also be applied to the purpose of editing the order of reproduction in improvisation.
