Abstract

PURPOSE:To display even a space between pages serving as control units and to minimize the file capacity by synthesizing internally the maps adjacent to each other and using a display window that moves freely within the synthesized map. CONSTITUTION:A display memory 1 has an area large enough for a control unit 2 and the adjacent information 5 are internally retrieved and synthesized to the retrieved and displayed information 3. A display window 4 is moved freely within a synthetic map of both pieces of information 3 and 5 and synthesizes maps successively on a sufficiently large memory 1. Thus all maps can be displayed as if they were equal to just a single map. This eliminates the need to produce a map overlapping pages and therefore can minimize the file capacity.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic map search device for searching and displaying map information required, for example, in firefighting services. [Prior Art] Conventionally, this type of map search device uses an electronic filing system using optical disk files,
The map was displayed for each page of the map manuscript, which was a management unit.

[Problem that the invention seeks to solve]

In the conventional electronic map search device mentioned above, the management and display unit is one full page as shown in Figure 2, so if the measles disaster point is on the searched map, the disaster point is displayed in the center of the CRT. , it is not possible to view the situation (information) around the disaster point on the same display screen, so we have taken measures when creating the map manuscript to manage the creation of one duplicate map 6, as shown in Figure 3. However, this method has the disadvantage that as the number of overlapping areas increases, the file capacity required is several times that of the original map, making it uneconomical.

[Means for solving problems]

The electronic map search device of the present invention includes a display memory that stores a plurality of consecutive pages of a map manuscript as one large map;
The present invention is characterized by having means capable of displaying an arbitrary portion within the display memory.

In this way, by treating map information divided by pages as one large map through image processing, there is no need to create duplicate maps across pages, and the file size can be kept to the minimum necessary. be able to.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is an image synthesis processing model diagram showing an embodiment of the electronic map search device of the present invention.

This embodiment has a sufficiently large display memory l for the management unit 2, and for the retrieved and displayed information 3, the adjacent information 5
The 0 display window 4, which internally searches and synthesizes information, can be moved arbitrarily within the synthesized maps of information 3 and 5, and by sequentially composing them on a sufficiently large display memory 1, the entire map can be displayed as if It can be displayed as if it were a single map.

〔Effect of the invention〕

As explained above, the present invention internally synthesizes adjacent maps and uses a display window that moves arbitrarily within the synthesized map to display even the spaces between pages, which are management units. This eliminates the need to create duplicate maps that span multiple pages, and has the effect of keeping the file size to the minimum necessary.
