Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an information display device that outputs and displays information regarding facilities on a display device along with a map.

[Summary of the invention]

The present invention provides an information display device that digitizes map information, stores it in a predetermined storage medium, reads the map information from the storage medium, and displays the map information converted into an image signal on a display device.

Predetermined facilities such as parking lots, gas stations, and dealers are superimposed on the road at the location where the facilities exist.

In addition to displaying symbols, each symbol representing the same type of facility should also be displayed with five relatively simple numbers, symbols, etc. that are mutually distinguishable and consecutively related, thereby making the map difficult to read. This feature improves operability when obtaining the location of each facility and more detailed information.

[Conventional technology]

Recently, map information was recorded on a CD-ROM or the like.

Vehicle navigation devices that read the map information and display it on a display device together with the vehicle's current location to guide the vehicle to a predetermined destination are being researched and developed. Such conventional devices are used, for example, in hotels, parking lots, gas stations,
When there is a predetermined facility such as a car dealership, its name, etc. is displayed on a display device along with roads near its location for the convenience of drivers.

[Problem that the invention seeks to solve]

However, if the name of each facility and the road are always displayed on the display device in this way, the location of each facility can be known, but there is a drawback that the map itself becomes difficult to see. Also, since various facilities are displayed at the same time, you can
When searching for one facility, for example, a gas station, facilities other than the gas station are also displayed, so it takes time to distinguish and search for the gas station. Therefore, in order to ensure the legibility of the map, detailed information on each facility must be omitted, and conversely, in order to display more detailed information on each facility, the legibility of the map must be sacrificed. I had to.

[Effect]

The effect will now be explained. First, the basic operation when the navigation key 51 is operated will be explained. Direction sensor 7, speed sensor 8. The processor 10 calculates and detects the current location of the vehicle based on information from the GPS device 9 and the like. In response to this information, the processor 6
A map including the current location is read from the ROMI and stored in the memory 5. Maps of a plurality of scales are recorded on the CD-ROMI, and maps of each scale including the current location are stored in the memory 5. The processor 6 controls the controller 15 and causes data of a predetermined scale of the map stored in the memory 5 to be written in the memory 16 or 17. Memory 16.1
7, one side is the front side (the side where data is transferred to the memory 2o) and the other side is the back side (the side where the data is not transferred to the memory 2o and new data is written by the controller 15). The front side and the back side are switched alternately, and writing by the controller 15 is always done in the memory 20.
No data is sent to the backside.

The processor 6 further controls the controller 15 and stores the memory 16.1 in response to the current location signal from the processor 10.
Draw your own army mark on the front side of number 7.

The map drawn in the memories 16 and 17 by the controller 15 is obtained by converting data within a predetermined range centered on the own military mark from parallel data to serial data by the parallel/serial conversion circuit 18, and then converting the color signal into color. The color signal is converted into a high gradation color signal by the palette register 19 and transferred to the memory 20. Memory 16.1
Which portion of the map drawn in 7 is to be transferred is designated by the processor 6 via the offset register 22 and address counter 23.

The processor 6 is also capable of drawing a photograph of, for example, an intersection recorded on the CD-ROMI directly into the memory 2o as an image. The image written in the memory 20 in this way is further transferred to the memory 21, and the image finally stored in the memory 21 is transferred to the D/A conversion circuit 26.2.
7.28 to be output and displayed on the display device 29.

Next, the effect when the guide key 53 is operated will be explained.

When the guide key 53 is operated, the processor 6 displays a guide menu at a predetermined position on the display device 29 (near the top and bottom sides in the figure), superimposing it on the map, as shown in FIG. 4, for example.

Roads are now on CD ROMI as map information.

Assuming that not only line segment data showing railways, coastlines, etc., but also symbol data showing symbols of each facility such as hotels, gas stations, car dealers, and parking lots are recorded, these symbols are required. Accordingly, it is displayed at a predetermined position along with the characters that indicate its meaning.

Display device i? A touch sensor is placed on the front of the screen 29, and when you touch the display position of each facility with your finger, it is detected. Therefore, it is determined whether a hotel, parking lot, gas station, or dealer is selected, and when any facility is selected, the guide menu is cleared and the symbol of the selected facility is superimposed on the map. Displayed in your location. For example, when a hotel is selected, the fifth
As shown in the figure, hotel symbols are displayed corresponding to their locations on the map. This symbol is the same as the symbol displayed when the guide menu is displayed.

Therefore, the operator can almost intuitively select a desired facility by simply looking at the symbols without looking at the characters on the guide menu display. Also, since facilities that are not selected at this time are not displayed, searching for the symbol itself becomes extremely easy. Conversely, if the guide key 53 is not operated, only a normal map without these symbols is displayed, so the map does not become difficult to see.

Each symbol representing a similar facility is distinguishable from the other and
In addition, relatively simple numbers (numbers), characters, symbols, etc. that are continuously related are attached. That is, for example, the symbols of each hotel include numbers such as 1, 2, 3, etc., letters such as A, B, C, etc.
Other symbols are supported, and when a symbol is displayed superimposed on a map, this number etc. is also displayed.

The symbol is displayed at the location of the corresponding facility, so the symbol and number of a facility located outside the map centered on the current location displayed on the screen of the display device 29 will be displayed if the symbol and its number are located within the range of the screen. It will not be displayed until In the example of FIG. 5, the hotel numbered 2 is located outside the currently displayed map and is therefore not displayed. These numbers correspond to each hotel. At least within a given area, different hotels are never given the same number. Therefore, the user can specify a desired hotel using this number. Of course, the above also applies to other symbols.

When adding letters or the like to a symbol, it is also possible to use it as the name of the facility, for example. However, since the name makes the map difficult to read, it is not a simple character in the present invention.

As shown in FIG. 5, when the selected symbol is displayed superimposed on the map, a predetermined position of the display device 29 (near the lower right side in the embodiment) is displayed with the selected symbol. An operation switch for displaying more detailed information about the facility is displayed (in the embodiment, letters of a list are displayed).

Touch the area where the characters in this list are displayed with your finger.

When you touch it, it is detected by the touch sensor.

As shown in Figure 6, the map is erased from the screen of the display device 29, and in its place more detailed information regarding the hotels displayed on the map at that time is displayed as a list. More detailed information includes, for example, the name, telephone number, address, and characteristics of the hotel. Therefore, the operator can specify the desired hotel by its number in the display state shown in Fig. 5, then switch to the display shown in Fig. 6 and view the information in the area with the corresponding number. You can get more detailed information. At this time, information on facilities that are not displayed on the map is not displayed, making it easier to see information on the desired facility. Furthermore, by using something that has a continuous relationship, such as a number, it becomes easier to search for a desired facility from the list.

A flowchart for the processor 6 to execute the above operations is shown in FIG. 3, for example.

First, with the map displayed on the screen, wait until you are instructed to display a symbol. When display of a symbol is instructed, the position data (coordinates) of the symbol is read and it is determined whether it is within the range of the display screen (map). When the symbol is located within the range of the map being displayed, the symbol is displayed superimposed on the map.

Also, the number of the symbol is written into a predetermined stack of the memory 5. Symbols located outside the range of the displayed map will not be displayed and their numbers will not be written to the stack. After these steps have been performed for all facilities (symbols), wait until an instruction to display a list is given, and when the instruction to display a list is input, the number of the symbol stored in the stack in advance is read and its The data corresponding to the number will be displayed.

Figure 7 shows the symbol data of such a facility on a CD-ROM.
1 shows an example of the structure of position data in the case of recording in 1. In other words, a number within the same type of symbol and an attribute that distinguishes between symbols such as hotels, dealers, gas stations, parking lots, etc. are placed as headers, and then the coordinates (x + y) of the position where the symbol is displayed are placed. has been done.

FIG. 8 shows an example of the structure of a data block with more detailed information on each facility. That is, following the number of each symbol, data such as the facility's name, telephone number, address, characteristics, etc. are arranged.

FIG. 9 shows an example of the structure of the stack. The m number of the symbol displayed superimposed on the Sunanechi map is placed first,
After that, the number of that symbol is placed. For example, in the case of the embodiment shown in FIG. 5, the number of displayed symbols is three and the symbol numbers are 1, 3.4, so the stack data is as shown in FIG. 10.

Although the present invention has been described above by way of example in which it is applied to a vehicle navigation device, the scope of application of the present invention is not limited thereto.

〔effect〕

As described above, the present invention provides an information display device that digitizes map information and stores it in a predetermined storage medium, and displays the map information read from the storage medium and converted into one image signal on a display device. , parking lots, gas stations, dealers, etc. M! The crotch is displayed as a symbol superimposed on the road at the location where the facility is located, and each symbol representing the same type of facility is marked with a relatively simple numeric character that is mutually distinguishable and continuously related. ,
Since symbols, etc. are displayed together, facilities can be distinguished by their numbers, etc., and more detailed information can be displayed separately in correspondence with the numbers. As a result, there is no need to display facility names, etc. on the map in the normal state, and it is possible to prevent the map from becoming difficult to read. As a result, the location of each facility and more detailed information on that facility can be independently confirmed, and operability can be improved.
