Summary of the Invention [Problem to be solved by the invention]

[0005] In order to prevent the spread of infectious diseases, it is considered useful to properly clean objects that people have come close to or touched. However, JP2015-533248A, WO2013 / 031481A, and JP2017-004165A do not consider cleaning objects that people have come close to or touched.

[0006] The present disclosure has been made in consideration of the above circumstances, and aims to provide an information processing device, an information processing method, an information processing program, and a storage device that can prevent the spread of infectious diseases through objects. [Means for solving the problem]

[0007] The information processing device of the present disclosure is an information processing device having at least one processor, and the processor identifies at least one of an object that a person has come into contact with and an object that a person has approached within a certain distance for a certain period of time or more, and controls the storage of log data in a storage device, the log data being used to notify a request for cleaning the object and including identification information of the identified object.

[0008] In addition, in the information processing device of the present disclosure, the processor may notify a cleaning request for an object whose identification information is included in the log data.

[0009] In addition, the information processing device of the present disclosure may be configured so that the processor issues a cleaning request for an area predetermined as a contamination control area in a hospital at a timing predetermined as a timing when cleaning of an object is possible.

[0010] In addition, the information processing device of the present disclosure may be configured such that, for areas other than those predetermined as contamination control areas within the hospital, the processor may notify a cleaning request at least at a first time when a person who has come into contact with or approached within a certain distance for a certain period of time with an object whose identification information is included in the log data and who is located within that area is found to test positive for an infectious disease and at a second time when it is found to meet the conditions for being suspected of being infected with an infectious disease.

[0011] In addition, the information processing device of the present disclosure may have a processor that notifies a cleaning request for objects that have come into contact with at least one of a person who has tested positive for an infectious disease and a person who has been found to meet conditions for being suspected of being infected with an infectious disease, during a period from at least one of the first timing and the second timing until a second certain period of time, and objects that have come into contact within a certain distance for a certain period of time or more.

[0012] Furthermore, in the information processing device of the present disclosure, the second certain period may be determined according to the maximum remaining period of a pathogen of an infectious disease for each material of the object.

[0013] In addition, the information processing device of the present disclosure may further notify the processor of information representing a person who has come into contact with an uncleaned object within the second certain period from a time when at least one of a person who has tested positive for an infectious disease and a person who has been found to meet the conditions for being suspected of being infected with an infectious disease has come into contact with an object whose identification information is included in the log data or has come within a certain distance for a certain period of time or more at a first time and a second time.

[0014] In addition, in the information processing device of the present disclosure, the processor may further notify a cleaning request for an object that is the subject of a cleaning request and has come into contact with an object that has not yet been cleaned.

[0015] In addition, in the information processing device of the present disclosure, the processor may notify the cleaning request by using different messages at the first timing and the second timing.

[0016] In addition, in the information processing device of the present disclosure, if the identified object is provided with a display device, the processor may notify the object of a cleaning request to be displayed on the display device.

[0017] In addition, in the information processing device of the present disclosure, the processor may delete, from among the logs included in the log data, logs for which an incubation period of an infectious disease pathogen has elapsed since the time the log was acquired.

[0018] Furthermore, in the information processing device according to the present disclosure, when the processor identifies an object, the certain period of time may be variable depending on the protection state of the person.

[0019] In addition, the information processing method disclosed herein is a method in which a processor provided in an information processing device performs a process of controlling the storage of log data in a storage device, the log data including identification information of the identified object, to identify at least one of an object that a person has come into contact with and an object that a person has approached within a certain distance for a certain period of time, and to use the log data to notify a request for cleaning the object.

[0020] In addition, the information processing program disclosed herein is intended to cause a processor provided in an information processing device to execute a process of controlling the storage of log data in a storage device, the log data including identification information of the identified object, which is log data to be used to notify a request for cleaning of the object, and at least one of an object that a person has come into contact with and an object that a person has approached within a certain distance for a certain period of time.

[0021] In addition, the storage device of the present disclosure is a storage device incorporated into an information processing device, and stores log data including identification information of objects identified as at least one of an object that a person has come into contact with and an object that a person has approached within a certain distance for a certain period of time, in order to notify a request for cleaning the object by the information processing device.

[0024] Hereinafter, examples of embodiments for carrying out the technology of the present disclosure will be described in detail with reference to the drawings.

[0025] First, the configuration of an information processing system 10 according to this embodiment will be described with reference to Fig. 1. As shown in Fig. 1, the information processing system 10 includes an information processing device 12 and a plurality of log acquisition devices 14. The information processing device 12 and each log acquisition device 14 are each connected to a network and are capable of communicating with each other. In this embodiment, an example will be described in which the information processing device 12 and each log acquisition device 14 are installed in a hospital.

[0026] The log acquisition device 14 acquires logs of detections of a person coming into contact with an object, a person coming into contact with an object and then moving away from the object, a person approaching within a certain distance from the object, and a person approaching within a certain distance from the object and then moving away from the object by a certain distance or more. The person referred to here is, for example, a patient visiting the hospital, a patient's family, and a medical staff member working at the hospital. The object referred to here is, for example, an imaging device for taking medical images, a control device for controlling the imaging device, and an electrical device such as an operation terminal provided with a touch panel operated by a person. Note that the object is not limited to an electrical device, and may be an object other than an electrical device. In the following, the approach of a person to an object within a certain distance is simply referred to as "approach". In addition, the certain distance (for example, 10 cm) in this case may be predetermined according to, for example, a device used to detect the approach, or may be predetermined according to a hospital policy.

[0027] An example of the log acquisition device 14 is a device that detects the approach of a person and an object by short-distance wireless communication such as an IC (Integrated Circuit) tag. In this case, a person is identified by the individual identification information of an IC tag carried by the person, and an object is identified by the individual identification information of an IC tag reader provided on the object. Another example of the log acquisition device 14 is a device that detects contact between a person and an object by using electromagnetic noise emitted by a smart watch worn by the person on the wrist. Another example of the log acquisition device 14 is a device that detects contact and approach between a person and an object by performing image analysis processing on a video image captured by a camera at a predetermined frame rate. The log acquisition device 14 is not limited to the above examples, and may be a device that performs the above detection by other principles as long as it can detect that a person has contacted an object, that a person has contacted an object and then left the object, that a person has approached an object, and that a person has approached an object and then left the object.

[0028] The log acquisition device 14 transmits the acquired log to the information processing device 12. An example of the log is shown in Fig. 2. As shown in Fig. 2, the log acquired by the log acquisition device 14 includes identification information of a person who has come into contact with or approached an object, identification information of the object, location information indicating the location within the hospital where the object is installed, and a category indicating the contact or approach. Also, as shown in Fig. 2, the log acquired by the log acquisition device 14 further includes a start date and time which is the date and time when the person starts to come into contact with or approach the object, and an end date and time of the contact or approach which is the date and time when the person leaves the object after coming into contact with or approaching the object.

[0029] Next, a hardware configuration of the information processing device 12 according to this embodiment will be described with reference to Fig. 3. As shown in Fig. 3, the information processing device 12 includes a CPU (Central Processing Unit) 20, a memory 21 as a temporary storage area, and a non-volatile storage unit 22. The information processing device 12 also includes a display 23 such as a liquid crystal display, an input device 24 such as a keyboard and a mouse, and a network I / F (InterFace) 25 connected to a network. The CPU 20, the memory 21, the storage unit 22, the display 23, the input device 24, and the network I / F 25 are connected to a bus 27.

[0030] The storage unit 22 is realized by a hard disk drive (HDD), a solid state drive (SSD), a flash memory, or the like. The storage unit 22 as a storage medium stores an information processing program 30. The CPU 20 reads the information processing program 30 from the storage unit 22, expands it in the memory 21, and executes the expanded information processing program 30.

[0031] The storage unit 22 also stores first log data 32 and second log data 34. The first log data 32 and second log data 34 are log data used to notify a request for cleaning an object. Specifically, the first log data 32 includes a log related to the approach and contact of a person in a first area that is predetermined as a contamination control area in the hospital, and the second log data includes a log related to the approach and contact of a person in a second area other than the first area in the hospital. The first log data 32 and the second log data 34 will be described in detail later. For example, the concept of zoning in a hospital can be applied to the division of the hospital into the first area and the second area.

[0032] Next, a functional configuration of the information processing device 12 according to this embodiment will be described with reference to Fig. 4. As shown in Fig. 4, the information processing device 12 includes an acquisition unit 40, a determination unit 42, a memory control unit 44, an extraction unit 46, a notification unit 48, and a deletion unit 50. The CPU 20 executes the information processing program 30 to function as the acquisition unit 40, the determination unit 42, the memory control unit 44, the extraction unit 46, the notification unit 48, and the deletion unit 50.

[0033] The acquisition unit 40 acquires the log transmitted from the log acquisition device 14 via the network I / F 25 .

[0034] The determination unit 42 uses the location information included in the log acquired by the acquisition unit 40 to determine whether the installation location of the object indicated by the object's identification information included in the log is within the first area or the second area. Furthermore, the determination unit 42 determines whether the period from the "start date and time" to the "end date and time" is equal to or longer than a first certain period (e.g., 15 minutes) for logs classified as "approach" among the logs acquired by the acquisition unit 40. The first certain period in this case may be determined in advance according to, for example, the definition of close contact or the hospital policy.

[0035] The storage control unit 44 controls to store, in the first log data 32 of the storage unit 22, a log acquired by the acquisition unit 40, which is classified as "contact" and in which the determination unit 42 has determined that the installation position of the object is within the first area. The storage control unit 44 also controls to store, in the second log data 34 of the storage unit 22, a log acquired by the acquisition unit 40, which is classified as "contact" and in which the determination unit 42 has determined that the installation position of the object is within the second area. That is, in the first log data 32, a log including identification information of an object identified as having been contacted by a person in the first area is accumulated. In addition, in the second log data 34, a log including identification information of an object identified as having been contacted by a person in the second area is accumulated.

[0036] The storage control unit 44 also controls to store, in the first log data 32 of the storage unit 22, a log acquired by the acquisition unit 40, which is classified as "approaching", which is determined by the determination unit 42 that the installation position of the object is within the first area, and which is determined by the determination unit 42 that the period from the "start date and time" to the "end date and time" is equal to or longer than a first certain period. The storage control unit 44 also controls to store, in the second log data 34 of the storage unit 22, a log acquired by the acquisition unit 40, which is classified as "approaching", which is determined by the determination unit 42 that the installation position of the object is within the second area, and which is determined by the determination unit 42 that the period from the "start date and time" to the "end date and time" is equal to or longer than a first certain period. That is, in the first log data 32, a log including identification information of an object that is identified as having been approached by a person within a certain distance for equal to or longer than a first certain period in the first area is accumulated. In addition, the second log data 34 accumulates logs including identification information of objects that are identified as objects that a person has approached within a certain distance in the second area for a first certain period or more. Among the logs acquired by the acquisition unit 40, logs that are classified as "approach" and that are determined by the determination unit 42 to have a period from the "start date and time" to the "end date and time" that is less than the first certain period are discarded. Furthermore, instead of discarding such logs, they may be included in the first log data 32 or the second log data 34 depending on the installation position of the object. In this case, a notification flag may be set only for logs classified as "approach" in the first log data 32 and the second log data 34 that are determined by the determination unit 42 to have a period from the "start date and time" to the "end date and time" that is more than the first certain period.

[0037] The extraction unit 46 extracts, at a first timing when the person whose identification information is included in the second log data 34 is found to have tested positive for an infectious disease, from the second log data 34. The person whose identification information is included in the second log data 34 means a person who at least either touched or approached within a certain distance of the object whose identification information is included in the second log data 34, and was located within a second area.

[0038] The extraction unit 46 also extracts, at a first timing, from the second log data 34, identification information of an object approached by a person whose infectious disease test result is found to be positive. This first timing is, for example, the timing when identification information of a person whose infectious disease test result is positive is input to the information processing device 12.

[0039] Furthermore, at a second timing when it is found that the person whose identification information is included in the second log data 34 satisfies the condition for suspecting infection with an infectious disease, the extraction unit 46 extracts, from the second log data 34, the identification information of an object that the person who is found to satisfy the condition for suspecting infection with an infectious disease has come into contact with. The condition for suspecting infection with an infectious disease is, for example, a predetermined condition such as a body temperature of 37.5 degrees or higher or coughing.

[0040] The extraction unit 46 also extracts, at a second timing, from the second log data 34, the identification information of an object approached by a person who has been found to satisfy the conditions for suspecting infection with an infectious disease. This second timing is, for example, the timing when the identification information of a person who has been found to satisfy the conditions for suspecting infection with an infectious disease is input to the information processing device 12.

[0041] For the first area, the notification unit 48 notifies a cleaning request for an object whose identification information is included in the first log data 32 at a timing that is predetermined as a timing when the object can be cleaned. Examples of this timing include a break time such as a lunch break and a break between inspections.

[0042] Furthermore, for the second region, the notification unit 48 notifies the cleaning request for the object indicated by the identification information extracted by the extraction unit 46 at the first timing and the second timing. At this time, the notification unit 48 notifies the cleaning request for the object that has been in contact with a person who has been found to have tested positive for an infectious disease during the period from the first timing to the second certain period and the object that has been in close proximity for the first certain period or more and has not been cleaned. At this time, the notification unit 48 notifies the cleaning request for the object that has been in contact with a person who has been found to satisfy the conditions for suspecting infection with an infectious disease during the period from the second timing to the second certain period and the object that has been in close proximity for the first certain period or more and has not been cleaned. In this case, the second certain period can be a period determined according to the maximum remaining period of the pathogen of the infectious disease for each material of the object. For example, assuming COVID-19 as the infectious disease, the maximum remaining period of the pathogenic virus is said to be 3 hours on a copper surface and 72 hours on a plastic surface. In this way, the second certain period may be set to the maximum remaining period of the pathogen of the infectious disease for each material of the object, or may be set to the maximum remaining period of the pathogen of the infectious disease with a margin added thereto. Furthermore, when multiple materials are used for the object, the second certain period may be determined according to the material with the longest maximum remaining period among the multiple materials.

[0043] An example of a notification process of a cleaning request for an object at a first timing will be described with reference to Fig. 5. The horizontal axis of Fig. 5 represents time, and the circles represent an object whose identification information is included in the second log data 34 and the timing when a person who has tested positive for an infectious disease came into contact with the object or approached the object for a first certain period of time or longer. The dashed arrow pointing left in Fig. 5 represents a second certain period of time. Fig. 5 also shows the timing when the cleaning was performed for objects that have been cleaned.

[0044] In the example of FIG. 5, the cleaning request is not notified for objects A, B, and E because the timing when a person who tested positive for an infectious disease came into contact with or approached for more than a first certain period of time was before the second certain period from the first timing. In addition, the timing when a person who tested positive for an infectious disease came into contact with or approached for more than a first certain period of time was within the second certain period from the first timing for object D, but cleaning was performed after the contact or approach, so the cleaning request is not notified. In addition, the timing when a person who tested positive for an infectious disease came into contact with or approached for more than a first certain period of time was within the second certain period from the first timing for objects C and F, and cleaning has not been performed, so the cleaning request is notified. In FIG. 5, an example at the first timing is shown, but the same applies to the second timing. Whether an object has been cleaned can be determined, for example, by associating a flag indicating whether it has been cleaned with the identification information of the object.

[0045] In this embodiment, the notification unit 48 notifies the cleaning request by sending a message of the cleaning request to a mobile information terminal carried by a person in charge who is predetermined as the manager of the object. An example of this message is, for example, a message such as "Please clean object A installed at place A." The notification unit 48 may also notify the cleaning request by sending an e-mail of the cleaning request to an e-mail address of the person in charge who is predetermined as the manager of the object. The notification unit 48 may also notify the cleaning request by blinking an LED (Light Emitting Diode) lamp provided on the object. If a display device is provided on the object, the notification unit 48 may also notify the cleaning request to be displayed on the display device. These multiple notification methods may also be combined.

[0046] The deletion unit 50 deletes, at regular intervals such as once a day, from among the logs included in the first log data 32 and the second log data 34, logs for which the upper limit of the incubation period of the pathogen of the infectious disease has passed since the time of log acquisition. When multiple infectious diseases are assumed, the deletion unit 50 deletes, from among the logs included in the first log data 32 and the second log data 34, logs for which the longest incubation period of the infectious disease has passed since the time of log acquisition. Note that the deletion unit 50 may delete logs for which a period of time equal to the incubation period of the pathogen of the infectious disease plus a margin has passed since the time of log acquisition.

[0047] Next, the operation of the information processing device 12 according to the present embodiment will be described with reference to Figs. 6 to 10. The CPU 20 executes the information processing program 30, thereby executing a log storage process shown in Fig. 6, a first cleaning request notification process shown in Fig. 7, a second cleaning request notification process shown in Fig. 8, a third cleaning request notification process shown in Fig. 9, and a log deletion process shown in Fig. 10. The log storage process shown in Fig. 6 is executed, for example, every time the information processing device 12 receives a log transmitted from the log acquisition device 14. The first cleaning request notification process shown in Fig. 7 is executed at a timing that is predetermined as a timing when cleaning of an object is possible, such as a lunch break and between inspections. The second cleaning request notification process shown in Fig. 8 is executed, for example, at the first timing described above. The third cleaning request notification process shown in Fig. 9 is executed, for example, at the second timing described above. The log deletion process shown in Fig. 10 is executed at a regular timing, such as once a day.

[0048] 6, the acquisition unit 40 acquires the log transmitted from the log acquisition device 14 via the network I / F 25. In step S12, the determination unit 42 determines whether the category of the log acquired in step S10 is “approach.” If this determination is positive, the process proceeds to step S14.

[0049] In step S14, the determination unit 42 determines whether the period from the "start date and time" to the "end date and time" of the log acquired in step S10 is equal to or longer than a first certain period. If this determination is positive, the process proceeds to step S16. If the determination in step S12 is negative, the process proceeds to step S16.

[0050] In step S16, the determination unit 42 uses the position information included in the log acquired in step S10 to determine whether or not the installation position of the object indicated by the object's identification information included in the log is within the first area. If this determination is a positive determination, the process proceeds to step S18. In step S18, the memory control unit 44 performs control to store the log acquired in step S10 in the first log data 32 of the memory unit 22. When the process of step S18 ends, the log storage process ends.

[0051] On the other hand, if the determination in step S16 is a negative determination, the process proceeds to step S20. In step S20, the memory control unit 44 performs control to store the log acquired in step S10 in the second log data 34 of the memory unit 22. When the process in step S20 ends, the log storage process ends. Also, if the determination in step S14 is a negative determination, the log storage process ends.

[0052] 7, as described above, the notification unit 48 notifies a cleaning request for an object whose identification information is included in the first log data 32. When the process of step S30 ends, the first cleaning request notification process ends.

[0053] In step S40 of Fig. 8, the extraction unit 46 extracts, from the second log data 34, identification information of an object that has been in contact with a person whose infectious disease test result has been found to be positive. Furthermore, the extraction unit 46 also extracts, from the second log data 34, identification information of an object that has been approached by a person whose infectious disease test result has been found to be positive. In step S42, the extraction unit 46 notifies a cleaning request for the object indicated by the identification information extracted in step S40, as described above. When the processing of step S42 ends, the second cleaning request notification processing ends.

[0054] In step S50 of FIG. 9, the extraction unit 46 extracts, from the second log data 34, identification information of an object that has been in contact with a person who has been found to satisfy the conditions for suspecting infection with an infectious disease. Furthermore, the extraction unit 46 also extracts, from the second log data 34, identification information of an object that has been approached by a person who has been found to satisfy the conditions for suspecting infection with an infectious disease. In step S52, the extraction unit 46 notifies a cleaning request for the object indicated by the identification information extracted in step S50, as described above. When the processing of step S52 ends, the third cleaning request notification processing ends.

[0055] 10, as described above, the deletion unit 50 deletes logs for which the upper limit of the incubation period of the pathogen of the infectious disease has passed since the log acquisition time point, from among the logs included in the first log data 32 and the second log data 34. When the process of step S60 ends, the log deletion process ends.

[0056] As described above, according to this embodiment, a request to clean an object is appropriately notified, thereby making it possible to prevent the spread of infectious diseases via the object.

[0057] In the above embodiment, the notification unit 48 may further notify information representing a person who, at the first timing, contacted an uncleaned object within a second certain period after a person who has been found to have tested positive for an infectious disease contacted or approached an object whose identification information is included in the log data 34 for a first certain period. In this case, the notification unit 48 may notify a mobile information terminal carried by the person of a message recommending disinfection, such as "Please wash your hands as you have come into contact with a potentially contaminated object." In addition, the notification unit 48 may further notify information representing a person who, at the second timing, contacted an uncleaned object within a second certain period after a person who has been found to have tested positive for an infectious disease contacted or approached an object whose identification information is included in the log data 34 for a first certain period.

[0058] With reference to FIG. 11, an example of a notification process of a cleaning request for an object at a first timing in this embodiment will be described. The horizontal axis of FIG. 11 represents time, and a circle represents an object whose identification information is included in the second log data 34 and a timing when a person who has tested positive for an infectious disease contacts the object or approaches the object for a first certain period of time or more. Also, a dashed arrow pointing left and a dashed arrow pointing right in FIG. 11 represent a second certain period of time. Also, in FIG. 11, for an object that has been cleaned, the timing of cleaning is also shown. Also, a triangular mark in FIG. 11 represents a person who has contacted an object in the same row. For example, a person A in FIG. 11 represents a person who has contacted an object A after cleaning of the object A has been performed.

[0059] In the example of FIG. 11, person A is not subject to notification because he comes into contact with object A after object A has been cleaned. Person B is subject to notification because he comes into contact with object B within a second fixed period of time after a person who has tested positive for an infectious disease has come into contact with or approached object B for a first fixed period of time or more. Person C is not subject to notification because he comes into contact with object E after a second fixed period of time has elapsed after a person who has tested positive for an infectious disease has come into contact with or approached object E for a first fixed period of time or more. FIG. 11 shows an example at the first timing, but the same applies to the second timing.

[0060] In the above embodiment, the notification unit 48 may further notify, at the first timing and the second timing, a cleaning request for an object that is the subject of a cleaning request and has come into contact with an object that has not been cleaned. In this embodiment, as shown in Fig. 12 as an example, a cleaning request for an object G that is the subject of a cleaning request and has come into contact with an object F that has not been cleaned is also notified. Contact between objects occurs, for example, when objects are stored in a stacked state.

[0061] In the above embodiment, the notification unit 48 may notify the cleaning request with different messages at the first timing and the second timing. In this case, at the first timing, the notification unit 48 notifies a cleaning request instructing cleaning, such as a message such as "This object is in contact with or close to a person who tested positive for an infectious disease, so please clean it." On the other hand, in this case, the notification unit 48 notifies a cleaning request with a lower warning level than the first timing, at the second timing. Specifically, in this case, the notification unit 48 notifies a cleaning request recommending cleaning, such as a message such as "This object is in contact with or close to a person suspected of being infected with an infectious disease, so we recommend cleaning it."

[0062] In the above embodiment, the determination unit 42 may vary the first certain period according to the protection state of the person. In this case, for example, the determination unit 42 may set the first certain period longer for a person wearing a mask than for a person not wearing a mask. Whether or not a person can wear a mask can be determined by, for example, performing image analysis processing on an image obtained by photographing the person with a camera.

[0063] In the above embodiment, the determination unit 42 may vary the first certain period according to the disinfection state of the person. In this case, for example, the determination unit 42 may set the first certain period shorter for a person who does not wash his / her hands sufficiently than for a person who washes his / her hands sufficiently. Whether or not hand washing is sufficient can be determined, for example, by a function of a wearable device such as a smart watch. For example, whether or not hand washing is sufficient is determined depending on whether or not the period of hand washing is equal to or longer than a predetermined threshold.

[0064] In the above embodiment, logs classified as "contact" may be controlled to be stored in the storage unit 22 as logs classified as "approach", if the period from the "start date and time" to the "end date and time" is equal to or longer than a certain period. In this case, logs classified as "contact" and with a period from the "start date and time" to the "end date and time" that is less than the certain period are discarded. The certain period in this case may be the same as the first certain period, or may be shorter than the first certain period.

[0065] In the above embodiment, the following various processors can be used as the hardware structure of the processing units that execute various processes, such as the acquisition unit 40, the determination unit 42, the storage control unit 44, the extraction unit 46, the notification unit 48, and the deletion unit 50. As described above, the above various processors include a CPU, which is a general-purpose processor that executes software (programs) and functions as various processing units, as well as a programmable logic device (PLD), which is a processor whose circuit configuration can be changed after manufacture, such as an FPGA (Field Programmable Gate Array), a dedicated electric circuit, which is a processor having a circuit configuration designed specifically for executing specific processes, such as an ASIC (Application Specific Integrated Circuit), etc.

[0066] A single processing unit may be configured with one of these various processors, or may be configured with a combination of two or more processors of the same or different types (for example, a combination of multiple FPGAs, or a combination of a CPU and an FPGA). Also, multiple processing units may be configured with a single processor.

[0067] As an example of configuring multiple processing units with one processor, first, there is a form in which one processor is configured with a combination of one or more CPUs and software, as typified by computers such as client and server, and this processor functions as multiple processing units. Second, there is a form in which a processor is used that realizes the functions of the entire system including multiple processing units with one IC (Integrated Circuit) chip, as typified by System on Chip (SoC), etc. In this way, the various processing units are configured using one or more of the above various processors as a hardware structure.

[0068] Furthermore, more specifically, the hardware structure of these various processors can be an electric circuit that combines circuit elements such as semiconductor elements.

[0069] In the above embodiment, the information processing program 30 is stored (installed) in advance in the storage unit 22, but the present invention is not limited to this. The information processing program 30 may be provided in a form recorded on a recording medium such as a CD-ROM (Compact Disc Read Only Memory), a DVD-ROM (Digital Versatile Disc Read Only Memory), or a USB (Universal Serial Bus) memory. The information processing program 30 may be downloaded from an external device via a network.
