[First Embodiment]
FIG. 1 is a block diagram illustrating a configuration of an image data management system according to the present embodiment. As shown in FIG. 1, the image data management system according to this embodiment includes a first terminal 10, a second terminal 12, a data server 14, a printer 16, and a projector 18. These are connected to each other via the network 20.

  FIG. 2 is a block diagram illustrating the configuration of the first terminal 10, and FIG. 3 is a block diagram illustrating the configuration of the data server 14. FIG. 4 is a flowchart illustrating the image data registration process according to the present embodiment.

  An image data registration process for registering additional information corresponding to image data in the data server 14 from the first terminal 10 will be described with reference to FIGS. As can be seen from these figures, in the image data registration process, first, the image data acquisition unit 100 of the first terminal 10 acquires image data (step S10). The image data acquisition unit 100 acquires the image data from, for example, a digital camera, a memory card, a CD-ROM, a flexible disk, a hard disk, the Internet, or the like.

  Next, the unique information calculation unit 102 calculates unique information that is unique identification information based on the image data (step S12). That is, when the same image data is used, the same value is obtained, and when different image data is used, the unique information is calculated using a technique that obtains a different value. For example, in the present embodiment, this unique information is calculated using a hash function.

  Next, the additional information acquisition unit 104 acquires additional information to be added to the image data (step S14). For example, the user generates character information related to the image data, key information for identifying a plurality of image data as a group, voice information, music information, and the like, and inputs them to the first terminal 10. The acquisition unit 104 acquires these pieces of information as additional information. This additional information is information also called metadata. In the present embodiment, the additional information may be a command for executing printing by a printer or a command for executing projection by a projector.

  Next, the communication unit 106 transmits the unique information and the additional information to the data server 14 via the network 20 (step S16). And the communication part 200 of the data server 14 receives these specific information and additional information (step S18).

  Next, the storage unit 202 associates the received unique information with the additional information, stores them in the database 204, and registers them (step S20). In this registration, the image data itself does not have to be registered in this embodiment. However, the image data may also be registered. As the database 204, a general relational database can be used.

  FIG. 5 is a diagram showing a configuration of the additional information storage table TB10 in the database 204 according to the present embodiment, in which these unique information and additional information are stored in association with each other. As shown in FIG. 5, the additional information table TB10 includes unique information TM10 and additional information TM12 as data items. The received unique information is stored in the additional information TM10, and the received additional information is stored in the additional information TM12.

  Next, an image data inquiry process in which the second terminal 12 acquires additional information corresponding to the image data from the data server 14 and displays it will be described. FIG. 6 is a block diagram illustrating the configuration of the second terminal 12. FIG. 7 is a flowchart illustrating the image data inquiry process according to the present embodiment.

  As can be seen from these figures, in the image data inquiry process, first, the image data acquisition unit 300 acquires image data (step S50). This image data is the same data as the image data acquired in step S10 described above. Various methods for the image data acquisition unit 300 to acquire image data are conceivable. In the present embodiment, for example, the image data acquisition unit 300 acquires the image data from the first terminal 10 via the network 20. Alternatively, the image data may be acquired from a digital camera, a memory card, a CD-ROM, a flexible disk, or the Internet.

  Next, the unique information calculation unit 302 calculates unique unique information based on the image data (step S52). The unique information calculation unit 302 calculates unique information by the same method as the unique information calculation unit 102 described above.

  Next, the communication unit 304 requests additional information from the data server 14 based on the unique information (step S54). Specifically, the communication unit 304 transmits, to the data server 14, an additional information transmission request for requesting transmission of specific information and additional information corresponding to the specific information via the network 20. And the communication part 200 of the data server 14 shown in FIG. 3 receives this additional information transmission request (step S56).

  Next, the reading unit 206 of the data server 14 searches the database 204 based on the received unique information, and reads additional information corresponding to the unique information (step S58). Specifically, as shown in FIG. 5, a table that matches the received unique information is searched from the unique information TM10 in the additional information storage table TB10 in the database 204, and the additional information TM12 of the matched table is stored. Read the stored additional information.

  Next, as illustrated in FIGS. 3 and 7, the communication unit 200 of the data server 14 transmits the read additional information to the second terminal 12 via the network 20 (step S60). Specifically, the additional information is added to the unique information and transmitted to the second terminal 12.

  Next, as shown in FIGS. 6 and 7, the communication unit 304 of the second terminal 12 receives the additional information (step S62). Subsequently, the combining unit 306 combines the received additional information with the image data acquired by the image data acquisition unit 300 (step S64). Then, the display unit 308 displays the information obtained by combining on the screen (step S66). For example, when the additional information is text information “photo taken at camping”, the display unit 308 displays image data, and “photo taken at camping” is displayed below the image data. indicate.

  Next, image data output processing in which output processing is performed on the printer 16 and the projector 18 based on additional information attached to image data will be described. FIG. 8 is a block diagram illustrating the configuration of the printer 16 and the projector 18. FIG. 9 is a flowchart illustrating image data output processing according to the present embodiment. Here, a case where the printer 16 performs image data output processing will be described as an example.

  As can be seen from these figures, in the image data output process, first, the image data acquisition unit 400 acquires image data (step S100). This image data is the same data as the image data acquired in step S10. Various methods for the image data acquisition unit 400 to acquire image data are conceivable. In the present embodiment, for example, the image data acquisition unit 400 acquires the image data from the first terminal 10 via the network 20. Alternatively, the image data may be acquired from a digital camera, a memory card, a CD-ROM, a flexible disk, or the Internet.

  Next, the unique information calculation unit 402 calculates unique unique information based on the image data (step S102). The unique information calculation unit 402 calculates unique information by the same method as the unique information calculation unit 102 described above.

  Next, the communication unit 404 requests additional information from the data server 14 based on the unique information (step S104). Specifically, the communication unit 404 transmits the unique information and the additional information transmission request to the data server 14 via the network 20. And the communication part 200 of the data server 14 shown in FIG. 3 receives this additional information transmission request (step S106).

  Next, the reading unit 206 of the data server 14 searches the database 204 based on the received unique information, and reads additional information corresponding to the unique information (step S108). Specifically, as shown in FIG. 5, a table that matches the received unique information is searched from the unique information TM10 in the additional information storage table TB10, and stored in the additional information TM12 of the matched table. Read additional information.

  Next, as illustrated in FIGS. 3 and 8, the communication unit 200 of the data server 14 transmits the read additional information to the printer 16 via the network 20 (step S110). Specifically, the additional information is added to the unique information and transmitted to the printer 16.

  Next, as shown in FIGS. 8 and 9, the communication unit 404 of the printer 16 receives the additional information (step S112). Subsequently, the additional information analysis unit 406 analyzes the received additional information and determines whether a command for the printer 16 is included (step S114). That is, it is determined whether specific information (in this example, a command to print) is included in the additional information.

  If the command to print is not included in the additional information (step S114: No), this process ends without doing anything. On the other hand, when the command to print is included in the additional information (step S114: Yes), the process execution unit 408 executes printing (step S116). At this time, if the additional information includes character information, the character information is printed together with the image data.

  After the printing is completed, the communication unit 404 of the printer 16 transmits an update request for deleting the corresponding additional information to the data server 14 via the network 20 so that another printer does not perform the same process. (Step S118). Specifically, the unique information and the update request are transmitted from the printer 16 to the data server 14. The communication unit 200 of the data server 14 illustrated in FIG. 3 receives the unique information and the update request (Step S120).

  Next, the update unit 208 of the data server 14 updates the additional information in the database 204 based on this update request (step S122). Specifically, the additional information storage table TB10 is searched based on the unique information received together with the update request, and a table that matches the received unique information is found from the unique information TM10 in the additional information storage table TB10. Then, the additional information stored in the additional information TM12 in the table in which the unique information TM10 matches is updated. In this example, the additional information of the command for printing with the printer is deleted.

  When image data is projected by the projector 18, as shown in FIG. 5, a command for projecting by the projector is included in the additional information.

  As described above, according to the image data management system according to the present embodiment, image data and additional information attached to the image data can be managed separately, and the logical association between the two can be maintained. . In other words, conventionally, the additional information accompanying the image data has a unique data format, so that the additional information can only be handled by software corresponding to the specific data format. For example, since the image data and the additional information are independent, the general software, the general printer 16 and the projector 18 can handle the image data. In addition, since the association between the image data and the additional information is held by the data server 14 based on the unique information generated from the image data, the second terminal 12, the printer 16, and the projector 18 can easily associate them. Can do.

  Moreover, according to the image data management system according to the present embodiment, for example, even when a certain user changes the additional information at the terminal, the change is reflected in the database 204 of the data server 14, so that the change is made at another terminal. Later additional information can be acquired. For this reason, the additional information can be managed centrally.

[Second Embodiment]
In the second embodiment, the above-described first embodiment is modified so that the additional information of the image data can be centrally managed even when the user modifies the image data at another terminal. Hereinafter, the present embodiment will be described on the assumption that the user corrects image data using the second terminal 12.

  FIG. 10 is a flowchart illustrating the content of the image data correction process executed by the second terminal 12. As can be seen from FIG. 10 and FIG. 6 described above, the image data acquisition unit 300 of the second terminal 12 acquires image data before correction from a hard disk or the like (step S146). Subsequently, the unique information calculation unit 302 calculates unique information based on the image data before correction (step S148). The method for calculating the unique information is the same as that in the first embodiment described above.

  Next, the image data acquisition unit 300 acquires image data corrected by the user from a hard disk or the like (step S150). For example, it is assumed that the user adds retouching (correction of brightness, color, etc.) to the image data.

  Next, the unique information calculation unit 302 calculates the corrected unique information based on the corrected image data (step S152). The method for calculating the unique information is the same as that in the first embodiment described above.

  Next, the communication unit 304 transmits the unique information before correction of the image data and the unique information after correction to the data server 14 via the network 20 (step S154). The transmitted unique information before modification and unique information after modification are received by the communication unit 200 of the data server 14 of the data server 14 shown in FIG. 3 (step S156).

  Next, the storage unit 202 of the data server 14 stores and registers the received unique information before modification and unique information after modification in the database 204 (step S158).

  FIG. 11 is a diagram showing an example of the configuration of the post-correction specific information table TB20 in the database 204 in which the specific information before correction and the specific information after correction are stored. As shown in FIG. 11, the post-correction specific information table TB20 includes specific information TM20 and post-correction specific information TM22 as data items.

  The received unique information before modification is stored in the unique information TM20, and the received unique information after modification is stored in the modified unique information TM22. That is, the post-correction specific information table TB20 associates the pre-correction specific information with the post-correction specific information.

  Next, image data inquiry processing executed by the image data management system according to the present embodiment will be described. FIG. 12 is a flowchart illustrating image data inquiry processing according to the present embodiment. Here, a case where the second terminal 12 acquires additional information based on the corrected image data and displays it with the image data will be described as an example.

  As can be seen from this figure, in the image data inquiry process, first, the image data acquisition unit 300 of the second terminal 12 acquires image data (step S200). In this example, the image data acquisition unit 300 acquires the corrected image data from, for example, the hard disk of the second terminal 12. However, since this image data is simply image data, it cannot be identified whether the image data has been modified.

  Next, the unique information calculation unit 302 calculates unique unique information based on the image data (step S202). The unique information calculation unit 302 calculates unique information by the same method as in the first embodiment described above.

  Next, the communication unit 304 requests additional information from the data server 14 based on the unique information (step S204). Specifically, the communication unit 304 transmits the unique information and the additional information transmission request to the data server 14 via the network 20. Then, the communication unit 200 of the data server 14 illustrated in FIG. 3 receives the unique information and the additional information transmission request (step S206).

  Next, the reading unit 206 of the data server 14 searches the database 204 based on the received unique information, and reads additional information corresponding to the unique information (step S208). Specifically, as shown in FIG. 5, a table that matches the received unique information is searched from the unique information TM10 in the additional information storage table TB10 in the database 204, and the additional information TM12 of the matched table is stored. Read the stored additional information.

  Next, the reading unit 206 of the database 204 determines whether additional information has been found from the additional information storage table TB10 (step S210). If additional information is found (step S210: Yes), this additional information is transmitted to the second terminal 12 via the network 20 (step S212).

  On the other hand, when it is determined in step S210 that additional information has not been found from the additional information storage table TB10 (step S210: No), the reading unit 206 searches the post-correction specific information table TB20, and before the correction. Is acquired (step S214). That is, since the additional information was not found from the additional information storage table TB10 in the received unique information, it is considered that the received unique information was generated based on the corrected image data. For this reason, in the present embodiment, it is determined that the received unique information is the modified unique information, and the modified unique information TM22 in the modified unique information table TB20 is searched. Then, the unique information TM20 of the table storing the modified unique information TM22 that matches the received unique information is acquired. The unique information stored in the unique information TM20 is unique information before the image data is corrected.

  Next, the reading unit 206 of the data server 14 illustrated in FIG. 3 searches the additional information storage table TB10 based on the unique information before correction, and the additional information held corresponding to the specific information before correction. Is acquired (step S216). And the communication part 200 transmits this additional information to the 2nd terminal 12 via the network 20 (step S218).

  The processes (steps S62 to S66) of the second terminal 12 after receiving the additional information transmitted in step S212 or step S218 shown in FIG. 12 are the same as those in the first embodiment described above.

  In the present embodiment as well, the image data output process can be executed as in the first embodiment. In this case, as in the case of the image data inquiry processing described with reference to FIG. 12, the data server 14 searches the additional information storage table TB10 based on the received unique information, and if additional information is not found. Then, it is determined that the received unique information is corrected, and the corrected unique information table TB20 is searched. Then, the additional information storage table TB10 is searched again based on the uncorrected unique information stored in the corrected unique information table TB20 to find additional information corresponding to the image data.

  Since points other than those described above are the same as in the first embodiment, detailed description thereof is omitted here.

  As described above, according to the image data management system according to the present embodiment, even when each user modifies image data, the data server 14 centrally manages the additional information corresponding to the image data. Can do.

  That is, when the image data is modified, the unique information generated from the image data is different from the unique information generated from the image data before the correction. Therefore, in the present embodiment, the correspondence between the unique information before modification and the unique information after modification is stored in the modified unique information table TB20 of the data server 14. Therefore, even when correction is made to the image data, the unique information before the correction can be acquired based on the unique information generated based on the corrected image data, and the additional information can be obtained based on this. Can be obtained.

  According to the image data management system in the embodiment described above, for example, the following can be realized.

(1) When a processing device such as a printer or a projector outputs image data, the additional information is acquired from the data server 14, and the additional information is output together with the image data.

(2) By storing image data in the data server 14 by a plurality of users, the image data and its additional information can be managed centrally.

(3) An online album of image data can be realized by a plurality of users writing memos and impressions with respect to image data and links to other image data as additional information.

(4) Only a part of a lot of image data is stored in a portable device such as a photo viewer, and the portable device is carried. If necessary, this portable device is connected to the data server 14 to acquire additional information corresponding to the image data.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation is possible. For example, the first terminal 10 and the second terminal 12 described above are examples of an information processing terminal, and can be realized by various terminals such as a desktop personal computer and a notebook personal computer.

  Similarly, the first terminal 10, the second terminal 12, the printer 16, and the projector 18 are examples of processing devices, and may be other types of devices that process image data.

  In addition, each process described in the above embodiment can be realized by a program that is software instead of hardware. In this case, the program can be recorded on a recording medium such as a flexible disk, a CD-ROM (Compact Disc-Read Only Memory), a ROM, or a memory card, and distributed in the form of the recording medium. In this case, the above-described embodiment is realized by causing the first terminal 10, the second terminal 12, the data server 14, the printer 16, and the projector 18 to read and execute the recording medium on which the program is recorded. Can do.

  The first terminal 10, the second terminal 12, the data server 14, the printer 16, and the projector 18 may include other programs such as an operating system and another application program. In this case, other programs included in the first terminal 10, the second terminal 12, the data server 14, the printer 16, and the projector 18 are utilized, and the first terminal 10, the second terminal 12, and the data server 14 are used as recording media. A command for calling a program that realizes processing equivalent to that in the above-described embodiment may be recorded from among programs provided in the printer 16 and the projector 18.
