Abstract

PURPOSE:To prevent the data quantity of the coordinates for managing image information from increasing more than needed by providing the inside coordinates for managing code information in horizontal and vertical directions further in details with the block coordinates as the origin in accordance with the block coordinates. CONSTITUTION:The block coordinates manage the image information in the horizontal and vertical directions in the prescribed block unit and the inside coordinates manage the code information together with the block coordinates in the horizontal and vertical directions further in details with the block coordinates as the origin. For example, a frame memory writing section 9 writes the image of the block in the display block component transferred from an optical disk reading section 3 and the images of the inside coordinates of the display block component and the codes indicated by the kinds of the codes corresponding to the inside coordinates from the magnetic disk device 8 read by a magnetic disk device reading section 7, respectively into a frame memory 10. Both the images are superposed and displayed on a display 11. The data quantity of the coordinates to manage the image information is prevented from increasing more than needed in this way.

Description

[Problem to be solved by the invention]

In the conventional map search device described above, the coordinates for managing the map as image information and the coordinates for managing the symbols on the map as code information are the same. In map No. 1, it is sufficient to manage sections of about 50m" as the minimum unit in order to extract an arbitrary destination point, but when managing code information, it is necessary to manage the coordinates of about 5m". Because precision is required, the image information is also 5m! The problem is that the coordinates are managed with a degree of precision, and the amount of coordinate data for managing image information increases more than necessary.

Also, even if you want to add code information management to a map search device that initially managed only image information,
There is a drawback that the coordinates of already stored image information cannot be used as coordinates for managing code information because the precision of the coordinates is different.

In view of the above-mentioned points, an object of the present invention is to prevent the amount of coordinate data for managing image information from increasing, and to enable management of code information to be easily added later even when only image information is being managed. An object of the present invention is to provide a map search device.

[Means to solve the problem]

The map search device of the present invention stores the map as image information and the symbols on the map as code information and displays them superimposed on a display.
Section coordinates for managing image information horizontally and vertically in units of predetermined sections, and inner coordinates for managing code information in more detail horizontally and vertically with the section coordinates and the section coordinates as the origin. exists.

[Effect]

In the map search device of the present invention, the block coordinates manage image information horizontally and vertically for each predetermined block, and the inner coordinates manage the code information together with the block coordinates in more detail in the horizontal and vertical directions with the block coordinates as the origin. to be managed.
