Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-vehicle video reproducing apparatus for reproducing a movie or the like in a vehicle.

[0002]

2. Description of the Related Art There is known an on-vehicle video reproducing apparatus for reproducing a movie or the like stored in a large-capacity storage device such as a DVD in a vehicle cabin (for example, Japanese Patent Application Laid-Open No.
257973).

[0003] In this kind of in-vehicle video reproducing apparatus, the reproduction of a running image is prohibited so as not to hinder safe driving. Is automatically turned off, only the foreign language sound is broadcast, and there is a problem that the story of the subtitle movie cannot be understood every time the vehicle is driven.

[0004] It is an object of the present invention to prevent a story such as a subtitle movie being broadcast from being lost every time the vehicle runs.

[0005]

The present invention will be described with reference to FIG. 1 showing the configuration of an embodiment. (1) The invention of claim 1 provides foreign language audio data and Japanese subtitle data. A video storage means 1 for storing video data including video data, an image reproduction means 4 for reproducing an image including Japanese subtitles from the video data, an audio reproduction means 10 for reproducing foreign language audio from the video data, and a Japanese subtitle. Subtitle sound generating means 8 and 9 for generating Japanese sound from the data, vehicle state detecting means 2 and 3 for detecting whether the vehicle is stopped or running,
While the vehicle is stopped, image reproduction by the image reproducing means 4 and reproduction of foreign language sound by the sound reproducing means 10 are performed. Control means 6 for generating Japanese speech
And (2) The on-vehicle video reproducing apparatus according to claim 2 is configured such that the foreign language sound and the subtitle Japanese sound are mixed by the control means 6 and 11 during traveling.

In the section of the means for solving the above-described problem, a diagram of one embodiment is used for easy understanding of the description, but the present invention is not limited to this embodiment. .

[0007]

(1) According to the first aspect of the invention, while the vehicle is stopped, the reproduction of the image including the Japanese subtitles and the reproduction of the foreign language sound are performed, and while the vehicle is traveling, the reproduction of the image is prohibited. Since the Japanese audio is generated from the word caption data, it is possible to prevent a story such as a caption movie being broadcast from being lost each time the vehicle runs. (2) According to the invention of claim 2, since the foreign language sound and the Japanese sound of the subtitles are mixed during running, the broadcast of the foreign language sound is continued even if the stop and the running are repeated, and the running is performed. Since the Japanese sound of the subtitle is superimposed and broadcast only in the middle, in addition to the above-mentioned effect of claim 1, the occupant does not feel discomfort.

[0008]

FIG. 1 is a diagram showing the configuration of an embodiment. The storage device 1 is a large-capacity storage device such as a DVD, and can store movies and the like. In movies,
Some broadcast foreign language audio and images with Japanese subtitles. Note that the image may be a still image or a moving image. The vehicle speed sensor 2 is a sensor that detects a vehicle speed.
The traveling / stop determination unit 3 determines whether the vehicle is traveling or stopped based on the detected vehicle speed. The image reproducing unit 4 reproduces an image including Japanese subtitles from the video data stored in the storage device 1,
The data is developed in the memory 5 as image data. The image switching unit 6 outputs an image obtained from the memory 5 to the display 7 while the vehicle is stopped, and outputs a message image such as “Image cannot be displayed during traveling” to the display 7 during traveling. The text data capture unit 8 captures Japanese subtitle text data from the image data expanded in the memory 5,
The text data utterance unit 9 converts the text data into Japanese voice (hereinafter referred to as caption voice). Audio playback unit 10
Reproduces a foreign language sound stored in the storage device 1 together with the video. The sound mixing unit 11 outputs only the foreign language sound to the speaker 12 when the vehicle is stopped, and mixes the foreign language sound with the Japanese subtitle sound and outputs the mixed sound to the speaker 12 while the vehicle is running.

FIG. 2 is a flowchart showing a video reproducing operation according to one embodiment. In step 1, video data is read from the storage device 1 by the image reproducing unit 4 and expanded in the memory 5 as image data, and a foreign language sound is reproduced by the sound reproducing unit 10. In step 2, text data of Japanese subtitles is fetched from the image data developed in the memory 5 by the text data fetching unit 8. In the following step 3, the text data utterance unit 9 converts the text data into Japanese voice, that is, subtitle voice. In step 4, the traveling / stop determination unit 3 determines whether or not the vehicle is traveling based on the detected vehicle speed. If it is determined that the vehicle is traveling, the process proceeds to step 5, and if it is determined that the vehicle is stopped, the process proceeds to step 6. If the vehicle is running, the foreign language sound and the Japanese subtitle sound are mixed in step 5 and broadcast from the speaker 12, and the process proceeds to step 7. On the other hand, when the vehicle is stopped, only the foreign language voice is broadcast from the speaker 12 in step 6, and the process proceeds to step 7. In step 7, when the video to be reproduced ends, the process ends, otherwise, the process returns to step 4 to continue the above process.

As described above, while the vehicle is stopped, the reproduction of the image including the Japanese subtitles and the reproduction of the foreign language sound are performed. During the traveling, the reproduction of the image is prohibited, and the Japanese audio is generated from the Japanese subtitle data. To mix with foreign language audio,
It is possible to prevent a story of a movie with subtitles being broadcast from being lost every time the vehicle runs. Also, even if the vehicle stops and travels repeatedly, the foreign language audio is continuously broadcast and the Japanese audio of the subtitles is superimposed and broadcast only during traveling, so that the occupant does not feel uncomfortable.

In the above-described embodiment, an example has been described in which a foreign language sound is mixed with Japanese subtitle audio during broadcasting, but only the Japanese subtitle audio is broadcast during traveling. It may be. Specifically, in FIG. 1, while traveling, the voice mixing unit 11 does not mix the foreign language voice and the Japanese subtitle voice, and the text data utterance unit 9 converts the Japanese voice converted from the subtitle text data into the speaker 12. Broadcast from.

Further, in the above-described embodiment, an example is shown in which an image with foreign language audio and Japanese subtitles is broadcast, but the language of audio and subtitles is not limited to the above-described embodiment.
