As shown in FIG. 4, the image setting screen displays a pull-down menu for allowing the user to specify the type (for example, manufacturer, vehicle type, color) of the image data of the vehicle to be acquired. The display method can be selected from still images and moving images. The CPU 61 provides the image data of the type (for example, manufacturer, vehicle type, color) and display method (still image / moving image) selected by the user on the image setting screen via the network N by the communication unit 2. Request to device 200. In response to this request, the image data of the vehicle is transmitted from the information providing apparatus 200 via the network N and received by the communication unit 2.
On the other hand, when acquiring vehicle image data from the storage medium 51 loaded in the loading unit 5, the CPU 61 accesses the storage medium 51 and reads the vehicle image data stored in the storage medium 51. When the vehicle image data read from the storage medium 51 includes a background image, image processing for extracting a vehicle portion from the image data is performed.
The CPU 61 functions as an acquisition unit together with the communication unit 2 by executing the acquisition program 64b.

The image adjustment program 64c is, for example, a program for causing the CPU 61 to realize a function of adjusting the vehicle image data acquired by executing the acquisition program 64b to a predetermined size.
Specifically, when the CPU 61 acquires the image data of the vehicle from the storage medium 51 loaded in the information providing apparatus 200 connected to the network or the loading unit 5 by executing the above-described acquisition program 64b, the acquired image data The image size and the like are adjusted with respect to the image and displayed on the image setting screen.

Specifically, by executing the above-described image adjustment program 64c, image adjustment such as image size is performed on the image data acquired from the information providing apparatus 200 or the storage medium 51, and the transparency is selected by the user on the image setting screen. When the command button for registering an image is pressed, the CPU 61 stores the image data that has been subjected to the image adjustment in the image registration memory 6322 together with data such as the transparency of the set image, and stores the image data. sign up.
The CPU 61 functions as a registration unit together with the image registration memory 6322 by executing the registration program 64d.

The route search program 64e is a program for causing the CPU 61 to realize a function of searching for a route, for example.
Specifically, the user performs a pointing operation on the map displayed on the display unit 3 or an input of a facility name, an address, and the like by the input unit 4, and the departure place (for example, the current position), the destination, the waypoint, etc. And instruct route search. When a route search is instructed by the user, the CPU 61 starts a route search to the set destination. As the route search method, a conventional Dijkstra method or a method equivalent thereto is used.
When the CPU 61 calculates a route to the destination using the Dijkstra method or the like, the CPU 61 stores route search information related to the calculated route in a predetermined area such as the memory unit 63 and the route to the destination based on the route search information. Guidance will be given.

The intersection approach detection program 64f, for example, determines to the CPU 61 that the vehicle on which the navigation device 100 is mounted enters the intersection based on the current position and route guidance information detected by the execution of the current position detection program 64a. It is a program for realizing the function to detect at the timing.
Specifically, when the CPU 61 performs route guidance based on the route search information of the route searched for by the execution of the route search program 64e, the CPU 61 automatically detects the route search information and the current position detection program 64a. Based on the current position of the vehicle and the map information read from the map information DB 6321, there is an intersection that is scheduled to pass within a predetermined distance range (for example, within 50 m) of the vehicle on which the navigation device 100 is mounted. Is detected.
The CPU 61 functions as an intersection approach detection unit by executing the intersection approach detection program 64f.

The route guidance display control program 64g, for example, causes the CPU 61 to superimpose on the map information on the display unit 3 the route guidance information for guiding the traveling route by the vehicle image based on the vehicle image data registered by the execution of the registration program 64d. It is a program for realizing the function to be displayed. Specifically, the route guidance display control program 64g displays the information on the display unit 3 when it is detected by the execution of the intersection approach detection program 64f that a vehicle on which the navigation device 100 is mounted enters the intersection. The intersection map information is displayed, and the vehicle image is displayed as a translucent image superimposed on the intersection map information.
The CPU 61 functions as a route guidance display control unit by executing the route guidance display control program 64g.

Specifically, when the intersection planned to pass is detected within the predetermined distance range (for example, within 50 m) of the vehicle by executing the above-described intersection detection program, the CPU 61 reads the road at the intersection from the map information DB 6321. Data indicating the width, shape of the road, number of lanes, direction of travel of each lane, buildings in the vicinity of the intersection, etc. are acquired, and based on these, the situation in front of the vehicle viewed from the position of the driver's seat is expressed A three-dimensional three-dimensional image (map information) is generated according to the situation near an actual intersection.
Further, the CPU 61 reads the vehicle image data registered by the execution of the registration program 64d from the image registration memory 6322, and superimposes the vehicle image based on the read vehicle image data on the generated three-dimensional image of the intersection. To be displayed on the display unit 3. The vehicle image is displayed by the display method (that is, still image / moving image) of the image data selected by the user on the image setting screen.
At this time, the CPU 61 expresses a state in which the vehicle passes through the intersection by superimposing the vehicle image on the three-dimensional image of the intersection along the traveling route on which the vehicle is to be guided. The image is displayed with the transparency of the value set by the user on the image setting screen (for example, the transparency is 50%).
In the present invention, “semi-transparent” does not refer to a transparency of 50%. For example, even if the transparency is 20% and the transparency is 80%, it can be translucent.

FIG. 6 shows a route displayed superimposed on the map information displayed on the display unit 3 when the route guidance display control program 64g is executed when the display method of the image data selected by the user is a still image. It is an example of guidance information.
As shown in FIG. 6, the display unit 3 displays two pieces of map information: a plane image of an intersection whose guidance route is indicated by an arrow, and a three-dimensional image of an intersection whose guidance route is indicated by a vehicle image. The three-dimensional image of the intersection is an image created based on the road width, the shape of the road, the number of lanes, the traveling direction of each lane, the buildings existing around the intersection, and the like read from the map information DB 6321, The situation in front of the vehicle seen from the driver's seat is reproduced. And on the said three-dimensional image, the still image data of the vehicle which the user registered is made translucent, and is continuously displayed along the advancing path which should guide a vehicle. That is, as shown in FIG. 6, a plurality (for example, four in FIG. 6) of still image data is gradually reduced in image size and gradually shifted in the traveling direction along the traveling path in the three-dimensional image. It appears as if the vehicle is passing through an intersection (for example, turning right in FIG. 6).
By viewing such a three-dimensional image of an intersection, the user can recognize at a glance, for example, that he / she should go straight / right / left, and at which intersection he / she makes a turn. In addition, since the vehicle image is a semi-transparent image, roads and objects that overlap the vehicle image are not hidden and can not be seen, and the overlapping part with the vehicle can be seen with certainty, and the traveling route can be grasped more. This makes it easier to grasp the situation around the intersection. Furthermore, the route guidance information is rich in preference because it guides the traveling route from the vehicle image desired by the user.

The image data of the vehicle is acquired from the information providing apparatus 200 via N, and the image data of the vehicle acquired by the execution of the acquisition program 64b is adjusted to a predetermined size by the execution of the image adjustment program 64c, and the registration program The image data of the vehicle acquired by executing the acquisition program 64b and adjusted by executing the image adjustment program 64c is registered by executing 64d, and registered by executing the registration program 64d by executing the route guidance display control program 64g. Based on the vehicle image data The route guidance information for guiding the traveling route by the vehicle image is superimposed on the map information and displayed on the display unit 3, and the current position detected by the execution of the current position detection program 64a by the execution of the intersection approach detection program 64f and Based on the route guidance information, it is detected at a predetermined timing that the vehicle on which the navigation device 100 is mounted enters the intersection, and the route guidance display control program 64g executes the intersection entry detection program 64f. When it is detected that the mounted vehicle enters the intersection, the map information of the intersection is displayed on the map information, and the vehicle image is displayed as a translucent image superimposed on the map information of the intersection. .
Therefore, the route guidance information for guiding the traveling route from the vehicle image is displayed on the display unit 3, and the navigation device 100 can provide route guidance information rich in taste. Specifically, when a vehicle enters an intersection, map information of the intersection is displayed on the display unit 3 and a vehicle image is displayed superimposed on the map information. The guidance information can be rich in taste.

  In addition, since the vehicle image is displayed as a translucent image, a road or an object is not obstructed by the vehicle image, and a portion overlapping the vehicle image can be surely seen, so that the traveling route can be easily grasped. .
