Description

  The present invention relates to a mobile terminal device such as a mobile phone or a PDA (Personal Digital Assistant).

  In recent years, mobile phones with cameras equipped with GPS (Global Positioning System) functions have been commercialized. In such a mobile phone, geographical position information such as latitude and longitude measured by GPS can be added to image data taken by a camera and stored in a memory (for example, a memory card).

  In this case, if an operation for positioning with GPS is required every time a photograph is taken, the usability is deteriorated. Therefore, such a cellular phone can be configured such that when a photograph is taken, position information is automatically measured and added to image data (see, for example, Patent Document 1).

JP 2008-205755 A

  By the way, the image data to which the position information is added can be uploaded on a web server such as a user's home page. In this case, the photograph can be displayed on the map using predetermined application software. For example, the location of the location information added to the image data is displayed on the map with a flag icon or the like, and when the location is clicked, a photo corresponding to the location is displayed.

  However, when the position information is automatically added to the captured image data as described above, the position information is not included in the photograph that the user does not want, for example, the photograph of the user's home or office. There is a risk of being added. When such a photo is uploaded and displayed on the map as described above, personal information such as the user's home may be unintentionally disclosed to the public.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a portable terminal device that can prevent display of position information of an image that is not desired by a user by a simple operation.

  The mobile terminal device according to the present invention includes an image pickup unit, a storage unit that stores image data acquired from the image pickup unit, a position acquisition unit that acquires position information, and the image data based on preset exclusion information. A display prohibiting unit for prohibiting display in which the image based on the image and the positional information of the image are associated with each other.

  For example, the display prohibition unit may be configured to determine whether to store the position information in association with the image data based on the exclusion information.

  With such a configuration, it is possible to prevent display of image position information that the user does not want.

  In the mobile terminal device according to the present invention, the gradual information may include information defining an exclusion range of the position information. In this case, when the position information is within the exclusion range, the display prohibition unit does not store the position information in association with the image data.

  With such a configuration, if a place that is not desired to be disclosed, such as a home, is set as an exclusion range, position information corresponding to this place is not stored corresponding to the image data.

  In this case, when the position information is within the exclusion range, the display prohibition unit stores, instead of the position information, alternative position information indicating a predetermined position outside the exclusion range in association with the image data. It can also be set as such a structure.

  With such a configuration, when an image is associated with map information, it is possible to display an approximate shooting location on the map without knowing the exact shooting location.

  In the mobile terminal device of the present invention, the exclusion information may include information defining an exclusion time zone. In this case, the display prohibition unit does not store the position information in association with the image data in the exclusion time zone.

  With such a configuration, when shooting at a place that you do not want to open, such as at home, if you set the time zone at that location as an excluded time zone, it will correspond to the image data shot during this time zone. Position information is not stored.

  The mobile terminal device of the present invention may be configured to include a setting processing unit that sets the exclusion information based on an external operation.

  With such a configuration, the user can freely set the exclusion range and the exclusion time zone.

  The portable terminal device of the present invention may be configured to include a notification unit. At this time, when the display prohibition unit determines not to store the position information corresponding to the image data based on the exclusion information, the display prohibition unit notifies the notification unit to that effect, and based on the notification, When an operation for permitting storage of the position information is performed, the position information may be stored in association with the image data.

  With such a configuration, even in the exclusion range or exclusion time zone, if the user desires, the position information can be stored in association with the image data, which improves usability.

  ADVANTAGE OF THE INVENTION According to this invention, the portable terminal device which can prevent that the positional information on the image which a user does not want is displayed by simple operation can be provided.

The direction key 32 is mainly operated when a desired menu is selected from various menus displayed on the display screen. The decision key 33 is mainly operated when deciding on the selected menu or agreeing (OK) with the contents displayed on the display screen. The call key 34 is mainly operated when starting a call, and the call end key 35 is mainly operated when ending a call. The numeric keypad 36 is mainly operated when inputting characters (Hiragana, Katakana, Alphabet), numbers, and symbols. The clear key 37 is mainly operated when erasing input characters and the like. It should be noted that a part of the function of the numeric keypad 36 may be realized by a QWERTY key or the like.

  A camera module 11 is arranged inside the first cabinet 1. A lens window (not shown) of the camera module 11 faces the back surface of the first cabinet 1, and an object image is taken into the camera module 11 from the lens window.

  A display 21 is arranged in the second cabinet 2. As will be described later, the display 21 includes a liquid crystal panel 21a and a panel backlight 21b that illuminates the liquid crystal panel 21a. The display 21 may be configured by other display elements such as an organic EL.

  A touch sensor 22 is arranged on the display screen side of the display 21. The touch sensor 22 has a transparent sheet shape, and the display screen of the display 21 can be seen through the touch sensor 22.

  The touch sensor 22 includes a first transparent electrode and a second transparent electrode arranged in a matrix. The touch sensor 22 detects a position on the display screen touched by the user by detecting a change in capacitance between the transparent electrodes, and outputs a position signal corresponding to the position. Note that the touch sensor 22 is not limited to a capacitive touch sensor, and may be a resistive touch sensor, a pressure sensitive touch sensor, or the like.

  The second cabinet 2 is connected to the first cabinet 1 by a slide mechanism unit 4 so as to be slidable in the X-axis direction of FIG. As shown in FIG. 1C, the slide mechanism unit 4 is constituted by a guide plate 41 and a guide groove 42. The guide plate 41 is provided at both left and right end portions of the back surface of the second cabinet 2, and has a protrusion 41a at the lower end thereof. The guide groove 42 is formed on the side surface of the first cabinet 1 along the sliding direction (X-axis direction in FIG. 1). The protrusion 41 a of the guide plate 41 is engaged with the guide groove 42.

  When the cellular phone is closed, the second cabinet 2 is almost completely overlapped with the first cabinet 1 as indicated by a one-dot chain line in FIG. In this state (closed state), all the keys of the operation key group 3a are hidden behind the second cabinet 2. The second cabinet 2 can be slid (opened) until the guide plate 41 reaches the terminal position of the guide groove 42. When the second cabinet 2 is fully opened, as shown in FIG. 1A, all keys of the operation key group 3a are exposed to the outside.

  In a state where all the keys are hidden, an operation input to the mobile phone can be performed by the touch panel 22. At this time, an image of the soft key is displayed at a predetermined position on the display screen of the display 21.

  Note that an operation key different from the operation key group 3a can be provided at a position where the operation can be performed from the outside even when the second cabinet 2 is completely closed, for example, on the side surface of the first cabinet 1. In this way, even if the second cabinet 2 is completely closed, it is possible to perform a desired operation using such operation keys.

  FIG. 2 is a block diagram showing the overall configuration of the mobile phone. The cellular phone according to the present embodiment includes a CPU 100, a memory 200, a video encoder 301, a GPS module 302, a microphone 303, a voice encoder 304, a key input circuit 305, a communication module 306, and a backlight driving circuit in addition to the above-described components. 307, a key backlight 308, a video decoder 309, an audio decoder 310, a call speaker 311 and an external speaker 312.

  The camera module 11 has an image sensor such as a CCD. The camera module 11 digitizes the image signal output from the image sensor, performs various corrections such as gamma correction on the image signal, and outputs the image signal to the video encoder 301. The video encoder 301 encodes the image pickup signal from the camera module 11 and outputs the encoded signal to the CPU 100.

  The GPS module 302 measures a geographical current position such as longitude and latitude based on signals from a plurality of GPS satellites in the sky, and outputs the position information, that is, GPS information to the CPU 100.

  The microphone 303 converts the collected sound into a sound signal and outputs the sound signal to the sound encoder 304. The audio encoder 304 converts an analog audio signal from the microphone 303 into a digital audio signal, encodes the digital audio signal, and outputs it to the CPU 100.

  The key input circuit 305 outputs an input signal corresponding to each key to the CPU 100 when each key of the operation key group 3a is operated.

  The communication module 306 converts an audio signal, an image signal, a text signal, and the like from the CPU 100 into a radio signal and transmits it to the base station via the antenna 306a. In addition, the wireless signal received via the antenna 306a is converted into an audio signal, an image signal, a text signal, and the like and output to the CPU 100.

  The backlight drive circuit 307 supplies a voltage signal corresponding to the control signal from the CPU 100 to the key backlight 308 and the panel backlight 21b. The key backlight 308 is turned on by a voltage signal from the backlight driving circuit 307, and illuminates each key of the operation key group 3a. The panel backlight 21b is turned on by a voltage signal from the backlight driving circuit 307 and illuminates the liquid crystal panel 21a.

  The video decoder 309 converts the video signal from the CPU 100 into an analog or digital video signal that can be displayed on the liquid crystal panel 21a, and outputs it to the liquid crystal panel 21a. The liquid crystal panel 21a displays an image corresponding to the video signal on the display screen.

  The audio decoder 310 performs decoding processing on the audio signal from the CPU 100, further converts the audio signal into an analog audio signal, and outputs the analog audio signal to the call speaker 311. Also, the audio decoder 310 performs decoding processing on the sound signals of various notification sounds such as a ring tone and an alarm sound from the CPU 100, converts the sound signals into analog sound signals, and outputs the analog sound signals to the external speaker 312. The call speaker 311 reproduces the audio signal from the audio decoder 310 as audio. The external speaker 312 reproduces a ringtone from the audio decoder 310 and the like.

  The memory 200 includes a ROM and a RAM. The memory 200 stores a control program for giving a control function to the CPU 100. The memory 200 stores image data captured by the camera module 11, image data captured from the outside via the communication module 306, text data (mail data), and the like in a predetermined file format.

  The CPU 100 operates the camera module 11, the microphone 303, the communication module 306, the liquid crystal panel 21 a, the call speaker 311, the external speaker 312, and the like according to the control program based on the operation input signals from the key input circuit 305 and the touch sensor 22. As a result, various functions (applications) such as a call function and an e-mail function are executed.

  The CPU 100 includes a shooting control unit 101 and a setting processing unit 102. The photographing control unit 101 and the setting processing unit 102 are realized as software functions executed by the CPU 100.

  The shooting control unit 101 executes shooting processing using the camera module 11 and stores the shot image data in the memory 200. At this time, if the GPS automatic mode is set, GPS information is automatically acquired at the time of photographing and added to the photographed image data.

  The setting processing unit 102 executes an automatic mode setting process for setting to the GPS automatic mode. The setting processing unit 102 executes GPS exclusion setting processing. By executing the GPS exclusion setting process, the range of the place where GPS information is not added (exclusion area), the size of the exclusion area (gradual radius), and the like are set.

  First, the processing operation in the GPS exclusion setting process will be described. 3 and 4 are flowcharts of the GPS exclusion setting process.

  Referring to FIG. 3A, when the GPS exclusion setting item is selected from a predetermined setting menu displayed on the display 21, the setting processing unit 102 displays an exclusion setting screen on the display 21 (S101). . Three items of “exclusion area registration”, “exclusion radius setting”, and “exclusion area ON / OFF” are displayed on the display 21 (see screen 1 in FIG. 5).

  An item to be set is selected from the three items by the user. If “exclusion area registration” is selected (S102: YES), the setting processing unit 102 executes exclusion area registration processing (S104). If “exclude radius setting” is selected (S102: NO → S103: YES), an exclusion radius setting process is executed (S105), and if “exclude area ON / OFF” is selected (S103: NO). Then, the exclusion area ON / OFF setting process is executed (S106).

  FIG. 4 is a flowchart of the exclusion area registration process. FIG. 5 is a diagram illustrating a screen display example when the excluded area registration process is executed.

  Referring to FIG. 4, the setting processing unit 102 first displays a registration list screen on the display 21 (S201). On the display 21, the place name (home, company, etc.) of the exclusion area that has already been registered is displayed as a selection item, and a mark selected at the time of new registration is displayed as a selection item below (FIG. 5). Screen 2).

  When any item is selected (S202: YES), the setting processing unit 102 determines whether it is a new registration item (S203). If it is a new registration item (S203: YES), an acquisition method selection screen for selecting a GPS information acquisition method is displayed on the display 21 (S204). Three items of “register current location”, “quote GPS list”, and “quote address book” are displayed on the display 21 (see screen 3 in FIG. 5).

  When registering the current location as an excluded area, the user selects “Register Current Location”.

  When the item “register current location” is selected (S205: YES), the setting processing unit 102 activates the GPS module 302 and acquires GPS information of the current position from the GPS module 302 (S206). Note that the setting processing unit 102 causes the display 21 to display the GPS information during acquisition of GPS information (see screen 4 in FIG. 5). Further, when the acquisition of the GPS information is completed, the completion is displayed on the display 21 (see screen 5 in FIG. 5).

  Next, the setting processing unit 102 displays an input screen for inputting the location name of the acquired GPS information on the display 21 (S207: refer to screen 6 and screen 7 in FIG. 5). When the location name is input by the user and an input completion operation is performed (S208: YES), the acquired GPS information is registered in association with the location name as a new exclusion area (S209). Information on the exclusion area is stored in the memory 200. At this time, a registration list screen to which the newly registered place name is added is displayed on the display 21 (see screen 8 in FIG. 5).

  By the way, when the item “GPS list quotation” is selected on the acquisition method selection screen (S210: YES), a list of GPS information acquired in advance and stored in the memory 200 in correspondence with the place name ( GPS information to be registered as an excluded area is acquired from the GPS information list) (S211). Then, the acquired GPS information is registered as a new exclusion area (S209).

  On the other hand, when the item “citation of address book” is selected on the acquisition method selection screen (S210: NO), it is stored in the address book (address book table in the memory 200) corresponding to the name of the person. From the GPS information, GPS information to be registered as an excluded area is acquired (S212). Then, the acquired GPS information is registered as a new exclusion area (S209).

  If a location name that has already been registered is selected on the registration list screen, the setting processing unit 102 activates the GPS module 302 and acquires GPS information of the current position from the GPS module 302 (S213). . Then, the GPS information of the selected place name is updated to the newly acquired GPS information (S214).

  FIG. 3B is a flowchart of the exclusion radius setting process. FIG. 6 is a diagram illustrating a screen display example when the exclusion radius setting process is executed.

  Referring to FIG. 3B, when “exclude radius setting” is selected on the exclusion setting screen, the setting processing unit 102 causes the display 21 to display an input screen for inputting the exclusion radius (S301). : Refer to screen 2 and screen 3 in FIG. The exclusion radius indicates a range where GPS information is not added to the image data around the point registered as the exclusion area, that is, the size of the exclusion area. For example, if the exclusion radius is set to 800 m, the area with a radius of 800 m from the registration point becomes the exclusion area. For example, when a user registers his / her home in the exclusion area, the exclusion area can be set wider when not only the home and the vicinity thereof but also the town where he / she lives is not known to others.

  When a numerical value is input by the user and an input completion operation is performed (S302: YES), the setting processing unit 102 registers the input numerical value as an excluded radius (S303). The value of the exclusion radius is stored in the memory 200. At this time, the display 21 displays a notification indicating the size of the slow outside area (see screen 4 in FIG. 6).

  Here, when the exclusion radius is set, the exclusion radius is uniformly set for all the registered exclusion areas. However, a different exclusion radius may be set for each exclusion area. Further, whether to apply the exclusion radius may be set for each exclusion area.

  In addition, instead of displaying the exclusion radius in characters on the display 21 as in the screen 4 of FIG. 6, a map is displayed on the display 21 so as to distinguish the exclusion area from the other areas on the map. You may make it perform. In this case, for example, it is conceivable to display the exclusion area with a circle.

  FIG. 3C is a flowchart of the exclusion area ON / OFF setting process. FIG. 7 is a diagram illustrating a screen display example when the exclusion area ON / OFF setting process is executed.

  Referring to FIG. 3C, when “exclusion area ON / OFF” is selected on the exclusion setting screen, the setting processing unit 102 displays an input screen for performing ON / OFF setting of the exclusion area. 21 (S401: refer to screen 2 in FIG. 7).

  When the ON setting is selected by the user (S402: ON selection), the setting processing unit 102 sets the exclusion area to ON (S403). As a result, the exclusion area becomes valid, and it is determined whether or not the GPS information is within the exclusion area range in the imaging process described later.

  On the other hand, when the OFF setting is selected by the user (S402: OFF selection), the setting processing unit 102 sets the exclusion area to OFF (S404). As a result, the exclusion area becomes invalid, and it is not determined whether or not the GPS information is within the exclusion area range in the imaging process described later. When the ON setting or the OFF setting is performed, the setting result is displayed on the display 21 (see screen 3 and screen 4 in FIG. 7).

  In addition, when displaying on the display 21 that it was set to ON, you may make it display the map and show the place of an exclusion area on a map.

  Next, processing operations in the automatic mode setting process will be described. FIG. 8 is a flowchart of the automatic mode setting process. FIG. 9 is a diagram illustrating a screen display example when the automatic mode setting process is executed.

  Referring to FIG. 8, setting processing unit 102 displays an automatic mode setting screen for setting the GPS automatic mode when a GPS automatic setting item is selected from a predetermined setting menu displayed on display 21. (S501: see screen 1 in FIG. 9).

  When the ON setting is selected by the user (S502: ON selection), the setting processing unit 102 determines whether or not an exclusion area is registered (S503). If an exclusion area is registered (S503: YES), a list of exclusion areas (location names) is displayed on the display 21 (S504: see screen 2 in FIG. 9). On the other hand, if no exclusion area is registered (S503: NO), a message indicating that no exclusion area is registered is displayed on the display 21 (S505: see screen 3 in FIG. 9).

  Thus, when the GPS automatic mode is set, the registration status of the exclusion area is displayed. Thereby, since the user can confirm the registration status of the exclusion area, it is possible to prevent the GPS automatic mode from being set without registering the necessary exclusion area.

  If the user confirms the registration status of the outside area and an agreement operation is performed based on this (S506: YES), the setting processing unit 102 sets the GPS automatic mode (S507). At this time, the display 21 displays that the GPS automatic mode has been set (see screen 4 in FIG. 9).

  On the other hand, if the cancel operation is performed by the user because the necessary exclusion area is not registered (S507: NO → S508: YES), the setting processing unit 102 performs the process without setting the GPS automatic mode. finish.

  When the user selects OFF setting on the automatic mode setting screen (S502: OFF selection), the setting processing unit 102 cancels the GPS automatic mode (S509). At this time, the display 21 displays that the GPS automatic mode has been canceled (see screen 5 in FIG. 9).

  Note that the user can only confirm the registration status of the exclusion area on the screens 2 and 3 in FIG. 9, but may further change the confirmed registration status.

  FIG. 10 is a diagram showing a screen in this case. Here, operation buttons “delete”, “add”, and “OK” are added to the screens 2 and 3 in FIG. When the user selects “elementary school” on the screen 2 and operates the “delete” operation button, “elementary school” is deleted from the exclusion area as shown in the screen 4. Further, when the user operates the “add” operation button on the screen 3, the GPS information list described above is displayed as a selection candidate for the exclusion area as shown in the screen 5. In this screen, when the user selects “elementary school” and operates the “add” operation button, “elementary school” is added to the exclusion area as shown in screen 7.

  Next, the processing operation of the photographing process when the GPS automatic mode is set will be described. Here, it is assumed that the exclusion area registration has already been performed and the exclusion area is set to ON.

  FIG. 11 is a flowchart of the photographing process when the GPS automatic mode is set.

  Referring to FIG. 11, when the user performs an operation to activate the camera function, the operation control unit 101 activates the camera module 11 (S601). When the camera module 11 is activated, the video captured by the camera module 11 is displayed on the display 21 as a preview image.

  The imaging control unit 101 determines whether or not a shutter button (for example, the enter key 33) has been operated (S602). When the shutter button is operated, the photographing control unit 101 performs a photographing operation (S603). That is, the imaging control unit 101 temporarily stores the image data acquired when the shutter button is operated in the temporary storage area of the memory 200.

  Next, the imaging control unit 101 activates the GPS module 302 and acquires GPS information of the current position from the GPS module 302 (S604). Then, it is determined whether or not the acquired GPS information is within the range of the registered exclusion area (S605).

  At this time, if the acquired GPS information is not within the exclusion area (S605: NO), the imaging control unit 101 reads the temporarily stored image data and adds the acquired GPS information to the image data. And stored in the memory 200 (S606).

  On the other hand, if the acquired GPS information is within the exclusion area (S605: YES), the imaging control unit 101 reads the temporarily stored image data and adds the acquired GPS information to the image data. Without being stored in the memory 200 (S607).

  If an exclusion radius is set in the exclusion area, it is determined in S605 whether the current shooting position is within the exclusion radius. If no exclusion radius is set in the exclusion area, it is determined in S605 whether the current shooting position is within a predetermined distance (about 10 m) from the position registered in the exclusion area. The

  In this way, every time a photo is taken, GPS information is automatically acquired, and based on the determination whether the GPS information is within the exclusion area, image data with GPS information added or added The image data that is not stored is stored in the memory 200.

  Thus, when the user performs an operation to end the camera function (S608: YES), the imaging control unit 101 stops the camera module 11 (S609) and ends the imaging process.

  As described above, according to the present embodiment, if a place that is not desired to be disclosed, such as a home, is registered as an exclusion area, GPS information is not added to the image data even if camera shooting is performed in such a place. . Therefore, for example, even when an image taken by a user is uploaded to a homepage or the like and the image is associated with map information, it is possible to prevent others from knowing a place related to personal information, such as home, by mistake. Can do.

  Further, according to the present embodiment, since the user can set a place (GPS information) as an exclusion area, the exclusion area can be set according to the circumstances of the individual user, which is easy to use.

  Furthermore, according to the present embodiment, since the user can set the size of the exclusion area, the exclusion area can be set according to the circumstances of the individual user, and the usability is further improved.

  Furthermore, according to the present embodiment, the user can set whether to exclude or invalidate the exclusion area. Accordingly, for example, when shooting is performed near a home or the like and included in the exclusion area, and GPS information is to be added to the image data, the exclusion area can be temporarily invalidated. Therefore, usability is further improved.

<Modification 1>
FIG. 12A is a flowchart of the imaging process when the GPS automatic mode is set according to the first modification. FIG. 12B is a diagram illustrating a display example of a confirmation screen displayed in the photographing process of FIG. In the flowchart of FIG. 12A, for the sake of convenience, processing different from that of the above-described embodiment and partial processing before and after the processing are shown.

  In the present modification example, when the shooting control unit 101 determines that the GPS information acquired in step S604 is within the exclusion area (S605: YES), the shooting control unit 101 displays a confirmation screen on the display 21. For example, as shown in FIG. 12B, the confirmation screen includes a display that the acquired GPS information is not added to the image data, and a display that allows the user to select whether or not to agree.

  If the user agrees, that is, if “Yes” on the confirmation screen is selected (S611: YES), the imaging control unit 101 stores the image data in the memory 200 without adding GPS information (S607). On the other hand, if the user does not agree, that is, if “No” on the confirmation screen is selected (S611: NO), the imaging control unit 101 adds GPS information and stores the image data in the memory 200 (S606). ).

  The place where the user photographed happened to be near the home or the like and was in the excluded area. However, there is a case where it is desired to add GPS information to the image data of this place. In such a case, if the user does not agree, GPS information can be added even when shooting in the exclusion area.

  Therefore, even when shooting in the excluded area, if necessary, GPS information can be easily added to the image data, improving usability.

<Modification 2>
In the above embodiment, if the exclusion area is registered in advance and the acquired GPS information is within the exclusion area, the GPS information is not added to the image data. However, the present invention is not limited to this, and as will be described below, it is possible to prevent GPS information from being added to the image data if the exclusion time zone is registered in advance and the time when the image is captured is within the exclusion time zone.

  FIG. 13 is a flowchart of the GPS exclusion setting process according to the second modification. FIG. 13A is a flowchart of the main process in the GPS exclusion setting process. FIG. 13B is a flowchart of the exclusion timer setting process. FIG. 14 is a diagram illustrating a screen display example when the exclusion timer setting process is executed.

  In the present modification example, an “exclusion timer setting” item is added to the items on the exclusion setting screen (see screen 1 in FIG. 14). Then, as illustrated in FIG. 13A, if “exclusion timer setting” is selected (S107: NO), the setting processing unit 102 executes the exclusion timer setting process (S108).

  With reference to FIG. 13B, the processing operation of the exclusion timer setting process will be described.

  First, the setting processing unit 102 causes the display 21 to display an ON / OFF setting screen for setting whether the exclusion timer is set (turned on) or canceled (turned off) (S701: FIG. 14 screen 2).

  When the ON setting is selected by the user (S702: ON selection), the setting processing unit 102 displays an input screen for inputting the exclusion time zone on the display 21 (S703: see screen 3 and screen 4 in FIG. 14). ). Then, when the user inputs a time zone (start time and end time) and performs an input completion operation (S704: YES), the input time zone is registered as an excluded time zone (S705). The value of the exclusion time zone is stored in the memory 200. At this time, the display 21 displays that the GPS information is not added to the image data during the set time zone (see screen 5 in FIG. 14).

  When the user selects OFF setting on the ON / OFF setting screen (S702: OFF selection), the setting processing unit 102 cancels the setting of the exclusion timer (S706). In this case, it is not determined whether it is an excluded time zone in the photographing process described later.

  FIG. 15 is a flowchart of the photographing process when the GPS automatic mode is set according to the second modification. In the flowchart of FIG. 15, for the sake of convenience, processing different from that of the above embodiment and partial processing before and after the processing are shown.

  In the present modification example, when the GPS information of the current position is acquired (S604), the imaging control unit 101 determines whether or not the imaging time is in the registered exclusion time zone (S612). If the shooting time is in the excluded time zone (S612: YES), the image data is stored in the memory 200 without adding the GPS information regardless of whether the GPS information is in the excluded area (S607). .

  As described above, according to the present modification example, if a time zone in a place where the user does not want to be disclosed such as a home is registered as an excluded time zone, the image data can be obtained even if the camera shooting is performed in such a location. GPS information is not added. Therefore, even when an image taken by a user is uploaded to a home page or the like and the image is associated with map information, it is possible to prevent others from knowing a place related to personal information such as a home by mistake. .

  Note that the configuration of this modification example can also be applied to the configuration of the modification example 1 described above. FIG. 16A is a flowchart of a photographing process when the configuration of the second modification is applied to the configuration of the first modification. FIG. 16B is a diagram illustrating a display example of a confirmation screen displayed in the photographing process of FIG. In the flowchart of FIG. 16A, for the sake of convenience, processing different from that in the above-described embodiment and modification example 1 and partial processing before and after the processing are shown.

  Referring to FIG. 16, if the shooting control unit 101 determines that the GPS information acquired in step S604 is an excluded time zone (S612: YES), the shooting control unit 101 displays a confirmation screen on the display 21 (S613). For example, as shown in FIG. 16B, the confirmation screen includes a display that the acquired GPS information is not added to the image data and a display that allows the user to select whether or not to agree.

  If the user agrees, that is, if “Yes” is selected on the confirmation screen (S614: YES), the imaging control unit 101 stores the image data in the memory 200 without adding GPS information (S607). On the other hand, if the user does not agree, that is, if “No” is selected on the confirmation screen (S614: NO), the imaging control unit 101 proceeds to the processing of S605 and determines whether or not the GPS information is within the exclusion area. Judgment is made.

  In this way, GPS information can be easily added to the image data, if necessary, even when shooting in the excluded time zone, improving usability.

  In this modification, not only the exclusion time zone is determined but also the exclusion area is determined. However, only the exclusion time zone may be determined.

<Modification 3>
FIG. 17 is a flowchart of the imaging process when the GPS automatic mode is set according to the third modification.

  In the above embodiment, if it is determined that the acquired GPS information is within the exclusion area, the GPS information is not added to the image data.

  In contrast, in the present modification example, as illustrated in FIG. 17, when the imaging control unit 101 determines that the acquired GPS information is within the exclusion area (S605: YES), the alternative GPS information is added to the image data. Then, it is stored in the memory 200 (S615).

  Here, the substitute GPS information is approximate position information that replaces the acquired GPS information. For example, the alternative GPS information is shifted from a point of the acquired GPS information in a specific direction (such as the south direction) and is out of the excluded area. However, the position information can be used.

  With such a configuration, for example, when an image taken by a user is uploaded to a home page or the like and the image is associated with map information, the exact shooting location is not known and the approximate shooting location is displayed on the map. Can be displayed.

  Note that this modification example can be applied to the configurations of Modification Examples 1 and 2. In this case, the process in step S607 in FIGS. 12, 15, and 16 is replaced with the process in step S615 in FIG.

<Others>
Various modifications can be made in addition to the forms shown in the above embodiment and modification examples.

  For example, in the embodiment and the modification described above, the configuration in which GPS information is added to image data captured by the camera module 11 when the image data is stored in the memory 200 has been described. However, the GPS information can be added to the image data already stored in the memory 200. In this case, time information is added to the image data at the time of shooting. Further, time information is added to the GPS information at the time of acquisition. Thereby, GPS information of the acquisition time that is consistent with the shooting time is added to the image data. At this time, it is determined whether or not the GPS information is within the exclusion area. If the GPS information is within the exclusion area, the GPS information is not added to the corresponding image data. Alternatively, it is determined whether or not the shooting time or the acquisition time is an excluded time zone, and if it is an excluded time zone, the GPS information is not added to the corresponding image data.

  In addition, when adding GPS information to already stored image data, the mobile phone may not have a built-in GPS module, and GPS information may be acquired from a separately prepared GPS device. In this case, the mobile phone is provided with an interface unit that acquires GPS information from the GPS device, and this interface unit corresponds to the position acquisition unit of the present invention.

  In the above embodiment, when the GPS automatic mode is set, if no exclusion area is registered, that fact is displayed on the display 21. However, as a countermeasure when no exclusion area is registered, the following can be performed.

  That is, the setting processing unit 102 acquires GPS information every predetermined time by the GPS module 302, and stores the GPS information that has not changed for the longest time in the memory 200 as GPS information of registration candidates. The user is considered to be at home or at the office for the longest time, and these locations may be subject to exclusion areas.

  Therefore, when the exclusion area is not registered at all, the setting processing unit 102 displays the GPS information of the registration candidate on the display 21 and informs the user whether it can be registered as the exclusion area. At this time, even if the latitude and longitude are displayed on the display 21, it is difficult for the user to understand where the place is. Therefore, it is desirable that the setting processing unit 102 be configured to download the map information of the location corresponding to the GPS information of the GPS registration candidate from the site where the map information can be obtained and display it on the display 21.

  In this way, if candidate GPS information is displayed and the consent of registration is obtained by the user, the setting processing unit 102 registers the GPS information as an excluded area.

  With such a configuration, at the time of setting the GPS automatic mode, even if no exclusion area is registered, the minimum registration can be easily performed.

  If no exclusion area is set when the GPS automatic mode is set, an exclusion area registration process is automatically executed, and a registration list screen (see screen 2 in FIG. 5) is displayed on the display 21. May be. In this case, only a new registration mark is displayed on the screen.

  Furthermore, the storage form of the GPS information associated with the image data can be changed as appropriate. In the above embodiment, GPS information is added to the image data and stored in the memory 200. In this case, the GPS information is included in a predetermined storage area (for example, an Exif area for a JPEG file) in an image data file (for example, a JPEG file) and recorded in the memory 200. Instead, a GPS information file is created separately from the image data file, the image data in the image data file is associated with the GPS information in the GPS information file, and both files are recorded in the memory 200. May be. In short, the GPS information (position information) may be stored in the memory in association with the image data.

  In the above embodiment, when the position specified by the GPS information is within the exclusion area, it is prohibited to add the GPS information to the image data. However, the position specified by the GPS information is not included in the exclusion area. The GPS information is added to or associated with the image data and stored, and the display based on the association between the image based on the image data and the position information of the image is prohibited at a later stage. Also good. In this case, for example, if the position defined by the GPS information is within the exclusion area, the prohibition flag is set in association with the GPS information and the image data. For example, for an image with a prohibition flag set, control is performed such that (1) it cannot be uploaded to the web server, (2) it can be uploaded to the web server, but the association with the GPS information is removed. Is called. In this way, it is possible to prevent a position that is not desired to be known from being acquired or viewed by another person. This configuration can also be applied in the case of the second modification.

  Furthermore, in the above embodiment, the present invention is applied to a so-called slide type mobile phone. However, the present invention is not limited to this, and the present invention may be applied to a so-called foldable mobile phone.

  Furthermore, the mobile terminal device of the present invention is not limited to a mobile phone, and may be a PDA (Personal Digital Assistant) or the like.

  In addition, the embodiment of the present invention can be variously modified as appropriate within the scope of the technical idea shown in the claims.
