Problems solved by technology

[0007] In the multilingual document processing device disclosed in the above-mentioned Patent Document 1, there is a problem that since the language identification information is stored in each data, the amount of data becomes huge in a car navigation device that handles a large amount of data.
In addition, when the character string information for voice is processed in the map information processing device, there is a problem that, although the display character strings for male and female voices are the same, the data need to be stored separately, so the language type is different from the actual language. Ratio to increase, the amount of data that should be saved increases
[0008] In addition, regarding the method of using a single code as a character code in order to handle character strings in multiple languages, there is a problem that the amount of data

Embodiment approach 2

[0062] Embodiment 2. In the map information processing device according to Embodiment 2 of the present invention, at the end of the language type code table used by the map information processing device according to Embodiment 1, processor 15 stores The language category code (hereinafter referred to as the "terminal category code").

[0063] The terminal class code can be determined as follows. (1) An arbitrarily determined fixed value is set. Assume that the language corresponding to the fixed value at this time is arbitrarily determined from the country or region represented by the map data associated with the character information of the multilingual character information (for example, a common language). (2) The language category code corresponding to the language (such as common language, etc.) arbitrarily determined by the country or region represented by the map data associated with the character information of the multilingual character information is used as the ter...

Embodiment approach 3

[0067] Implementation mode 3. Figure 12 It is a block diagram showing the configuration of the map information processing device according to Embodiment 3 of the present invention. The map information processing device and figure 1 The map information processing device according to Embodiment 1 shown is the same, and includes an input device 11 , a map information storage device 12 , a position detection device 13 , an output device 14 , and a processor 15 .

[0068] Processor 15 in addition to including and figure 1 The map information processing device according to Embodiment 1 shown includes a character code recognition unit 25 in addition to the same language recognition unit 21 , character information acquisition unit 22 , and main control unit 24 . The character code recognition unit 25 recognizes character codes of the character information stored in the map information storage device 12 .

[0069] The map information storage device 12 stores character string data i...

Embodiment approach 4

[0072] Embodiment 4. The map information processing device according to Embodiment 4 of the present invention has the same configuration as Embodiment 3, but differs from the map information processing device according to Embodiment 3 in that it has a identifying information.

[0073] The character code identification information may be configured to create a table defined for each language as described in Embodiment 1, or to define one character code for each multilingual character information record instead of for each language. In addition, as described in Embodiment 1, the identification information of character codes may be stored in multilingual character information record units, or may be stored in each management unit of hierarchical map data. Also, a default character code can be specified as required.

[0074] For example, like the map information processing device according to Embodiment 3, it includes a character code recognition unit 25 that recognizes character...

Abstract

A map information processing device is provided with a map information memory device (12) that memorizes multiple language character information comprised of a language category code table storing language category codes indicative of language categories for every predetermined data management unit or every region unit made to correspond to each layer of layered map data and character information arranged to correspond to the language category codes stored at the language category code table, an input device (11) that designates a category of a language, a language identifying unit (21) that acquires the language category code table in accordance with the category of the language designated by the input device from the map information memory device and identifies the language of the character information based on the acquired language category code table, and an output device (14) that outputs the character information of the language identified by the language identifying unit.

Description

technical field [0001] The present invention relates to a map information processing device for processing map information in, for example, a car navigation device, and particularly relates to a technique for processing map information in multiple languages. Background technique [0002] As a device for processing information in multiple languages, Patent Document 1 discloses a multilingual file processing device that can distinguish and manage information related to multiple language files for each language, and can access each information quickly and easily. In addition, processing such as retrieval is performed at high speed. In this multilingual document processing device, indexes and the like of multilingual document data are stored and managed separately for each language. [0003] In addition, a conventional map information processing device applied to a car navigation device stores voice character string information for voice guidance. The format of the character s...
