Problems solved by technology

However, in the prior art, there is a problem that it is not easy to intuitively grasp which area the area displayed on the detailed map corresponds to in the wide area map.
In addition, there is a problem that the vehicle mark indicating the position of the vehicle is displayed on both the detailed map and the wide-area map, so that a sense of incongruity arises.

Embodiment approach 1

[0050] A car navigation system to which the display device of the present invention is applied is installed, for example, in a dashboard of a vehicle or at a position on the dashboard where the driver can easily observe. The car navigation system performs route search, route guidance, and display of routes and maps by obtaining the position of the vehicle or inputting a destination by the user, and displays the entire route on the display by having the display device of the present invention.

[0051] figure 1 It is a diagram showing the configuration of a car navigation system 1a including a display device 100a according to Embodiment 1 of the present invention.

[0052] The car navigator 1a has a setting storage unit 2 for storing display settings, a route storage unit 3 for storing a set route, a position detection unit 4 for detecting the position of the vehicle, a map storage unit 5 for storing a map, and a storage unit for storing a display. The display area storage uni...

Embodiment approach 2

[0166] In Embodiment 1, a wide-area map containing all routes is generated from the detailed map. The display device 100b of Embodiment 2 is different in that, as Figure 13 to Figure 19 The intermediate map generation unit 200 shown is provided. The intermediate map generation unit 200 provides an intermediate map connecting the detailed map and the wide-area map on the basis of the detailed map and the wide-area map. The intermediate map generating unit 200 connects the intersection of the boundary and the path between the detailed map and the intermediate map and the intersection between the boundary and the path between the wide area map and the intermediate map using deformation such as a straight line or a curve in the area where the intermediate map is displayed. The configuration of the wide-area map generation unit 500 b also differs from that of Embodiment 1 in connection with the provision of the intermediate map generation unit 200 . Other than that, the display d...

Embodiment approach 3

[0226] In Embodiment 1, the detailed map and the wide-area map are connected by a boundary between the detailed map and the wide-area map so that all routes converge. The display device 100c of Embodiment 3 is different in that, as Figure 20 ~ Figure 26 As shown, on the basis of the structure of Embodiment 1, the map effect generation unit 408 having the extension effect of the generated map displays the display information of the detailed map in the area connecting the area where the detailed map is displayed and the area where the wide-area map is displayed. At least a portion of overlaps an adjacent wide-area map. Here, the configurations of the detailed map generation unit 400c and the wide-area map generation unit 500c are also different from those in the first embodiment along with the provision of the map effect generation unit 408 . Other than that, the display device 100c is the same as that of the first embodiment. According to these configurations, for example, n...

Abstract

One problem involving conventional display apparatuses is that the entirety of a route cannot be confirmed in a single view because the entirety of the route is not always displayed when maps of different scales are simultaneously displayed on the same screen. This display apparatus (100a) is provided with: a first display information generation unit (400a) that generates first display informationfor displaying, in a first region, a first map and a first route including a first position and the first region; a second display information generation unit (500a) that calculates an intersection point between the boundary of the first region and the entirety of the route, calculates a tangent region in which a second route connecting a second position and the intersection point is fitted in tangent, determines a scale that allows the tangent region to fit inside a second region including the second route and that allows displaying of the first route and the second route so as to be connected at an intersection point, and generates second display information for displaying, in the second region, the second route and a second map in the scale; and a display control unit (103) that controls displaying, on a display unit (101), the first display information and the second display information in a synthesized manner.

Description

technical field [0001] The present invention relates to a display device for displaying a route on a map. Background technique [0002] For example, a car navigation system (hereinafter referred to as "car navigation system") mounted on a vehicle has a display device for displaying a route on a map. [0003] In a car navigation system, for example, it is assumed that a driver sets a route, and the driver travels on a road according to the route set on a map displayed on a display unit of the car navigation system. In the map to be displayed, in order to easily associate roads in the real world with roads on the map, it is necessary to display in detail the roads being driven, the angles and shapes of roads connected to the roads being driven, and which side to view from left and right. The positional relationship between the shops existing along the way and the distance between the shops and the shops along the way. Therefore, for example, it is preferable to display the p...
