  The refinement condition storage unit 102 stores one or more refinement conditions. The narrowing-down condition is a condition for acquiring one or more pieces of point information from one or more pieces of point information. Further, the narrowing-down condition is usually a condition related to a point.

  The narrowing-down condition is, for example, to match the user's fortune. The user's fortune includes, for example, a direction (direction) in which the fortune rises, a lucky color, a lucky item, and the like. Further, the fortune of the user is usually indicated by fortune information. In addition, the fortune information is usually stored in a fortune information storage unit 103 described later. For example, the narrowing-down condition that means matching with the user's fortune regarding the direction is, for example, “fortune rising direction”, “fortune (direction)”, or the like. Further, for example, the narrowing-down condition that means matching with the user's fortune relating to the color is, for example, “lucky color”, “fortune (color)”, or the like.

  Further, the narrowing-down condition is to be selected by a predetermined selection method, for example. The predetermined selection method is, for example, random numbers, Amidokuji, roulette, or the like. The selection method is usually indicated by selection information. In addition, the selection information is normally stored in a selection information storage unit 104 described later.

The selection information storage unit 104 may store one or more selection information.

  The current position information acquisition unit 105 acquires current position information that is position information indicating the current position. The current position information acquisition unit 105 normally acquires current position information periodically. The current position information acquisition unit 105 acquires current position information from a satellite navigation system (such as a GPS receiver) or a device that receives position information from a base station for mobile communication. In this case, the current position information acquisition unit 105 may have these devices or may be realized by these devices. The processing procedure of the current position information acquisition unit 105 is usually realized by software, and the software is recorded on a recording medium such as a ROM.

  The receiving unit 106 receives a point search instruction and a point selection instruction. Acceptance refers to accepting information input from an input device such as a touch panel or a keyboard, receiving information transmitted via a wired or wireless communication line, and reading from a recording medium such as an optical disk, magnetic disk, or semiconductor memory. It is a concept that includes the reception of information that has been made.

  The point search instruction is an instruction to search for a point. Further, the point search instruction may be an instruction for starting a point search. The point search instruction has a time condition that is a condition related to time. The point selection instruction is an instruction to select a point. Further, the point selection instruction may be an instruction for starting a route search to the selected point and route guidance to the point.

  Here, the time condition is a condition having time information. Time information is information indicating time. Further, the time condition included in the point search instruction usually has one piece of time information. Moreover, the said time condition may have two time information, for example. The time width is indicated by the two pieces of time information.

  The time indicated by the time information is, for example, the time required to make a round trip between the departure place and the destination (hereinafter referred to as a round trip time as appropriate), the time required to make a round trip between the departure place and the destination, and the stay at the destination. These are the time obtained by adding the time (hereinafter referred to as round trip time, as appropriate), the time from the departure point to the destination (hereinafter referred to as appropriate, one-way time), and the like.

  Therefore, when one time information is included, the time condition is, for example, that the round trip time is less than or equal to the time indicated by the time information, or that the round trip time is less than or equal to the time indicated by the time information. is there. In addition, when two pieces of time information are included, the time condition is, for example, that the round trip time is within a time range indicated by the two time information, or that the round trip time is the time indicated by the two time information. It is more than the lower limit and less than the upper limit of the width.

  In addition, the reception unit 106 may receive, for example, a power-on instruction or a power-off instruction. When the receiving unit 106 receives these instructions, the navigation device 1 normally performs processing according to the received instructions.

  Further, the input means such as information and instructions in the receiving unit 106 may be anything such as a menu screen or a keyboard. The receiving unit 106 can be realized by control software for a menu screen, a device driver for input means such as a keyboard, and the like.

  The time condition creating unit 107 creates a time condition related to the time width using the time information and the time width information. The time information is usually time information included in a time condition included in the point search instruction. The time width information is information indicating the time width, and is normally held by the time condition creating unit 107. Also, the time condition created by the time condition creating unit 107 is usually a time condition having two pieces of time information.

  Here, the time width information is usually time information having a sign of negative, positive / negative, or positive. The time width information is, for example, “−1 hour”, “± 30 minutes”, “+1 hour”, and the like.

  For example, the time condition creation unit 107 first acquires time information included in the time condition from the time condition included in the point search instruction received by the reception unit 106. Then, the time condition creating unit 107 adds two pieces of time information by adding the held time width information to the acquired time information. Then, the time condition creating unit 107 creates a time condition having the acquired two pieces of time information.

  For example, when the time width information has only a negative sign, the time condition creating unit 107 adds the negative time width information to the time information acquired from the time condition, and adds the time information before the addition and the time information after the addition. Two pieces of time information are acquired. For example, it is assumed that the time width information is “−1 hour” and the time information is “2 hours”. In such a case, the time condition creating unit 107 adds the positive time width information “−1 hour” to the time information “2 hours”, and adds the time information “2 hours” before the addition. Time information “1 hour” is acquired.

  Further, for example, when the time width information has a positive / negative sign, the time condition creating unit 107 adds the positive and negative time width information to the time information acquired from the time condition, and adds the two after the addition. Get time information. For example, it is assumed that the time width information is “± 30 minutes” and the time information is “3 hours”. In such a case, the time condition creating unit 107 adds each of the positive time width information “+30 minutes” and the negative time width information “−30 minutes” to the time information “3 hours”. Then, two pieces of time information “3 hours 30 minutes” and “2 hours 30 minutes” are acquired.

  Note that the two time information acquisition methods and procedures when the time width information has only a positive sign are the two time information acquisition methods and procedures when the time width information has only a negative sign. Since it is the same as that, the description is omitted.

  In addition, the time condition creating unit 107 uses the two time information acquired as described above (respectively, time information 1 and time information 2), and the time condition “$ time information 1 $ or more and $ time information 2”. $ "Or less" or "$ time information 1 $ or more and $ hour information 2 $" or less. “$ Time information 1 $” and “$ Time information 2 $” are variables for substituting time information. Of course, the smaller one of the two pieces of acquired time information is time information 1, and the larger one is time information 2. Moreover, the time condition to create does not ask | require a format, a content, etc. if said meaning can be shown.

  For example, it is assumed that the acquired two pieces of time information are “2 hours 30 minutes” and “3 hours 30 minutes”. In such a case, for example, the time condition creating unit 107 creates a time condition “2 hours 30 minutes ≦ time ≦ 3 hours 30 minutes” having the two pieces of time information. In this case, for example, the time condition creating unit 107 may create the time condition “2 hours 30 minutes ≦ time <3 hours 30 minutes”.

The time calculation unit 108 calculates the time between two points. The the "time between two points" is a time required for moving between two points. Further, the “two points” may be “two positions”. In addition, any one of the “two points” may be a position. Further, the “moving” may be “running”. Further, the “calculating time” usually means obtaining time information indicating time. The “time required for movement” is usually one of a round trip time, a round trip stay time, and a one way time.

  The time calculation unit 108 normally calculates the time between the current position and one or more points on the map. The current position is the current position indicated by the current position information acquired by the current position information acquisition unit 105. The one or more points are points indicated by one or more pieces of point information included in the map information stored in the map information storage unit 101. Further, the one or more pieces of spot information may be, for example, all spot information included in the map information, or may be all spot information included in the map information output by the output unit 111 described later. Then, it may be one or more pieces of point information designated by the point information acquisition unit 110 described later, or may be one or more pieces of point information that match the above-described narrowing conditions. Further, the time calculation unit 108 normally calculates the time between the point indicated by the point information and the current position for each of the one or more pieces of point information.

  For example, for one piece of point information, the time calculation unit 108 normally searches for a route from the current position to the point indicated by the one piece of point information. The route is, for example, a round-trip route or a one-way route. When searching for a round-trip route, for example, the time calculation unit 108 searches for a route in which the current position is the departure point and the destination, and the point indicated by the one point information is a transit point. Further, when searching for a round-trip route, the time calculation unit 108 may search for only a one-way route, for example. When searching for a one-way route, the time calculation unit 108 normally searches for a route in which the current position is the departure point and the point indicated by the one point information is the destination. Then, the time calculation unit 108 acquires route information indicating the searched route.

  The route information usually has one or more sections. Each section is usually indicated by one road information. That is, the route information is usually information having one or more road information. Therefore, the time calculation unit 108 uses one or more distance information included in the route information and one or more speed limit information to calculate a time required for moving the route indicated by the route information.

  The speed limit information used when calculating the time may be current speed information indicating the current speed, for example. In this case, the current speed information is usually acquired by a speed information acquisition unit (not shown). The speed information acquisition unit usually acquires speed information from a device such as a speed sensor or a speedometer. In this case, the speed information acquisition unit may have, for example, these devices or may be realized by these devices. The processing procedure of the speed information acquisition unit is usually realized by software, and the software is recorded on a recording medium such as a ROM.

  In addition, the search for the route and the acquisition of route information are usually performed by the route search unit 109 described later. At this time, the time calculation unit 108 normally instructs the route search unit 109 to search for a route from the current position to the point indicated by the one point information.

  In addition, the time calculation unit 108 may calculate the time required to move the linear distance between two points, for example. In this case, for one piece of point information, the time calculation unit 108 first calculates the distance from the current position to the point indicated by the one piece of point information. The “calculating the distance” usually means obtaining distance information indicating the distance. Then, the time calculation unit 108 calculates the time required to move the distance using the distance information and the current speed information.

  Note that a method and a procedure for calculating time using distance information and speed information are well-known, and a description thereof will be omitted.

  In addition, the time calculation unit 108 normally calculates time according to the type of time information included in the time condition. The type of the time information is, for example, one of a round trip time, a round trip stay time, and a one way time.

  When calculating the round trip time, for example, the time calculation unit 108 first acquires route information indicating a round trip route. Then, the time calculation unit 108 calculates the round trip time using the route information indicating the round trip route. When calculating the round trip time, for example, the time calculation unit 108 first acquires route information indicating a one-way route. Then, the time calculation unit 108 calculates the one-way time using the route information indicating the one-way route. Then, the time calculation unit 108 doubles the one-way time to calculate the round trip time.

  Further, when calculating the round trip time, the time calculation unit 108 first calculates the round trip time as described above, for example. Then, the time calculation unit 108 adds the stay time at the destination to the round trip time. The stay time is the stay time indicated by the stay time information included in the map information.

  When calculating the one-way time, the time calculation unit 108 calculates the one-way time as described above, for example.

  The route search unit 109 normally searches for a route between two designated points. Then, route information indicating the route is acquired. The “two points” may be “two positions”. In addition, any one of the “two points” may be a position. Further, the route search unit 109 normally searches for a route from a point designated as a departure point to a point designated as a destination. Further, the information indicating the point is point information, and the information indicating the position is position information.

  Specifically, the route search unit 109 normally stores point information indicating the departure point (hereinafter referred to as departure point information as appropriate) and point information indicating the destination (hereinafter referred to as destination information as appropriate) as map information. This is applied to the map information stored in the unit 101. Further, for example, when a waypoint is also designated, the route search unit 109 also applies point information indicating the waypoint (hereinafter, route point information as appropriate) to the map information.

  “Apply departure point information to map information” means that a point on the map indicated by the departure point information is set as a departure point. “Applying destination information to map information” means that a point on the map indicated by the destination information is set as the destination. Further, “apply route point information to map information” means that a point on the map indicated by the route point information is set as a route point.

  Then, the route search unit 109 searches for a route from the departure point indicated by the departure point information applied to the map information to the destination indicated by the destination information applied to the map information. In addition, for example, when the transit point information is also applied to the map information, the route search unit 109 searches for a route from the departure point to the destination via the transit point indicated by the transit point information. Then, the route searching unit 109 acquires route information indicating the above route. The route information usually indicates a route from the departure place to the destination. Further, the route information may indicate, for example, a route from a departure point to a destination via a waypoint.

  Note that the route search usually uses a solution (algorithm) of the shortest route problem. “Solving the shortest path problem” is, for example, the Dijkstra method or the A * algorithm. Since these solutions are well-known, detailed description is abbreviate | omitted.

  For example, when there is an instruction from the time calculation unit 108, the route search unit 109 is usually one of the current position information and one or more point information included in the map information, and the point information specified by the time calculation unit 108 And apply to map information. Then, the route search unit 109 searches for a route from the position indicated by the current position information to the point indicated by the point information.

  For example, when the reception unit 106 receives a point selection instruction, the route search unit 109 normally applies the current position information and the point information selected by the point selection instruction to the map information. Then, the route search unit 109 searches for a route from the position indicated by the current position information to the point indicated by the point information. At this time, when the route information is associated with the selected point information, the route search unit 109 does not have to acquire the route information.

  The spot information acquisition unit 110 usually acquires one or more spot information that matches the time condition from the map information storage unit 101. Further, the point information acquisition unit 110 may acquire, from the map information storage unit 101, for example, one or more pieces of point information that match a time condition and a narrowing condition. The time condition is a time condition included in the point search instruction received by the receiving unit 106 or a time condition created by the time condition creating unit 107. The narrowing condition is a narrowing condition stored in the narrowing condition storage unit 102.

  The “point information that matches the time condition” is point information that matches the time condition calculated by the time calculation unit 108 described above. “Point information that matches the narrowing conditions” means point information that matches the information specified by the narrowing conditions, or point information selected by the information specified by the narrowing conditions, or narrowing It is point information that meets the conditions. “Information specified by the narrow-down condition” is, for example, fortune information, selection information, and the like.

  Specifically, the point information acquisition unit 110 normally determines whether or not the time information acquired by the time calculation unit 108 for one piece of point information matches the time condition. When the time information matches the time condition, the spot information acquisition unit 110 acquires the spot information.

  Further, the spot information acquisition unit 110 determines whether or not information related to the spot information, information included in the spot information, and the like match the information specified by the narrowing-down condition for one spot information. At this time, for example, the spot information acquisition unit 110 may determine whether or not the spot information matches the spot information selected by the information specified by the narrowing-down condition. At this time, for example, the spot information acquisition unit 110 may determine whether the information included in the spot information matches a narrowing condition. And when it corresponds, the spot information acquisition part 110 judges that the said spot information corresponds to narrowing-down conditions, and acquires the said spot information.

  In addition, when acquiring one or more pieces of point information that matches the time condition and the narrowing-down condition, the order of application of these two conditions is not limited. That is, the spot information acquisition unit 110 acquires, for example, one or more spot information that matches the time condition from the map information storage unit 101, and from the one or more spot information, the one or more spots that match the narrowing condition Information may be acquired. In addition, the spot information acquisition unit 110 acquires, for example, one or more spot information that matches the narrowing condition from the map information storage unit 101, and from the one or more spot information, one or more spots that match the time condition Information may be acquired.

  For example, it is assumed that the time condition is “3 hours ≦ round trip time ≦ 4 hours”. The time condition means that the round trip time is 3 hours or more and 4 hours or less. In this case, the time calculation unit 108 acquires time information indicating the round trip time from the current position for one piece of point information. For example, it is assumed that the time information is “3 hours 30 minutes”. In such a case, the spot information acquisition unit 110 determines that the time information matches the time condition.

  Further, for example, it is assumed that the time condition is “5 hours 30 minutes ≦ round-trip stay time <6 hours 30 minutes”. The time condition means that the round trip stay time is 5 hours 30 minutes or more and less than 6 hours 30 minutes. In this case, the time calculation unit 108 acquires time information indicating the round-trip stay time from the current position for one piece of point information. For example, it is assumed that the time information is “6 hours and 15 minutes”. In such a case, the spot information acquisition unit 110 determines that the time information matches the time condition.

  Further, for example, it is assumed that the time condition is “within 3 hours one way”. In this case, the time calculation unit 108 acquires time information indicating one-way time from the current position for one piece of point information. Further, for example, it is assumed that the time information is “2 hours 30 minutes”. In such a case, the spot information acquisition unit 110 determines that the time information matches the time condition.

  Further, for example, it is assumed that the narrowing-down condition is “a fortune rising direction”. The narrowing-down condition means that the user's fortune relating to the direction is met. In this case, the spot information acquisition unit 110 calculates the azimuth from the current position for one spot information. “Calculating the azimuth” means acquiring azimuth information indicating the azimuth. Moreover, since the method, procedure, etc. which calculate the azimuth | direction of the other point from one point are well-known about two points, description is abbreviate | omitted. Also, in this case, the fortune information storage unit 103 normally stores fortune information indicating the user's fortune regarding the direction. And the point information acquisition part 110 judges whether the said azimuth | direction information corresponds to the said fortune information.

  For example, in the above, it is assumed that the direction information is “north” and the fortune information is “north”. In this case, the azimuth information that is information related to the point information matches the fortune information that is information specified by the narrowing-down condition. Therefore, in such a case, the spot information acquisition unit 110 determines that the spot information matches the narrowing-down condition.

  For example, assume that the narrowing-down condition is “lucky color”. The narrowing-down condition means that it matches the user's fortune regarding color. In this case, the spot information acquisition part 110 acquires the color information which the said spot information has about one spot information. In this case, the fortune information storage unit 103 normally stores fortune information indicating the user's fortune regarding colors. Then, the spot information acquisition unit 110 determines whether or not the color information matches the fortune information.

  For example, in the above, it is assumed that the color information is “red” and the fortune information is “red”. In this case, the color information that is information included in the point information matches the fortune information that is information specified by the narrowing-down condition. Therefore, in such a case, the spot information acquisition unit 110 determines that the spot information matches the narrowing-down condition.

  For example, assume that the narrowing-down condition is “random number”. The narrowing-down condition means that the selection is made by a random number. In this case, the selection information storage unit 104 normally stores selection information such as a function for returning a random number and a program for generating a random number. And the spot information acquisition part 110 acquires the spot information selected by the said selection information using the said selection information.

  For example, in the above, it is assumed that the acquired random number is “2”. In this case, the second point information is selected by the random number. Therefore, in such a case, the spot information acquisition unit 110 determines that the second spot information matches the narrowing-down condition, and acquires the second spot information. At this time, the order in which the point information is sorted does not matter. The order is, for example, an ascending or descending order of identifiers for identifying point information, an ascending or descending order of name information indicating the name of the point, and the like.

  Further, for example, it is assumed that the narrow-down condition is “Amidakuji”. This narrowing-down condition means that it is selected by Amida lottery. In this case, the selection information storage unit 104 normally stores selection information such as a function for realizing an Amida lottery and a program for realizing an Amida lottery. And the spot information acquisition part 110 acquires the spot information selected by the said selection information using the said selection information.

  For example, in the above, it is assumed that the second point information is selected by the Amida lottery. In such a case, the spot information acquisition unit 110 determines that the second spot information matches the narrowing condition, and acquires the second spot information. At this time, the order in which the point information is sorted does not matter. The order is, for example, an ascending or descending order of identifiers for identifying point information, an ascending or descending order of name information indicating the name of the point, and the like.

  Further, for example, it is assumed that the narrowing-down condition is “type = landmark”. The narrowing-down condition means that the type of the spot is “landmark”. In this case, the spot information acquisition unit 110 determines that one or more spot information having the type information “landmark” matches the narrowing condition.

  Further, for example, when two or more narrowing conditions are stored in the narrowing condition storage unit 102, the point information acquisition unit 110, for example, according to the priority order information associated with the narrowing condition, 1 The above point information is acquired.

  (1) When priority information is not associated: In this case, the spot information acquisition unit 110 acquires one or more spot information that matches all of the time condition and the two or more filtering conditions. In this case, the order of application of the time condition and two or more narrowing conditions is not limited.

  (2) When priority information is associated: In this case, the spot information acquisition unit 110 acquires one or more pieces of spot information, for example, by any of the following procedures.

(Procedure 1)
(1-1) Two or more sets of point information that match either the time condition or the two or more narrowing conditions are acquired for each of the two or more narrowing conditions.
(1-2) The priority information used when the set of the point information is acquired is associated with the set of two or more pieces of the acquired point information.

(Procedure 2)
(2-1) One or more point information that matches all of the time condition and the two or more narrowing conditions is acquired. At this time, the narrow-down conditions are applied in the order of the priorities indicated by the priority information associated with the narrow-down conditions.

  In the case of (2) above, the point information acquisition unit 110 uses only the narrowing-down condition associated with the priority information that matches a predetermined condition (hereinafter referred to as priority condition as appropriate), You may acquire one or more point information. The priority condition is a condition related to priority information. The priority condition includes, for example, that the order indicated by the priority order information is equal to or higher than a predetermined order, or that the order is higher than a predetermined order and equal to or lower than a predetermined order.

  In addition, the spot information acquisition unit 110 may associate priority information with one or more acquired pieces of spot information, for example. In this case, the spot information acquisition unit 110 normally associates priority order information according to the narrowing-down conditions. Specifically, the spot information acquisition unit 110 associates priority order information according to the order information included in the narrow-down condition. At this time, the spot information acquisition unit 110 normally associates the priority order information so as to indicate the order indicated by the order information.

  For example, it is assumed that the order information is “time ascending order”. In this case, for example, the spot information acquisition unit 110 associates the priority order information with the acquired one or more pieces of spot information so as to indicate the ascending order of the time calculated by the time calculation unit 108. Further, for example, it is assumed that the order information is “descending order of stay time”. In this case, for example, the spot information acquisition unit 110 associates priority order information with one or more acquired spot information so as to indicate the ascending order of the stay times indicated by the stay time information corresponding to the spot information. Further, for example, it is assumed that the order information is “distance descending order”. In this case, for example, the spot information acquisition unit 110 associates priority order information with the acquired one or more pieces of spot information so as to indicate the descending order of the distances calculated when the time calculation unit 108 calculates the time. For example, it is assumed that the order information is “type ascending order”. In this case, for example, the spot information acquisition unit 110 associates priority information with one or more acquired spot information so as to indicate the ascending order of the type information included in the spot information.

  The output unit 111 outputs one or more point information and route information. The one or more pieces of spot information are spot information acquired by the spot information acquisition unit 110. The route information is route information acquired by the route search unit 109. Also, output refers to display on a display, projection using a projector, printing with a printer, sound output, transmission to an external device, accumulation in a recording medium, processing to other processing devices or other programs, etc. It is a concept that includes delivery of results. In addition, regarding transmission, accumulation, and delivery of processing results, an output target is finally presented to the user.

  The output unit 111 normally outputs the one or more pieces of spot information when the spot information acquisition unit 110 acquires the spot information. At this time, if priority information is associated with the one or more pieces of spot information, the output unit 111 outputs the one or more pieces of spot information in the order of priority indicated by the priority information. In addition, the format and format at the time of the output are not limited.

  The output unit 111 normally outputs the route information when the route search unit 109 acquires the route information. At this time, the output unit 111 normally outputs route information together with the map information stored in the map information storage unit 101.

  In addition, for example, when one of the output one or more pieces of spot information is selected according to the spot selection instruction received by the receiving unit 106, and the route information is associated with the selected spot information. The output unit 111 outputs the route information.

  The output unit 111 may be considered to include an output device such as a display or a speaker, or may not be included. The output unit 111 can be implemented by output device driver software, or output device driver software and an output device.

  The map information storage unit 101, the narrow-down condition storage unit 102, the fortune information storage unit 103, and the selection information storage unit 104 are preferably non-volatile recording media, but can also be realized by volatile recording media. Moreover, the process in which predetermined information is memorize | stored in the map information storage part 101 etc. does not ask | require. For example, the predetermined information may be stored in the map information storage unit 101 or the like via a recording medium, a communication line, an input device, or the like.

Then, the current position information acquisition unit 105 starts acquiring current position information. Further, the car navigation system acquires map information corresponding to the current position indicated by the current position information from the map information storage unit 101. Then, the output unit 111 outputs the map information.

  Next, it is assumed that the driver operates the car navigation system and inputs time information “2:00” indicating a one-way time. The time information means “2 hours”. Then, the reception unit 106 receives a point search instruction having a time condition “one-way time ≦ 2: 00”.

  Next, the time condition creating unit 107 creates a time condition related to the time width using the time condition included in the point search instruction and the time width information held by itself. Here, it is assumed that the time condition creating unit 107 holds time width information “± 0: 00”. The time width information means that the time width is “0”. Then, the time condition creating unit 107 acquires the time condition “one-way time ≦ 2: 00”. As described above, when the time width information indicating that the time width is “0” is held, the time condition creating unit 107 acquires the time condition included in the point search instruction as it is.

  Next, the time calculation unit 108 calculates the one-way time from the current position for each piece of point information in FIG. At this time, the time calculation unit 108 instructs the route search unit 109 to search for a route from the current position for each piece of point information in FIG. Then, the route search unit 109 searches for the route from the current position for each piece of point information in FIG. 5, and acquires route information indicating the route.

Then, the spot information acquisition unit 110 acquires the three spot information.

  Also, for example, it is assumed that the driver operates the car navigation system and inputs time information “6:00” indicating the round trip time. The time information means “6 hours”. Then, the reception unit 106 receives a point search instruction having the time condition “round trip time ≦ 6: 00”.

  Next, it is assumed that the time condition creating unit 107 holds the time width information “± 1: 0”. The time width information means that the time width is “± 1 hour”. Then, the time condition creation unit 107 adds the time width information to the time information included in the time condition, and acquires a new time condition “5: 00 ≦ round trip time ≦ 7: 00”.

  Next, the time calculation unit 108 calculates the round trip time for each piece of point information in FIG. 5 in the same manner as described above. Specifically, the time calculation unit 108 acquires time information indicating the one-way time from the route information acquired by the route search unit 109, and doubles the time information, as described above. And the time calculation part 108 adds the stay time information which the point information of FIG. 5 has to the time information which shows the said round trip time. As a result, the time calculation unit 108, for each piece of point information in FIG. 5, in order from “ID = 011”, time information “8:40”, “7:30”, “6:50” indicating the round trip time. “8:30”, “2:40”, “3:00”, “4:00”, “5:30”, “6:00”, “8:20”, “4:00”, “4” : 40 ”.

  Next, in the same manner as described above, the spot information acquisition unit 110 determines which time information out of the 12 pieces of time information matches the time condition “5: 00 ≦ round trip time ≦ 7: 00”. Judging. Then, the point information acquisition unit 110 performs time information “6:50” and “5:30” corresponding to the three pieces of point information “ID = 013”, “ID = 018”, and “ID = 019” in FIG. , “6:00” is determined to match the time condition “5: 00 ≦ round trip time ≦ 7: 00”. Then, the spot information acquisition unit 110 acquires the three spot information.
