Description

  The present invention relates to a content management apparatus for managing content, and more particularly to management of personal information and the like added to content.

In recent years, services that publish content such as photographic images and moving images created and photographed by users on the Web have become widespread. In addition, for improvement of services, new services that are linked with other services using additional information accompanying content are also being studied.
For example, by linking with other services that display position information on a map, it is possible to realize a service that publishes on the web a photographic image with a shooting location added as additional information. The viewer of the photographic image can check the shooting location on the map.

As additional information, in addition to the above-mentioned information, in addition to image data and audio data, a shooting time, a shooting location, a photographer name, a photographer address, a photographer e-mail address, a shooting device manufacturer name, and a shooting device model are added to the content. A name, information about a subject, comment information by a user, a search keyword, and the like can be considered.
As in the above example, it is possible to provide convenient services by utilizing additional information. However, additional information may include user personal information such as the photographer's name and photographer's address. Therefore, appropriate management is required.

Regarding appropriate management of additional information, Patent Document 1 discloses a digital camera that deletes and transfers additional information according to a transfer destination when a captured image is transferred via a network.
Further, Patent Document 2 discloses a content data processing apparatus that deletes and transmits privacy information or position information included in additional information when transmitting an image file.

However, according to the disclosed technique, when a plurality of contents are collectively transmitted to a web server, even if specific additional information of a certain content is deleted, the deleted additional information is deleted from the additional information of other contents. There is a problem that it can be identified by analogy.
For example, as additional information, when the contents 1 and 2 of a photograph to which a photographing location and a photographing time are added are collectively transmitted to the server, even if the photographing location of the content 1 is deleted, the photographing location and the content of the content 2 are deleted. The shooting location of the content 1 may be inferred from the shooting interval between the content 1 and the content 2 (for example, 1 minute).

Further, if all the additional information is deleted when a plurality of contents are transmitted at once, the above-mentioned web service cannot be linked with other services, and the service cannot be improved.
In view of the above problems, the present invention provides a content management apparatus capable of preventing additional information to be concealed from additional information added to content transmitted in a batch when a plurality of content are transmitted in batch.

The user interface unit 201 transmits the transmission request to the content output control unit 204.

The content output control unit 204 determines whether or not the related additional information deletion processing in the related additional information deletion unit 207 is necessary (step S2).
When the related additional information deletion process is necessary (step S2: YES), the additional information deletion unit 206 selects one content to be processed (step S3). Here, it is assumed that the additional information deletion unit 206 selects the contents stored in the content storage unit 202 one by one every time step S3 is executed.

Next, the additional information deletion unit 206 sets the parameter in the additional information for the content to be transmitted selected in step S3 based on the output permission list, the output prohibition list, and the out-of-list output setting value stored in the user setting storage unit 203. It is determined whether or not deletion is necessary (step S4). This step will be described later.
Next, the related additional information deletion unit 207 determines whether or not the related additional information needs to be deleted for the content selected in step S3 based on the related additional information list stored in the user setting storage unit 203 (step S5). This step will be described later.

Then, it is determined whether or not steps S3 to S5 have been executed for all the contents to be transmitted (step S6), and if not executed (step S6: NO), step S3 is executed.
If it has been executed (step S6: YES), the process proceeds to the setting process by the user (step S7).

  In the setting process by the user, the user interface unit 201 presents an output permission list, an output prohibition list, an out-list output setting value, and a related additional information list stored in the user setting storage unit 203 to the user. Furthermore, the user interface unit 201 causes the user operation accepting unit 209 to add / modify the output permission list, the output prohibition list, the out-list output setting value, and the related additional information list. This step will be described later.

Then, the content output control unit 204 instructs the content output unit 208 to perform content transmission processing to the server apparatus 101 after removing the additional information marked for deletion and the related additional information from all the content to be transmitted (step S100). S8).
Then, the content output unit 208 transmits the content to be transmitted from which the additional information has been deleted to the server apparatus 101 as necessary, thereby completing the content transmission process.

If it is determined in step S2 that the related additional information deletion process is unnecessary (step S2: NO), steps S9 to S13 are executed.
Here, the processing from step S9 to S12 is the above-described step S3 to S7 except for the related additional information deletion processing (step S5).
That is, step S9 is the same process as step S3, step S10 is the same process as step S4, step S11 is the same process as step S6, and step S12 is the same as step S7. Since it is a process, description of step S9-S12 is abbreviate | omitted.

After step S12, the content output control unit 204 instructs the content output unit 208 to perform content transmission processing to the server apparatus 101 after excluding additional information marked for deletion from all content to be transmitted (step S12). Step S13).
Then, the content output unit 208 transmits the content to be transmitted from which the additional information has been deleted to the server apparatus 101 as necessary, and completes the content transmission process.

The processing of each step in FIG. 7 has been described above.
3.3. Additional Information Deletion Processing Additional information deletion processing corresponding to steps S4 and S10 in FIG. 7 will be described.
In the following description, when the shooting location is described using a specific example, the setting value of the shooting location parameter of each image file and the shooting location parameters registered in the output permission list and the output prohibition list are related. The positional relationship with the set value will be described as being in the positional relationship shown in FIG.

FIG. 8 is a diagram illustrating a flow of additional information deletion processing.
The additional information analysis unit 205 analyzes the additional information of the target content and extracts each parameter (step S21).
For example, in the case of the file F2, the shooting time parameter “January 1, 2008 0:10:00”, the shooting location parameter “point b”, the photographer name parameter “Taro Yamada”, and the comment information parameter “home” and Extract “Hanako Yamada”.

Next, the additional information deletion unit 206 selects one parameter from the parameters of the additional information extracted in step S21 regarding the target content in step S3 (step S22).
For example, the shooting time parameter is selected from the shooting time parameter, shooting location parameter, photographer name parameter, and comment information parameter in the additional information. Thereafter, each time step S22 is executed, one parameter is selected from the unselected parameters.

It is determined whether or not the selected parameter and its set value set are included in the output prohibition list (step S23), and if included (step S23: YES), deletion marking is performed on the corresponding parameter (step S23: YES). Step S26).
For example, since the set of the shooting location parameter “point b” in the file F2 matches the output prohibition information D2 in the output prohibition list, the shooting location parameter in the file F2 is marked for deletion. As described above with reference to FIG. 11, “point b” is included in “region X”.

If it is determined in step S23 that the file parameters and setting values are not included in the output prohibition list (step S23: NO), it is determined whether or not the file parameters and setting values are included in the output permission list (step S23). Step S24).
For example, when the shooting time parameter of the file F2 is processed using the output permission list, the shooting time parameter “January 1, 2008 0:10:00” of the file F2 is output permission information E1 of the output permission list. Therefore, it is determined that it is not necessary to delete the shooting time parameter of the file F2.

If it is determined in step S24 that the file parameters and setting values are not included in the output permission list (step S24: NO), it is determined whether the file parameters and setting values can be output based on the out-of-list output setting values (step S24). S25).
In step S25, if the out-list output set value is set to prohibit output (step S25: output prohibit), the process proceeds to step S26 described above, and if the out-list output set value is set to permit output (step S25: Output permission), the process proceeds to step S27.

  For example, the comment information parameter “Mt. Fuji”, which is additional information of the file F4, is not registered in either the output permission list or the output prohibition list. In this case, if the output permission is set as the out-of-list output setting value, it is determined that the comment information parameter “Mount Fuji” need not be deleted. If the output prohibition is set, the comment information parameter “ Mt. Fuji is determined to require deletion and is marked for deletion.

  Next, if it is determined in step S24 that the file parameters and setting values are included in the output permission list (step S24: YES), and if the out-list output setting value is output permission setting in step S25 (step S25). : Output permission), it is determined whether or not all the parameters included in the additional information of the content to be processed have been selected (step S27). If all the parameters have been selected (step S27: YES), the process ends.

If all parameters have not been selected (step S27: NO), the process proceeds to step S22.
The processing of each step in FIG. 8 has been described above.
When the out-list output setting value is set to output prohibition based on FIGS. 3 to 6, when the additional information deletion process shown in FIG. 8 is performed, the parameters are deleted as follows. Deletion marking is performed.

The photographer name parameter “Taro Yamada” is deleted from the file F1.
Also, the shooting location parameter “point b”, the photographer name parameter “Taro Yamada”, the comment information parameter “home”, and the comment information parameter “Hanako Yamada” are deleted from the file F2.
No additional information is deleted from the file F3.

The shooting location parameter “point d”, the comment information parameter “Mt. Fuji”, and the comment information parameter “Hanako Yamada” are deleted from the file F4.
3.4. Related Additional Information Deletion Process Next, the related additional information deletion process shown in step S5 of FIG. 7 will be described.
FIG. 9 is a diagram illustrating a flow of related additional information deletion processing.

First, the additional information analysis unit 205 selects one parameter from the additional information of the output target content stored in the content storage unit 202 (step S31).
The selected parameter is called P1.
For example, the additional information analysis unit 205 selects the shooting location parameter as P1 from the additional information of the file F2 that is the output target content.

Then, the related additional information deletion unit 207 determines whether or not P1 is marked for deletion (step S32), and when it is not marked for deletion (step S32: NO), the process proceeds to step S31.
When deletion marking is performed (step S32: YES), the related additional information deletion unit 207 selects one related condition from the related additional information list and extracts parameters (step S33).

Let P2 be the extracted parameter.
For example, the related additional information deletion unit 207 selects the shooting location parameter as P2 from the related condition R1 in the related additional information list.
Next, the related additional information deletion unit 207 selects content other than the content processed in step S31 from the output content (step S34).

For example, when the content processed in step S31 is the file F2, the related additional information deletion unit 207 selects the file F1 among the files F1, F3, and F4 as other content.
Next, the related additional information deletion unit 207 selects one parameter from the additional information of the other content selected in step S34 (step S35).

The extracted parameter is P3.
For example, when the content selected in step S34 is the file F1, the related additional information deletion unit 207 selects the shooting location parameter as P3 from the additional information of the file F1.
Then, the related additional information deletion unit 207 determines whether P1 and P2 match (step S36).

For example, when P1 is a shooting location parameter of the file F2 and P2 is a shooting location parameter of the related condition R1 in the related additional information list, the related additional information deletion unit 207 indicates that both P1 and P2 are shooting location parameters. , It is determined that they match.
Next, the related additional information deletion unit 207 determines whether or not P3 satisfies the related determination condition related to P2 (step S37).

  For example, as shown in FIG. 11, the distance between the shooting location parameter “point a” in the file F1 and the shooting location parameter “point b” in the file F2 is 500 meters. Also, the time interval between the shooting time parameter “January 1, 2008 0:00:00” of the file F1 and the shooting time parameter “January 1, 2008 0:00:00” of the file F2 is 10 Minutes.

Therefore, the shooting location parameter (P3) which is the additional information of the file F1 is related to the related determination condition “P2 is the distance from the shooting location of other content is 1000 meters or less and the shooting interval with other content is 60 minutes or less, Satisfy the setting value of the shooting location parameter that satisfies.
Therefore, in the above case, it is determined that P3 satisfies the relation determination condition related to P2.

As described above, in the determination in step S37, the related additional information deleting unit 207 does not determine using only the shooting location parameter that is a parameter of the related additional information list, but describes it in the related determination condition. The shooting time parameter is also used for the determination.
In step S37, when it is determined that the relation determination condition is satisfied (step S37: YES), the related additional information deletion unit 207 performs deletion marking on P3 which is the related additional information of P1 (step S38), and the related determination condition is set. If it is not determined that the condition is satisfied, the process proceeds to step S39.

Next, the related additional information deletion unit 207 determines whether or not all parameters included in the additional information have been selected for the other content selected in step S34 (step S39).
If all the parameters included in the additional information are not selected in step S39 (step S39: NO), the process proceeds to step S35.

For example, in step S35, an unselected shooting time parameter is selected from the additional information of the file F1.
If it is determined in step S39 that all the parameters included in the additional information have been selected (step S39: YES), the related additional information deletion unit 207 determines whether all other content has been selected (step S40). .

When it is determined in step S40 that all other contents have not been selected (step S40: NO), the process proceeds to step S34.
For example, in step S34, the file F3 is selected as another content.
When it is determined in step S40 that all other contents have been selected (step S40: YES), the related additional information deletion unit 207 determines whether or not all the related conditions in the related additional information list have been selected (step S40). S41).

When all the related conditions are not selected in step S41 (step S41: NO), the process proceeds to step S33, and the next related condition is selected.
For example, in step S33, the related condition R2 related to the photographer name parameter in the related additional information list is selected.
When all the related conditions are selected in step S41 (step S41: YES), the related additional information deletion unit 207 determines whether or not all the parameters of the additional information of the processing target content are selected (step S42). If it is determined that all the parameters of the additional information of the target content have been selected (step S42: YES), the process ends.

If it is determined in step S42 that all the parameters of the additional information of the processing target content have not been selected (step S42: NO), the process proceeds to step S31.
For example, at this time, in step S31, an unselected shooting location parameter is selected from the additional information of the processing target content.
Next, as a specific example, the related additional information deletion process using the related additional information list shown in FIG. 6 will be described with reference to FIG.

It is assumed that the shooting location of each image file has the positional relationship shown in FIG.
First, a shooting location parameter is selected as P1 (corresponding to step S31).
Next, it is determined whether or not the shooting location parameter P1 is marked for deletion (step S81 (corresponding to step S32 in FIG. 9)).

In the following specific example, it is assumed that the shooting location parameter “point b” of the file F2, which is the target content, is marked for deletion in step S4 of FIG.
When deletion marking is not performed on P1 (step S81: NO), the related additional information deletion unit 207 determines that deletion marking is unnecessary even for the reference content (step S85).

When deletion marking is performed on P1 (step S81: YES), the related additional information deletion unit 207 determines whether the distance between the shooting location of the target content and the shooting location of the reference content is 1000 meters or less ( Step S82).
In the present embodiment, if the distance exceeds 1000 meters, the distance between the two shooting locations is sufficiently long, so that the shooting location of the target content is not estimated based on the shooting location of the reference content. Yes. In this case, the shooting location of the reference content need not be deleted.

For the file F2 that is the target content and the file F1 that is the reference content, the distance between the shooting location parameter “point a” of the file F1 and the shooting location parameter “point b” of the file F2 is 500 meters. It is determined that the related determination condition is satisfied.
If it is determined in step S82 that it is 1000 meters or less, it is determined whether or not the time interval between the shooting time of the target content and the shooting time of the reference content is 60 minutes or less (step S83).

When the calculated time interval exceeds 60 minutes, the range in which the reference content can be moved in 60 minutes is wide, and it is set in advance that the shooting location of the target content is not estimated. In this case, the shooting location of the reference content need not be deleted.
On the other hand, if it is determined in step S83 that the time is 60 minutes or less, the shooting location of the reference content is determined so that the shooting location of the target content can be estimated within a range that can be moved within 60 minutes from the shooting location of the reference content. It is said that it needs to be deleted.

For example, the shooting time parameter “January 1, 2008 00:00:00” of the file F1, which is the reference content, and the shooting time parameter “January 1, 2008 0:00:00” of the file F2, which is the target content. Since the shooting interval with “second” is 10 minutes, it is determined that the related determination condition in step S83 is satisfied (step S83: YES).
Eventually, with regard to the shooting location parameters of the files F1 to F4, the related additional information deletion process causes the shooting location parameter “point a” of the file F1, the shooting location parameter “point b” of the file F2, and the shooting location parameter “point of the file F3”. c ”is deleted, and the shooting location parameter“ point d ”in the file F4 is not deleted.

Further, the name of the photographer of the reference content is deleted because it matches the related determination condition.
3.5. User Setting Process Next, the user setting process shown in steps S7 and S12 of FIG. 7 will be described.

FIG. 10 is a diagram showing a flow of setting processing by the user.
The user interface unit 201 displays a list of contents to be transmitted (step S61).
An example of screen display in this step will be described with reference to FIG.
FIG. 12 is a diagram illustrating an example of a screen on which the user interface unit 201 displays a list of transmission target contents regarding the shooting location parameters.

In FIG. 12, reference numeral 1100 denotes an operation screen displayed by the user interface unit 201. On the operation screen 1100, 1101 indicates an image of the image file 1, 1102 indicates an image of the image file 2, 1103 indicates an image of the image file 3, and 1104 indicates an image of the image file 4.
In FIG. 12, the same elements as those in FIG.

The user interface unit 201 acquires map information from a map information storage unit (not shown) and displays a map 1107 on the operation screen 1100.
Then, the user interface unit 201 displays the image of the image file in an overlapping manner at the position indicated by the setting value of the shooting location parameter extracted by the additional information analysis unit 205.
In the case of the list display of the four image files shown in FIG. 3, the image 1101 is displayed at the point P1111, the image 1102 is displayed at the point P1112, the image 1103 is displayed at the point P1113, and the image 1104 is displayed at the point P1114.

Next, the user interface unit 201 presents an output permission list, an output prohibition list, an out-list output setting value, and a related additional information list stored in the user setting storage unit 203 to the user (step S62). .
Here, a display example of the operation screen in this step will be described with reference to FIG.
FIG. 13 is a diagram illustrating an example of an operation screen displayed on the user interface unit 201 in the setting process by the user regarding the shooting location parameter.

In FIG. 13, the same elements as those in FIG.
The user interface unit 201 displays the setting values related to the shooting location parameters set in the output permission list and the output prohibition list acquired from the user setting storage unit 203 on the map 1107 displayed in step S61.
When displaying the setting of the output permission list and the setting of the output prohibition list, the range A1125 of the region M set in the output permission list and the range A1136 of the region X set in the output prohibition list are displayed on the map 1107. Is displayed at the corresponding position.

The area N and the area Y which are areas outside the range of the map 1107 are not displayed.
Next, the user interface unit 201 prompts the user to additionally register or modify an output permission list, an output prohibition list, an out-of-list output setting value, and a related additional information list stored in the user setting storage unit 203 ( Step S63).
The user uses the user operation receiving unit 209 to perform the additional registration and correction.

Specifically, the user uses the user operation accepting unit 209 to add a range where the output of the shooting location parameter is permitted and a range where the output is prohibited on the map 1107 displayed in step S62, or display in step S702. Modify the specified range.
Then, the user interface unit 201 uses the user operation reception unit 209 to update the items that have been additionally registered and corrected by reflecting them in the output permission list, output prohibition list, out-list output setting value, and related additional information list. And stored in the user setting storage unit 203.

And the terminal device 100 repeats the process from step S61 to step S63 until the setting process by the user is completed, and completes this process when the setting process by the user is completed.
The processing in the embodiment of the present invention has been described above.

4). The present invention has been described based on the above embodiments, but the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the present invention. Of course, can be added.
(1) In the above embodiment, the case where the terminal device 100 transmits content to the server device 101 and the content browsing device 102 browses the content published by the server device 101 has been described, but the present invention is not limited thereto.

For example, the terminal device 100 may perform similar processing in various cases where the terminal device 100 outputs content to the outside of the device.
Also, when the terminal device 100 transmits content to the content browsing device 102 via the server device 101, such as when content is attached to an e-mail, the terminal device 100 may perform similar processing. Good.

Moreover, when the terminal device 100 directly transmits content to the content browsing device 102 as in content sharing by peer-to-peer connection, the terminal device 100 may perform similar processing.
Further, the terminal device 100 may perform the same processing when the terminal device 100 directly records content on the medium, such as content sharing using a memory card as a medium.
(2) In the embodiment of the present invention, the terminal device 100 has a function of deleting the additional information and the related additional information, and the server device 101 has the content from which the terminal device 100 has deleted the additional information and the related additional information. However, the present invention is not limited to this. However, the present invention is not limited to this.

For example, the server device 101 may be configured to have all or part of the configuration of the terminal device 100 illustrated in FIG.
In this case, the terminal device 100 transmits the content from which the additional information and the related additional information are not deleted to the server device 101. Then, the server apparatus 101 deletes the additional information and the related additional information from the received content, and publishes the content from which the additional information and the related additional information are deleted to the content browsing device 102.

Further, the server apparatus 101 may include a user area that can be browsed only by the user and a public area that can be browsed by other users as the content storage area 202, and may perform a web photo album service.
In this case, the server device 101 stores the original content transmitted from the terminal device 100 in the user area, and stores the content obtained by deleting the additional information and the related additional information from the original content in the public area.

Further, the deletion of the additional information and the related additional information may be performed according to the number of contents stored in the server apparatus 101 as well as the content transmission / reception timing, or according to a user instruction.
(3) In step S2, the content output control unit 204 determines whether or not the related additional information deletion process is necessary according to the number of contents to be transmitted, but the present invention is not limited to this. For example, the user interface unit 201 may allow the user to select whether or not the related additional information deletion process is to be performed, and determine whether or not the related additional information deletion process is necessary based on the selection.
(4) In step S61, the content list display method using the shooting location parameter has been described, but the shooting time parameter is displayed in chronological order, grouped by the photographer name parameter, or displayed in a plurality of parameters. May be displayed hierarchically.

For example, the content list is displayed in a calendar format using the shooting time parameter. Then, only the content list regarding the content of the selected date may be displayed on the map using the shooting location parameter.
(5) In step S62, the method for presenting the output permission list and the output prohibition list related to the shooting location parameter has been described. However, a list of setting values for each registered parameter is presented, and the shooting time parameter is displayed in a calendar format. May be.

Further, the user interface unit 201 may display the parameter setting value of the additional information for each content as a user interface, and the user may set and change after confirming the displayed setting value. Also, the set value may be set collectively for each parameter classification of the additional information.
(6) In step S63, the user specifies a plurality of points on the map 1107 displayed on the operation screen 1100, and the user interface unit 201 generates a rectangle from the specified point, and the range indicated by the rectangle May be set as the setting value of the shooting location parameter in the output permission list or output prohibition list.
(7) Although it has been described that the additional information deletion unit 206 performs processing in the order of the output prohibition list, the output permission list, and the output setting value outside the list, the present invention is not limited to this. For example, the processing order of these steps may be determined according to the priority set by the user or set in advance.

Furthermore, the user may specify processing priority via the user interface unit 201, and the additional information deletion unit 206 may determine the processing order according to the priority.
(8) The content output control unit 204 and the content output unit 208 have been described to output the content excluding the parameter setting value of the additional information marked for deletion, but are not limited thereto. For example, the additional information may be overwritten with another set value and output. Another set value may be a set value designated by the user or a special value indicating that the deletion process has been performed.
(9) Although it has been described that the related additional information deletion unit 207 performs the related additional information deletion processing after the additional information deletion processing of the other content, the processing order may be changed.
(10) The process in step S32 may be omitted.

In this case, the related additional information deletion unit 207 determines whether it is necessary to delete the parameter setting value of the related additional information based only on the relationship between the additional information.
(11) In steps S82 to S84, the related additional information deletion unit 207 has both a condition that the shooting location distance of the plurality of contents is equal to or less than a predetermined distance and a condition that the shooting interval of the plurality of contents is equal to or less than the predetermined interval. In the case of being established, the example in which it is determined that the shooting locations of the plurality of contents are related has been described. However, if one of the conditions is satisfied, it may be determined that the shooting locations of the plurality of contents are related. .

Further, the processing in step S82 may be omitted. In this case, the related additional information deletion unit 207 determines that the shooting locations of the plurality of contents are related regardless of the shooting location distance if the shooting location intervals of the plurality of contents are equal to or smaller than the predetermined interval.
Further, the processing in step S83 may be omitted. In this case, if the shooting location distance of the plurality of contents is equal to or less than the predetermined distance, the related additional information deleting unit 207 determines that the shooting locations of the plurality of contents are related regardless of the shooting interval.

Further, the processing in step S82 and step S83 may be omitted. In this case, the related additional information deletion unit 207 determines that the shooting locations of the plurality of contents are always related.
In step S82, the related additional information deleting unit 207 has been described as evaluating the condition that the shooting distances of the plurality of contents are equal to or less than the predetermined distance. You may evaluate as conditions.

In step S83, it has been described that the related additional information deletion unit 207 evaluates the condition that the shooting interval of the plurality of contents is equal to or less than the predetermined interval. You may evaluate as conditions.
Further, in step S83, the related additional information deletion unit 207 has been described as evaluating the condition that the shooting intervals of the plurality of contents are equal to or less than the predetermined interval. However, instead of using the shooting interval as a difference in shooting time, the shooting order is not used. An imaging interval as a difference between the two may be used. For example, since a photo file taken with a digital camera is assigned a sequential file name in the shooting order, the related additional information deletion unit 207 uses the sequential number of the file name to change the shooting order to five before and after. It is determined that there is a relevance for the photo file. Furthermore, a combination of a difference in shooting time and a difference in shooting order may be used as the shooting interval.
(12) In the related additional information deleting process, the related additional information deleting unit 207 is based on the condition that the shooting location distance of the plurality of contents is equal to or smaller than the predetermined distance and the condition that the shooting interval of the plural contents is equal to or smaller than the predetermined distance. Although the case where the deletion of the shooting location parameter is determined has been described, the deletion of the shooting time parameter may be determined and deleted based on these conditions, or the file name may be changed.

Further, the related additional information deletion unit 207 determines deletion of the shooting location parameter based on the condition that the shooting location distance of the plurality of contents is equal to or less than the predetermined distance and the condition that the shooting interval of the plurality of contents is equal to or less than the predetermined interval. However, the additional information deletion determination process may be performed based on a combination of one or more conditions on the condition of the relationship between a plurality of additional information.
(13) Although the related additional information deleting unit 207 has been described as deleting the related additional information when the related condition is satisfied, the related additional information may not be deleted when the related condition is satisfied.
(14) The user interface unit 201 confirms the execution of the process with respect to the user and executes the process when instructed to execute the process before executing each process in the terminal device 100 as necessary. Also good.

For example, prior to the related additional information deletion process, the user interface unit 201 displays a message “Do you want to delete the shooting location parameter of image 1 related to image 2?” To the user. May be.
(15) Although the additional information has been described with the example including the shooting time parameter, the shooting location parameter, the photographer name parameter, and the comment information parameter, the present invention is not limited thereto. It may be composed of information such as a photographer's address, a photographer's e-mail address, a photographing device manufacturer name, a photographing device model name, information about a subject, a search keyword, shutter speed, and white balance.
(16) The setting value of the output permission list may be not only the setting of the specific value but also the setting of the range including the specific value, the setting of the range not including the specific value, the setting of the entire value, etc. .

When “all setting values” are designated, the setting value is managed by a special value assigned to “all setting values”, a flag indicating “all setting values”, or the like.
In addition, the “region” designation method is specified by “center point and radius”, “upper left point and lower right point”, “polygon apex”, “zip code, area code, etc.” as setting values. This is achieved by managing "regions".
(17) The output prohibition list may be capable of setting not only a specific value but also a range including a specific value, a range not including a specific value, and an overall value.

When “all setting values” are designated, it is realized by managing a special value assigned to “all setting values” as a setting value, a flag indicating “all setting values”, and the like.
In addition, the “region” designation method is specified by “center point and radius”, “upper left point and lower right point”, “polygon apex”, “zip code, area code, etc.” as setting values. This is achieved by managing "regions".
(18) As for the relation determination condition, not only the setting of the specific value but also the setting of the range including the specific value, the setting of the range not including the specific value, the setting of the whole value, and the combination of the conditions by a plurality of parameters are possible. It may be.
(19) Although the terminal device 100 is a mobile phone, it may be another device. Any device that handles content such as a digital TV, a DVD (Digital Versatile Disc) player, a mobile phone, a digital camera, a music player, or a personal computer may be used.
(20) Specifically, each of the above devices is a computer system including a microprocessor, a ROM, a RAM, a hard disk unit, a display unit, a keyboard, a mouse, and the like. A computer program is stored in the ROM, RAM, or hard disk unit. Each device achieves its function by the microprocessor operating according to the computer program. Here, the computer program is configured by combining a plurality of instruction codes indicating instructions for the computer in order to achieve a predetermined function.

Each device is not limited to a computer system including all of a microprocessor, a ROM, a RAM, a hard disk unit, a display unit, a keyboard, a mouse, and the like, and may be a computer system including a part of them.
(21) A part or all of the components constituting each of the above devices may be configured by one system LSI (Large Scale Integration).
