Embodiment approach 1

[0041] figure 1 It is a configuration diagram of the dynamic label placement device 1 according to Embodiment 1 of the present invention.

[0042] The dynamic label placement device 1 has a first label database 11 , a second label database 12 , a third label database 13 , a display information database 14 , a display information acquisition unit 15 , a label acquisition unit 16 , a position calculation unit 17 , and a label display unit 18 .

[0043] figure 2 It is a figure which shows an example of the recorded content of the 1st tag database 11. As shown in FIG.

[0044] The first tag database 11 stores a collection of tags whose positions can be changed according to changes in the display range, such as tags of roads and rivers. like figure 2 As shown, in the first label database 11 , images to be displayed (labels), roads, position coordinates (absolute coordinate system), and display availability are recorded for each label. Among them, the road attached to the lab...

Embodiment approach 2

[0142] In this second embodiment, an embodiment in which a specific tag is preferentially displayed will be described.

[0143] Figure 17 It is a configuration diagram of the dynamic label layout setting 1 according to Embodiment 2 of the present invention.

[0144] In addition, for the same configuration as that described in Embodiment 1, overlapping descriptions will be omitted. The difference between the dynamic label placement device 1 in Embodiment 2 and the dynamic label placement device 1 in Embodiment 1 is that it further includes a route information database 19 and a route information acquisition unit 20 .

[0145] The route information database 19 holds information on a route from the current position to a destination designated by the user.

[0146] The route information acquisition unit 20 acquires a route from the route information database 19 to the destination.

[0147] Figure 18 It is a block diagram of the position calculation part 17 in Embodiment 2 of ...

Embodiment approach 3

[0165] In the above Embodiments 1 and 2, the case where the dynamic tag configuration device of the present invention is applied to the car navigation system is described, but it is not limited to the navigation device of the car navigation system, and can also be applied to the navigation device including people, vehicles, railways, Navigation devices for mobile bodies such as ships and airplanes can also be applied to navigation system servers. In addition, it can also be applied to applications of navigation systems installed in portable information terminals such as smartphones, tablet PCs, and mobile phones, and can be applied to any form.

[0166] Figure 20 It is a figure which shows the outline|summary of the navigation system in Embodiment 3 of this invention. This navigation system can adopt various methods such as the following: the in-vehicle device 200 cooperates with at least one of the portable information terminal 201 such as a smartphone and the server 202 to...

Abstract

A dynamic label arrangement device comprises: a first label DB for storing a set of labels which can change its position corresponding to a change in a display range; a second label DB for storing a set of labels which does not allow a position change; a third label DB for temporarily keeping a label to be displayed on a display screen and the position of the label; a display information DB for storing the information required for displaying a label; a position calculation unit which identifies a label to be displayed on the display screen from among the labels stored in the first label DB and the labels stored in the second label DB and registers the identified label in the third label DB; and a label display unit for displaying the label registered in the third label DB. The position calculation unit determines a permissible arrangement range where a label can be arranged on the basis of a modifiable arrangement range offset stored in the display information DB, and modifies the arrangement of the label stored in the first label DB, which was excluded from the permissible arrangement range when the range of the display screen was modified.

Description

technical field [0001] The present invention relates to a dynamic tag arrangement device for arranging tags such as road names and building names on map displays such as car navigation. Background technique [0002] In the map display function of an existing car navigation system, etc., there is a function of displaying a character string label at a fixed position. In this function, due to the display range (hereinafter referred to as the display range), a part or all of the label is missing, and the readability deteriorates (refer to Figure 21 ). [0003] Therefore, there is disclosed a method of changing the position of a label to a position that is easy to see in accordance with a change in the display range on a 2D map (for example, Patent Document 1). In addition, a technique for displaying labels on a 3D map is also disclosed (for example, Patent Document 2). [0004] prior art literature [0005] patent documents [0006] Patent Document 1: Japanese Unexamined Pa...
