Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image display device and the like for displaying images, and more particularly to an image display device and the like for displaying images using a plurality of displays.

[0002]

2. Description of the Related Art In recent years, GPS (Global
Positioning System (Global Positioning System) A navigation device that can obtain its own position and moving speed in real time using a satellite is becoming widespread for mounting on a mobile body such as an automobile or for portable use. In this type of navigation device, a map is displayed on a monitor based on digitized map data.

Further, the navigation device has a function of setting a route from a departure place to a destination. When a user sets a route, at least a departure place (start point) and a destination place (end point) are designated. Then,
The navigation device searches for and generates an optimum route connecting two points of the designated starting point and destination and presents it to the user as a recommended route. In addition, the user can arbitrarily designate a point that he or she wants to drop in before arriving at the destination or a point that serves as a landmark during traveling, such as an intersection, an interchange, or a ramp, as a transit point. At this time, it is possible to designate a plurality of points as transit points. In this way, when the user specifies a waypoint, the navigation device searches for an optimum route connecting the departure point, one or more waypoints, and the destination. Further, even when the user does not particularly specify the waypoint, when the navigation device presents the recommended route to the user, the point located between the departure place and the destination should be presented to the user as the waypoint. You can also As a result, the user can grasp the image of the route and the guide point before departure.

[0004]

However, in the conventional navigation device, for example, when an enlarged map is displayed to see the details of the road around the current position of the set recommended route, the entire map displayed on the screen is displayed. The display area of is narrowed and you cannot see the entire recommended route.On the other hand, if you display a wide area map to see the entire recommended route, the map displayed on the screen is too rough and you can see the details of the road around the current position. There was a problem of disappearing.

Further, although it is possible to grasp the situation of the recommended route by scrolling the map using a remote controller or the like, in the case of a vehicle-mounted type, a scroll operation is performed during driving, so that driving is not possible. There was also the problem of causing trouble.

The present invention has been made to solve the above technical problems, and an object thereof is to provide an image display device or the like in which information can be easily obtained visually.

Further, on each side surface of the sub monitor 71, the pins 7 are provided at the same intervals as the expanding portion 66 provided on the main monitor 61.
4 (specifically, 74a and 74b) are attached. The interval of the pins 74 corresponds to the expansion portion 66 of the main monitor 61, and is made different in the vertical direction and the horizontal direction of the sub monitor 71. Further, at the center of each side surface of the sub monitor 71, a sub side connector 75 (specifically, 75a to 75d) connected to the main side connector 67 of the main monitor 61.
Is attached.

FIG. 5A shows an example in which the sub-monitor 71 is attached to the main monitor 61, and the main-side connector 67a of the main monitor 61 is connected to the sub-side connector 75c of the sub-monitor 71. Also, FIG.
5B is a sectional view taken along line Vb-Vb of FIG.

Next, the operation of the navigation device according to this embodiment will be described. In the control device 11, the current position is accurately grasped based on various information obtained from the sensor 13. Here, when the user specifies a route search via the input device 12, the input information processing unit 51
Then, for example, the user is prompted to input the destination via the output device 14. The input information processing unit 51 recognizes the destination input from the input device 12, is read via the map information reading unit 52, and is processed by the map information processing unit 53 and processed by the traffic information processing unit 56. The recommended route processing unit 54 calculates a recommended route from the processed traffic information. Then, the screen drawing processing unit 55 generates map data including the recommended route and displays it on the output device 14.

FIG. 7 shows the flow of processing until a map is displayed on the output device 14. First, the main monitor 61
It is determined whether or not the sub monitor 71 is attached (step S101). This determination is made based on whether or not there is a connection signal generated by the connection between the main side connector 67 and the sub side connector 75. Then, when the sub monitor 71 is attached to the main monitor 61, it is next confirmed which part (upper, left, right) of the main monitor 61 the sub monitor 71 is attached (step S102). It should be noted that the confirmation of the mounting portion of the sub monitor 71 is performed based on the connection signal described above.

When the mounting position of the sub monitor 71 is confirmed, the movement amount detecting units (encoders) 64, 73 mounted on the mounting positions of the main monitor 61 and the sub monitor 71.
Is cleared and the initial value is set to "0" (step S104). Then, the map is displayed on the main display portion 62 of the main monitor 61 and the sub display portion 72 of the sub monitor 71 (step S105). At this time, a map (sub map) continuous with the map (main map) displayed on the main display unit 62 is displayed on the sub display unit 72. Here, FIG. 8A shows a map display example when the sub monitor 71 is mounted on the upper part of the main monitor 61. In this example, the main display section 62 of the main monitor 61 is
A main map including a departure point 81 and a part of the recommended route 82 is displayed in the sub-display section 72 of the sub-monitor 71.

After the map is displayed on the main display section 62 and the sub display section 72, when the movement of the sub monitor 71 by the user is detected (step S105), the counters of the movement amount detection sections (encoders) 64 and 73 are measured. (Step S106), the relative distance (moving distance) between the main monitor 61 and the sub monitor 71 is calculated based on the measured counter value (step S107). Then, the sub-display 72 displays the sub-map moved by a distance corresponding to the calculated relative distance while maintaining continuity with the main map displayed on the main monitor 61 (step S108). . That is, the sub map displayed on the sub display unit 72 changes in association with the movement of the sub monitor 71. Here, FIG. 8B shows a map display example when the sub-monitor 71 is moved to the left side in the figure with respect to FIG. In this example, by moving the sub monitor 71, a sub map including the recommended route 82 to the destination 83 is displayed on the sub display unit 72, and the recommended route is combined with the main map displayed on the main display unit 62. It becomes possible to confirm the whole 82.

On the other hand, if it is not confirmed that the sub monitor 71 is attached to the main monitor 61 in step S101, the map is displayed only on the main display portion 62 of the main monitor 61 (step S109).

In the present embodiment, the user manually moves the sub monitor 71, but the present invention is not limited to this, and a stepping motor or the like is used so that the entire recommended route 82 is displayed. Alternatively, the sub monitor 71 may be moved.
