Abstract

PURPOSE:To easily add postscript information to map information to be displayed by overlapping the postscript information inputted from an operation input terminal and stored for a while on the map information stored for a while in a display memory to be retrieved and read. CONSTITUTION:The map information of an area retrieved in a retrieval procedure from many pieces of map information is position-designated to a display memory 2, developed and temporarily stored. The postscript information inputted from the operation input terminal is temporarily stored in a storing means such as a random access memory 6. Consequently, the postscript information stored into the storing means 6 can be overlapped on the map information developed to the display memory 2 by a means to select the position of the information like a mouse 7. Thus, data information to the map can be easily added and deleted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention is applied to a map search device that uses an optical disk as a recording medium for map information. It is particularly suitable for use in a navigation device that can easily add additional information to a displayed map image.

〔overview〕

The present invention provides a map search device that records map information on an optical disk, in which additional information input from an operation input terminal and temporarily stored is searched and read out and added to the map information temporarily stored in a display memory.
By overlapping, additional information can be easily added to the displayed map information.

[Conventional technology]

Conventionally, this type of map search device has performed a search process for only map information. Therefore, necessary additional information on the map must be re-entered after changing the stored contents of the map information.

[Problem that the invention seeks to solve]

Therefore, the above-described conventional map search device has a drawback in that it cannot easily process additional information required on the map.

SUMMARY OF THE INVENTION An object of the present invention is to solve this drawback and provide a map search device that uses an optical disk as a map information recording medium and can easily process additional information.

[Means for Solving the Problems] The present invention provides an optical disc playback device, a display memory that temporarily stores retrieved map information recorded on the optical disc, and a display device that displays the contents of the display memory. and,
In a map search device comprising an operation input terminal and a control means for changing and controlling the contents of the display memory, the control means comprises:
The present invention is characterized in that it includes a storage means for temporarily storing additional information on the map inputted from the operation input terminal, and means for recording this additional information in the display memory in a superimposed manner on the map information.

[Effect]

The map information of the area searched by the search procedure from a large amount of map information is respectively designated, expanded, and temporarily stored in the display memory. The additional information inputted from the operation input terminal is temporarily stored in a storage means such as a random access memory. Therefore, by means of selecting the position of information such as a mouse, the additional information stored in the storage means can be superimposed on the map information developed in the display memory, and the map information and additional information are overlapped on the screen of the display device. will be displayed.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of an embodiment of the present invention.

The device of this embodiment includes an optical disc playback device 1, a display memory 2 that reads and temporarily stores map information recorded on the optical disc IA according to a search procedure, and a display device 3 that displays the contents of the display memory 2 on a screen. , a keyboard 4 which is an operation input terminal, and a control section 5 which includes a read-only memo 1J5A in which the above-mentioned search procedure is stored and changes and controls the contents of the display memory 2 according to input information from the keyboard 4.

Here, the present invention is characterized by a random access memory 6 which is a storage means for temporarily storing additional information on the map inputted from the keyboard 4 as a control means, and a random access memory 6 which is a storage means for temporarily storing additional information on the map inputted from the keyboard 4, and a random access memory 6 which is a storage means for temporarily storing additional information on the map inputted from the keyboard 4; The present invention is equipped with a mouse 7 for overlapping recording.

FIG. 2 shows a flowchart of the operation of this embodiment.

Next, the operation when this embodiment is applied as a navigation device will be explained.

A large amount of map information is recorded on the optical disc IA, and its search procedure is stored in advance in the read-only memory 5A. A map of Town B in City A is specified from among the above-mentioned large number of map information by operating the keyboard 4 according to the above-mentioned search procedure. At this time, if goods are to be delivered to addresses C, D, and E in Town B, the symbol indicating the destination point must be entered on the keyboard in accordance with the location of the lot number, and the symbol must be entered on the keyboard in accordance with the map of the B Town section. The information is stored in the display memory. When actually delivering goods to each number, if you want to add a circle mark to the place where the delivery was successful and a triangle mark to the place where the delivery is impossible because the consignee is absent, use the following procedure. conduct. When the delivery at address A is completed, a circle mark input operation is performed from the keyboard 4, and the information of this circle mark is stored in the random access memory 6.

Next, by operating the mouse 7, the circle information stored in the random access memory 6 is superimposed on address A in the map information. This overlapping operation is easy because it overlaps the map information stored in the display memory 2 with the contents of the random access memory 6.

〔Effect of the invention〕

As explained above, according to the present invention, data information can be easily added to or deleted from a map.
