FIG. 4 is an explanatory diagram for explaining video editing in this embodiment. The original video 400 is divided into a plurality of scenes 401 to 407. Scene 401-407 force Corresponds to the above scene. The scenes 401 to 407 may be divided every time or may be divided in units of data amount. Here, the scenes 401 to 404 included in the original video 400 are selected, while the scenes 405 to 407 are not selected. Then, the edited scene 410 is created by connecting the selected scenes 401 to 404.

[0027] The creation of the edited video 410 will be described. First, keywords for video editing are entered. Prioritize the keyword categories by default and classify scenes 401-407 in that order. Here, scenes 401 to 404 are selected, and each time they are selected, the total time is totaled. When this total time reaches a predetermined time, the selection ends. This priority order can also be set by viewer input.

[0028] Furthermore, the titles of the scenes 401 to 407 and a list of words indicating keywords or contents can be presented to the viewer, and the priority level of the power to be viewed can be obtained. Alternatively, priority order selection can be accepted. Then, scenes 401 to 404 are also selected for the obtained priority power, and an edited video 410 is created.

[0029] Scenes 401 to 404 can also be selected based on the travel route or the name of a nearby facility, address, genre, or landmark. The selected scenes 401 to 404 are edited in the order of arrival Z passage schedule. Or, edit based on the required interval time such as the driving route or the name of the nearby facility, address name, genre name, landmark name, etc. that generates the playback keyword.

Next, scene determination processing will be described. Necessary scenes are determined on the basis of metadata (scene indentus). The metadata is data attached to the original video 400 or data added to the original video 400 during recording.

[0031] The division of scenes 401 to 407 will be described. The scenes 401 to 407 can be classified by using the telop and the speech words included in the original video 400 as judgment materials. Alternatively, changes in the volume of the original video 400, sound interruptions, etc. can be classified as judgment materials. Alternatively, changes in the characters of the original video 400 can be classified as judgment materials. Alternatively, the original video 400 can be analyzed and classified as judgment material.

[0032] When the scenes 401 to 407 are segmented, a little front force at the segmented positions can be reproduced in order to prevent the head from being cut off. Of the scenes 401 to 407, the scene 401 to 404 is saved. Saving the scene corresponds to the case of saving the video data of the scene 401 to 404 itself and the scene 401 to 404 of the original video 400. Only the time code indicating the part may be saved. An index title representing the contents of each scene is attached to scenes 401-404. In addition, scenes 401 to 404 are given the time required for playback of each scene.

[0033] Scene editing will be described. For scene editing, scenes 401 to 404 are searched using a scene index or the like as a material based on keywords, and the searched scenes 401 to 404 are connected to create an edited video 410. The edited video 410 can be created by connecting the video data of scenes 401 to 404 themselves. It can also be created as a list of time codes that indicate where to join the original video 400.

[0034] When there is a restriction on the reproduction time, a scene in which the reproduction required time is within the restriction time is preferentially selected. If there is no such thing, use a scene that exceeds the time limit as the time limit. If playback time is limited, select the number of scenes within the limit. When the joining order is requested, the number of scenes to be selected rearranges the selected scenes within the range in the requested order.

FIG. 5 is a flowchart for explaining processing of the video reproduction method of this embodiment. First, the required travel time to the destination is extracted (step S501). This travel time is the estimated time it will take to reach the destination from the current position.

Next, a reproduction keyword is extracted (step S502). This replay keyword can be related to the location where the vehicle is traveling. It can also be related to the destination. Specifically, the name of a nearby facility, the name of a place, the name of a landmark, and the like can be given. Next, it is determined whether or not the original video 400 has a scene corresponding to the playback keyword (step S503). These scenes are the scenes 401 to 407 shown in FIG. 4, and the determination is executed by comparing the information included in the scenes 401 to 407 with the reproduction keyword. If there is no corresponding scene (step S503: No), the process returns to step S502.

[0038] If there is a corresponding scene (step S503: Yes), the scene is extracted (step S504). Specifically, when the corresponding scenes are scenes 401 to 404, the scenes 401 to 404 are extracted. At this time, the required playback time of the selected scene is integrated. Specifically, the total time of scenes 401 to 404 is obtained. Next, it is determined whether or not the total playback time required for the selected scene is within the required travel time (step S505). If it is not within the travel time (step S50 5: No), return to step S503.

[0039] If it is within the required travel time (step S505: Yes), the scene is connected to the selected scene (step S506). Specifically, the selected scenes 401 to 404 are connected to form one edited video 410. Then, the edited video 410 is played back (step S507). After playback, the series of processing ends.

[0040] According to the embodiment described above, it is possible to extract and reproduce a scene according to the running state of the vehicle from the recorded video. For example, if the recorded video is 3 hours when the running time is 1 hour, it will not be impossible to watch for the first hour. Further, it is not necessary to fast-forward unnecessary scenes by the viewer's own operation. Therefore, it is not necessary to view unnecessary scenes, and only the scenes that have been viewed can be viewed as needed.

[0041] In addition, by playing a video suitable for the stop location, it is possible to view the visited video in comparison with the scenery of the actual visit. By playing back images suitable for the location where you are traveling, you can watch the images while comparing them with the scenery while you are traveling, and if you are planning to stop, images related to the location where you plan to stop It can prevent you from forgetting to stop.

Note that the video playback method described in the present embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program is hard disk, flexible disk, CD -Recorded on a computer-readable recording medium such as ROM, MO, DVD, etc., and executed by being read by the computer. The program may be a transmission medium that can be distributed via a network such as the Internet.
