<1. Overview of Information Processing Apparatus According to One Embodiment of Present Disclosure>
First, an overview of an information processing apparatus according to an embodiment of the present disclosure will be described with reference to FIG. FIG. 1 is a diagram for describing an overview of an information processing apparatus according to an embodiment of the present disclosure.

The information processing apparatus 100 is a mobile communication terminal having a communication function and a data synchronization function. Data synchronization is performed when data to be shared is generated or updated. Therefore, the information processing apparatus 100 can share data by synchronizing data generated or updated through communication with other information processing apparatuses and the like.

For example, as illustrated in FIG. 1, the information processing apparatus 100 can acquire image data generated by the camera 200 having a communication function by synchronizing data through communication.

Here, when data is synchronized every time data is generated or updated, the amount of communication increases and the amount of power consumption increases. On the other hand, when the data is synchronized when the data is accessed, a waiting time until the data synchronization is completed occurs. Therefore, the information processing apparatus 100 performs synchronization (hereinafter also referred to as update synchronization) for some data when the data is generated or updated, and a user operation or the like is performed for data other than the some data. Synchronization (hereinafter also referred to as speculative synchronization) is performed when a predetermined condition is satisfied. In addition, the information processing apparatus 100 stores data that is estimated to be more likely to be used in the near future when a user operation satisfying a predetermined condition is performed based on a user operation history or the like, compared to other data. When the predetermined condition is satisfied, the data is determined as data synchronized by speculative synchronization.

For example, as illustrated in FIG. 1, when an image data storage directory is generated in the information processing apparatus 100, the information processing apparatus 100 synchronizes the changed directory structure with the camera 200. Thereafter, the main body of the image data and the thumbnails A to F related to the image data can be generated in the synchronized image data storage directory in the camera 200 by imaging. When an operation for starting an image browsing application is performed in the information processing apparatus 100, the information processing apparatus 100 synchronizes the thumbnails A to F stored in the image data storage directory. Further, when an operation for starting the thumbnail browsing screen is performed in the information processing apparatus 100, the information processing apparatus 100 displays the synchronized thumbnails A to F and synchronizes the main body of the image data related to the thumbnails A to F. Do.

As described above, the information processing apparatus 100 according to an embodiment of the present disclosure synchronizes a part of data when the data is generated or updated. For data other than the part of the data, the information processing apparatus 100 is more likely to be used in the near future of the data when a user operation or the like satisfies a predetermined condition. The data estimated to be high is synchronized. For this reason, it is possible to suppress the occurrence of a waiting time related to data synchronization by performing data synchronization prior to the timing at which the data is used. 1 illustrates a smart watch as an example of the information processing apparatus 100, the information processing apparatus 100 may be a smartphone, a tablet terminal, a PDA (Personal Digital Assistant), or the like. For convenience of explanation, each of the information processing apparatuses 100 according to the first and second embodiments is suffixed with a number corresponding to the embodiment, like the information processing apparatuses 100-1 and 100-2. To distinguish.

<2. First Embodiment of the Present Disclosure>
[2-1. Configuration of Information Processing Device According to First Embodiment of Present Disclosure]
The overview of the information processing apparatus 100 according to an embodiment of the present disclosure has been described above. Next, the configuration of the information processing apparatus 100-1 according to the first embodiment of the present disclosure will be described with reference to FIG. FIG. 2 is a block diagram illustrating a schematic functional configuration of the information processing apparatus 100-1 according to the first embodiment of the present disclosure.

As shown in FIG. 2, the information processing apparatus 100-1 includes an operation detection unit 102, an application 104, a storage unit 106, a determination unit 108, a synchronization execution unit 110, and a communication unit 118.

The operation detection unit 102 detects a user operation on the information processing apparatus 100-1. Specifically, the operation detection unit 102 detects an operation on the information processing apparatus 100-1 based on input information obtained from an input apparatus operated by the user. Furthermore, the operation detection unit 102 stores the detected user operation in the storage unit 106 so that the time series can be understood. For example, the operation detection unit 102 can cause the storage unit 106 to store the detected user operation and the time when the user operation is detected. The user operation may be application activation, pause or termination, file generation, editing or deletion, lock setting or release, login, logout, screen touch, or the like.

Application 104 performs processing based on user operation. Specifically, the application 104 determines a process to be performed based on a user operation detected by the operation detection unit 102, and executes the determined process. In addition, the application 104 accesses data stored in the storage unit 106 in accordance with the content of processing. Further, when the application 104 generates or updates data, the application 104 stores the data in the storage unit 106. In addition, when access to data stored in the storage unit 106 is performed in the execution of the process, the application 104 associates data access information indicating the accessed data with the user operation related to the process and stores it in the storage unit 106. Remember me.

The storage unit 106 stores data and information related to data synchronization. Specifically, the storage unit 106 speculatively uses data generated by the application 104 and the operation of the update synchronization execution table 10 used for the operation of the update synchronization execution unit 112 described later and the speculative synchronization execution unit 116 described later. The synchronous execution table 20 is stored. In addition, the storage unit 106 notifies the determination unit 108 when data is generated or updated. Specifically, the storage unit 106 notifies the determination unit 108 of the difference information of the file system data generated by the data generation or update by the application 104 for each data constituting the file system data. For example, when the application 104 generates a new file, the storage unit 106 stores the directory structure that is a part of the data constituting the file system data changed by the generation of the new file, the file attribute of the new file, and the file body of the new file. The determination unit 108 is notified of each piece of information. As described above, the storage unit 106 notifies the determination unit 108 of difference information for each data constituting the file system data. Furthermore, the synchronization execution unit 110 described later performs synchronization for each data constituting the file system data based on the discrimination result for each data constituting the file system data of the discrimination unit 108. For this reason, it is possible to reduce the amount of communication related to one-time data synchronization by avoiding simultaneous synchronization of the entire file system data.

When the data is generated or updated, the determination unit 108 determines whether the data is a target for update synchronization. Specifically, when the determination unit 108 receives a data generation or update notification from the storage unit 106, the determination unit 108 refers to the update synchronization execution table stored in the storage unit 106 and the data related to the notification is updated synchronously. Determine whether it is a target. For example, a description will be given with reference to FIG. FIG. 3 is a diagram illustrating an example of the update synchronization execution table 10 of the information processing apparatus 100-1 according to the first embodiment of the present disclosure.

First, when data is newly stored or when stored data is updated, the storage unit 106 notifies the determination unit 108 of data generation or update. For example, when a new file is generated, the storage unit 106 notifies the determination unit 108 of the updated directory structure, the file attribute of the new file, and information on the file body of the new file.

Next, the determination unit 108 refers to the update synchronization execution table 10 to determine whether the data related to the notification is a target of update synchronization. The update synchronization execution table 10 has a data name and an update synchronization flag for each data type. The update synchronization flag is a flag used for determining whether to perform update synchronization. For example, as shown in FIG. 3, the update synchronization execution table 10 has a directory structure and file attributes as the data name, the directory structure has the update synchronization flag valid, and the file attribute has the update synchronization flag invalid. It can be. Therefore, for example, when the storage unit 106 is notified of the directory structure, file attributes, and file body information, the determination unit 108 refers to the update synchronization execution table 10 and the directory structure is subject to update synchronization. It is determined that the attribute and the file body are not subject to update synchronization.

Here, returning to the description of the configuration of the information processing apparatus 100-1 with reference to FIG. 2, the synchronization execution unit 110 is based on the synchronization information of data obtained from other information processing apparatuses. Synchronize data of Specifically, when the synchronization execution unit 110 receives the synchronization information of the data received by the communication unit 118 from another information processing apparatus, the synchronization execution unit 110 generates or updates the data related to the synchronization information of the data to the storage unit 106. Do. Furthermore, the synchronization execution unit 110 stores information for identifying the information processing apparatus that is the transmission source of the data synchronization information in the storage unit 106 in association with the data.

Also, the synchronization execution unit 110 includes an update synchronization execution unit 112, a determination unit 114, and a speculative synchronization execution unit 116. The update synchronization execution unit 112 and the speculative synchronization execution unit 116 are a first synchronization execution unit and a second synchronization execution unit in the claims.

The update synchronization execution unit 112 performs update synchronization based on the determination result of the determination unit 108. Specifically, the update synchronization execution unit 112 causes the communication unit 118 to transmit data determined to be update synchronization by the determination unit 108 to another information processing apparatus that can communicate. Note that the data determined to be update synchronous is the first data in the claims.

The determination unit 114 determines conditions and data for periodically performing speculative synchronization based on a history related to processing input of the information processing apparatus. Specifically, the determination unit 114 analyzes the user operation and the history of the data access information associated with the user operation, the condition and data for performing speculative synchronization derived from the analysis result, and the data associated with the data. The speculative synchronization execution table 20 indicating the synchronization target device is generated and updated. For example, a description will be given with reference to FIG. FIG. 4 is a diagram illustrating an example of the speculative synchronization execution table 20 of the information processing apparatus 100-1 according to the first embodiment of the present disclosure. The data determined by the determination unit is the second data in the claims.

First, the determination unit 114 acquires a user operation stored in the storage unit 106 and a history of data access information associated with the user operation. Next, the determination unit 114 analyzes the acquired history, and derives a condition for user operation and data to be synchronized when the condition is satisfied. Then, the determination unit 114 acquires information on another information processing apparatus having the derived data from the storage unit 106. For example, as a result of analyzing the acquired history, the determination unit 114 performs a process involving access to data “file attribute of a file in the image data storage directory” after a user operation “launch an image browsing application”. It can be derived that the frequency of being performed is higher than a predetermined criterion, for example. Next, the determination unit 114 acquires information on the other information processing device “digital camera X” having the derived data from the identification information of the information processing device associated with the data stored in the storage unit 106. To do. Then, as illustrated in FIG. 4, on the condition that the user operation is performed, the determination unit 114 speculatively synchronizes the row in which the data is the synchronization target data and the synchronization target device is “digital camera X”. It adds to the execution table 20. A data analysis method such as general data mining can be used for the analysis of the history of the user operation and the like.

As described above, the determination unit 114 determines conditions and data for performing speculative synchronization periodically based on the history of user operations. For this reason, when a user operation that satisfies the determined condition is performed, the determined data is synchronized, so that it becomes easier to synchronize before the use timing of the data by an application or the like. It is possible to suppress the occurrence of waiting time. Further, by using the user operation as a condition for performing speculative synchronization, it is possible to perform synchronization only for data that is likely to be accessed in the future due to the user operation.

In the above description, an example in which the condition for performing speculative synchronization is one user operation has been described. However, the condition for performing speculative synchronization may be a condition in which a plurality of user operations are combined. For example, the condition for performing speculative synchronization may be that “thumbnail browsing is selected” after “the image browsing application is activated”. For this reason, by determining data for which speculative synchronization is performed by a combination of a plurality of user operations, the data may be used more than when data for speculative synchronization is determined by a single user operation. It is possible to synchronize high data.

Returning to the description of the configuration of the information processing apparatus 100-1 with reference to FIG. 2, the speculative synchronization execution unit 116 periodically stores data based on the user operation history and the speculative synchronization execution table 20. Synchronize. Specifically, when the time for performing speculative synchronization comes, the speculative synchronization execution unit 116 refers to the history of user operations stored in the storage unit 106, and the speculative synchronization execution table 20 satisfies the condition. Check the data to be synchronized for each row. When the confirmed data is data generated or updated by the information processing apparatus 100-1, the speculative synchronization execution unit 116 acquires the confirmed data from the storage unit 106, and synchronizes the data with the communication unit 118. Transmit to the target device. When the confirmed data is data generated or updated by another information processing apparatus, the speculative synchronization execution unit 116 creates a synchronization request for the confirmed data and sends the synchronization request to the communication unit 118. Transmit to the synchronization target device.

In the above description, the example in which the determination unit 114 and the speculative synchronization execution unit 116 perform processing periodically has been described. However, the determination unit 114 and the speculative synchronization execution unit 116 may replace the processing in the above example, or Along with the processing in the above example, processing may be performed based on an event that has occurred. For example, the determination unit 114 and the speculative synchronization execution unit 116 can perform processing based on a user operation. For this reason, it is possible to efficiently synchronize data according to the situation of the information processing apparatus 100-1 by updating the speculative synchronization execution table 20 in accordance with the event that occurs and executing speculative synchronization. Is possible

The communication unit 118 transmits / receives data to be synchronized with other information processing apparatuses. Specifically, the communication unit 118 transmits data to be synchronized or a synchronization request to the synchronization target device based on instructions from each of the update synchronization execution unit 112 and the speculative synchronization execution unit 116. In addition, the communication unit 118 receives data information to be synchronized from another information processing apparatus and passes it to the synchronization execution unit 110.

[2-2. Processing of Information Processing Device in First Embodiment of Present Disclosure]
Next, the process of the information processing apparatus 100-1 according to the first embodiment of the present disclosure will be described. The information processing apparatus 100-1 performs update synchronization and speculative synchronization processing. Therefore, each of update synchronization and speculative synchronization processing will be described.

(Update synchronization processing)
First, update synchronization processing of the information processing apparatus 100-1 will be described with reference to FIG. FIG. 5 is a flowchart conceptually showing the update synchronization processing of the information processing apparatus 100-1 according to the first embodiment of the present disclosure. Note that a description overlapping the description of the configuration of the information processing apparatus 100-1 is omitted.

First, the information processing apparatus 100-1 waits until data is generated or updated (step S302). Specifically, when data is generated or updated by the application 104, the storage unit 106 detects the generation or update of the data.

When data is generated or updated in step S302, the determination unit 108 determines whether the update synchronization flag of the generated or updated data is valid (step S304). Specifically, when data is generated or updated, the storage unit 106 notifies the determination unit 108 of information on the data, and the determination unit 108 refers to the update synchronization execution table 10 and stores the data. The update synchronization flag is determined.

If it is determined in step S304 that the update synchronization flag of the generated or updated data is valid, the update synchronization execution unit 112 checks whether there is another information processing apparatus capable of communication ( Step S306). Specifically, the update synchronization execution unit 112 notifies the communication unit 118 of a confirmation instruction as to whether there is another information processing apparatus that can communicate. Then, the communication unit 118 confirms another information processing apparatus that can communicate based on the notification, and returns a confirmation result to the update synchronization execution unit 112.

If it is determined in step S306 that there is another information processing apparatus that can communicate, the update synchronization execution unit 112 synchronizes the generated or updated data (step S308). Specifically, the update synchronization execution unit 112 passes the synchronization target data to the communication unit 118, and the communication unit 118 transmits the received synchronization target data to another information processing apparatus capable of communication.

(Speculative synchronization processing)
Next, speculative synchronization processing of the information processing apparatus 100-1 will be described with reference to FIG. FIG. 6 is a flowchart conceptually showing the speculative synchronization processing of the information processing apparatus 100-1 according to the first embodiment of the present disclosure. Note that a description overlapping the description of the configuration of the information processing apparatus 100-1 is omitted.

First, the information processing apparatus 100-1 waits until the speculative synchronization execution time comes (step S402).

When the execution time of speculative synchronization has arrived, the speculative synchronization execution unit 116 acquires an operation history (step S404). Specifically, the speculative synchronization execution unit 116 acquires a history of user operations stored in the storage unit 106.

Next, the speculative synchronization execution unit 116 selects a row from the speculative synchronization execution table 20 (step S406). Specifically, the speculative synchronization execution unit 116 refers to the speculative synchronization execution table 20 stored in the storage unit 106 and selects one row of the table. For example, the speculative synchronization execution unit 116 can select the first row of the speculative synchronization execution table 20.

Next, the speculative synchronization execution unit 116 determines whether the condition is satisfied (step S408). Specifically, the speculative synchronization execution unit 116 extracts the most recent user operation from the user operation history acquired from the storage unit 106, and the condition in the row of the speculative synchronization execution table 20 selected by the extracted user operation It is determined whether or not Note that the most recent user operation may be a user operation performed during a period from the current time to a time that is a predetermined time backward.

If it is determined in step S408 that the condition is satisfied, the speculative synchronization execution unit 116 checks whether there is a synchronization target device that can communicate (step S410). Specifically, the speculative synchronization execution unit 116 notifies the communication unit 118 of a confirmation instruction as to whether or not there is a synchronization target device that can communicate. Then, the communication unit 118 confirms a synchronization target device that can communicate based on the notification, and returns a confirmation result to the speculative synchronization execution unit 116.

When it is confirmed in step S410 that there is a communication target device that can communicate, the speculative synchronization execution unit 116 synchronizes data to be synchronized (step S412). Specifically, when the synchronization target data is data generated or updated in the information processing apparatus 100-1, the speculative synchronization execution unit 116 passes the synchronization target data to the communication unit 118. When the data to be synchronized is not data generated or updated in the information processing apparatus 100-1, the speculative synchronization execution unit 116 generates a synchronization request for the data and passes the synchronization request to the communication unit 118. . Then, the communication unit 118 transmits the received synchronization target data or synchronization request to a synchronization target apparatus capable of communication.

Next, the speculative synchronization execution unit 116 determines whether the selected row is the last row of the speculative synchronization execution table 20 (step S412). Specifically, the speculative synchronization execution unit 116 determines whether the selected row in the current speculative synchronization execution table 20 is the last row in the speculative synchronization execution table 20.

If it is determined in step S412 that the selected row is not the last row of the speculative synchronization execution table 20, the process returns to step S406. If it is determined that the selected row is the last row of the speculative synchronization execution table 20, the process ends. In the above description, an example in which processing related to data synchronization is performed for all rows of the speculative synchronization execution table 20 has been described. However, the speculative synchronization execution unit 116 may Only one or two or more predetermined rows may be processed.

As described above, according to the first embodiment of the present disclosure, the information processing apparatus 100-1 performs synchronization of update synchronization target data in response to generation or update of the data. In addition, when a user operation that satisfies a condition derived based on a user operation history is performed, the information processing apparatus 100-1 is estimated to be used by a user operation performed after the user operation. Synchronize data. As described above, the synchronization of the data is performed before the timing at which the data is used, so that it is possible to suppress the occurrence of the waiting time related to the synchronization of the data.

[2-3. Modification of First Embodiment of Present Disclosure]
Heretofore, the first embodiment of the present disclosure has been described. In addition, this embodiment is not limited to the above-mentioned example. Hereinafter, first to sixth modifications of the present embodiment will be described.

(First modification)
As a first modification of the present embodiment, the determination unit 114 may determine a condition and data for performing speculative synchronization based on the data access history. Specifically, the determination unit 114 analyzes the data access history, speculative synchronization execution table indicating the conditions and data for performing speculative synchronization derived from the analysis result, and the synchronization target device associated with the data 20 generations and updates. For example, a description will be given with reference to FIG. FIG. 7 is a diagram illustrating an example of the speculative synchronization execution table 22 of the information processing apparatus 100-1 according to the first modification example of the first embodiment of the present disclosure.

First, when data access is performed by the application 104, the storage unit 106 stores information on the data access so that the time series can be understood. Then, the determination unit 114 acquires a history of data access information stored in the storage unit 106. Next, the determination unit 114 analyzes the acquired history, and derives data access conditions and data to be synchronized when the conditions are satisfied. Then, the determination unit 114 acquires information on another information processing apparatus having the derived data from the storage unit 106. For example, as a result of analyzing the history of the acquired data access information, the determination unit 114 determines that the frequency with which the process involving the access to the “file attribute of the file B” is performed after the access to the “file A” is, for example, a predetermined value It can be derived that it is higher than the reference. Next, the determination unit 114 acquires information of the information processing device “smartphone Y” having the derived data from the identification information of the information processing device associated with the data stored in the storage unit 106. Then, as illustrated in FIG. 7, on the condition that access to “file A” is performed, the determination unit 114 sets “file attribute of file B” as synchronization target data, and sets the synchronization target device as “smartphone Y”. Are added to the speculative synchronization execution table 22.

Then, the speculative synchronization execution unit 116 performs data synchronization based on the data access information and the speculative synchronization execution table 22. For example, the speculative synchronization execution unit 116 extracts data access information performed during a period from a current time to a time that is a predetermined time later from the history of data access information stored in the storage unit 106, and data synchronization Can be used to determine the row of the speculative synchronization execution table 22.

In this way, the determination unit 114 determines the condition and data for performing speculative synchronization based on the history of data access information. Therefore, by using only the history of data access information, it is possible to reduce the storage capacity of the storage unit 106 used as compared with the case of using the history of user operations.

(Second modification)
As a second modification of the present embodiment, the determination unit 114 may determine a condition and data for performing speculative synchronization based on the physical state of the information processing apparatus 100-1. Specifically, the information processing apparatus 100-1 further includes a sensor and a state detection unit that detects a physical state of the information processing apparatus 100-1 based on information obtained from the sensor. Based on the detection result of the state detection unit, the condition and data for performing speculative synchronization are determined. For example, a description will be given with reference to FIG. FIG. 8 is a diagram illustrating an example of the speculative synchronization execution table 24 of the information processing device 100-1 according to the second modification example of the first embodiment of the present disclosure.

First, the state detection unit detects the physical state of the information processing apparatus 100-1 based on information obtained from the sensor. For example, the sensor is an acceleration sensor, and the state detection unit detects that the information processing apparatus 100-1 has been moved when acceleration information is obtained from the acceleration sensor. Then, the state detection unit causes the storage unit 106 to store the detected physical state of the information processing apparatus 100-1 and the detection time. Further, when data access is performed by the application 104, the storage unit 106 stores information on the data access and access time. In the above, the example in which the sensor is an acceleration sensor has been described. However, the sensor is an angular velocity sensor, a positioning meter, a geomagnetic sensor, an orientation sensor, a luminance sensor, a pressure sensor, a temperature sensor, a proximity sensor, a gaze sensor, a heart rate monitor, It may be a camera, a microphone, a touch sensor, or the like.

Then, when the processing time of the determination unit 114 arrives, the determination unit 114 acquires the physical state and detection time of the information processing apparatus 100-1 and the data access information and access time stored in the storage unit 106 To do. Next, the determination unit 114 analyzes the acquired information, derives the physical state condition of the information processing apparatus 100-1 and data that is synchronized when the condition is satisfied, and the derived data The information of another information processing apparatus having the information is acquired from the storage unit 106. For example, as a result of analyzing the acquired information, the determination unit 114 performs a process with access to the “file attribute of the file in the image data storage directory” after “the information processing apparatus 100-1 has been moved”. For example, can be derived to be higher than a predetermined criterion. Next, the determination unit 114 acquires information of the information processing apparatus “digital camera X” having the derived data from the identification information of the information processing apparatus associated with the data stored in the storage unit 106. Then, as shown in FIG. 8, the determination unit 114 sets the “file attribute of the file in the image data storage directory” as the synchronization target data on the condition that the “information processing apparatus 100-1 has been moved” is detected. Then, a row in which the synchronization target device is “digital camera X” is added to the speculative synchronization execution table 24.

Then, the speculative synchronization execution unit 116 performs data synchronization based on the detection result of the state detection unit and the speculative synchronization execution table 24. For example, the speculative synchronization execution unit 116 detects the physical information processing apparatus 100-1 detected during the period from the history of data access information stored in the storage unit 106 to a time that is a predetermined time after the current time. The state can be extracted and used to determine the row of the speculative synchronization execution table 24 that performs data synchronization.

As described above, the determination unit 114 determines the conditions and data for performing speculative synchronization based on the physical state of the information processing apparatus 100-1. For this reason, the synchronization is performed at the stage of the preliminary operation of the user operation with respect to the information processing apparatus 100-1, so that the data synchronization can be easily completed by the data use timing.

(Third Modification)
As a third modification of the present embodiment, the speculative synchronization execution unit 116 may perform speculative synchronization based on the resource usage state of the information processing apparatus 100-1. Specifically, the speculative synchronization execution unit 116 acquires the resource usage state of the information processing apparatus 100-1 and performs speculative synchronization when the acquired resource usage state satisfies a predetermined condition. More specifically, a description will be given with reference to FIG. FIG. 9 is a diagram illustrating an example of the speculative synchronization execution table 26 of the information processing device 100-1 according to the third modification example of the first embodiment of the present disclosure.

First, when the time for performing speculative synchronization comes, the speculative synchronization execution unit 116 acquires the resource usage status from the OS of the information processing apparatus 100-1. For example, the resource usage state may be a CPU, memory or network resource usage state, or a remaining battery level.

Then, the speculative synchronization execution unit 116 determines whether the use state of the acquired resource satisfies the condition indicated in the speculative synchronization execution table 26. For example, as shown in FIG. 9, the condition indicated in the speculative synchronization execution table 26 may be “the remaining battery level is 90% or more and the signal strength is −40 dBm or more”.

Then, when it is determined that the usage state of the acquired resource satisfies the condition shown in the speculative synchronization execution table 26, the speculative synchronization execution unit 116 checks whether there is a communicable synchronization target device. When the presence of a communicable synchronization target device is confirmed, the speculative synchronization execution unit 116 sends the synchronization target data indicated in the speculative synchronization execution table 26 to the synchronization target device that can communicate with the communication unit 118. To send. For example, as shown in FIG. 9, the synchronization target data may be “file attributes and file bodies of all files to be shared”.

In this way, the speculative synchronization execution unit 116 performs speculative synchronization based on the resource usage state of the information processing apparatus 100-1. For this reason, when the state of the information processing apparatus 100-1 is a state in which data synchronization can be performed efficiently, by performing data synchronization, resources of the information processing apparatus 100-1 due to data synchronization are reduced. It can be used efficiently.

(Fourth modification)
As a fourth modification of the present embodiment, the information processing apparatus 100-1 may synchronize light field image data generated by imaging with a light field camera using update synchronization and speculative synchronization. . Specifically, the information processing apparatus 100-1 performs update synchronization on the standard image display data of the light field image data, and performs speculative synchronization on data included in the light field image data other than the standard image display data. . For example, a description will be given with reference to FIG. FIG. 10 is a diagram illustrating an example of the update synchronization execution table 12 of the information processing device 100-1 according to the fourth modification example of the first embodiment of the present disclosure.

First, when the light field image data is generated or updated, the storage unit 106 notifies the determination unit 108 of generation or update of each of the data included in the standard image display data and the other light field image data. . Then, the determining unit 108 refers to the update synchronization execution table 12 for each piece of data related to the notification, and determines whether or not the data is subject to update synchronization. For example, as shown in FIG. 10, since the update synchronization flag is “valid” for the standard image display data, the determination unit 108 determines that the data is data subject to update synchronization. For data included in the light field image data other than the standard image display data, the update synchronization flag is “invalid”, and therefore the determination unit 108 determines that the data is not the update synchronization target data.

Next, the update synchronization execution unit 112 synchronizes the standard image display data determined to be update synchronization target data. Further, regarding the data included in the light field image data other than the standard image display data, synchronization is performed by the speculative synchronization execution unit 116 when the conditions for performing the speculative synchronization in the speculative synchronization execution table 20 are satisfied. Done. For example, the condition for performing the speculative synchronization may be access to standard image display data. Note that the conditions for performing the speculative synchronization may be set in advance or may be determined by the determination unit 114.

In this way, the information processing apparatus 100-1 performs update synchronization on the standard image display data of the light field image data, and performs speculative synchronization on data included in the light field image data other than the standard image display data. . Therefore, update synchronization is performed on the standard image display data related to the standard image displayed first, and speculative synchronization is performed on other data used after the standard image is displayed. Even if everything is in a state before being synchronized, the user can view the standard image.

(Fifth modification)
As a fifth modification of the present embodiment, the information processing apparatus 100-1 may synchronize map data using update synchronization and speculative synchronization. Specifically, the information processing apparatus 100-1 performs update synchronization for each of the point data and line data of the map data, and performs speculative synchronization for each of the other data included in the polygon data and the map data. For example, a description will be given with reference to FIG. FIG. 11 is a diagram illustrating an example of the update synchronization execution table 14 of the information processing device 100-1 according to the fifth modification example of the first embodiment of the present disclosure.

First, when the map data is generated or updated, the storage unit 106 notifies the determination unit 108 of generation or update of each of point data, line data, polygon data, and other data included in the map data. Then, the determining unit 108 refers to the update synchronization execution table 14 for each piece of data related to the notification, and determines whether or not the data is subject to update synchronization. For example, as shown in FIG. 11, since the update synchronization flag is “valid” for each of the point data and the line data, the determination unit 108 determines that each of the data is data to be updated and synchronized. . Further, for each of the other data included in the polygon data and the map data, since the update synchronization flag is “invalid”, the determination unit 108 determines that each of the data is not the update synchronization target data.

Next, the update synchronization execution unit 112 synchronizes each of the point data and the line data determined to be update synchronization target data. Each of the other data included in the polygon data and the map data is synchronized by the speculative synchronization execution unit 116 when a condition for performing speculative synchronization is satisfied in the speculative synchronization execution table 20. . For example, the condition for performing the speculative synchronization may be access to point data or line data. The other data may be data having a larger amount of data than other map data such as aerial photographs or altitudes. In addition, a condition for performing the speculative synchronization may be set in advance or may be determined by the determination unit 114.

Thus, the information processing apparatus 100-1 performs update synchronization for each of the point data and line data of the map data, and performs speculative synchronization for each of the other data included in the polygon data and the map data. For this reason, update synchronization is performed for each of point data and line data that are main map information, and speculative synchronization is performed for each of polygon data that is additional map information and other data included in the map data. Thus, even if all of the map data is in a state before being synchronized, the user can grasp the main map information.

(Sixth Modification)
As a sixth modification of the present embodiment, the information processing apparatus 100-1 may perform synchronization of 3D image data using update synchronization and speculative synchronization. Specifically, the information processing apparatus 100-1 performs update synchronization for each of the modeling data of the three-dimensional image data and the low-resolution texture data of the two types of texture data, Speculative synchronization is performed on high-resolution texture data. For example, a description will be given with reference to FIG. FIG. 12 is a diagram illustrating an example of the update synchronization execution table 16 of the information processing device 100-1 according to the sixth modification example of the first embodiment of the present disclosure.

First, when the three-dimensional image data is generated or updated, the storage unit 106 notifies the determination unit 108 of generation or update of the modeling data, the low-resolution texture data, and the high-resolution texture data. Then, the determining unit 108 refers to the update synchronization execution table 16 for each piece of data related to the notification, and determines whether or not the data is subject to update synchronization. For example, as shown in FIG. 12, since the update synchronization flag is “valid” for each of the modeling data and the low-resolution texture data, the determination unit 108 is the data to be updated and synchronized. Is determined. Further, since the update synchronization flag is “invalid” for the high-resolution texture data, the determination unit 108 determines that the data is not the update synchronization target data.

Next, the update synchronization execution unit 112 synchronizes each of the modeling data determined to be the update synchronization target data and the low-resolution texture data. In addition, the high-resolution texture data is synchronized by the speculative synchronization execution unit 116 when a condition for performing speculative synchronization is satisfied in the speculative synchronization execution table 20. For example, the condition for the speculative synchronization to be performed may be access to modeling data or low-resolution texture data. Note that the conditions for performing the speculative synchronization may be set in advance or may be determined by the determination unit 114.

Thus, the information processing apparatus 100-1 performs update synchronization for each of the modeling data of the three-dimensional image data and the low-resolution texture data, and performs speculative synchronization for the high-resolution texture data. For this reason, update synchronization is performed for each of the modeling data and the low-resolution texture data, and speculative synchronization is performed for the high-resolution texture data. This is the state before all of the three-dimensional image data is synchronized. Even so, the user can grasp the shape and approximate surface of the three-dimensional image.

<3. Second Embodiment of the Present Disclosure>
Heretofore, the first embodiment of the present disclosure has been described. Next, a second embodiment of the present disclosure will be described. In the second embodiment of the present disclosure, the information processing apparatus 100-2 synchronizes the data in response to a data synchronization request from the application 104 or the like. In addition, the information processing apparatus 100-2 periodically synchronizes data.

[3-1. Configuration of Information Processing Device According to Second Embodiment of Present Disclosure]
First, the configuration of the information processing apparatus 100-2 according to the second embodiment of the present disclosure will be described with reference to FIG. FIG. 13 is a block diagram illustrating a schematic functional configuration of an information processing device 100-2 according to the second embodiment of the present disclosure. Note that a description of a configuration that is substantially the same as the configuration of the information processing apparatus 100-1 according to the first embodiment of the present disclosure will be omitted.

As illustrated in FIG. 13, the information processing apparatus 100-2 includes an on-demand synchronization execution unit 130 in addition to the operation detection unit 102, the application 104, the storage unit 106, the determination unit 108, the synchronization execution unit 110, and the communication unit 118. And a periodic synchronization execution unit 132. The on-demand synchronization execution unit 130 and the periodic synchronization execution unit 132 are a third synchronization execution unit and a fourth synchronization execution unit in the claims.

The on-demand synchronization execution unit 130 synchronizes the data when the unsynchronized data is accessed. Specifically, when the data synchronization request is notified from the storage unit 106 that recognizes access to unsynchronized data, the on-demand synchronization execution unit 130 receives other information including data related to the data synchronization request. A synchronization request for the processing device is generated. Then, the on-demand synchronization execution unit 130 causes the communication unit 118 to transmit the generated synchronization request to other information processing apparatuses to be synchronized.

The periodic synchronization execution unit 132 periodically synchronizes data. Specifically, the periodic synchronization execution unit 132 determines the synchronization target data based on the synchronization time interval for each type of data stored in the storage unit 106 and the last synchronization time, and is determined as the synchronization target. Data synchronization. More specifically, when the periodic synchronization processing execution time comes, the periodic synchronization execution unit 132 acquires the synchronization time interval and the last synchronization time for each type of data stored in the storage unit 106. Next, for each data type, the periodic synchronization execution unit 132 calculates the elapsed time from the last synchronization from the acquired last synchronization time and the current time, and sets the calculated synchronization time interval as the acquired elapsed time. Judge whether it exceeds. Then, the periodic synchronization execution unit 132 synchronizes the data for each of the types of data determined that the elapsed time exceeds the synchronization time interval through communication with the synchronization target device having data corresponding to the data type. I do. The data synchronization process is substantially the same as the process of the speculative synchronization execution unit 116 according to the first embodiment of the present disclosure, and thus the description thereof is omitted.

When the storage unit 106 accesses unsynchronized data, the storage unit 106 notifies the on-demand synchronization execution unit 130 of the data synchronization request. Specifically, the storage unit 106 stores the data synchronization state for each of the stored data. When the application 104 accesses unsynchronized data, the storage unit 106 stores the data synchronization state. To determine whether it is unsynchronized. When the storage unit 106 determines that the data is not synchronized, the storage unit 106 notifies the on-demand synchronization execution unit 130 of a synchronization request for the data.

Further, the storage unit 106 stores the synchronization time interval and the last synchronization time for each type of data constituting the file system data. For example, the storage unit 106 may store the synchronization time interval and the last synchronization time for each of the directory structure, file attributes, and file body. In the above description, the example in which the synchronization time interval and the last synchronization time are stored for each type of data has been described. However, the storage unit 106 stores the synchronization time interval and the last synchronization time for each data, and periodically The synchronization execution unit 132 may perform periodic synchronization processing for each data. For this reason, it becomes possible to synchronize according to the feature for every data by subdividing the object of processing of periodic synchronization.

[3-2. Processing of Information Processing Device in Second Embodiment of Present Disclosure]
Next, processing of the information processing apparatus 100-2 according to the second embodiment of the present disclosure will be described. Since the information processing apparatus 100-2 performs on-demand synchronization and periodic synchronization processing, each of the on-demand synchronization and periodic synchronization processing will be described.

First, on-demand synchronization processing of the information processing apparatus 100-2 will be described with reference to FIG. FIG. 14 is a flowchart conceptually showing an on-demand synchronization process of the information processing device 100-2 according to the second embodiment of the present disclosure. Note that a description overlapping the description of the configuration of the information processing apparatus 100-2 is omitted.

First, the information processing apparatus 100-2 waits until data access is performed (step S502). Specifically, when access is made to data stored in the storage unit 106 from the application 104 or the like, the storage unit 106 recognizes the data access.

When data access is performed in step S502, the storage unit 106 determines whether the accessed data is not synchronized (step S504). Specifically, the storage unit 106 determines whether the accessed data is unsynchronized based on the synchronization state of the data stored in the storage unit 106.

If it is determined in step S504 that the accessed data is not synchronized, the on-demand synchronization execution unit 130 confirms whether communication with another information processing apparatus having the accessed data is possible (step S506). ). Specifically, when it is determined that the accessed data is not synchronized, the storage unit 106 notifies the on-demand synchronization execution unit 130 of the data synchronization request. Next, when the synchronization request is notified, the on-demand synchronization execution unit 130 performs the other information processing based on the identification information of the other information processing apparatus having the unsynchronized data included in the synchronization request. An instruction to confirm whether communication with the apparatus is possible is notified to the communication unit 118. Then, the communication unit 118 confirms whether communication is possible based on the notification, and returns a confirmation result to the on-demand synchronization execution unit 130.

If it is confirmed in step S506 that communication with another information processing apparatus having the accessed data is possible, the on-demand synchronization execution unit 130 synchronizes the accessed data (step S508).

Next, periodic synchronization processing of the information processing apparatus 100-2 will be described with reference to FIG. FIG. 15 is a flowchart conceptually showing a periodic synchronization process of the information processing apparatus 100-2 according to the second embodiment of the present disclosure. Note that a description overlapping the description of the configuration of the information processing apparatus 100-2 is omitted.

First, the periodic synchronization execution unit 132 waits until the execution time of the periodic synchronization comes (step S602).

In step S602, when the execution time of the periodic synchronization comes, the periodic synchronization execution unit 132 determines whether there is data that has reached the synchronization time (step S604). Specifically, the periodic synchronization execution unit 132 sets the data for which the synchronization time has arrived for each data type based on the synchronization time interval and the last synchronization time for each data type stored in the storage unit 106. It is determined whether or not there is a kind of.

When it is determined in step S604 that there is data that has reached the synchronization time, the periodic synchronization execution unit 132 determines whether or not there is a synchronization target device that can communicate (step S606). Specifically, the periodic synchronization execution unit 132 acquires the data synchronization target device stored in the storage unit 106 for the data that is the type of data determined as the synchronization target in step S604, and the communication unit 118. Is notified of a confirmation instruction as to whether or not there is a communicable target device. Then, the communication unit 118 confirms a synchronization target device that can communicate based on the notification, and returns a confirmation result to the speculative synchronization execution unit 116.

If it is determined in step S606 that there is a communicable synchronization target device, the periodic synchronization execution unit 132 synchronizes data whose synchronization time has arrived (step S608). Note that the data synchronization processing is substantially the same as the processing in step S412 of the speculative synchronization execution unit 116 according to the first embodiment of the present disclosure, and thus description thereof is omitted.

As described above, according to the second embodiment of the present disclosure, the information processing apparatus 100-2 synchronizes the data when the unsynchronized data is accessed. In addition, the information processing apparatus 100-2 periodically synchronizes data. For this reason, it is possible to suppress the amount of communication related to data synchronization by performing data synchronization when a synchronization request is generated. In addition, since the data synchronization is performed regardless of the generation of the synchronization request, it is possible to suppress the occurrence of the waiting time related to the data synchronization.

[3-3. Modification of Second Embodiment of Present Disclosure]
Heretofore, the second embodiment of the present disclosure has been described. In addition, this embodiment is not limited to the above-mentioned example. Below, the modification of this embodiment is demonstrated.

As a modification of the present embodiment, the synchronization execution unit 110 may perform synchronization of data related to the synchronization request by a progressive download method. Specifically, the synchronization execution unit 110 refers to the transmission method for each type of data stored in the storage unit 106 and determines the transmission method of the received synchronization target data. When it is determined that the transmission method is progressive download, the synchronization execution unit 110 provides the synchronization target data to the application 104 while storing the data to be synchronized in the storage unit 106. More specifically, the storage unit 106 stores a transmission method for each data type. In addition to the progressive download method, for example, there may be a complete download method that performs only download. Then, when the data corresponding to the synchronization request received from the other information processing apparatus is passed from the communication unit 118, the synchronization execution unit 110 refers to the storage unit 106 and confirms the transmission method of the data. Next, when it is confirmed that the transmission method of the data is progressive download, the synchronization execution unit 110 provides the data to the application 104 while storing the data in the storage unit 106.

Thus, when the data transmission method related to the synchronization request is the progressive download method, the synchronization execution unit 110 provides the data to the application 104 while storing the data in the storage unit 106. For this reason, it is possible to reduce the waiting time related to data synchronization by being provided to the application 104 before the data download related to the synchronization request is completed.

<5. Conclusion>
According to the first embodiment of the present disclosure, the synchronization of data is performed before the timing at which the data is used, so that it is possible to suppress the occurrence of a waiting time related to the synchronization of data. Further, according to the second embodiment of the present disclosure, data synchronization is performed when a synchronization request is generated, so that it is possible to suppress a communication amount related to data synchronization. In addition, since the data synchronization is performed regardless of the generation of the synchronization request, it is possible to suppress the occurrence of the waiting time related to the data synchronization.

For example, in the above embodiment, update synchronization, speculative synchronization, or periodic synchronization is performed based on information such as the update synchronization execution table 10, the speculative synchronization execution table 20, or the synchronization time interval stored in the storage unit 106. Although the synchronization is performed, the present technology is not limited to such an example. For example, when the synchronization target data is data generated or updated by another information processing apparatus, the above information may be specified by another information processing apparatus that has transmitted the synchronization target data. For example, when the communication unit 118 receives synchronization target data from another information processing apparatus, the communication unit 118 can also receive a notification that the synchronization target data is to be updated and synchronized.
