The parking lot guidance method of Patent Document 1 is intended to prevent an increase in local traffic volume, alleviate traffic congestion, and distribute and average vehicles in each parking lot to increase the operating rate of the parking lot. And the parking lot guidance method analyzes the destinations of vehicles traveling in the traffic network, creates recommendations for parking lots that each vehicle should use, and provides parking recommendations for each vehicle In this case, the traffic situation after a predetermined time is predicted, the evaluation value of the parking lot recommendation plan is obtained by a predetermined objective function, and the parking lot recommendation plan having the maximum or minimum evaluation value is searched.

Japanese Patent Laid-Open No. 9-212557

However, in the case of a large parking lot having a plurality of entrance gates, the technique of Patent Document 1 becomes the same destination regardless of which entrance gate is used for entry. In addition, the evaluation value of the parking lot recommendation plan is obtained by the objective function, and the parking lot recommendation plan that maximizes or minimizes the evaluation value is searched through the repeated processing. It is difficult to guide.

An object of the present invention is to provide a technology that can be applied to a large-scale parking lot having a plurality of entrance gates, can smoothly guide a large number of vehicles to the entrance gate, and does not require many repeated processes. .

The parking lot guidance device of the present invention guides a vehicle equipped with a user terminal having GPS means, navigation means, and wireless communication means to a parking lot having a plurality of entrance gates. The first parking lot guidance device of the present invention includes a recording unit, an arrival time prediction unit, a time group determination unit, a gate determination unit, a traffic jam prediction unit, and a guidance information transmission unit. The recording unit records / updates information that identifies the user terminal, road information in a predetermined range around the parking lot (including information on at least traffic closures and traffic jams), and vacant information that indicates the vacant parking space for each entrance gate And record the traffic congestion criteria for a given node. The arrival time prediction unit predicts the estimated arrival time when the vehicle arrives at a predetermined position using the road information when the user terminal satisfies a predetermined arrival prediction condition. The time group determination unit determines a time group to which the user terminal belongs based on the estimated arrival time. The gate determination unit determines, for each time group, an entrance gate into which a vehicle on which a user terminal belonging to the time group is mounted is used by using empty information. The traffic jam prediction unit includes a route prediction unit, a traffic jam node specifying unit, and a traffic jam prediction information creating unit, and generates traffic jam prediction information for each user terminal. The route prediction means obtains a route to reach the determined entrance gates of all user terminals using road information for each time group. The traffic jam node specifying means obtains a traffic jam node as a traffic jam node by using the traffic jam criteria of the route and the node. For each user terminal, the traffic jam prediction information creation means decides whether or not to bypass the traffic jam node based on a predetermined detour criterion. In this case, information for identifying a node where a traffic jam occurs is not included in the traffic jam prediction information. The guidance information transmission unit transmits information on entrance gates and traffic jam prediction information to the user terminal as guidance information.

The second parking lot guidance device of the present invention includes a recording unit, a time group determination unit, a gate determination unit, a traffic jam prediction unit, and a guidance information transmission unit. In the second parking lot guidance apparatus of the present invention, there is no arrival time prediction unit, and the time group determination unit determines the time group to which the user terminal belongs based on when the user terminal falls within a predetermined range. . Other components are the same as those of the first parking lot guidance apparatus.

According to the parking lot guidance apparatus of the present invention, since the vehicle is guided in units of entrance gates, it can be applied to a parking lot having a plurality of entrance gates. In addition, the entrance gates are decided after grouping according to the estimated arrival time or when it falls within a predetermined range, and the occurrence of traffic jams is predicted by setting traffic jam standards for nodes around the parking lot. Do not need. Therefore, even a large number of vehicles can be guided to the entrance gate in real time.

Hereinafter, embodiments of the present invention will be described in detail. In addition, the same number is attached | subjected to the structure part which has the same function, and duplication description is abbreviate | omitted.

Figure 1 is an image of a large parking lot and the surrounding roads. The parking lot for dealing with large-scale events has a parking space for a large number of vehicles, such as 5000 to 10,000 cars, especially 10,000 cars for large events, and has a plurality of entrance gates. In the example of FIG. 1, the parking lot 600 includes four entrance gates 610-A to D, and the parking spaces of vehicles that have entered from each entrance gate are 620-A to D. In addition, between the parking spaces, the vehicle may be allowed to pass or the vehicle may not be allowed to pass, but the parking lot targeted by the present invention may be either. There is a road 700 around the parking lot 600 and nodes 701 to 706. In addition, although the node has shown the intersection in FIG. 1, you may also set as a node the place where the traffic volume which can pass in fixed time by traffic lights, road construction, etc. is restrict | limited than the surrounding road. Routes 711 to 715 show examples of routes where the vehicle enters the range where the parking lot guidance apparatus 100 of the present invention guides the route to the parking lot.

FIG. 2 is a diagram illustrating a functional configuration example of the parking lot guidance apparatus 100 according to the first embodiment. FIG. 3 is a diagram illustrating an example of a processing flow of the parking lot guidance apparatus 100 according to the first embodiment. The parking lot guidance device 100 is configured to connect a vehicle equipped with user terminals 300-1 to 300-N (where N is an integer of 1 or more) having GPS means 311, navigation means 312 and wireless communication means 313 to a plurality of entrance gates. Guide to the parking lot with The GPS means 311 is a means for measuring the current position by GPS (Global Positioning System). The navigation means 312 is a means for indicating a route to a destination and guiding a vehicle or the like. The user terminal is, for example, a smart in-vehicle information terminal. Assuming a parking lot where more than 5000 vehicles enter, the parking lot guidance device 100 exchanges information at the same time (for example, within a certain time of about one hour) as 1000 or more user terminals. There is a possibility. The parking lot guidance device 100 includes a recording unit 190, an arrival time prediction unit 110, a time group determination unit 120, a gate determination unit 130, a traffic jam prediction unit 140, a guidance information transmission unit 150, a communication unit 170, and a registration unit 180. The parking lot guidance device 100 is connected via a network 500 to a traffic control device 210 that manages road information of general roads, and an in-vehicle control device 220 that manages information such as an empty parking space in the parking lot. The user terminal 300-n periodically acquires position information by the GPS means 311 and transmits it to the parking lot guidance apparatus 100 by the wireless communication means 313. For example, it may be transmitted every minute. Further, the position information may include speed information (information on the traveling direction, average speed for the past five minutes, etc.).

The registration unit 180 stores in the recording unit 190 in advance information identifying the user terminal, road information in a predetermined range around the parking lot 600 (including at least traffic closure information and traffic jam information), and an empty parking space for each entrance gate. The available vacancy information, the information on the processing capacity of each entrance gate, and the congestion standard of a predetermined node are recorded. In addition, the registration unit 180 periodically updates the road information in a predetermined range around the parking lot and the vacant information indicating the vacant parking space for each entrance gate recorded in the recording unit 190. The road information may be acquired from the traffic control device 210, and the vacant information indicating the vacant parking space may be acquired from the on-site control device 220 and the user terminals 300-1 to 300-N.

“Information for identifying user terminals” is an identifier (number, e-mail address, etc.) for identifying each user terminal, and is registered when a user who wants to receive a parking guidance service applies (S301). , S180). For example, the registration unit 180 identifies the user terminal by accessing the parking lot guidance apparatus 100 (such as a parking lot guidance homepage) from the user terminal 300-n (where n is an integer between 1 and N). Information may be recorded in the recording unit 190. In the registration of the user terminal 300-n, the user information (for example, whether it is a general user, VIP, or disabled person) and the type of vehicle (for example, whether it is a normal car, a wagon car, a truck, etc.) ), Purpose of use (for example, general use, loading of luggage or materials, etc.) and information of friends (for example, information indicating that you are acting with other users) Identification information) may also be registered.

The predetermined range of the “road information of a predetermined range around the parking lot 600” is a predetermined range in which the parking lot guidance apparatus 100 guides the user terminal 300-n. In addition, the road information includes at least information on closed roads and information on traffic jams. In addition to this, information on traffic regulation due to construction or the like may be included. The “vacant information that indicates an empty parking space for each entrance gate” is information that indicates how many vehicles can be guided for each entrance gate. For example, the number PEX that has already entered the parking lot and the number PRE of the user terminals of vehicles that have already entered the parking lot but have not entered the parking lot are subtracted from the entire parking space PAL for each entrance gate. This is information for knowing the number (the number of empty PEMs). That is, PEM or a set of PAL, PEX, and PRE may be used. PAL and PEX can be acquired from the on-site controller 220. The PRE can be grasped from the position information sent from the user terminals 300-1 to 300-N.

“The information on the processing capacity of the entrance gate” is the number of vehicles that the entrance gate can pass per unit time (for example, 1 minute), or the time required for passing one vehicle. The predetermined node of the “predetermined traffic jam standard” may be all the intersections in the predetermined range around the parking lot 600, or only the intersection in the predetermined range around the parking lot 600 where traffic congestion is likely to occur. Alternatively, a place that is not an intersection but is likely to cause traffic congestion may be added to a predetermined node. The traffic jam criterion is, for example, the number of vehicles that can pass through a node smoothly in a unit time, and when it is predicted that vehicles exceeding that number will pass, it is determined that a traffic jam will occur.

The arrival time predicting unit 110 of the parking lot guidance apparatus 100, when the user terminal 300-n satisfies a predetermined arrival prediction condition (S101), arrives at a position where the vehicle arrives at a predetermined position using road information. Time is predicted (S110). The “predetermined arrival prediction condition” is a condition for determining that the user terminal 300-n has approached the range to be guided, and is, for example, slightly wider than the “predetermined range around the parking lot 600”. A range may be determined in advance, and a condition that the range is entered may be used. The “predetermined position” may be one place in the parking lot 600 or one place in the vicinity. For example, the entrance gate 610-A or the node 704 may be used. This is because the prediction of the arrival time is a pre-process for dividing the time group into the next process, and does not have to be the same as the entrance gate that actually receives the goods. Moreover, what is necessary is just to obtain | require estimated arrival time with the same technique as the prediction in general car navigation. For example, the arrival time prediction unit 110 may determine the time by dividing the distance of the shortest route by a predetermined average speed and add it to the current time. Further, the arrival time prediction unit 110 may obtain the estimated arrival time in consideration of traffic jam information from the traffic control device 210 and the like.

FIG. 4 is a diagram for illustrating the state of processing for the user terminal. When the user terminal 300-n satisfies the arrival prediction condition, the arrival time prediction unit 110 predicts the estimated arrival time and records it in the recording unit 190. Depending on the route from which the user terminal 300-n approaches the parking lot 600, it may be before or after. However, in many cases, the user terminal that satisfies the arrival prediction condition earlier has an earlier arrival time.

The time group determination unit 120 determines the time group to which the user terminal belongs based on the estimated arrival time (S120). In the example of FIG. 4, the user terminals are grouped into time groups in which the estimated arrival times are divided in units of 10 minutes. For example, a time group of 10:00 is a user terminal whose estimated arrival time is 10:00 to 10:09. As described above, the estimated arrival time is predicted from an early time although it is slightly around. Therefore, when the estimated arrival time that is later than the estimated final arrival time of a certain time group is predicted, the time group determination unit 120 may perform grouping of the time group. For example, when a time group of 10:00 is determined, when 10:15 is predicted as a scheduled arrival time for any user terminal, the time group determination unit 120 uses the data belonging to the time group of 10:00. The operator terminal may be confirmed. Since this grouping is not a process that requires high strictness, it is expected that the estimated arrival time will be 10:00 to 10:09 after the user terminals belonging to the 10:00 time group are confirmed. When there is a user terminal that has been set, the time group determination unit 120 may place the user terminal in the 10:10 time group.

For each time group, the gate determination unit 130 determines an entrance gate into which a vehicle equipped with a user terminal belonging to the time group enters using the vacant information and the processing capacity information (S130). For example, when the number of user terminals belonging to the time group is smaller than the total processing capacity of all the entrance gates, the gate determination unit 130 determines an entrance gate to preferentially enter the empty information. That is, the gate determination unit 130 assigns a user terminal to an entrance gate with a lot of free parking spaces within the processing capacity of the entrance gate. When the number of user terminals belonging to the time group is equal to or greater than the total processing capacity of all the entrance gates, the gate determination unit 130 determines the entrance gate to enter with priority on the processing capacity. For example, the gate determination unit 130 sets the entrance gates so that the ratio of the number of vehicles entering the vehicle to the processing capacity of each entrance gate (number of vehicles entering / processing capability) is averaged within the range of the empty parking space. decide.

In addition, when the determined entrance gate and the parking space are separated from each other, it is possible to smoothly go from entrance to parking by promptly guiding the parking space with the guide indicator light in the parking lot. The “guide light in the parking lot” is a device that is installed at the upper part of the intersection of the passages in the parking lot and displays the number, the number, etc. of the current empty space ahead. Since the user can check the empty space while driving the vehicle, parking can be performed smoothly. In addition, vehicle number recognition system, electronic toll collection system (ETC: Electronic Toll Collection System), and entrance / exit narrow-area communication system (DSRC: Dedicated Short Range Communication) can be passed without contact as a means to speed up admission processing. It is also possible to install a device (Reference 1: AMANO, “Parking related products”, [searched on September 24, 2013], Internet <URL: http://www.amano.co.jp/ Parking / products / parking_system / control.html>., (Reference 2: Mitsubishi Precision Corporation, “Parking Control System”, [searched on September 24, 2013], Internet <URL: http: // www .mpcnet.co.jp / product / parking / catalog / pdf / drivewaycontrol.pdf>.).

In addition, in the registration of the user terminal 300-n, the user information (for example, whether it is a general user, VIP or disabled person), and the type of vehicle (for example, a normal car, a wagon car, a truck, etc.) ), Purpose of use (for example, general use, loading of luggage or materials, etc.) and information of friends (for example, information indicating that you are acting with other users) When the information to be identified is also registered, the gate determination unit 130 may determine the entrance gate using the information. For example, the gate determination unit 130 always determines the entrance gate 610-A if it is a VIP, and always determines the entrance gate 610-D if it is a carry-in of luggage or materials. In addition, when there is information about friends, the gate determination unit 130 may determine the entrance gate such that the friends determine the same entrance gate. Furthermore, you may change how to decide an entrance gate according to a time slot | zone. For example, the gate determination unit 130 may not assign the entrance gate 610-C during a time period when the number of users is small. For example, it is determined as shown in the column of the entrance gate in FIG. However, in FIG. 4, the case where the entry gate 610-A is determined is indicated as “A”. Moreover, the gate determination part 130 may change how to determine so that the entrance gate of the parking space far from the place of an event may not be allocated when an event is performed around a parking lot. Furthermore, the gate determination unit 130 may determine an entrance gate and a parking position. In this case, the guidance information transmission unit 150, which will be described later, may transmit information on the parking position together with the entrance gate information and the traffic jam prediction information to the user terminal 300-n.

The traffic jam prediction unit 140 includes a route prediction unit 141, a traffic jam node specifying unit 142, and a traffic jam prediction information creating unit 143, and generates traffic jam prediction information for each user terminal (S140). More specifically, the route predicting means 141 obtains a route until reaching the determined entrance gates of all user terminals in the time group by using road information for each time group. The traffic jam node specifying unit 142 obtains a traffic jam node as a traffic jam node using the route of all user terminals in the time group and the traffic jam criteria of the nodes. For example, if the time group is grouped in units of 10 minutes and the congestion standard of the node 704 is 100 units in 10 minutes, the congestion node specifying unit 142 has 100 or more routes passing through the node 704. Node 704 is a traffic jam node.

The traffic jam prediction information creating means 143 determines for each user terminal whether or not to bypass the traffic jam node based on a predetermined bypass criteria, and if so, includes information identifying the traffic jam node in the traffic jam prediction information. If not, information specifying the node where the traffic jam occurs is not included in the traffic jam prediction information. Examples of the “detour criteria” include the following criteria, but are not limited thereto. In the first example, for each user terminal, it is confirmed whether there is a bypass route that reaches the determined entrance gate by bypassing the traffic jam node. When there is no detour route, the detour is not allowed. In the second example, the traffic jam node specifying unit 142 uses the traffic jam criteria of the node to obtain the number of bypass vehicles that must be detoured so as not to cause traffic jam. Then, for each user terminal, it is confirmed whether there is a bypass route that bypasses the traffic jam node and reaches the determined entrance gate, and the bypass vehicle is selected from the user terminals having the bypass route. A user terminal of a few or less is selected and bypassed, and other user terminals are not bypassed. For example, the congestion node specifying unit 142 bypasses all of the user terminals having a bypass route when the number of user terminals having a bypass route is equal to or less than the number of bypass vehicles, and bypasses when the number of user terminals having the bypass route is larger than the number of bypass vehicles. Select user terminals for the number of vehicles. The selection method may be random, or the first vehicle having a detour route to the number of detour vehicles may be detoured, and the rest may not be detoured. In the example of FIG. 4, the node 704 is a traffic jam node for the 10:00 time group and the 10:10 time group. In the example, it is determined that the user terminal entering from the entrance gates 610-A and B is determined not to be bypassed, and the user terminal entering from the entrance gates 610-C and D is determined to be bypassed.

The user terminal 300-n may further include a camera photographing unit and a vehicle speed determining unit. Then, for example, the user terminal 300-n continuously checks the vehicle speed with the vehicle speed determining means, determines that there is a traffic jam when the vehicle speed becomes 10 km / hour or less, and the current position acquired by the GPS means 311 You may transmit the traffic jam image | video acquired with the camera imaging | photography means to the parking lot guidance apparatus 100 as traffic jam information. The user terminal 300-n transmits the traffic jam information, so that the operator of the parking lot guidance apparatus 100 can more reliably confirm and grasp the current traffic jam. In addition, the operator of the parking lot guidance apparatus 100 can confirm the status of the node that has predicted the traffic jam, and can use it to correct the above-mentioned “traffic jam criteria” and “detour criteria”. Furthermore, the parking lot guidance apparatus 100 may transmit this traffic jam information to a user terminal where a detour route exists. Thereby, guidance can be performed more smoothly.

The guidance information transmission unit 150 transmits information on the entrance gate and traffic jam prediction information to the user terminal 300-n as guidance information via the communication unit 170 (S150). The information on the entrance gate is, for example, information on the name of the entrance gate (for example, “A gate”) and the latitude and longitude of the entrance gate. The traffic jam prediction information is, for example, information on the latitude and longitude of a traffic jam node. These examples are examples in which the positions of entrance gates and nodes are communicated by latitude and longitude, but it is not necessary to be limited to communication by latitude and longitude. For example, a code-position correspondence table may be shared in advance between the user terminal 300-n and the parking lot guidance apparatus 100, and only the codes may be communicated. In the case of the example of FIG. 4, for example, information on the latitude and longitude of the entrance gate 610-A and information on the latitude and longitude of the entrance gate 610-A are sent to the user terminal 300-1 as the entrance gate information. The information on the latitude and longitude of the node 704 is sent as information on the latitude and longitude of the “C gate” and the entrance gate 610-C as information on the entrance gate, and on the traffic jam prediction information. The guide information transmitting unit 150 may include not only the name of the entrance gate but also a guidance map around the entrance gate as the entrance gate information. When the gate determination unit 130 also determines the parking position, the guidance information transmission unit 150 may include the guidance map up to the position in the guidance information. In particular, in the case of an outdoor parking lot, it is often difficult from a cost standpoint to install a guide indicator light. By sending a guide map, parking can be performed smoothly while suppressing capital investment.

The user terminal 300-n receives the guidance information (S302). Then, the user terminal 300-n displays the name of the entrance gate on the display unit of the user terminal 300-n and informs the user from which entrance gate the entry is made. Further, the navigation means 312 sets the position of the entrance gate as the destination, determines the route in consideration of the traffic jam prediction information, and guides it (S312). The navigation means 312 may receive the road information from the traffic control device 210 and determine the route in consideration of the road information. The navigation means 312 may have the same function as a normal car navigation device, and is realized by registering the destination in latitude and longitude, and setting the traffic jam prediction information to be taken into consideration when selecting a route as well as road information. it can. In this way, by using the navigation means 312 of the user terminal 300-n, it is possible to guide in consideration of future traffic congestion that can be predicted in accordance with the determination of the entrance gate. In addition, since it is sufficient to leave the route search again when the user makes a mistake on the road, the load on the parking lot guidance apparatus 100 does not increase. Therefore, even when a large number of user terminals 300-1 to 300-N access at the same time, the burden on the processing of the parking lot guidance apparatus 100 can be reduced.

Since the parking lot guidance apparatus of the present invention guides the vehicle in units of entrance gates, the vehicle can be smoothly guided to a parking lot having a plurality of entrance gates. In addition, the parking lot guidance device according to the present invention determines the entrance gate after grouping according to the estimated arrival time, and sets the traffic jam criteria for the nodes around the parking lot to predict the occurrence of traffic jam. Does not require repeated processing on the terminal. Therefore, even when a large number of vehicles must be guided at the same time, the burden on the parking lot guidance device can be suppressed, so that all vehicles can be smoothly guided to the entrance gate.

[Modification 1]
The recording unit 190 of the parking lot guidance apparatus 100 may also record date information for the user terminals 300-1 to 300-N to use the parking lot 600. And you may have the following functions further.

The time group determination unit 120 confirms whether or not user terminals that exceed the total processing capacity of all entrance gates belong to one time group. When there is a time group to which user terminals with a total processing capacity or more belong, the time group determination unit 120 includes the user terminals 300-1 to 300-N in which information for identifying the user terminals is recorded in the recording unit 190. Among them, for a user terminal for which the day is the parking lot 600 and for which the estimated arrival time has not yet been predicted, information on the time of the time group to which the user terminals with the total processing capacity or more belong Together, information indicating that a traffic jam occurs at the entrance gate is transmitted via the communication unit 170. By sending the traffic jam prediction information in this way, the parking lot guidance apparatus 100 can have a user who has not yet left the house adjust the departure time.

Furthermore, the parking lot guidance apparatus 100 may also include a video acquisition unit 160. The video acquisition unit 160 acquires the video of the vehicle waiting for entry from the entrance gates 610-A to D, and determines whether or not there is a traffic jam. The determination as to whether a traffic jam has occurred may be determined from video, or from position information periodically sent from a user terminal near the entrance gate. If there is a traffic jam, the parking lot guidance device 100 uses the parking lot 600 for the day among the user terminals 300-1 to 300-N in which information for identifying the user terminal is recorded in the recording unit 190. For the user terminal that has not yet predicted the estimated arrival time, information indicating that there is a traffic jam at the entrance gate together with the acquired video is sent via the communication unit 170 Send. By sending traffic jam information in this way, the parking lot guidance apparatus 100 can have a user who has not yet left the house adjust the departure time.

[Modification 2]
In the parking lot guidance apparatus 100 according to the first embodiment, the arrival time prediction unit 110 predicts the estimated arrival time, and the time group determination unit 120 determines the time group to which the user terminal belongs based on the estimated arrival time. In this modification, the arrival time prediction unit 110 is not provided, and the time group determination unit 120 ′ determines a time group based on the location information of the user terminal 300-n. FIG. 5 shows a functional configuration example of the parking lot guidance apparatus 100 ′ according to the modified example, and FIG. 6 shows an example of a processing flow according to the modified example. The differences between the parking lot guidance apparatus 100 ′ of the present modification and the parking lot guidance apparatus 100 of the first embodiment are the absence of the arrival time prediction unit 110 and the grouping method of the time group determination unit 120 ′. Others are the same as in the first embodiment. Hereinafter, the processing of the time loop determination unit 120 ′, which is a difference, will be described.

The time loop determination unit 120 ′ checks whether the user terminal 300-n is within a predetermined range (S101 ′), and based on the time when the user terminal 300-n is within the predetermined range, the time to which the user terminal 300-n belongs A group is determined (S120 ′). For example, the time loop determination unit 120 ′ checks the positions of the user terminals 300-1 to 300 -N every 5 minutes, and sets the user terminals newly within a predetermined range as one time group. “Within a predetermined range” may be within 5 km of a parking lot, or a range may be defined for each route to the parking lot. The subsequent processing is the same as in the first embodiment.

The group of user terminals that newly entered within the predetermined range is not included in the range when the position was confirmed last time (for example, 5 minutes before), and is the group of user terminals that have entered this time. Therefore, since it is considered that the arrival time at the parking lot 600 is close, even if the time groups are divided by the method of the present modification, the same effect as in the first embodiment can be obtained.

[Program, recording medium]
The various processes described above are not only executed in time series according to the description, but may also be executed in parallel or individually as required by the processing capability of the apparatus that executes the processes. Needless to say, other modifications are possible without departing from the spirit of the present invention.

In addition, when the above configuration is realized by a computer, the processing contents of the functions that each device should have are described by a program. The processing functions are realized on the computer by executing the program on the computer.

The program describing the processing contents can be recorded on a computer-readable recording medium. As the computer-readable recording medium, any recording medium such as a magnetic recording device, an optical disk, a magneto-optical recording medium, and a semiconductor memory may be used.

Also, this program is distributed by selling, transferring, or lending a portable recording medium such as a DVD or CD-ROM in which the program is recorded. Furthermore, the program may be distributed by storing the program in a storage device of the server computer and transferring the program from the server computer to another computer via a network.

For example, a computer that executes such a program first stores a program recorded on a portable recording medium or a program transferred from a server computer in its own storage device. When executing the process, the computer reads a program stored in its own recording medium and executes a process according to the read program. As another execution form of the program, the computer may directly read the program from a portable recording medium and execute processing according to the program, and the program is transferred from the server computer to the computer. Each time, the processing according to the received program may be executed sequentially. In addition, the program is not transferred from the server computer to the computer, and the above-described processing is executed by a so-called ASP (Application Service Provider) type service that realizes a processing function only by an execution instruction and result acquisition. It is good. Note that the program in this embodiment includes information that is used for processing by an electronic computer and that conforms to the program (data that is not a direct command to the computer but has a property that defines the processing of the computer).

In this embodiment, the present apparatus is configured by executing a predetermined program on a computer. However, at least a part of these processing contents may be realized by hardware.
