Then, the spot name information acquisition unit 146 determines whether or not the attribute acquired for each spot name information satisfies a predetermined condition. And the spot name information acquisition means 146 acquires the spot name information which satisfy | fills the said conditions from the said spot name information.

  The predetermined condition is a condition related to the attribute of the point name information. For example, it is less than a certain number of characters, more than a certain number of characters, less than a certain number of times of selection, and the number of times of selection. It is more than a certain number of times. Moreover, although the said conditions are normally hold | maintained by the point name information acquisition means 146, the attribute acquisition means 145 may hold | maintain. In addition, the condition may be stored in an arbitrary storage area, or may be included in the acquisition reference designation instruction.

  Further, the spot name information acquisition unit 146 may sort the spot name information acquired as described above based on the information used when acquiring the spot name information. For example, when the location name information is acquired using the distance, the location name information acquisition unit 146 sorts the acquired location name information in the order of the closest distance. Further, for example, when the spot name information is acquired using the area information, the spot name information acquiring unit 146 sorts the acquired spot name information for each area indicated by the area information. Further, for example, when the point name information is acquired using the matching condition, the point name information acquiring unit 146 indicates the index value indicated by the matching condition for each matching condition or in descending order of the numerical value indicated by the matching condition. Sort the acquired point name information in ascending order. Further, for example, when the spot name information is acquired using the attribute, the spot name information acquiring unit 146 sorts the acquired spot name information for each attribute.

  In addition, the spot name information acquisition unit 146 sorts the acquired spot name information based on two or more pieces of information, for example, after sorting for each area indicated by the area information, and further sorting for each area in order of distance. May be. The sorting method and procedure are not limited.

  In addition, the spot name information acquisition unit 146 calculates or acquires information calculated or acquired by each unit according to the reference information included in the acquisition reference designation instruction received by the reception unit 13. You may instruct. For example, when the reference information indicates that the location name information is acquired using the distance, the location name information acquisition unit 146 instructs the distance calculation unit 142 to calculate the distance. In addition, for example, when the reference information indicates that the location name information is acquired using the area information, the location name information acquisition unit 146 instructs the area acquisition unit 143 to acquire the area information. Further, for example, when the reference information indicates that the point name information is acquired using the matching condition, the point name information acquiring unit 146 instructs the matching condition acquiring unit 144 to acquire the matching condition. For example, when the reference information indicates that the location name information is acquired using the attribute, the location name information acquisition unit 146 instructs the attribute acquisition unit 145 to acquire the attribute.

  Moreover, when acquiring point name information using distance, the point name information acquisition means 146 is the point name information containing the character which the said distance satisfy | filled the predetermined condition and the reception part 13 received the input. Any method or procedure may be used as long as it can be acquired from the point information storage unit 11.

  Moreover, when acquiring point name information using area information, the point name information acquisition means 146 stores the point name information corresponding to the area and including characters received by the receiving unit 13 as point information. What is necessary is just to be able to acquire from the part 11, and the method, procedure, etc. do not ask | require.

  Moreover, when acquiring point name information using a matching condition, the point name information acquisition means 146 respond | corresponds to the positional information which the positional information acquisition part 12 acquired, and the said matching condition satisfy | fills predetermined conditions. The point name information only needs to be acquired from the point information storage unit 11, and its method and procedure are not limited.

  Moreover, when acquiring point name information using an attribute, the point name information acquisition means 146 contains the character | symbol corresponding to the positional information which the positional information acquisition part 12 acquired, and the reception part 13 received the input, And the point name information which the said attribute satisfy | fills the conditions determined beforehand should just be acquired from the point information storage part 11, and the method, a procedure, etc. are not ask | required.

  The point name information acquisition unit 146 can be usually realized by an MPU, a memory, or the like. The processing procedure of the spot name information acquisition unit 146 is usually realized by software, and the software is recorded in a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

In addition, the point name information acquisition part 14 may acquire point name information using 2 or more information among the information which the above-mentioned each means calculated or acquired. For example, the spot name information acquisition part 14 may acquire spot name information in the following procedures.
(1) The area acquisition unit 143 acquires area information corresponding to the position information acquired by the position information acquisition unit 12 from the area management information storage unit 141.
(2) The spot name information acquisition unit 146 acquires spot information corresponding to the area information acquired in (1) from the spot information storage unit 11.
(3) The distance calculation unit 142 calculates the distance between the position indicated by the point position information included in each piece of point information acquired in (2) and the position indicated by the position information acquired by the position information acquisition unit 12.
(4) The spot name information acquisition means 146 acquires the spot name information included in the spot information that satisfies the condition that the distance acquired in (3) is determined in advance among the spot information acquired in (2).

  The acquisition procedure is merely an example, and it goes without saying that various changes can be made to the information used by the spot name information acquisition unit 14.

  The output unit 15 outputs the spot name information acquired by the spot name information acquisition unit 14 as an input candidate. The input candidate is usually a character input candidate accepted by the accepting unit 13. The input candidate may be, for example, a character input candidate when searching for a nearby point or searching for a destination.

  Output is a concept that includes display on a display, projection using a projector, transmission to an external device, storage in a recording medium, delivery of a processing result to another processing device or another program, and the like. is there. In addition, regarding transmission, accumulation, and delivery of processing results, an output target is finally presented to the user.

  The output unit 15 normally outputs the spot name information in a predetermined format on a predetermined area on the screen, but the format or style of output of the spot name information is not limited. Moreover, when the spot name information acquisition part 14 acquires spot information, the output part 15 outputs the spot name information which each said spot information has as an input candidate.

  The output unit 15 may output the spot name information in response to the output order designation instruction received by the receiving unit 13. Specifically, the output unit 15 outputs spot name information according to the order information included in the output order designation instruction.

  For example, when the order information indicates that the spot name information is output based on the distance, the output unit 15 outputs the spot name information based on the distance calculated by the distance calculation unit 142. “Based on distance” means the order in which the distance is close or the order in which the distance is long.

  For example, when the order information indicates that the spot name information is output based on the area, the output unit 15 outputs the spot name information based on the area indicated by the area information acquired by the area acquiring unit 143. “Based on the region” means each region or the alphabetical order of the region.

  Further, for example, when the order information indicates that the point name information is output based on the matching condition with the character received by the receiving unit 13, the output unit 15 sets the matching condition acquired by the matching condition acquisition unit 144. Based on this, the point name information is output. “Based on the degree of matching” means the order in which the degree of matching is high, the order in which the degree of matching is low, the order in which the matching position is small, the order in which the matching position is large, and the type of matching.

  For example, when the order information indicates that the spot name information is output based on the attribute of the spot name information, the output unit 15 outputs the spot name information based on the attribute acquired by the attribute acquisition unit 145. “Based on attribute” means the order in which the number of characters is large, the order in which the number of characters is small, the order in which the number of selections is large, the order in which the number of selections is small, the order in which the percentage of kanji is included, .

  The output unit 15 may or may not include an output device such as a display or a speaker. The output unit 15 can be realized by driver software for an output device or driver software for an output device and an output device.

  Next, the operation of the point name output device 1 will be described. Note that the i-th information in the predetermined information is described as “information [i]”. FIG. 2 is a flowchart showing the overall operation of the point name output device 1.
