Further, the hypertext interaction control means has an image processing means 4910 and a map control means with link 4911.

The operation of the hypertext display device configured as described above to display hypertext including map information will be described. When the user instructs the display of a new hypertext by using an input device 4901 such as clicking with a mouse by referring to a link or the like, the input control unit 4902 transmits the instruction to the hypertext interaction control unit 4909. Here, the instruction is http: //
Assuming that / host1 / page1 is displayed, the hypertext interaction control unit 4909 instructs the communication control unit 4906 to communicate with the host1 using the communication device 4905 because the reference destination of the hypertext data is on the external host1. The communication is performed to obtain the hypertext data page1.

Here, the hypertext data page1 will be described with reference to FIG. FIG. 72 is a schematic diagram showing an example of conventional hypertext data including a map. In FIG. 72, reference numeral 5001 denotes an example of an HTML document. <FORM> defines an operation specification when a user operation is performed. In this example, when there is a user input, / cgi-bin / index. It is defined to request acquisition of cgi. "Click the place you want to enlarge." Is a character string for display. <INPU
T> defines the specifications of an interface for user input. In this example, image data map.

When the user instructs selection of one point using the input device 4901 such as clicking with a mouse, the input control unit 4902 transmits the instruction to the hypertext interaction control unit 4909. Here, the instruction is 510
Assuming that the designation is in the vicinity of the Toyama-cho branch, the hypertext dialogue control unit 4909 instructs the map control unit with link 4911 to calculate coordinates to be added as an argument, and instructs the communication control unit 4906 to communicate with the communication device 49.

[0008] Further, the operation of the hypertext display device acquiring and displaying new hypertext data when the user selects one point on the enlarged map 5102 will be described. When the user performs an operation such as scanning the map using the input device 4901 such as moving the cursor with a mouse, the input control unit 4902 notifies the cursor position to the hypertext interaction control unit 4909, and the link-attached map control unit 4911 changes the cursor position. If the cursor position is on the link area, the user is notified of the existence of the link by changing the cursor shape or the like. Subsequently, when the user instructs selection using the input device 4901 such as clicking with a mouse, the input control unit 4902 transmits the instruction to the hypertext interaction control unit 4909. Here, assuming that the user designates the Toyama-cho police box of 5102, the hypertext interaction control unit 4909 instructs the link-attached map control unit 4911 to acquire the URL of pbox. htm, and the hypertext data pbox. htm is obtained and displayed.

As a conventional technique for automatically generating data as simple as possible when providing map data, a "generating system for a simplified map and its guidance for supporting route understanding" (Papers from the Institute of Electronics and Communication Engineers) Magazine Vol.J80-D-
11 No. 3 1997) and “Development of an Automatic Deformation Map Generation System” (Information Processing Society of Japan, Vol. 37).
No. 9 1996). The former discloses a technology for simplifying a map by using angle quantization and intersection movement from road network information. The latter discloses a technique of generating a simplified route diagram by performing omission or linearization based on block blocks.

[0010]

However, in the above-mentioned prior art system, since the map data is sent as image data, there is a problem that it cannot be displayed on a browser that can handle only text. Further, even if image data can be displayed, the image data is generally large in size, so that it takes a long time to use wireless communication with a low communication speed. Further, in a terminal such as a mobile phone or a smartphone that does not have a pointing device, the operation of selecting a link associated with a map cannot be simply performed. In the case of a server-side clickable map, the user cannot specify coordinates. In the case of a client-side clickable map, link destinations can be obtained by displaying a list of link destinations, but cannot be directly selected from the map.

With regard to the automatic generation of a schematic map, the current schematic map generation technology for a peripheral guide map has a variety of directions of link data on a map when a display area is widened. There is a problem that the number of cases where the map is not correctly reflected increases. In addition, in the current schematic map generation technology for route guidance, since a block diagram is generated by assembling a block, there is a problem that it becomes hard to see on one screen when the distance is long.

A first object of the present invention is to provide a hypertext display device and a system capable of displaying a map even with a browser that can only display texts.

It is a second object of the present invention to provide a hypertext display device and system which can reduce the time for data transfer in displaying a page including map information in browsing hypertext. .

[0014] A third object of the present invention is to provide a hypertext display device and a system which can easily operate a clickable map even in a terminal having no pointing device.

A fourth object of the present invention is to provide a hypertext display device which can dynamically provide a schematic map for a peripheral guide map with high accuracy even in a wide range and a schematic map for route guidance which is easy to see even over a long distance. Is to provide a system.

[0016]

SUMMARY OF THE INVENTION In order to solve this problem, the present invention firstly provides that a hypertext display device has rough map font data which is a set of rough graphic font figures. It is assumed that.

[0017] Thus, by expressing the map with the character code string of the approximate map font, there is an effect that the map can be displayed only by the text display function. Also, since the character code string has a smaller data amount than the map image data,

In the present embodiment, as a compression method, a method of expressing a 2-byte code string by a 1-byte code string only with an offset from a base 2-byte code (herein referred to as an offset expression), and a method of representing the same continuous code by 1 Two types, ie, a byte and a method represented by the code (herein referred to as run-length expression) are used in combination.
In FIG. 14, reference numeral 1401 denotes an example of hypertext data including map information in which the simplified map shown in 301 in FIG. 3 is represented by a compressed simplified map code sequence. CODEBASE = 0xf040 in the row of 1402 indicates that the code string originally in units of 2 bytes indicates an offset from 0xf040.
Declares that it is represented by a code string in byte units. COMPRESS = RLN declares that the code sequence is represented using a run-length representation. Here, reference numeral 1403 denotes a portion of the schematic map code string in units of 2 bytes in FIG. 3 represented by a code string in units of 1 byte by offset expression. For example &# 240 &#
114 (0xf072) is &# 50 (0x32).
# 240 &# 65 (0xf041) is &# 1 (0x1)
Is represented by Further, when a run-length expression is applied to 1403, a final code sequence of 1402 is obtained. In this case, the row &num; 1 &quot;
&# 131 &# 50 on line 06, && on line 1405

Next, while the hypertext display device of the present embodiment is displaying hypertext data including map information to which link information for equally divided regions is added, the hypertext data of the link destination is obtained by a key input by the user. The operation will be described. Upon receiving the key input event of the user via the input control unit 202, the hypertext interaction control unit 210 instructs the equal division map operation unit 213 to acquire the reference name of the link destination from the key operation link correspondence table, and perform communication control.

Although the example of the reference name of the hypertext data to be acquired as the link information has been described, a more flexible application can be provided by specifying a script or the like to be executed. Although only the example of the form of the client-side clickable map in which link information is included in the hypertext data has been shown, the same effect can be obtained in the form of the server-side clickable map in which the values of ROW and COL are transmitted to the server as arguments by key operation. The resulting system can be easily constructed. Also, an example of a method of directly corresponding the area and the key input has been described, but highlighting such as enclosing the area to be selected with a bold line, changing the selection with the arrow keys, etc.,

The peripheral outline map generating means will be described with reference to FIGS. 42 to 58. When the peripheral outline map generating means is activated (step 3700), when the area D is designated, the area D is cut out from the whole map in FIG. 43 (step 3701). The road α is rotated so as to be horizontal (step 3702), and a fine mesh is applied so that two or more link lines do not exist in one mesh (3901, FIG. 44, step 3703). The intersection A in FIG. 50 is moved to the center of the mesh. At this time, as shown in FIG. 51, intersections p, q,
r and s are fixed and move at the intersection (step 370)
4). An angle normalization process is performed on the link line connected to the intersection A in units of 45 degrees (FIG. 52, step 3).
705). The link line shape of the mesh adjacent to the intersection is modified so as to correspond to the intersection shape font with reference to Table 1 (FIG. 53, step 3706). An end flag is added to the intersection A to determine whether or not the processing for all the intersections on the target map has been completed. If the processing has not been completed, the process returns to step 3704, and if completed, the step 3708 is executed. In the embodiment, since there are still intersections a, b, and c, the process returns to step 3704 (step 3710). The intersections a, b, and c in FIG. 54 are moved to the centers of the respective meshes. At this time, if there is an intersection between eight adjacent meshes, the connected link line is moved. In this case, they are ab, bc, and ca (step 3704). In FIG. 55, the intersections a, b, and c are subjected to angle normalization processing in units of 45 degrees (step 370).

Step 3706). If there are no unprocessed intersections (step 3707), the connection relations of each intersection, i.e., ii, and wo are stored (3902 in FIG. 45), and the road link lines connecting the intersections are removed (step 3707). 390 in FIG.
3, step 3708). When the mesh is regarded as a matrix, each row and each column are all intersection areas (5 × 5 with the intersection at the center).
) And the landmark area (the landmark square) (row 3904 in FIG. 47), the row or column is removed (3904 in FIG. 47, step 37).
09). Restore the connection of intersections and connect them with straight lines (Fig. 4
8 3905, step 3710). A corresponding font is assigned from the intersection between the connected straight line and the boundary side of the mesh (step 3711). When the landmark and the square of the straight font overlap, the square of the landmark is shifted. In some cases, a font is synthesized (step 37).
12). As a result, map data 3906 in FIG. 49 is obtained. A schematic map code string is output by inserting a space or the like from data in the same format as in FIG. 38 (step 3713).

Therefore, it is possible to dynamically generate an easy-to-read schematic map code sequence representing a peripheral map according to a user's request. In addition, the processing result when there is no landmark in 3901 in FIG.
602.

In the present embodiment, the road width is not taken into account at the time of output from the rough outline map generating means. However, by increasing the number of font types representing roads and taking into account the road width at the time of output, the road width can be reduced. A simplified map code string generation device that expresses the difference can be easily realized.

As described above, according to the present embodiment, when the approximate map code string generation device inputs the display position and the display range in the map data in which the main road and other roads can be distinguished, First, the main road is deformed from the map data that can be distinguished from other roads, and the area surrounded by the main road is deformed while maintaining the coordinate position and the phase between the roads caused by deforming the main road. By providing a peripheral outline map generation unit and a font conversion unit for converting the generated outline map into an outline map code sequence, when an area to be displayed with information of coordinates or landmarks is input, an area to be displayed is first displayed.
