BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multilingual display device used for displaying character information such as translations in movie theaters, theaters, TV conferences, etc., or for displaying presentation images in academic conferences and the like.

[0002]

2. Description of the Related Art Displaying translated subtitles in conventional movies is
Subtitles were displayed at the bottom of the screen or on the left and right edges in a form that was combined with the video information, but as a result of internationalization of movie release or ethnic independence within a single nation, subtitles for movies were displayed. Is also beginning to be required to support multiple languages. In the future, there is a growing demand for a system capable of displaying in multiple languages even when showing a single movie.

Further, in presentations such as international conferences, it is desirable that the language of the character portion of the display screen is ideally prepared in correspondence with the native language of the observer. In such a case, at present, there is no choice but to provide a number of displays dedicated to each language, but from the viewpoint of space factor, a display device capable of displaying a plurality of languages is required.

[0004]

In the normal subtitle display method in which a subtitle overlaps a part of the screen, multilingual display is limited to about three or four languages for one video source. In this case, the video information may be deleted due to the overlap between the video and the subtitle portion. Therefore, in order to support various languages, it is necessary to prepare different video sources and perform the screening in different movie theaters or the like depending on the language of the subtitles.

Further, in the case of presentations at academic conferences, it is desirable not only to display material images such as slides written in different languages, but also to display pointing information pointed to by the presenter as a pointer at the same time. It is desirable for natural communication construction that the line of sight of the presenter's pointer and the line of sight of the observer match. In order to realize this, a system that displays graphics, pointers, and texts on a single screen so that both the presenter and the observer can gaze, and that supports multilingual display is required.

It is an object of the present invention to provide a multi-lingual display device capable of observing images in different languages on the same display surface according to the viewing angle of the viewer on the display surface.

[0007]

According to a first aspect of the multilingual display device of the present invention, a first screen for image display is provided so that subtitles in different languages can be observed on the same display surface depending on the observer's observation position. And a second screen having directivity for displaying subtitles, a video synthesizing device that creates video information and a plurality of subtitle image information, and outputs these in synchronism with time, and is output from the video synthesizing device. A video projector that projects video information onto the first screen, and a plurality of subtitle projectors that project a plurality of subtitle image information output from the video synthesizing device onto the second screen at different angles. Is characterized by.

Further, in the multilingual display device according to the second aspect, in the case of presentations at academic conferences, presentations, etc., only the text portion displayed in the language on the display screen is made multilingual, and depending on the observation position, the audience can speak in their native language. In order to make it possible to observe, we created multiple synthetic image information consisting of directional synthetic image display screen and graphics information, pointing information, and text information written in multiple languages, and these were created. And a plurality of image projectors for projecting the respective combined image information output from the image combining device onto the combined image display screen at different angles. To do.

[0009]

The directional screen can change the directivity of outgoing light according to the incident angle of projection light. Therefore, by projecting multiple images written in different languages on a screen having directivity by changing the incident angle, it is possible to observe the images in each language depending on the viewing angle of the observer. Become.
