[0002]

2. Description of the Related Art Conventionally, a parallax barrier system has been proposed as one of display systems for observing a stereoscopic image or a three-dimensional image without using glasses.

In the parallax barrier type three-dimensional image display device without glasses, the parallax barrier stripes are electronically generated, and the shape of the generated barrier stripes (the number of stripes,
3D image without glasses, which is versatile and versatile, can be used as a 2D image display by electronically variably controlling the width, interval), position (phase), density, etc. according to the purpose of use. The invention that realizes a display device is disclosed in Japanese Patent Laid-Open No. HEI-3
-119889 gazette (H04N13 / 04).

Further, in the technique relating to the three-dimensional image display without glasses disclosed in this publication, the left and right images are alternately arranged in vertical stripes by an image display device such as a video projector corresponding to the parallax direction of the left and right eyes. The projected multi-directional image is projected on the rear screen, and the electronic barrier is arranged at a position separated from the rear screen by a certain distance. The electronic barrier is generated by the barrier generating means when displaying a three-dimensional image, and the electronic barrier is stopped by the barrier generating means when displaying a two-dimensional image.

In short, the disclosed technique is a parallax arranged in vertical stripes corresponding to the parallax direction of both eyes so that the horizontally long display screen has compatibility between two-dimensional image display and three-dimensional image display. • Arrange the barrier stripes in the horizontal direction at a predetermined distance from the display surface. The barrier generating means generates a parallax barrier to form a barrier stripe when the image display device projects a three-dimensional image, and a parallax barrier when the image display device projects a two-dimensional image. -The barrier generation is stopped, and the barrier generation surface is made colorless and transparent without forming barrier stripes.

Therefore, in the three-dimensional image display device as described above, the horizontally long display screen is compatible with the two-dimensional image display and the three-dimensional image display when observed by the observer from one direction. Is. Therefore, this compatibility is applied only when the display screen is observed from one direction, even when the device is a portable type that is carried around.

In view of the above, when the apparatus is portable, the display screen is changed to a horizontally long size of 4: 3 or 16: 9 corresponding to television broadcasting, and a fixed size display is transformed to a vertically long size. It has been desired to develop an atypical display, that is, a bidirectional three-dimensional image display device that can be observed from other directions on a vertically long display screen.

On the other hand, conventionally, GPS (Global Posit)
The GPS receiver that receives the radio waves sent from the satellite decodes the position information of the latitude and longitude values of the receiving point, and uses the decoded position information and the trajectory information such as the traveling direction of the vehicle and the geomagnetic sensor. The current position is detected from the atmospheric pressure information, etc., and the current position is identified and displayed on the video map of the monitor device from the detected current position information and the map information obtained by reproducing the external recording medium such as the CD-ROM or IC memory card. At the same time, a car navigation system (hereinafter, abbreviated as car navigation system) for searching a route from the current position to a destination and guiding the traveling of the car has been favored.

In a conventional car navigation system using a CD-ROM as an external recording medium, the monitor device is installed near the dashboard of the passenger seat of the car. The monitor screen has a screen corresponding to 4: 3 or 16: 9 so that it can be used in common not only as a map display for car navigation but also as a television broadcast or video playback monitor. The display screen is in the horizontal direction according to the landscape size.

Further, the car navigation is display-controlled so that the current position is located at the center of the display screen with the upper part of the display screen facing north, similar to a normal printed map, and guides the road from the current position to the destination. Is done.

Further, the car navigation system has a function of assisting road guidance, for example, displaying a map rotated on the display screen, setting the current position at the left end of the display screen, and setting the destination at the right end of the display screen. Set to be located at, and display a guide from the current position to the destination from end to end of the display screen, and reduce the map to check the positional relationship between the current position and the destination and its surroundings. Additional functions such as enlargement of the map for displaying and confirming in detail are also provided.

These additional functions are appropriately operated by an observer, and are used as auxiliary functions for selecting a map in a desired form on the display screen and guiding and displaying an optimum driving route from the current position to the destination on the map. It

As a function of displaying the position information as described above, a portable type liquid crystal television generally used is equipped with a GPS receiver or the like so that the current position can be confirmed as necessary. The device has been commercialized as a liquid crystal TV navigation "Gorilla" NV-P1 (released on November 12, 1995, released by Denpa Shimbun October 12, 1995).

This device is a portable type and has a GPS antenna and a receiving device, a TV tuner, a reproducing device for a CD or a CD-G disc, and a secondary battery as a power source, which is built in the main body device to watch television broadcasting, The GPS function is used mainly for outdoor use such as hiking in mountainous areas and guidance in urban areas.

Further, since the device itself is large and its weight is relatively heavy, it is used as a shoulder bag. When used for navigation, the observer holds the device with both hands and always observes the display screen from one direction of the device with the display screen in the landscape orientation.

As described above, since the device is also used for receiving a normal television broadcast, when searching for a hiking route such as a mountain area on the display screen using the navigation function described above, the displayed map is observed. 4: 3 or 1 whose display screen corresponds to television broadcasting as seen from the viewer
Due to the horizontally long size of 6: 9, there was a drawback that the destination was not displayed on the display screen depending on the topography of the mountainous area.

That is, since the standard of the device is to always display in the horizontal direction of the display screen, even if the current position is set at the lower end of the display screen and the destination is set at the upper part of the display screen. , A map such as a mountain area displayed on the display screen is widely displayed in the horizontal direction, and the destination is located outside the upper part of the display screen. Also, when the map is reduced in this state, the details of the destination are not displayed.

Therefore, when the observer wants to search a detailed hiking route such as a mountain area on the display screen by the device, the current position is set at the left end of the display screen and the destination is set at the right end of the display screen. At the same time, the device had to be held in the vertical direction of the display screen for observation. Also, if the current position and the destination are set from one end to the other in the laterally long direction of the display screen, the actual traveling direction and the displayed direction are different, which causes confusion in using the device.

From the above, when the portable device is provided with a navigation function and is used outdoors or the like, the device is configured to be held by one hand and the device is not only observed from one direction of the display screen, It was necessary to provide a position information display device that can be observed from two directions.

Further, when the device is used as a portable navigation, it is necessary to observe mountains and valleys in a state in conformity with the actual topography.

Therefore, as a portable navigation device, it is an object to provide a three-dimensional image display device capable of displaying an image in the horizontal and vertical directions of a display screen and observing map information in a three-dimensional image. Was becoming.
