The display screen 104 is controlled by the screen arrangement unit 102 and the display unit 103.

The selection unit 101 selects either the map display mode or the general screen display mode. The map display mode can be a mode for instructing the use of car navigation functions such as route search and route guidance. In addition, the general screen display mode can be a mode for displaying television images using the display of the navigation device. Further, the selection unit 101 can select the map display mode while the mobile body is traveling. Further, the selection unit 101 can select the general screen display mode when a process involving video reproduction is instructed while the moving body is stopped.

When the map display mode is selected by the selection unit 101, the screen layout unit 102 directs the long side of the display screen 104 in the vertical direction. That is, the display screen is set vertically. On the other hand, when the general screen display mode is selected by the selection unit 101, the long side of the display screen 104 is displayed. The display screen 104 is arranged with the screen facing horizontally. That is, lay the display screen sideways. Further, in the initial state, the display screen 104 can be arranged with the long side of the display screen 104 oriented in the horizontal direction. Here, when the map display mode is selected, the display screen 104 is displayed by the screen arrangement unit 102. The display screen 104 can be arranged with its long side oriented vertically.

[0016] When the map display mode is selected by the selection unit 101, the display unit 103 extracts an area on the display screen 104 in which the long side of the display screen 104 is vertical and also displays the map information power on the display screen 104. indicate. The map information in this case is the entire map including the area where the moving body is traveling, and when the map is displayed on the display screen 104, a part of this intermediate force is extracted and displayed. Here, a vertically long area is extracted and displayed on the display screen 104.

FIG. 2 is a flowchart showing the processing of the navigation method that is useful for the embodiment of the present invention. First, the selection unit 101 selects either the map display mode or the general screen display mode (step S201). The selection unit 101 can select the map display mode while the mobile body is traveling, and can select the general screen display mode when a process involving video reproduction is instructed while the mobile body is stopped. Then, it is determined whether or not the map display mode has been selected (step S202).

[0018] When the map display mode is not selected by the selection unit 101 (step S202: No), that is, when the general screen display mode is selected, the screen layout unit 102 sets the long side of the display screen 104 horizontally. The display screen 104 is arranged in the direction (step S203), and a series of processing ends.

On the other hand, when the map display mode is selected by the selection unit 101 (step S202: Yes), the screen arrangement unit 102 arranges the display screen 104 with the long side of the display screen 104 directed in the vertical direction ( Step S204). In the initial state, the display screen 104 is arranged with the long side of the display screen 104 in the horizontal direction, and the screen arrangement unit 102 sets the long side of the display screen 104 in the vertical direction when the map display mode is selected. The display screen 104 is arranged toward the screen. Then, the display unit 103 extracts the map information power and displays the region on the display screen 104 with the long side of the display screen 104 being vertical, on the display screen 104 (step S205).

[0020] According to the embodiment described above, in the map display mode, the long side of the display screen is set in the vertical direction. In the general screen display mode, the long side of the display screen can be used horizontally. As a result, when viewing normal images such as AV, you can view normally on a horizontal display screen, but when you want to display a map screen when searching for a route, use a vertical display screen. You can see the map. By displaying the map screen vertically, it is possible to display the map screen as far as the direction of travel, so it is possible to provide a screen display that is easy for the user to check.

[0024] Here, the navigation program is executed by the CPU 301, and is displayed when the map display mode and the general screen display mode are selected between! / And between them, and the general screen display mode is selected. When the display screen is arranged with the long side of the screen oriented horizontally and the map display mode is selected, the area on the display screen where the long side of the display screen is vertical is extracted and the map information power is also extracted. It is a program to be displayed on.

The magnetic disk drive 304 controls reading and writing of data with respect to the magnetic disk 305 according to the control of the CPU 301. The magnetic disk 305 records data written under the control of the magnetic disk drive 304. As the magnetic disk 305, for example, HD (node disk) and FD (flexible disk) can be used.

The optical disk drive 306 controls reading and writing of data to the optical disk 307 according to the control of the CPU 301. The optical disc 307 is a detachable recording medium from which data is read according to the control of the optical disc drive 306. The optical disk 307 can also use a writable recording medium. Further, the removable recording medium may be a power MO of the optical disc 307, a memory card, or the like.

Another example of information recorded on the magnetic disk 305 and the optical disk 307 is map data used for route search and route guidance. The map data includes background data that represents features (features) such as buildings, rivers, and the ground surface, and road shape data that represents the shape of the road. Two-dimensional or three-dimensional data is displayed on the display screen of the display 314. Is drawn to. When the navigation device is guiding a route, the map data and the current vehicle location acquired by the CPU 301 are displayed in an overlapping manner.

The audio IZF 308 is connected to a microphone 309 for audio input and a speaker 310 for audio output. The voice received by the microphone 309 is AZD converted in the voice IZF308. In addition, sound is output from the speaker 310. Note that the sound input from the microphone 309 can be recorded on the magnetic disk 305 or the optical disk 307 as sound data.

[0029] Examples of the input device 311 include a remote controller, a keyboard, a mouse, and a touch panel that are provided with a plurality of keys for inputting characters, numerical values, various instructions, and the like. Furthermore, the input device 311 can be connected to other information processing terminals such as a digital camera or a mobile phone terminal to input / output data.

The video IZF 312 is connected to a video input camera 313 and a video output display 314. Specifically, the video IZF312 is output from, for example, a graphic controller that controls the entire display 314, a buffer memory such as VRAM (Video RAM) that temporarily records image information that can be displayed immediately, and a graphic controller. Based on the image data to be displayed, it is configured by a control IC or the like that controls display of the display 314.

[0031] The camera 313 captures images inside and outside the vehicle and outputs them as image data. Images captured by the camera 313 are recorded on the magnetic disk 305 or optical disk 307 as image data. It is possible to record. The display 314 displays icons, cursors, menus, windows, or various data such as characters and images. As this display 314, for example, a CRT, a TFT liquid crystal display, a plasma display, or the like can be adopted.

[0032] Communication IZF 315 is connected to a network via radio and functions as an interface between the navigation device and CPU 301.

[0034] The GPS unit 316 receives radio waves from GPS satellites and outputs information related to the position of the vehicle on which the navigation device is mounted. The output information of the GPS unit 316 is used when the CPU 301 calculates the current position of the vehicle together with output values of various sensors 317 described later. The information indicating the current location is information that identifies one point on the map data, such as latitude'longitude and altitude.

Various sensors 317 output information for determining the position and behavior of the vehicle, such as a vehicle speed sensor and an angular velocity sensor. The output values of the various sensors 317 are used by the CPU 301 to calculate the current location of the vehicle and to measure the amount of change in speed and direction.

[0036] Although illustration and description are omitted, the navigation apparatus includes the above-described configurations 301 to 300.

In addition to the 317, it has a configuration that realizes various functions such as playback of DVDs and CDs, reception of TV broadcasts, and recording!

FIG. 4 is an explanatory diagram for explaining switching between the vertical screen and the horizontal screen of the display screen.

A main body 400 of the navigation device is provided in a moving body, and a display 401 is connected to the main body 400. This display 401 is normally arranged in a horizontally long state, and here, when the navigation device is used for route search, the arrangement is changed to a horizontally long state force and a vertically long state. For that purpose, first, as shown in a direction 410, the display 401 is pushed forward toward the main body 400. The display 410 is then rotated as shown in direction 420. By rotating, the display 410 can be in a horizontally long state force.

Here, the case has been described in which the display 410 is set to the horizontally long state force, but the same applies to the case where the vertically long state force is also set to the horizontally long state. For example, if a navigation device is used for route search, but this time it is used for AV, the vertical state force is also changed to the horizontal state. Also in this case, the display 401 is pushed forward with respect to the main body 400 as shown in a direction 410. Then, the display 410 is rotated as shown in direction 420. By rotating it, the display 410 can be placed in a landscape orientation from a portrait orientation.

[0040] The information required for the map of the navigation should have a lot of content in the direction of travel. General navigation is horizontal (16: 9, 4: 3) considering AV usage. When using as a navigation system, the screen should be a vertical screen, and when switching to a TV, the screen should be easy to see for each application based on a landscape screen. When switching between the navigation function and the TV screen by operating the remote control, the vertical and horizontal positions change automatically to create an easy-to-read aspect according to the desired content.

FIG. 5 is an explanatory diagram for explaining the relationship between the orientation of the screen and the shape of the map to be extracted. In the conventional navigation device, since it is a horizontally long screen, a portion corresponding to the horizontally long screen is extracted and displayed as a display area. In this embodiment, a map is displayed using a vertically long screen. Therefore, the display area will have a different shape, so the area to be extracted must also match the portrait screen.

[0042] First, the entire area 500 represents the shape of the entire map. A part of the entire area 500 is displayed on the display screen, and when the position to be displayed moves, the position is moved while scrolling the screen. Since this entire area 500 is an entire displayable area, the position corresponding to the outside cannot be displayed. Here, when a map is displayed on a normal landscape screen, a portion of the display area 510 is extracted and displayed. On the other hand, when the map is displayed on a horizontally long screen, the display area 520 is extracted and displayed.

[0043] When the portion of the display area 510 is extracted, the current position and the previous portion of the travel route The minutes are displayed for the time being, but the further part of the travel route as extracted in the display area 520 is not displayed. When the display area 510 is displayed, it is displayed in a wide range in the horizontal direction, but the horizontal direction is not a traveling direction. Therefore, by extracting and displaying the display area 520 for display on a vertically long screen, it is possible to extract and display information in the vertical direction, which is the direction of travel, thereby making it more necessary than a map. The part can be presented to the user. This relationship will be further explained using FIG. 6 and FIG.

FIG. 6 is an explanatory diagram illustrating a map displayed in the case of a landscape screen. When a map is displayed on a landscape screen, a display area 510 is displayed on the screen, as shown in FIG. The display area 510 includes a current position 600 and a travel route 610, and the current position 600 and the travel route 610 can be confirmed through the displayed map. However, the area 620 is not included in the display area. Therefore, the part included in this area 620 cannot be confirmed on the display screen.

FIG. 7 is an explanatory diagram illustrating a map displayed in the case of a vertically long screen. When the map is displayed on a vertically long screen, the display area 520 is displayed on the screen, as shown in FIG. The display area 520 includes a current position 700 and a travel route 710, and the display area 510 includes a powerful area 720 that is not included. Therefore, the current position 700 and the travel route 710 can be confirmed through the displayed map, and the area 720 can also be confirmed.

[0046] FIG. 8 is a flowchart for explaining switching processing between a portrait screen and a landscape screen. First, it is determined whether or not the screen is AV (step S801). If the screen is not AV (Step S801: No), go to Step S805. If the screen is AV (step S801: Yes), it is determined whether the source is ON (step S802). If the source is ON! /, (Step S802: No), go to step S805.

[0047] If the source is ON (step S802: Yes), the screen is set horizontally (step S803).

That is, the display is arranged so as to be horizontally long. Here, it is determined whether or not the function is switched to navigation (step S804). If the navigation is not switched (step S804: No), the screen may remain horizontal, and the series of processing without changing the screen layout is terminated. [0048] When switching to navigation (step S804: Yes), the screen is set vertically (step S805). That is, the display is arranged so as to be vertically long. Here, it is determined whether or not the function is switched to AV (step S806). If not switched to AV (step S806: No), the screen may remain vertical, and a series of processing without changing the screen layout is terminated. On the other hand, when switching to AV (step S804: Yes), the process returns to step S803.

[0049] According to the embodiment described above, when a map screen such as a route search is to be displayed, the display screen can be arranged in the vertical direction, the map can be displayed in the vertical direction, and a general video can be viewed. If you want to, you can use the display screen in landscape orientation. As a result, normal images such as AV can be viewed as usual, while the map screen is displayed vertically, so that it can be displayed as a map screen in the direction of travel.

[0050] For example, when there is a point to be marked at the end of the travel route or when it is necessary to turn, it can be displayed earlier by increasing the length by making it vertically oriented. Therefore, it is possible to quickly know the information of the point displayed first. In other words, the user can expand the field of view when viewing the navigation screen without special processing such as enlargement or enlargement / reduction. In addition, it is possible to provide a screen display that is easy for the user to confirm.

Note that the navigation 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 recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD, and is executed by reading the recording medium force by the computer. The program may be a transmission medium that can be distributed through a network such as the Internet.
