Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a reproducing apparatus for an information recording carrier on which image information is completely recorded.

[Conventional technology]

In compact discs currently on the market, audio signals are recorded as the information signals. Of course, since the audio signal is an analog signal, the disc circle contains this analog signal 'tAD conversion (Analog to AD conversion).
I] Digital conversion) The signal is digitized after digital conversion and recorded as an fc signal. It is clear that a compact disc can reproduce video information if a signal obtained by digitizing an audio signal and using a signal obtained by digitizing a video signal system instead of a signal obtained by digitizing an audio signal is used as the digitized signal. Digitizing video information means, for example, converting a TV screen into a vertical 200. Divided into 256 horizontal small sections, each section has address information and R, G, B.
This can be easily done by providing color information (Red, Green, Blue) in t-3 pits or 4 pits. A compact disk that records image information in this way is sometimes called a t-CD-ROM.
Hereinafter, it will be referred to as CD-ROM for convenience.

Now, such image information can be used as map information and as a guide map while driving a car. It is a navigation system.

An example of the navigation system will be explained using FIG. 2. For example, consider the case of going to a human site pD point on the map. First, the map information shown in the CD-ROM0M map is read out and displayed on the screen of, for example, a TV. The location on the screen can be easily identified because address information is attached to all of the small sections. If absolute latitude and longitude information on the earth is given for one point on one screen, for example, the lower left corner indicated by X, then all the latitude and longitude on one screen can be determined. Naturally, this latitude and longitude information is also written on the CD-ROMjl'E along with one piece of map information. Since the navigation system allows you to know the absolute latitude and longitude position of your vehicle using the entire geomagnetic field or satellite data, you can easily show the entire location of your vehicle on the currently displayed map information screen. This craft sea urchin CD-ROM? The user navigation system can automatically show the location of the user's vehicle on one screen, which is very convenient for driving.

Conventional equipment #: All shown in Figure 3. The information signal recorded on the CD-ROM is reproduced by the CD-ROM driver,
After this information signal is stored in a single memory 2, it is separated into image information and address information and input to an image processing circuit 3. For example, an image display device 4 such as a TV is connected to the image processing circuit 3.
The two types of signals are processed in a form suitable for the purpose of the present invention, and after t, are sent to the display device 4 for one image per image. On the other hand, the sentence position information and the address information detected by the own vehicle position detection device 5 are input to the address information calculation circuit 6, and the circuit 6 compares the position of the own vehicle with the position on the map. The own vehicle position information is input to the image processing circuit 3 to be displayed on the image display g&place 4. In the image processing circuit 3, the image information and the wheel position information are added together and displayed on the image display device 4. This sea urchin,
This system automatically displays the vehicle's location on the map, which is very convenient.

[Problem that the invention seeks to solve]

However, even with this convenient system, there are still other inconveniences. For example, consider a case where you go to an unfamiliar city for the purpose of sightseeing. In this case, there are several routes to the destination, and it is difficult to immediately determine which route is the closest or safest. Also, there are so many things to be careful about when you reach a point where you can't move forward, so you might be wrong.

Furthermore, there are problems such as entering one-way streets when trying to take the shortest route. Also, there are times when you set off without fully researching what to see at a tourist spot, but if you do not do so, your destination may become unclear, and your driving may become erratic, causing a nuisance to other vehicles. , which was not desirable from a safety standpoint.

The invention was made to solve all the problems mentioned above.
To provide an information recording carrier reproducing device which can reach a destination by selecting all optimal routes even if driving all the way in a new city.

[Means for solving problems]

The information recording carrier reproducing device according to the present invention records all search information in addition to address information and image information on the information recording carrier, and reads the information from the information recording carrier when the address with the search information matches the door slot position. All the road information obtained will be displayed on an appropriate display means.It is a friend of mine.

[For production]

Search information is recorded at addresses that correspond to key points in the vehicle's route, and when the exit car arrives at a position that matches the address, road information such as parent guide information and one-way street information is displayed based on the search information. The information is read out and displayed on all display means to notify the driver.

〔Example〕

An embodiment of the present invention will be described below with reference to all the drawings.

In FIG. 1, reference numeral 21 denotes a search information extraction circuit, and 22 a CD-ROM driver l, which uses all the outputs of the search information extraction circuit 21 to search all parts of the CD-ROM in which desired tourist guide information is recorded. Search command circuit that issues commands%
Reference numeral 23 denotes a memory α (second memory) for storing all of the tourist guide information that is read out during this search process, and 24 is an audio processing circuit that converts all of the tourist guide information stored in the memory α 23 into a signal that can be expressed as audio. , 25 is a back voice display device that converts the output of the audio processing circuit 24 into all sounds. The other four positions are the same as before. Also, CD-R
The search information is omitted to the OM as shown in Figure 4. Address information A is a set of address information B and search information C, for example, 25
6×200 sets are recorded. This search information is actually an important address, such as intersection B shown in Figure 5.
, Cj=- It is assumed that the building is a famous tourist spot or is located on the road that passes through the front of E. For example, each point B
,C.

Search information for D and E? 001.002.003゜00 respectively
Set it to 4. The tourist guide at this time is, for example, the one at point B, and the contents extracted in the search information 001 are "
At points J and C, where E is located if you go straight, the answer is, ``If you turn left, in how many meters will you find D?'' Of course, this information is given slightly before entering the intersection, and the address information is chosen so that it can be distinguished in the direction of travel. Also, the sightseeing guides at points D and E are naturally related to the sightseeing points.

Next, the operation of the above device will be explained. Image display device! [The map information display and vehicle position display in 4 are the same as before, so theory 11! 111'! abbreviated to -Tan,
Among the information signals stored in the memory (first memory) 2, search information is input to the search information extraction circuit 21. Further, the match 1# information is inputted to the circuit 21 from the address information calculation circuit 6. This matching information means that the location of the vehicle calculated by the address information calculation circuit 6 matches the address on the map where the search information is located, for example, the addresses shown in FIG. 5, B, C, D, and E. This is information indicating. This - number information? In response, the search information extraction circuit 2■ extracts the search information of the address, for example, “00
