In the main operation unit 120 and the sub operation unit 130, operation keys other than the power off button 122B and the power on button 122C. Are collectively referred to as “input keys”.

  In the mobile phone 100 of the present embodiment, the sub camera 142 is provided in the vicinity of the main display 150, and the main camera 140 described later is provided on the outer surface side of the first housing 104 (the back side of the surface on which the main display 150 is provided). However, the portable information device according to the present invention is not limited to such a configuration, and the installation positions of the sub camera 142 and the main camera 140 and whether or not they are mounted are arbitrary. .

FIG. 3 is a functional block diagram of the mobile phone 100.
Referring to FIG. 3, antenna 108 of mobile phone 100 transmits and receives voice data, character data, image data, and the like when performing wireless communication with a base station via radio waves. The wireless unit 4 demodulates data received from the base station via the antenna 108 at the time of reception and sends it to the main control unit 10 via the communication control unit 6, and at the time of transmission from the main control unit 10 to the communication control unit 6. Audio data, character data such as e-mail, image data attached to e-mail, etc. are sent from the antenna 108 based on a predetermined protocol.

  The main control unit 10 controls the operation of each unit of the mobile phone 100, and a ROM (Read Only Memory) 8 stores a program for the operation of the main control unit 10. A RAM (Random Access Memory) 30 functions as a memory for temporary storage such as when a program in the ROM 8 is expanded or used as a working memory when the main control unit 10 operates. The non-volatile memory 32 is composed of, for example, a flash memory, and as will be described later, a state function table 34 in which each operation state of the mobile phone 100 is associated with an operable function, transmission / reception history data 36, The dummy state display data 38 and the like storing data for displaying in the dummy power-off state and the dummy state-on state are stored. Further, the nonvolatile memory 32 also stores flag information indicating the current operation state that is referred to by the main control unit 10.

  The imaging unit 20 includes a camera 140 and a sub camera 142. The image processing unit 22 includes an amplification unit, an A / D (analog / digital) conversion unit, and a signal processing unit. The amplifying unit amplifies an electrical signal corresponding to an image signal such as RGB sent from the imaging unit 20, and sends the amplified signal to the A / D conversion unit. The A / D conversion unit converts an electrical signal (analog) corresponding to the image signal converted by the amplification unit into a digital signal, outputs image data, and sends the image data to the signal processing unit. The signal processing unit performs signal processing such as pixel interpolation processing on the image data sent from the A / D conversion unit. Further, the signal processing unit sends the image data subjected to the signal processing to the RAM 30 based on the control signal sent from the main control unit 10.

  The image memory area in the RAM 30 temporarily stores image data continuously sent from the signal processing unit. For example, temporally old image data is temporarily stored by deleting or overwriting the newest image data. In addition, in the image memory area in the RAM 30, not only image data from the imaging unit 20 but also image data to be displayed is read from, for example, the nonvolatile memory 32 under the control of the main control unit 10. Sometimes written.

  The main control unit 10 transmits a control signal to the display driver unit 42 and transmits image data stored in an image memory area in the RAM 30 to the display driver unit 42. The display driver unit 42 applies a driving voltage to each pixel electrode of the main screen 150 or the sub screen 160 according to image data to be displayed on the main screen 150 or the sub screen 160.

  The main backlight 152 and the sub backlight 162 are configured by light emitting diodes or the like that are light emitting elements, and illuminate the main screen 150 or the sub screen 160 to increase the luminance. Control of turning on and off the main backlight 152 and sub-backlight 162 (control of power supply on / off) and brightness adjustment are performed by the main control unit 10. Further, the main backlight 152 and the sub backlight 162 can be controlled independently. When the image is displayed on the main screen 150, the main backlight 152 is displayed on the sub screen 160. In this case, the sub-backlight 160 is controlled to be turned on.

  As described above with reference to FIGS. 1 and 2, the operation unit 12 includes the input key 14, the power-off button 122 </ b> B, and the power-on button 122 </ b> C.

  The microphone 26 converts the user's voice into an electric signal and gives it to the main control unit 10 during a call, and the main control unit 10 gives this electric signal to the communication control unit 6 as voice data. On the other hand, the speaker 28 converts the electric signal of the voice given through the communication control unit 6 and the main control unit 10 into a voice during a call, and reproduces the music data stored in the nonvolatile memory 32. Etc. are also output.

  The position information detection unit 50 receives, for example, a well-known GPS (Global Positioning System) signal and acquires the position information of the mobile phone 100.

  The open / close detection unit 52 is detection means for detecting whether or not the mobile phone 1 is folded. A detection switch (not shown) is provided inside the hinge, and a signal is sent to the main control unit 10 according to the open / closed state, and the main control unit 10 determines whether the cellular phone 100 is folded. In FIG. 1 to FIG. 2, since the mobile phone 100 has a foldable shape, such an open / close detection is performed. However, for example, the mobile phone 100 has another mechanism such as a slide type. Thus, in the case where the user makes a call after changing the form that the user normally carries around, the form change detection that detects such a change in form instead of the open / close detection unit 52 Parts are provided.

  The power supply unit 54 includes a battery (not shown) and supplies power to each unit of the mobile phone 100. On / off of power supply to each part of the mobile phone 100 is controlled by the main control unit 10. However, the power supply itself to the main control unit 10 is started by operating the power-on button 122C.

  FIG. 4 is a conceptual diagram showing a state in which the mobile phone 100 and the mobile phone 102 exchange mail.

  Referring to FIG. 4, mobile phone 100 is connected to the Internet network via base station BS1, while mobile phone 102 is connected to the Internet network via base station BS2 to exchange mail with each other. be able to. In addition, the cellular phone 100 receives a positioning signal from a GPS satellite and acquires its own position information.

  As will be described later, for example, when the address of the mobile phone 102 is registered in advance in the nonvolatile memory 32 of the mobile phone 100 as a notification destination, in the “dummy power off state”, the mobile phone 102 100 notifies the mobile phone 102 of its own location information by e-mail.

[Power control of mobile phone 100]
Hereinafter, power control of the mobile phone 100 will be described.

  The mobile phone 100 of the present invention is a portable communication terminal device having a communication function with the power-off button 122B and the power-on button 122C. When only the power-off button 122B is operated, the surface is viewed from the user. Although the power supply is turned off, the main control unit 10, the radio unit 4, the communication control unit 6, the ROM 8, the RAM 30, and the position information detection unit 50 are actually temporarily stopped ("dummy power supply" Off state)). On the other hand, when the user is recognized as an authorized user by the personal authentication procedure, when the power off button 122B is operated, the power supply from the power supply unit 54 to the mobile phone 100 is completely stopped. Become. When the power-on button 122C is operated in this stopped state, power supply to the main control unit 10 is started.

[Regular power off processing]
Hereinafter, first, an operation for properly turning off the power from the standby state of the mobile phone 100 to enter the stopped state will be described.

FIG. 5 is a flowchart for explaining such a regular power-off operation.
First, in the standby state (S100), the main control unit 10 determines whether the “power off menu” has been called by the user's operation, and a transition is made to the power off menu mode until there is a call (S102). ).

  When the main control unit 10 determines that an operation to enter the “power off menu” has been performed (S104), and subsequently authentication information is input, for example, a password is input (S104), the user is authenticated by the authentication process. It is determined whether the user is a legitimate user (S106). If the user is not authenticated, the process returns to step S102.

  On the other hand, if the main control unit 10 determines that the user is a legitimate user by the authentication process (Y in S106) and then determines that the power-off button 122B is operated, the main control unit 10 Is instructed to completely stop the power supply from the power supply unit 54 to the mobile phone 100 (S110), and the process ends (S112).

  FIG. 6 is a diagram illustrating an example of a state function table of “normal standby state” and “regular power-off state” included in the state function table 34 illustrated in FIG. 3.

  The main control unit 10 refers to the state function table to determine whether or not such operation is effective in the current operation state when a user operation is performed, and is effective (available). If it is determined that the process is invalid (unusable), the process corresponding to the operation is not performed.

  FIG. 6A is a “function table in a normal standby state”. In the normal standby state, “power operation (operation of the power-off button 122B and power-on button 122C)”, “key input operation (power supply) (Except key operation) "," (notification of incoming calls and incoming mails by sound) "," display processing "," (call) outgoing "," (call) incoming "," send mail " ”,“ Mail reception ”,“ Camera operation ”,“ Reference to phone book ”,“ Query mail box ”,“ Reference to call history ”,“ Operation of data file ”,“ Acquisition of location information ”,“ (clock All of the additional functions (such as calculator, electronic money, etc.) are available.

  Note that “referring to the phone book” refers to referring to the contents of the regular phone book stored in the non-volatile memory 32 (referring to the contents and making a one-touch call based on the contents) and registering to the regular phone book. means. The reference to the contents of the regular phone book and the registration process to the regular phone book may be permitted only when authenticated as a regular user by personal authentication such as password entry. .

  On the other hand, FIG. 6B is a “functional power-off state function table”. In the normal power-off state (mainly stopped state), only “power operation” can be used. Or, the processing is in an unusable state.

(Authentication process for regular power-off process)
FIG. 7 is a diagram showing a display example of the main screen 150 in the process of inputting authentication information for personal authentication in S102 to S106 of FIG.

  First, as shown in FIG. 7A, the user generally calls a main menu screen listing the operations of the mobile phone 100. Subsequently, in FIG. 7A, when the “management function” is selected by the user, the menu screen is shifted to the next lower level in FIG. 7B. Further, when the user selects “power control” on the screen of FIG. 7B, the screen shifts to a screen for prompting the input of a password as shown in FIG. 7C.

  Here, if the entered password matches that registered in advance, the main control unit 10 authenticates the user as a legitimate user.

  As described above, if the personal authentication input screen in step S104 is placed in a menu deeper than the main menu, it is difficult for non-regular users to find a process for regular power-off. Even if it is necessary to input such authentication information, it is difficult for non-regular users to notice.

  In FIG. 7C, the individual is authenticated by inputting the password. However, for example, when the state is changed from FIG. 7B to FIG. 7C, the password is not entered. Alternatively, a method such as biometric authentication that can identify an individual may be used. For example, in a scene where authentication is required, the camera may be automatically activated and so-called “face authentication” may be performed in which authentication is performed based on face image information. Alternatively, as another personal authentication method, a fingerprint sensor may be provided in the mobile phone 100 to perform fingerprint authentication. Others such as iris authentication and a part or the whole of familiar things such as body, clothes, belongings may be authenticated by image data obtained by photographing with a camera.

  In the case of this fingerprint authentication, a fingerprint sensor is provided on the power-off button 122B itself, a message prompting the user to operate the power-off button 122B is displayed on the screen of FIG. 7C, and the power-off button 122B. The fingerprint may be automatically detected by the user pressing the button.

  FIG. 8 is a diagram showing a display example of the main screen 150 in another method of personal authentication processing.

  In FIG. 8, by selecting a combination of image data registered in advance in the terminal, personal authentication is performed depending on whether the combination matches the registered combination.

  That is, first, as shown in FIG. 8A, the user generally calls a main menu screen listing the operations of the mobile phone 100. Subsequently, in FIG. 8A, when the user selects “library”, the screen shifts to the menu screen of the next lower level in FIG. 8B. Further, when the user selects “Graphic Library” on the screen of FIG. 8B, the screen shifts to a thumbnail display screen as shown in FIG. As shown in FIG. 8C, the user selects three images from thumbnails arranged in 3 × 3, for example. In FIG. 8C, the selected image is displayed surrounded by a frame.

  Here, if the combination of the selected images matches the combination registered in advance, the main control unit 10 authenticates the user as a legitimate user. In the thumbnail display of FIG. 8C, the nine registered images may be always displayed at the same position, but the display position is randomly changed each time the screen of FIG. 8C is called. It is good to do.

[Dummy power off process]
Next, a description will be given of an operation in which only the power-off button 122B is operated from the standby state of the mobile phone 100 to enter the dummy power-off state.

FIG. 9 is a flowchart for explaining such a dummy power-off operation.
First, in the standby state (S200), the main control unit 10 determines whether or not the “power off button 122B” is operated by the user's operation (S202), and the dummy power off state until the power off button 122B is operated. The transition to is in a waiting state (S202).

  If the main control unit 10 determines that the power-off button 122B has been operated, the main control unit 10 performs a dummy power-off process (S204), and the process ends (S206). Here, the regular power-off process described in FIG. 5 and the dummy power-off process in FIG. 9 are in a standby state in parallel in the standby state.

  FIG. 10 is a diagram illustrating an example of a state function table of “key lock state” and “dummy power-off state” included in the state function table 34 illustrated in FIG. 3.

  In the state function table of FIG. 10, there is a state that limited use is possible, in addition to the states that can be used and cannot be used.

  FIG. 10C is a “function table in the key lock state”. In the key lock state, “power operation (operation of the power off button 122B and power on button 122C)”, “key input operation (operation of the power key). ”)”, “(Notification of incoming calls and incoming emails by sound)”, “display processing”, “(incoming call)”, “mail received” "Call (call)", "Send mail", "Camera operation", "Browsing phone book", "Mail box inquiry", "Call history browsing", "Data file operation" cannot be used It has become.

  On the other hand, for “acquisition of position information”, position information is acquired by receiving a GPS signal, but is not displayed on the display screen. As for the position information, it is also permitted that a device previously permitted from the outside of the mobile phone 100 accesses the outside wirelessly to acquire the position information.

  “Additional functions (such as a clock, a calculator, electronic money)” are in a limited usable state where only electronic money can be processed. However, among “additional functions (such as clock, calculator, electronic money)”, “additional functions about electronic money” can be used when dummy power is off to prevent unauthorized use of electronic money. It is not always necessary.

  On the other hand, FIG. 10D is a “dummy power-off state function table”. In the dummy power-off state (temporary stop state), only “power operation” can be used. Operation (except power key operation) ”,“ Notification processing (notifying incoming calls or incoming mails by sound, etc.) ”,“ Display processing ”,“ Calling (call) ”,“ Camera operation ”,“ Phonebook ” "Reference", "Mail BOX inquiry", "Call history reference", "Data file operation", and "Additional functions (clock, calculator, electronic money, etc.)" are unavailable. Yes. In addition, “mail transmission” is in a limited usable state in which an operation for periodic position information transmission processing by presetting is possible. On the other hand, “incoming call” and “mail reception” are in a state of limited use in which these processes are performed but no notification is given. Furthermore, “acquisition of location information” is in a limited useable state for periodic location information acquisition by presetting.

(Position information notification from dummy power off)
FIG. 11 is a flowchart for explaining the position information notification process in the dummy power-off state.

  That is, the cellular phone 100 uses the location information detection unit 50 that is functioning even in the dummy power-off state, the mail transmission function, the voice synthesis on the telephone, and the like to obtain the communication destination registered in advance as needed. Send the location information.

  Referring to FIG. 11, when the main control unit 10 determines that a certain time has elapsed after the dummy power-off state (S300), the position information detection unit 50 is controlled. When the current position information is acquired and the acquisition is completed (S304), the acquired position information is transmitted by e-mail to a communication destination registered in advance in the nonvolatile memory 32 (S306). Note that when the process is completed upon completion of step S306 (S308), the process returns to step S302 again.

  In such communication of position information, it is assumed that no output is given to the outside of the mobile phone as a notification of appearance or sound.

(Incoming call processing with dummy power off)
FIG. 12 is a flowchart for explaining the incoming call processing in the dummy power-off state.

  When calling processing is performed from the calling terminal to the mobile phone 100 (S500), in the mobile phone 100 that is the called terminal, the main control unit 10 determines whether or not the dummy power supply is currently off. (S502).

  When the main control unit 10 determines that the dummy power supply is off, a predetermined area in the non-volatile memory 32 with the telephone number of the incoming call side and the incoming call date and time as the transmission / reception history data 36 without notifying the outside of the incoming call. To record.

  Note that when returning to the normal state and referring to transmission / reception history data, the display color may be changed or marked so that the history in the temporary stop state can be understood.

  On the other hand, if the main control unit 10 determines in step S502 that the dummy power supply is not turned off, the incoming call is notified to the outside by sound or display (S506), and response processing is performed according to the user's operation. (S508).

For example, when the calling party performs a disconnection process (S510), the communication is terminated.
(Screen display when regular power off and dummy power off)
Generally, when a power-off operation is performed, a message screen is displayed before the display of the display screen is finished.

  As the message screen at this time, different message screens are registered in the nonvolatile memory 32 in advance when the regular power is turned off and when the dummy power is turned off, and when the power is turned off, the regular power off state and the dummy power off are performed. It may be made possible to distinguish which state of the transition to. In this case, a legitimate user who knows that the screen display is different in these cases can know which state the transition is to.

  Further, regardless of the message, it may be possible to distinguish which state is changed by sound, emission color, pattern, vibration or the like.

(Other example 1 of transition to dummy power supply state)
In the above description, it has been described that the process of shifting to the “dummy power-off state” is performed simply by operating the power-off button 122B.

  However, when the power off button 122B is simply operated, the main control unit 10 once enters a standby state, and is in a state equivalent to the normal power off state, except that the timer counts time. However, a transition to the dummy power-off state may be made after a certain time.

  In this way, for a certain period immediately after the power off button 122B is operated, if the mobile phone 100 is in a regular power off state, for example, by detection of radio waves output from the mobile phone 100 from the outside. It is impossible to know whether there is a dummy power-off state.

(Other example 2 of transition to dummy power supply state)
FIG. 13 is a flowchart showing another example of the transition to the dummy power-off state.

  Referring to FIG. 13, in the mobile phone 1000, in the standby state (S400), when the power off button 122B is simply operated (S402), the main control unit 10 temporarily enters the standby state and the open / close detection unit A state equivalent to the normal power-off state is obtained except that the detection process 52 is performed (S404). Subsequently, when a change in the shape of the terminal is detected by the open / close detection unit 52 (S406), after a predetermined time elapses (S408), a transition to the dummy power-off state is made (S410). That is, the shape change after the operation of the power-off button 122B is recognized as a physical switch, and a transition to the dummy power-off state is made after a certain time from the shape change.

  The change in the shape of the terminal may be a change in shape by another mechanism such as a slide type.

(Return from dummy power-off state)
The authorized user may be able to register the return condition from the dummy power-off state in the nonvolatile memory 32 in advance.

  For example, at a location registered in advance, registration to enter the normal standby mode from the dummy power-off is registered, and the main control unit 10 performs a return process based on this condition. At this time, whether or not the mobile phone 100 currently exists at the registered position may be based on a detection result of the location information detection unit 50. For example, the mobile phone 100 has a function of receiving a signal from a wireless tag. If it is possible to receive the registered location information obtained as a result of detecting the signal from the wireless tag that can be installed in a predetermined place and transmit the location information there It is good.

  Alternatively, as shown in FIG. 14, when the mobile phone 100 is placed in the charger 300, the main control unit 10 performs authentication with the charger, and when placed in a pre-registered charger, the dummy power source It is also possible to return to the normal standby mode from the off state.

  In addition, as an authentication method, authentication information input from an authentication information input device, for example, biometric information such as a password or a fingerprint may be used, and when such authentication is successful, it may be restored. .

[Control of transition to dummy power-on state]
In the above description, the control for transitioning from the standby state to the dummy power-off state has been described.

  In the following, a description will be given of control for shifting to the dummy power-on state when the power-on button 122C is operated in the dummy power-off state.

  This is because, for example, it is necessary to permit only a limited function even if it appears to have shifted to the power-on state in appearance, except for an authorized user.

  FIG. 15 is a flowchart for explaining control of transition to the dummy power-on state.

  Referring to FIG. 15, when the power-on button 122C is pressed in the dummy power-off state (S600) (S602), the state transits to the dummy power-on state (S604), and the referenceable data is stored in the nonvolatile memory 32. Are limited to the dummy state history data 37 and the dummy state display data 38.

  In other words, since the information (phone book, image data, etc.) stored in the terminal can access only dummy information, telephone and e-mail transmission can only be made based on the directly entered destination or dummy telephone book. Become.

  FIG. 16 is a “dummy power-on state function table”. In the dummy power-on state, “power operation”, “key input operation (excluding power key operation)”, “(incoming call, incoming mail, etc.) Notification process (notified by sound etc.) "," Display process "," Outgoing call "," Incoming call "," Send mail "," Receive mail "," Camera operation "," Acquire location information " ”Is available, but“ Additional functions (such as clock, calculator, electronic money) ”are available,“ reference to phone book ”,“ query mail box ”,“ reference call history ”,“ data file operation ” ", The dummy state history data 37 and the dummy state display data 38 in the nonvolatile memory 32 are displayed. For this reason, electronic money and the like cannot be actually used by setting the apparent balance to zero.

FIG. 17 is a flowchart for explaining the incoming call processing in the dummy power-on state.
Referring to FIG. 17, in the dummy power-on state (S700), when a call or mail arrives (S702), main controller 10 stores the incoming call history information as dummy state history data in nonvolatile memory 32. (S704) A notification that there is an incoming call is made (S706).

FIG. 18 is a flowchart for explaining the transmission process in the dummy power-on state.
Referring to FIG. 18, first, in the dummy power-on state (S800), when processing for outgoing is performed, main control unit 10 determines the content of outgoing (S802).

  If the content of outgoing call is outgoing mail, when a destination address is input by the user, a contact address previously registered in the nonvolatile memory 32 as a blind carbon copy (BCC) is added to the mail. . However, the contents of the destination of this BCC are not displayed on the display, and are not displayed on the destination (S806). After that, the main control unit 10 performs a transmission process (S808), writes a transmission history as the dummy state history storage data 27 (S810), and the process ends (S812). Although the communication history to the destination is written as the dummy state history storage data 27, the contact information registered in the nonvolatile memory 32 in advance is written to the dummy state history storage data 27. Absent.

  On the other hand, when the call content is a phone call, when the telephone number of the call destination is input by the user (S824), the main control unit 10 performs a call process (S826) and sends the dummy state history storage data 27 as a call. The history is written (S828), and the process ends (S830).

  In addition, as described below, in the dummy power-on state, the telephone call restriction may be performed. In other words, the control may be performed such that 1) the dial lock is activated and the call cannot be made, 2) the call is restricted to the direct input depending on the time or the number of times, and the 3) the direct input is applied even if the input is made. .

  With the configuration and control as described above, in the portable information device, when the power is turned off by an unauthorized process, the state transits to the dummy power-off state, and it looks as if the power is on. appear. However, since the location can be specified by operating the position information detection function or the communication function, it is possible to track a portable information device that has been used illegally.

  In addition, in the mobile phone, a mobile terminal equipped with a SIM (Subscriber Identity Module) card or UIM (User Identity Module) card function exists at this position. In this case, when the card is removed from the SIM card or the mobile terminal equipped with the UIM card, the dummy power supply may be kept off or the main power supply may be turned off.

  Alternatively, when replacing the dummy power OFF, the SIM card or UIM card cannot be replaced or invalidated with the dummy power OFF. It may not be able to be replaced normally only when the power is turned off.

  In addition, when replacing (done) with the dummy power off, if the SIM card or UIM card is replaced with the dummy power off, the power may be switched to the off state. In this case, a normal standby state may be entered, or a dummy power source may be turned on.

  As described above, when the normal or dummy power supply is turned on, the dummy phone book may be displayed, or the replaced SIM card (or UIM card) may be displayed. .

  If the data stored in the SIM card is normally displayed, the telephone number may be allowed only in the telephone directory stored on the SIM card.

  Further, in a terminal that is used with a SIM card attached, the authentication information may be on the SIM card or on the terminal itself.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
