  In addition, after setting the release image display area 601 once, when the other release image display area 601 is in focus, the set release image display area 601 is touched, so that the focus is adjusted. When moving to the touched release image display area 601, it is identified and displayed that the release operation direction object 603 set for the moved release image display area 601 is selected.

  In the security cancellation screen 600 shown in FIG. 7, the image data and the operation direction are selected, the image data displayed in the upper left cancellation image display area 601 is selected, and the cancellation operation direction object 603 is displayed. As can be seen, the upward direction is selected.

  The image data and the operation direction are displayed in the release image display area 601 and the release operation direction object 603 using the image data and the operation direction registered using the release image registration screen 300.

  When the selected image data and the operation direction are correct on the security release screen 600, that is, when the image data and the operation direction registered on the release image registration screen 300 are selected, the security is released and the image is taken. Use of the device 100 is started.

FIG. 8 shows a menu screen 700 in the photographing apparatus 100, which displays a list of various services available in the photographing apparatus 100, and the user desires from the services displayed on the menu screen 700. You can receive the service by touching the service. The menu screen 700 is displayed on the liquid crystal display 117 of the photographing apparatus 100.

  The menu screen 700 also displays a service for displaying the menu detail screen 200 shown in FIG. 3, and the user touches and selects the service to determine whether to perform security settings for the photographing apparatus 100. I can decide.

  In FIG. 9, when the image data and the operation direction selected by the user are not correct on the security cancellation screen 600, that is, when the image data and the operation direction registered on the cancellation image registration screen 300 are not selected. , A warning screen 800 for warning the user to that effect is shown. The warning screen 800 is displayed on the liquid crystal display 117 of the photographing apparatus 100.

  When the user recognizes that the contents displayed on the warning screen 800, that is, the selected image data and the operation direction are incorrect on the security release screen 600, the user again sets the image data and the operation direction on the security release screen 600. The user touches an OK button 801 on the warning screen 800 for selection. Then, the security cancellation screen 600 is displayed on the liquid crystal display 117, and the user again selects the image data and the operation direction.

  FIG. 10 shows an image registration screen for cancellation 300. The image registration screen for cancellation 300 has a function of canceling the security setting of image data that has already been set with security, and touches the image data to be canceled. In this state, the security setting of the image data can be canceled by moving it outside the range of the registered image display area 301 in which the image data is displayed. In FIG.

  For example, as shown in FIG. 10, when the image data is moved outside the range of the registered image display area 301 while touching the image data displayed in the upper left registered image display area 301, the image data It is considered that the security setting set to is canceled, and the unlocked image registration screen 300 is not displayed.

  On the other hand, when canceling the security setting set for the image data, a deletion button (not shown) is provided on the cancellation image registration screen 300, and the deletion button is pressed while image data to be deleted is selected. It is also possible to cancel it.

  FIG. 11 is a flowchart showing processing for setting security for the image capturing apparatus 100 in the image capturing apparatus 100 according to the embodiment of the present invention. Each processing step in this flowchart is under the control of the system controller 110. The process is executed.

  First, before proceeding to step S100, if the security setting has already been made for the photographing apparatus 100, after the security is released, the menu screen 700 is displayed, and a service related to the security setting is selected from the services. On the other hand, if the security setting has not been made for the photographing apparatus 100, the security screen is not released and the menu screen 700 is displayed, and the service relating to the security setting is selected from the services. It is a premise.

  As described above, the security setting means that when the user selects the correct image data and the operation direction for the correct image data when using the image capturing apparatus 100, the use of the image capturing apparatus 100 can be started. It basically shows that the setting is performed.

  In step S100, it is determined whether or not an instruction input for performing security setting has been accepted for the security setting selection field 201 of the menu detail screen 200. If it is determined that the instruction has been accepted, the process proceeds to step S101 and is not determined to have been accepted. If so, the process ends.

  In the determination method in this step, when the determination button 202 is touched in a state where the security setting selection field 201 is selected to perform security setting, it is determined that an instruction input for performing security setting has been received, and the security setting selection field 201 If the decision button 202 is touched in a state in which “No security setting” is selected, it is not determined that an instruction input for performing security setting has been received.

  In step S101, as described above, whether or not the image data exists in the folder for storing the image data with the security settings (the image data for release and the same as the correct image data) existing in the memory card 115 is stored. If it is determined that it is present, the process proceeds to step S102. If it is not determined that it exists, the process proceeds to step S104.

  In this step, even when image data exists in the folder, when changing the image data to be registered, a screen (not shown) for accepting a change instruction is displayed on the liquid crystal display 117, and the change is made. If the instruction is issued by the user, the process proceeds to step S104. If it is accepted that no change instruction is given, the process proceeds to step S102.

  Alternatively, in step S100, a screen for accepting a change instruction (not shown) is displayed, and when a change instruction is given by the user, the process proceeds to step S104, and if a change instruction is not given, It is also possible to take an aspect in which the process proceeds to step S102.

  In step S102, information indicating that the security setting is performed on the image capturing apparatus 100 is stored in the security setting table illustrated in FIG.

  The security setting table is a table for storing whether or not security setting is performed in the photographing apparatus 100. When security setting is performed, ON is stored, and when security setting is not performed, OFF is stored.

  When step S102 ends, the process proceeds to step S103, and in step S103, the menu screen 700 is displayed.

  In step S104, processing for registering image data necessary for canceling security is executed. Details will be described with reference to FIG. Then, when this process ends, the process proceeds to step S102.

  FIG. 12 is a flowchart showing processing for registering image data necessary for releasing security. Each processing step in this flowchart is executed under the control of the system controller 110. The

  In step S200, in order to acquire image data for user selection when releasing security, the image data is acquired from a folder in the memory card 115 that stores the image data obtained at the time of shooting. Each image data is accompanied by information for uniquely identifying the image data, for example, a file name.

  In step S201, when the image data acquired in step S200 is image data shot by continuous shooting (moving images, the number of shots taken within a predetermined time exceeds a predetermined number, a plurality of shots by one shooting operation). If the image data is not image data captured by continuous shooting such as a moving image, the process proceeds to step S203.

  In step S202, image data that is in focus is acquired from among the image data captured by the continuous shooting acquired in step S200. If there are a plurality of in-focus image data, for example, the image data obtained by photographing first is acquired, and information indicating that the other is not displayed is stored in the buffer memory 111. .

  In step S203, the image data obtained in step S202 and the image data obtained in step S201 among the image data obtained in step S200 are considered to have not been photographed. If it is not determined that the face is present, the process proceeds to step S204. If it is determined that the face is present, the process proceeds to step S205.

  In step S204, a similar composition is formed using the image data acquired in step S202 and the image data acquired in step S201 from the image data acquired in step S200, which is considered not to be captured by continuous shooting. If it exists, information indicating that one of the image data can be displayed and the other image data having the same composition is not displayed is stored in the buffer memory 111.

  In step S205, the image data is included in the image data using the image data acquired in step S202 and the image data acquired in step S201 from the image data acquired in step S201. When the coordinates, size, and number of human face frames are similar, information indicating that one of the image data can be displayed and the other similar image data is not displayed is buffer memory 111. To remember.

  As for the coordinates, size, and number of the above-mentioned human face frame, an arbitrary value is used to obtain the difference in the coordinates, size, and number of the human face frame between the respective image data. You may obtain | require by whether it is in the range of a value.

  In step S206, it is determined whether or not the number of displayable image data required for releasing security is greater than or equal to a predetermined number. If it is determined that the number is greater than or equal to the predetermined number, the process proceeds to step S207. If it is not determined that the number is greater than the predetermined number, the process proceeds to step S210.

  As a determination method in this step, information indicating that display is possible or non-display stored in the buffer memory 111 in steps S204 and S205 may be used.

  In step S207, the cancellation image registration screen 300 is displayed, and the image data determined to be displayable is displayed in the registration image display area 301. Then, when it is detected that the registration button 304 is touched, the user registers it as a registration target. The selected image data, that is, the registered image selection field 302 is marked is acquired. In step S208, the operation direction for the image data acquired in step S207, that is, the selected registered operation direction object 303 is acquired. To do.

  Then, using the acquired image data and operation direction on the confirmation screen 400, the selection schedule display area 401 and the operation direction schedule object 402 are displayed. When the Yes button 403 is touched, the process proceeds to step S209. When the No button 404 is touched, the process is terminated. Note that the upper limit number of selectable image data can be arbitrarily set.

  In step S209, the image data acquired in steps S207 and S208 is moved to a folder for storing image data for which security settings have been made. During this movement, a screen indicating that the image data shown in FIG. 6 is moving is displayed.

  When the movement is completed, information regarding the moved image data is stored in the registered image table and the dummy image table shown in FIG.

  The registered image table is a table for storing information related to correct image data among image data to be selected by the user when canceling security. The registered image data (file name, etc.) is set. The registered image data (same as correct image data and release image data) and a registration direction item indicating the operation direction for the security-set image data are provided.

  In this step, among the data moved in step S209, the operation direction specified from the image data acquired in step S207 and the registered operation direction object 303 acquired in step S208 is stored.

  The dummy image table is a table for storing image data other than the image data for which security is set, and dummy image data and dummy image data indicating image data (file name, etc.) other than the image data for which security is set. Includes a display enable / disable flag indicating that display is possible or non-display.

  The image data not selected in step S207 and step 208 (file name etc.) or the image data not displayed in step S204 and step S205 (file name etc.) is stored in the dummy image data, and the display enable / disable flag is displayed. In step S204 and step S205, information indicating that display is possible or not is stored in the buffer memory 111.

  In step S210, a warning screen (not shown) indicating that the image data that can be displayed is insufficient is displayed on the liquid crystal display 117, and the process ends.

  FIG. 13 is a flowchart showing processing for releasing security when using the image capturing apparatus 100. Each processing step in this flowchart is executed under the control of the system controller 110.

  In step S300, the security cancellation screen 600 is displayed, and one image data specified from the registered image data in the registered image table stored in the destination folder moved in step S209 is acquired for the cancellation image display area 601. In addition, three displayable image data specified from the dummy image data in the dummy image table are acquired and displayed.

  In step S <b> 301, when an operation direction instruction is input in a state where a mark is given to the release image display area 601 touched by the user, that is, the release image selection field 602, of the four release image display areas 601. The image data and the operation direction are acquired.

  In step S302, it is determined whether or not the image data acquired in step S301 and the operation direction are correct. If it is determined that the image data is correct, the process proceeds to step S303 and is not determined to be correct. If so, the process proceeds to step S304.

  As an example of the determination method in this step, it is determined whether or not the image data acquired in step S301 and the operation direction are present in the registered image table. If it is not determined that it exists, it is determined that it is not correct.

  In step S303, security is released, that is, the use of the photographing apparatus 100 is started, and the menu screen 700 is displayed. In step S304, information indicating that the selected image data and the operation direction are incorrect is displayed on the warning screen 800. Use to display.

  This flowchart can be repeated as many times as the number of registered image data registered in the registered image table, and can be repeated a predetermined number of times within the range of the number of registered image data.

Furthermore, in the present embodiment, the touch panel type photographing apparatus has been described as a premise, but the present invention is not limited to this mode. When the cursor is placed on the release image display area 601 and the cursor key 124 is pressed, the selected state is set, and the cursor is placed on the registration operation direction object 303 and the release operation direction object 603 for registration and release. It is possible to cancel security by registering and selecting image data and an operation direction.
[Second Embodiment]

  Next, a second embodiment will be described. In the first embodiment, when using the image capturing apparatus 100, registered image data and dummy image data are displayed, and when the selected image data and the operation direction for the image data are correct, the security is canceled, Although the imaging apparatus 100 can be used, in the second embodiment, when the selected image data is correct and the operation direction is incorrect, some functions provided in the imaging apparatus 100 can be used. Is.

  For example, if it is an application for using the Internet or e-mail, etc., it will handle highly confidential information such as user's personal information, so set the security higher, while referring to the image obtained by shooting If it is an application for performing, etc., it is considered that the security is low so that even if it is disclosed to a third party, it is considered that the security is set low.

  In particular, when the user wants to use the photographing apparatus 100 immediately, if the selected image data is correct but the operation direction is incorrect, the user again selects the image data and performs an operation of instructing the operation direction. However, it takes time to use the photographing apparatus 100, and it is undeniable that the troublesome work remains.

  However, if all such authentication functions are to be lost, it is necessary to ensure a certain level of security because this would lead to misuse by a third party, etc. In this embodiment, these problems are solved. This is the main purpose.

  Basically, since the same configuration and processing as those of the first embodiment are provided, the description is omitted, and when the description is made using the same configuration and processing, the description is performed using the same reference numerals.

  FIG. 15 is a flowchart illustrating a process obtained by improving the security setting process for the photographing apparatus 100 illustrated in FIG. 11, and the process of step S <b> 400 is different from that of the first embodiment.

  In step S100, when an instruction to perform security setting is received in the security setting selection field 201 of the menu detail screen 200, in step S400, a highly confidential application is selected from among the applications installed in the photographing apparatus 100. An important application selection screen 900 (see FIG. 17) for displaying is displayed on the liquid crystal display 117.

  The important application selection screen 900 is a confidentiality check box 901 for selecting an important application with high confidentiality with respect to the application installed in the photographing apparatus 100, and an application displaying the application installed in the photographing apparatus 100. A display list 902 is provided, and a confidentiality check box 901 is displayed corresponding to the application displayed in the application display list 902.

  In order to select a highly confidential application, the user touches the confidentiality check box 901 (or application display list 902) corresponding to the application, so that a check mark is input to the confidentiality check box 901 and the selection is made. Do.

  Then, after the application is selected, the user touches the apply button 903 to register the application whose check mark is input in the confidentiality check box 901 as a highly confidential application.

  This registration destination is an activation target application identification table (see FIG. 18) that stores activation application identification information for identifying applications that can be activated in accordance with the correctness of the operation direction for the selected correct image data.

  In this activation target application specifying table, image selection OK / NG indicating whether the selection of image data is correct or incorrect, operation direction OK / NG indicating whether the operation direction is correct or incorrect, and image data An application that can be activated according to the selection and the correct operation direction, that is, an application that can be activated, that is, a highly confidential application or an application with a low confidentiality is provided.

  If the data of the image selection OK / NG is the image selection OK, that is, the selection of the image data is correct, and if the data of the operation direction OK / NG is the operation direction OK, that is, the operation direction is correct, an application including a highly confidential application is included. Since it can be activated, the application name is stored as information for identifying the application.

  In the present embodiment, AAAA and BBBB are applications with high confidentiality, and CCCC and DDDD with low confidentiality can also be activated.

  If the data of the image selection OK / NG is the image selection OK, that is, the selection of the image data is correct, and the data of the operation direction OK / NG is the operation direction NG, that is, the operation direction is incorrect, the application with low confidentiality ( CCCC, DDDD) can be activated.

  When such registration is completed, the processing after step S101 is performed as in the first embodiment.

  Next, FIG. 16 shows a flowchart showing a process for improving the process of releasing the security when using the photographing apparatus 100 shown in FIG. 13, and the first embodiment is different from the step S500. The processing up to step S504 is different.

  In step S500, it is determined whether the image data acquired in step S301 is correct. If it is determined that the image data is correct, the process proceeds to step S501, and if it is not determined that the image data is correct, The process proceeds to step S304.

  In step S501, it is determined whether or not the operation direction acquired in step S301 is correct. If it is determined that the operation direction is correct, the process proceeds to step S502. The process proceeds to step S503.

  In step S502, menu information to be displayed on the menu screen 700 is created. In creating the menu information, the activation target application specifying table is read. In step S501 and step S502, since the selected image data and the operation direction are determined to be correct, the image selection OK / NG is changed to the image selection OK and The operation direction OK / NG obtains data, AAAA, BBBB, CCCC, DDDD registered in the startable application name corresponding to the operation direction OK.

  When the application name is acquired, menu information for starting the application is created.

  A display example of the menu screen 700 is shown in the upper part of FIG. 24. This menu screen 700 has the same configuration as the menu screen shown in FIG. 8, and the display contents are different.

  That is, an application that can be activated from the menu screen 700 is displayed. In the present embodiment, AAAA, BBBB, CCCC, and DDDD are displayed. When the user touches an application that the user desires to activate and performs selection, FIG. The startup application execution table shown in FIG. 18 is read, and the execution file of the application to be started is started.

  The startup application execution table includes a menu display title corresponding to the application name and a startup application for specifying an execution file for starting the application.

  For example, when the user selects AAAA displayed on the menu screen 700, AAAA that is the application name is acquired from the menu screen 700 as information for identifying AAAA, and the activation application execution table corresponding to AAAA is acquired. XXX.ppp, which is a startup application (file name, etc.) corresponding to AAAA of the menu display title, is acquired, and the application is started by executing the execution file having the file name of XXX.ppp provided in the photographing apparatus 100 To do.

  In this step, the activation target application specifying table shows a mode in which the image selection OK / NG registers the image selection OK and the operation direction OK / NG registers the operation direction OK. In addition, if the operation direction is correct, all the applications installed in the image capturing apparatus 100 can be used, and a configuration in which the data is not provided is also assumed. In this case, menu information that displays all applications without reading the activation target application identification table is generated.

  In step S503, menu information to be displayed on the menu screen 700 is created. In creating the menu information, the activation target application specifying table is read. In step S501 and step S502, since the selected image data is determined to be correct and the operation direction is determined to be incorrect, the image selection OK / NG is changed to image selection OK and The operation direction OK / NG acquires data, CCCC, and DDDD registered in the startable application name corresponding to the operation direction NG.

  When the application name is acquired, menu information for starting the application is created.

  A display example of the menu screen 700 is shown in the lower part of FIG. 24. The menu screen 700 has the same configuration as the menu screen shown in the upper part of FIGS. 8 and 24, and the display contents are different.

  That is, CCCC and DDDD with low confidentiality are displayed on the menu screen 700 as applications that can be activated by the user, and AAAA and BBBB with high confidentiality are not displayed. Thereafter, the application activation method to be executed from the menu screen 700 is as described above.

  Note that the display method of the menu screen 700 is that the security release screen 600 is displayed in an area where the application name of the menu screen 700 is displayed, accepts the selection and operation direction of the image data, and the image data. It is also possible to display an application with low confidentiality (CCCC, DDDD) in a state in which it is determined to be correct, and display an application with low confidentiality (CCCC, DDDD) at the timing when the correct operation direction is accepted.

In this case, after the process of step S500, a highly confidential application is identified, menu screen information is generated, and the menu screen 700 is displayed. Thereafter, the process of step S501 is performed, and if the operation direction is correct, A highly confidential application (AAAAA, BBBB) is specified, menu screen information is generated, and the menu screen 700 is displayed.
[Third Embodiment]

  Next, a third embodiment will be described. In the first embodiment, the registered image data is limited to the use of the photographing apparatus 100. However, in the present embodiment, the registered image data and the dummy image data are displayed and authenticated for each application. The mode to perform is taken. Therefore, a mode of registering image data used in an application as registered image data will be described.

  Basically, since the same configuration and processing as those of the first embodiment are provided, the description is omitted, and when the description is made using the same configuration and processing, the description is performed using the same reference numerals.

  FIG. 19 is a flowchart showing a process obtained by improving the security setting process for the image capturing apparatus 100 shown in FIG. 11, and the process of step S600 is different from that of the first embodiment.

  In step S100, when an instruction input for performing security setting is received in the security setting selection field 201 of the menu detail screen 200, in step S600, for any application installed in the image capturing apparatus 100, for any application. A security setting application selection screen 1000 (see FIG. 22) for selecting whether to set security is displayed on the liquid crystal display 117.

  The security setting application selection screen 1000 displays an application ID 1001 indicating NO for uniquely identifying an application installed in the photographing apparatus 100, a target application 1002 indicating the name of the application, and whether or not security settings have already been performed for the application. A security setting status 1003 indicating the above, and a close button 1004 for closing the security setting application selection screen 1000.

  It should be noted that the security setting status 1003 is displayed as “done” if it is determined that the security setting has been made if it has been registered in the security setting table shown in FIG. 23, and “not yet” if it has not been registered. ing.

  This security setting table includes an application name for identifying an application, and ON / OFF indicating whether or not security setting has been performed for the application.

  That is, “ON” is displayed when ON is set in the security setting table, and “NO” is displayed when OFF is set.

  In this step, for example, when the user makes a selection by touching the target application 1002 displayed on the security setting application selection screen 1000, information for identifying the selected application, that is, AAAA which is the application name is acquired.

  When such selection is completed, the processing after step S101 is performed as in the first embodiment.

  Next, FIG. 20 shows a flowchart showing a process improved from the process of registering image data necessary for releasing the security shown in FIG. The processing in step S700 is different.

  In step S700, the image data used in the application corresponding to the application name acquired in step S600 is acquired.

  In the first embodiment, image data existing in the image capturing apparatus 100 is targeted. However, in this embodiment, the security setting of the application is performed using the image data used by the user himself / herself in the application.

  If the user is image data that has been worked on an application in the past, it is assumed that the application and the image data used in the application are likely to be associated with each other. By using it for authentication when using, it takes a mode in consideration so that the user can use it easily (remaining in its own memory) while maintaining security.

  In order to specify the image data used in the application, it is possible to specify from the log that is output when the application is started. Therefore, based on the information in this log, the use image table shown in FIG. create.

  The usage image table includes an application name indicating the name of the application and a usage image indicating the file name of the image data used in the application. The usage image information may be created even when the application is closed. It is good, and you may make it at a regular timing. However, it is assumed that information indicating which image data was used by which application is output as a log.

  In this step, for example, if the application name AAAA is acquired in step S600, kkkk.jpg, ttt.jpg, and ssss.jpg are acquired as the usage images of the usage image table corresponding to AAAA.

  When the image data is acquired in this way, the processing after step S201 is performed as in the first embodiment.

  In step S209, the registered image data is stored in the registered image table. In this embodiment, the registered image data is registered for each application. Therefore, the configuration is shown in FIG. 14, as shown in FIG. An application name is added to the configuration, and the registered image data is registered in the registered image table including the application name acquired in step S600.

  Next, FIG. 21 shows a flowchart showing a process for improving the process of releasing the security when using the photographing apparatus 100 shown in FIG. 13. The first embodiment is different from the first embodiment in steps S800 and S800. Step S801 is different.

  In step S800, the application selected from the menu screen 700 is received to identify the application to be activated. In step S801, registered image data corresponding to the application received in step S800 is registered in the registered image table shown in FIG. Get from.

  For example, when the user makes a selection by touching the application name AAAA on the menu screen 700, AAAA as the application name is acquired from the menu screen 700 as information for identifying AAAA, and a registered image table corresponding to this AAAA. Identify the data.

  As a result, similar to the first embodiment, it is possible to specify registered image data and an operation direction for performing the processing after step S300.

  In the present embodiment, registered image data is used for each application. However, without being limited to this mode, for example, as shown in FIG. 25, a selected check box 1005 and an apply button 1006 are displayed on the security setting application selection screen 1000. It is also possible to adopt a mode in which it is possible to perform setting in a lump for a plurality of applications targeted for security setting.

  When the user selects a target application by touching the security setting application selection screen 1000, the selected check box 1005 is marked. When the user touches and presses the apply button 1006, the selected check box 1005 is marked. Configure security settings for the selected application.

  In this case, in step S700, all image data used in all selected applications are acquired from the use image table and the subsequent processing is performed. In step S209, the same registration is performed for each application name. Register image data and registration direction.

  On the other hand, the processing from step S700 to step S209 is performed for each selected application without using the same registered image data and registration direction, and each of the registered image data and registration direction is different. Can also be registered in a series of flows.

  It should be noted that display may be performed so that the same registered image data and registration direction are registered so that they can be identified on the security setting application selection screen 1000.

  Furthermore, even if the security setting status has already been completed or if it has been selected on the security setting application selection screen 1000, the setting may be performed again. A mode of performing setting may be taken.

  As a release method, using the release image registration screen 300 shown in FIG. 10, all image data is moved outside the registration image display area 301, and then touched and pressed the registration button 304. At the timing, ON / OFF of the security setting table is set to OFF.
