Japanese Patent Laid-Open No. 2006-060685

  The function for preventing peeping by a third party in a conventional mobile terminal device is to perform the security lock function because the user performs a security lock by performing a key operation on the menu screen of the mobile terminal device. Very troublesome. In addition, since the security lock is performed by a user's manual operation, the security lock may be forgotten when the personal information needs to be protected. For this reason, the conventional peeping prevention function has many problems in actual use, which has been a factor of reducing the usage rate of the user using this function.

  In view of such a problem, the present invention provides a portable terminal portable terminal that can automatically switch to a monitoring mode that avoids a peeping action of a portable terminal device by a third party and cancels the monitoring mode automatically.

Determining means for determining whether or not the mobile terminal device is in a predetermined state to switch the operation mode to the monitoring mode; and when the mobile terminal device is in the predetermined state, the operation mode of the mobile terminal device is changed to the monitoring mode. Switching means for switching.

  The portable terminal device according to the present invention determines whether or not the portable terminal device is in a state satisfying a predetermined condition from information on the surrounding state of the portable terminal device detected by the detecting means, and sets the operation mode to the monitoring mode. Switch to. With this configuration, the portable terminal device according to the present invention can omit or simplify an operation that the user has to perform in order to shift to the monitoring mode.

  In the mobile terminal device according to another aspect of the present invention, which of the patterns indicating the status of the mobile terminal device matches the information indicating the peripheral state of the mobile terminal device detected by the detection unit. Model pattern means for identifying, and the determination means uses the pattern identified by the model pattern means to determine whether the portable terminal device is in the predetermined state.

  According to this configuration, the mobile terminal device makes a determination after identifying the result detected by the detection means as a pattern. It is easier to manage the determination conditions than in the case of making a determination by using the detection result of the detection means as it is.

  The portable terminal device according to another aspect of the present invention further includes a storage unit that stores the pattern identified by the model pattern unit in a time series, and the determination unit stores the pattern in the storage unit in a time series. It is determined whether or not the predetermined state is used by using the series of patterns that have been set.

  According to this configuration, the mobile terminal device determines whether to switch to the monitoring mode using the sequence of patterns stored in time series in the storage unit. Therefore, for example, a situation that changes in time series, such as when the mobile terminal device is placed on a desk and is stationary, can be used for the determination of switching to the monitoring mode.

  In the mobile terminal device according to another aspect of the present invention, the determination unit is configured to perform the predetermined processing when the pattern sequence matches a sequence to be detected when the mobile terminal device is away from the user. It is determined that it is in the state.

  According to this configuration, the mobile terminal device transitions to the monitoring mode when it is estimated that the mobile terminal device has left the user. Therefore, it is possible to shift to the monitoring mode at a timing desirable for the user.

  The mobile terminal device according to another aspect of the present invention is characterized in that the detection means includes either an acceleration sensor or an illuminance sensor.

  According to this configuration, the mobile terminal device transitions to the monitoring mode in accordance with the acceleration given to the mobile terminal device or the change in the ambient light of the mobile terminal device. Therefore, it is possible to determine whether or not to shift to the monitoring mode based on the surrounding situation that is highly likely to change between when the mobile terminal device is carried by the user and when it is away from the user.

  The mobile terminal device according to another aspect of the present invention is characterized in that a condition for determining that the mobile terminal device is in the predetermined state can be changed by the user.

  According to this configuration, the user can set a mode switching condition suitable for the user.

  In the mobile terminal device according to another aspect of the present invention, the determination unit determines whether the detection result by the detection unit satisfies a predetermined release condition when the mobile terminal device is operating in the monitoring mode. The switching unit cancels the monitoring mode of the portable terminal device when the determination unit determines that the cancellation condition is satisfied.

  Hereinafter, a privacy monitoring system and a control program for a mobile terminal device according to the present embodiment will be described with reference to the drawings. In addition, this embodiment is not limited to what is described below, In the range which does not deviate from the meaning, it can change.

(Embodiment)
In this embodiment, a mobile phone is used as the mobile terminal device. FIG. 1 is an external view showing an example of the configuration of the mobile phone according to the present embodiment.

  The cellular phone according to the present embodiment includes a lower unit portion 4, an upper unit portion 3, and a hinge portion 8, and is configured to be foldable. Each part will be described below.

  First, the lower unit part 4 will be described.

The lower unit unit 4 includes a key operation unit 7, a microphone 6, an illuminance sensor 5, an open / close sensor, a speaker 11, and an acceleration sensor built in the mobile phone 1. The user performs an operation according to the purpose of use using the key operation unit 7. In the present embodiment, setting and control related to the monitoring mode transition method and the monitoring mode release method of the mobile phone 1 are also performed using the key operation unit. The microphone 6 outputs an external sound or a call sound as a transmission sound.

  The illuminance sensor window 5 is used for detecting the intensity of ambient ambient light. The detected ambient light intensity is used, for example, for changing the brightness of the display unit 9 of the mobile phone 1. In the present embodiment, in particular, the user controls the brightness detection of the sensor by holding the illuminance sensor window 5 with a finger, thereby changing the operation mode of the mobile phone 1 to the monitoring mode or switching the monitoring mode. It can be released. The illuminance sensor window 5 is preferably provided in the lower unit 4 that is easy to touch the user's hand. However, the position of the illuminance sensor window 5 is not limited to the lower unit 4 as long as it is easy to touch with the user's hand when the user operates the mobile phone 1. In this embodiment, the illuminance sensor window 5 is provided between the key operation unit 7 and the hinge unit 8. The operation in the monitoring mode is the same as the operation when the security lock is set in the prior art. Details of conditions for transitioning to the monitoring mode and canceling the monitoring mode will be described later.

  The open / close sensor is a sensor that detects an open / closed state of whether the mobile phone 1 is open or closed. The speaker 11 converts the audio data and content data in the Web content and the mobile phone into audio and outputs the audio.

  The acceleration sensor detects the magnitude of a shake received from the outside as a user when the user carries the mobile phone 1 or the like. For example, the user detects a movement such as taking out the mobile phone 1 in a bag and placing it on a desk, or an impact when it is placed on a desk as acceleration. That is, the acceleration sensor is used to detect in what state the user moves or stops the mobile phone 1. The mobile phone 1 according to the present embodiment identifies the state of the mobile phone 1 based on the acceleration detected along with the operation when the user performs an operation of releasing the mobile phone 1 from the hand. Then, the mobile phone 1 transitions to the monitoring mode when the identified state satisfies a specific condition.

  To give a more specific example, it is assumed that the user carries the mobile phone 1 in a bag or a pocket of clothes when the mobile phone 1 is not used, such as while moving. In such a case, by detecting the acceleration applied to the mobile phone 1, it can be identified that the mobile phone is moving with the user. Further, when the mobile phone 1 is placed on a desk or the like, the acceleration is not detected because the mobile phone is stationary after the impact generated at the moment when the mobile phone 1 is placed on the desk or the like is detected. Thus, it can be estimated whether the user has left the mobile phone 1 by using the acceleration detection result. When it can be determined that the user has left the mobile phone 1, the mobile phone 1 transitions to the monitoring mode.

  Next, the upper unit portion 3 will be described.

  The upper unit unit 3 includes a display unit 9, a receiver 10, a camera 2, and a rear display unit 12.

  The display unit 9 displays information in the mobile phone 1 and various information received from the outside via a built-in antenna (not shown) by operating the key operation unit for each purpose.

  The receiver 10 outputs audio data received from the outside such as a conversation during a call or web content. The camera 2 performs shooting, person detection, and data storage according to functions of the mobile phone 1 such as still / moving image shooting, videophone, and the like.

  The rear display unit 12 displays information in accordance with an operation from the user in a state where the foldable mobile phone 1 is closed.

  Next, the internal configuration of the mobile phone 1 according to the present embodiment will be described.

  FIG. 2 is a block diagram showing an internal configuration of the mobile phone according to the present embodiment.

  The cellular phone 1 according to the present embodiment includes a control unit 101, a transmission / reception unit 102, an antenna 113, an acceleration sensor 103, a display unit 107 (corresponding to the display unit 9 described above), and a key operation unit 108 (keys described above). An operation unit 7), a model pattern unit 111, a determination unit 110, a switching unit 109, an open / close sensor 105, an illuminance sensor 104 (corresponding to the illuminance sensor window 5 described above), and a vibrator unit 106. ing. Each of these functional block units is configured to be controlled via each control signal line of the control unit 101.

  The control unit 101 performs overall control of various functions of the mobile phone 1, and specifically includes a CPU (Central Processing Unit) and the like. By controlling the acceleration sensor 103, the model pattern unit 111, the determination unit 110, the illuminance sensor 104, the open / close sensor 105, and the switching unit 109, which will be described later, such as the monitoring mode and mode transition described above, the mode transition process is performed. Realized. Unless otherwise specified below, various data detected by the acceleration sensor 103, the illuminance sensor 104, and the open / close sensor 105 are transferred by the control unit 101 to blocks that require the information.

  The transmitting / receiving unit 102 receives the other party's conversation sound from the antenna 113, for example, when making a call, and transmits the user's conversation sound to the other party. When using the Internet, the user browses, downloads (receives) Web content, and uploads (transmits) data in the mobile phone.

  The storage unit 112 temporarily stores a flash memory for recording a program for controlling the mobile phone 1 and various software, and execution codes and data from the CPU and sensor detection data when executing various software. It is composed of a RAM (Random Access Memory) that serves as a work area for storing and reading / writing data information.

  When the user uses the mobile phone 1, the display unit 107 displays information such as registration information, applications and contents in the mobile phone, and Web content downloaded via the transmission / reception unit. In addition, when the mobile phone 1 is opened during the monitoring mode, the mobile phone 1 displays a standby screen character on the display unit 107 to notify the user that the monitoring mode is being set. The user sets a standby screen character in advance by user setting, and determines a character action and a display method during the monitoring mode.

  The key operation unit 108 includes a numeric keypad. The user uses the key operation unit 108 to select, set and execute various functions of software in the mobile phone, and perform operations such as key input according to the purpose of use. When there is an operation such as a key input, the key operation unit 108 sends an operation signal corresponding to the operation to the control unit 101.

  The acceleration sensor 103 detects the acceleration generated with respect to the mobile phone 1. Based on the detected data, the determination unit 110 determines whether or not the mobile phone 1 is placed in a place away from the user. The determination unit 110 performs this determination by comparing a minute operation pattern and a brightness pattern stored in a model pattern unit 111 described later with detection data from the acceleration sensor 103 and the like. Details will be described later.

  The model pattern unit 111 holds a pattern used for determination of the state of the mobile phone 1 by the determination unit 110, and identifies which pattern the current state of the mobile phone 1 corresponds to. Here, the pattern refers to a state at each moment of the mobile phone classified according to acceleration or the like with respect to the mobile phone 1. There are four patterns recorded by the model pattern unit 111 of the present embodiment: minute operation, SHOCK, posture stillness, and brightness. The minute operation is information obtained by patterning a state in which relatively small acceleration is continuously generated. More specifically, patterning mainly occurs when the user puts the mobile phone in a pocket or bag of clothes, when the mobile phone is used, and when the mobile phone is stored or used. ing. SHOCK is information obtained by patterning a large impact that occurs instantaneously, and corresponds to a case where a large acceleration occurs in a short time. More specifically, the impact generated when the user puts the mobile phone away from his hand and places it on a table or floor is patterned. The posture stationary is a pattern of a state where the mobile phone is stationary. More specifically, the stationary pattern is that the cellular phone is kept stationary for a certain period, and the orientation of the cellular phone at that time is also patterned.

  FIG. 5 is a diagram illustrating an example of a pattern identified by the model pattern portion of the mobile phone 1 according to the present embodiment. The model pattern unit 111 identifies whether the current state of the mobile phone 1 corresponds to a minute movement, a shock, or a stationary posture from the relationship between the magnitude of acceleration and the length of time. In the present embodiment, the magnitude of acceleration is classified by providing acceleration threshold values from level 0 to level 4 as in the example of FIG. Further, the length of time classifies the time when acceleration is continuously detected as in the example of FIG. 5 by providing time thresholds from period 0 to period 4. From the relationship between the acceleration and time, the model pattern portion indicates whether the current state of the mobile phone 1 corresponds to the minute movement shown in FIG. 5, SHOCK, or stationary posture (or none). ) Identify. Note that the acceleration threshold and the time threshold may be fixedly set or arbitrarily set by the user.

  In addition, the model pattern unit 111 temporarily stores information on the pattern identified by itself in the storage unit 112. Here, as will be described later, the determination unit 110 confirms how the pattern stored in the storage unit 112 has changed in time series when determining whether or not to switch modes. Therefore, the model pattern unit 111 stores the information of the pattern identified at each time point in a data structure that can be referred to in a time-series manner. For example, it is conceivable to store in the form of an array, a list, or a FIFO queue. Hereinafter, such pattern information stored in time series is referred to as a pattern series. The model pattern portion is not only the identified pattern, but also other information used by the determination unit 110 for determination (for example, in the case of a “micro-motion” pattern, the amplitude amount of vibration reported from the acceleration sensor). Is also temporarily stored in the storage unit 112.

  The model pattern unit 111 also temporarily stores information on the detected value such as illuminance notified from the illuminance sensor 104 in the storage unit 112 as pattern information. The model pattern unit 111 also temporarily stores information input from the open / close sensor 103 and the key operation unit 108 in the storage unit 112 as pattern information. In the present embodiment, the detection values such as illuminance are stored in the storage unit 112 as they are for the sake of simplicity. However, as with the acceleration information, the values are classified according to time and threshold values, and the classification result is a pattern. The information may be temporarily stored.

  The determination unit 110 determines whether or not the mode of the mobile phone 1 should be switched based on a pattern sequence or the like temporarily stored in the storage unit 112. The determination unit 110 stores information about conditions for determining that the mode should be switched to the monitoring mode and conditions for determining that the mode should be canceled. By comparing this condition with information such as the actual pattern sequence temporarily stored in the storage unit 112, the determination unit 110 determines whether the mode should be switched to the monitoring mode and whether the monitoring mode should be canceled. To do. FIG. 6 is a diagram showing conditions held by the determination unit 110. The conditions are: amplitude of minute motion, amplitude time of minute motion, amplitude interval of minute motion, stationary period of mobile phone, posture of mobile phone, brightness amount, brightness time, interval of fluctuation of brightness (brightness interval ). These pieces of information can be obtained by the determination unit 110 analyzing information such as a pattern series stored in the storage unit 112. When one of these conditions is satisfied as a result of analyzing information such as a series of patterns of a certain period stored in the storage unit 112, the determination unit 110 switches the mode corresponding to the satisfied condition (here Then, it is determined that transition to the monitoring mode or cancellation of the monitoring mode should be performed. When the determination is performed without using information such as the vibration amount, the determination unit 110 may use the pattern series itself as a condition for switching modes.

  Here, the meaning of each condition shown in FIG. 6 will be described. Conditions 601 to 604 are conditions for switching the mobile phone 1 to the monitoring mode, and correspond to a state in which the mobile phone 1 is released from the user. The condition 605 and below are conditions for canceling the monitoring mode.

  First, conditions for switching the mobile phone 1 to the monitoring mode will be described.

  A condition 601 indicates a case where a pattern of minute vibration, SHOCK, and posture stationary is detected in time series. This indicates a state in which the mobile phone 1 is moved (microvibration), placed on a desk or the like (SHOCK), and released (stationary).

  A condition 602 indicates a case where a pattern of minute vibration and posture stationary is detected in time series. A condition 603 indicates a case where a SHOCK and a stationary posture pattern are detected in time series. These conditions are conditions for enabling transition to the monitoring mode even when detection of any of the patterns relating to the acceleration among the patterns constituting the condition 601 fails.

  A condition 604 indicates a case where the posture stationary state continues for a predetermined time (several minutes) or more. This condition indicates a case where the mobile phone 1 has not moved for a long time.

  Next, conditions for canceling the monitoring mode of the mobile phone 1 will be described.

  A condition 605 indicates a case where opening / closing detection, a posture of the mobile terminal, key operation, and a brightness pattern are detected in time series. This is because the user opens the mobile phone 1 with the foldable mobile phone 1 closed (open / closed detection), and the direction and inclination of the mobile phone 1 when the user operates the mobile phone 1 (portable) (The attitude of the terminal) is detected and the user has operated the key button of the mobile phone 1 (key operation), or the user has detected (brightness) how to touch the illumination sensor window on the mobile phone 1 with a finger or the like Indicates. In addition, as a specific example of the “posture of the mobile terminal” to be detected, for example, the main display may face the user side.

  Condition 606 indicates a case in which opening / closing detection, the attitude of the mobile terminal, and the brightness pattern are detected in time series. This is a state where the condition 605 does not include key operation pattern detection.

  A condition 607 indicates a case where a pattern of opening / closing detection, key operation, and brightness is detected in time series. This indicates that the condition 605 does not include detection of the attitude of the mobile terminal.

A condition 608 indicates a case where opening / closing detection and a brightness pattern are detected in time series.
This indicates that the condition 605 does not include detection of the attitude of the mobile terminal and key operations.

  A condition 609 indicates a case where a posture of the mobile terminal, a key operation, and a brightness pattern are detected in time series. This is because, in a straight type portable terminal, the direction and inclination of the portable terminal when the user operates (the attitude of the portable terminal), the key operation of the touch panel or key button (key operation), A state in which the illuminance sensor window is detected by a method of holding (brightness) with a finger or the like is shown.

A condition 610 indicates a case where a key operation and a brightness pattern are detected in time series.
This indicates a condition 609 that does not include the attitude of the mobile terminal when the user uses it.

  The conditions used by the determination unit 110 are not limited to this. For example, the user may arbitrarily set. Moreover, as shown in FIG. 6, the condition for canceling the monitoring mode may be used not only as a transition to the monitoring mode but also as a condition for transitioning to another mode.

  The switching unit 109 switches various control states of the mobile phone 1 and switches the operation mode of the mobile phone 1 to the monitoring mode according to the result determined by the determination unit 110. Further, the switching unit 109 releases the monitoring mode according to the result determined by the determination unit 110.

  The open / close sensor 105 detects whether the cellular phone 1 is closed or opened, and transmits the result to the control unit 101.

  The illuminance sensor 104 detects the intensity of ambient light and notifies the model pattern unit 111 of it. The information notified by the illuminance sensor 104 in the present embodiment is information such as the amount of brightness, the brightness time, and the brightness interval (hereinafter referred to as a detected value of illuminance). The illuminance sensor 104 operates when, for example, the open / close sensor 105 detects that the mobile phone 1 has been opened while the mobile phone 1 is in the monitoring mode, and the illuminance sensor 104 outputs the detected illuminance value via the control unit 101. Send to. In addition, since the detection value of the illuminance by the illuminance sensor 104 is used for the determination of the state of the mobile phone 1 by the determination unit 110 and the model pattern unit 111, the user can hold the illuminance sensor by holding a finger or the like over the illuminance sensor window 5. The mode of the mobile phone 1 can be switched by intentionally controlling the detected value 104. For example, when the detected brightness decreases by holding a finger or the like over the illuminance sensor window 5, it is considered that the user is in a state of holding a mobile phone. As a result, the determination unit 110 determines that the monitoring mode should be switched, and the switching unit 109 cancels the monitoring mode. It should be noted that how to hold the illuminance sensor window 5 with a finger or the like as a condition for switching the mode of the mobile phone 1 can be changed by user setting. For example, it is possible to adjust the case of holding up once, holding up twice, holding up several times. Here, the detected illuminance value is used to cancel the monitoring mode of the mobile phone 1, but a change in the detected illuminance value or a series of changes may be used as a condition for transitioning to another mode. Further, in the mobile phone 1 of the present embodiment, when the key operation or the like is performed before the illumination sensor window 5 is held over with a finger or the like during the monitoring mode, the transition to the monitoring mode cannot be made. This is to prevent the monitoring mode from being forcibly canceled such as an erroneous operation of the monitoring mode being canceled by the user or a peeping by a third party. That is, the mode can be canceled only when the user who knows how to hold the finger or the like over the illuminance sensor window 5 holds the finger or the like in the way. This makes user authentication simpler than password entry or the like.

  The vibration unit 106 generates vibration when there is an incoming call to the mobile phone 1. In particular, the vibrator unit 106 according to the present embodiment operates even when the closed mobile phone 1 is opened during the monitoring mode, and informs the user in advance that the monitoring mode is being set. The movable time and vibration of the vibrator unit 106 can be set by the user.

  Next, the operation procedure of the mobile phone according to the present embodiment will be described with reference to the flowcharts of FIGS. 3 is a flowchart of the operation related to the switching of the mobile phone 1 to the monitoring mode, and FIG. 7 is a flowchart of the operation related to the release of the monitoring mode. In the present embodiment, a case of a foldable mobile phone will be described as an example.

  First, the control unit 101 determines whether the cellular phone 1 is closed and there is no key operation by the user or a third party (step S301). Here, the open / close sensor 105 detects whether or not the mobile phone 1 is closed. The presence or absence of key operation is detected by the key operation unit 108. If there is no key operation when the cellular phone 1 is closed (step S301 / Yes), the operation of the cellular phone 1 proceeds to step S302. When the cellular phone 1 is opened and when the cellular phone 1 is closed and there is a key operation, the determination is repeated until the cellular phone 1 is closed and there is a key operation (step S301 / No). This determination is performed to confirm whether the user is actually using the mobile phone 1. That is, when the mobile phone 1 is opened or closed but there is a key operation, the user is likely to be using the mobile phone 1 and there is no need to shift to the monitoring mode. On the other hand, when the cellular phone 1 is closed and there is no key operation, the cellular phone 1 may be held with the cellular phone 1 closed or the cellular phone 1 may be separated from the user's hand. There is a possibility that a third party peep may occur. Note that even when the user has the cellular phone 1 in the closed state, the determination in step S301 is Yes. This is because the user has the cellular phone 1 without any operation in the near future. This is because there is a high possibility that the mobile phone 1 is separated from the hand.

  In step S302, it is identified whether the information detected by the acceleration sensor 103 and the illuminance sensor 104 corresponds to any pattern. If any pattern can be identified (S302 / Yes), the operation of the mobile phone 1 proceeds to step S303. When no pattern can be identified (S302 / No), the operation of step S302 is repeated until some pattern can be identified.

  In step S <b> 303, the model pattern unit 111 stores a pattern that has been successfully identified in the storage unit 112. At this time, as described above, the model pattern unit 111 stores the pattern in a data structure that can be referred to in time series so that the determination unit 110 can easily handle the pattern. Further, information other than the pattern information (in the above example, the amplitude of vibration, etc.) is also stored if necessary.

  In step S <b> 304, the determination unit 110 analyzes a series of patterns stored in the storage unit 112.

  In step S305, the determination unit 110 checks whether the analysis result satisfies a condition for shifting to the monitoring mode. If the condition is not satisfied, the operation of the mobile phone 1 returns to step S301 and repeats the process from the beginning. If the condition is satisfied, the operation of the mobile phone 1 proceeds to step S307.

  In step S306, the switching unit 109 switches the operation mode of the mobile phone 1 to the monitoring mode.

  Next, the operation for canceling the monitoring mode will be described with reference to FIG.

  First, in step S601, the model pattern unit 111 identifies whether the information detected by the acceleration sensor 103 and the illuminance sensor 104 corresponds to any pattern. If any pattern can be identified (S601 / Yes), the operation of the mobile phone 1 proceeds to step S303. When no pattern can be identified (S601 / No), the operation of step S601 is repeated until a certain pattern can be identified, and the monitoring mode is continued. In the monitoring mode, the mobile phone 1 notifies the user that it is in the monitoring mode by moving the vibrator unit 107 at the opening timing. Further, the mobile phone 1 notifies that it is in the monitoring mode by an image or a character on a standby screen displayed on the display unit after the mobile phone 1 is opened. The reason for performing such an operation is that the mobile phone 1 is not easily peeped when it passes over to a third party. A key operation within a predetermined time is a trigger for canceling the monitoring mode. By keeping the contents of the key operation itself secret, the possibility that the monitoring mode is inadvertently canceled can be further reduced.

  In step S <b> 602, the model pattern unit 111 stores a pattern that has been successfully identified in the storage unit 112. At this time, as described above, the model pattern unit 111 stores the pattern in a data structure that can be referred to in time series so that the determination unit 110 can easily handle the pattern. Further, information other than the pattern information (in the above example, the amplitude of vibration, etc.) is also stored if necessary.

  In step S <b> 603, the determination unit 110 analyzes a series of patterns stored in the storage unit 112.

  In step S604, the determination unit 110 confirms whether the analysis result satisfies a condition for canceling the monitoring mode. If the condition is not satisfied, the operation of the mobile phone 1 returns to step S601 and repeats the process from the beginning. If the condition is satisfied, the operation of the mobile phone 1 proceeds to step S604.

  In step S605, the monitoring unit 109 cancels the monitoring mode of the mobile phone 1.

  Above, description of operation | movement of the mobile telephone 1 which concerns on this Embodiment is complete | finished.

  In the above description of the operation, the control unit 101 determines whether the mobile phone 1 is opened or closed when switching to the monitoring mode, and includes a determination unit including opening / closing of the mobile phone 1 when canceling the monitoring mode. 110 was making a decision. However, the present invention is not limited to this. The determination unit 110 determines opening / closing of the mobile phone 1 when switching to the monitoring mode, and the control unit 101 opens / closes the mobile phone 1 when releasing the monitoring mode. Or may be determined. In the above-described embodiment, the mode is switched using information from the acceleration sensor 103, the illuminance sensor 104, the open / close sensor 105, and the key operation unit 108. However, the present invention is not limited to this. Either information may not be used, or information from other sensors may be used.

  In particular, in the present embodiment, the state of the mobile phone 1 is determined using a sensor that detects the surrounding situation where the mobile phone 1 is placed, such as the detection results of the acceleration sensor 103 and the illuminance sensor 104. Thereby, the user can switch the mobile phone 1 to the monitoring mode or cancel the monitoring mode without performing complicated input. In the present embodiment, the mobile phone 1 automatically transitions to the monitoring mode or cancels the monitoring mode according to the surrounding situation where the mobile phone 1 is placed. Therefore, the mobile phone 1 according to the present embodiment is a device that is easy for the user to use as compared with the prior art that requires an explicit operation for setting or canceling the monitoring mode. In particular, the effect of the present embodiment is not limited to the effect of simply reducing the user input. For example, in the case of an apparatus that requires an explicit user operation to switch to the monitoring mode, the following problem may occur. In other words, for example, if the husband uses the security lock function in front of someone who is close to the family, the husband's family may be doing something that the husband cannot say to the family, Or it's easy to make people close to doubts and misunderstandings, such as keeping in touch with people who don't like it and doing something they can't say without their family's knowledge. For this reason, the actual use of the conventional security lock function may interfere with familiar human relationships. On the other hand, in the case of the mobile phone 1 according to the present embodiment, the mobile phone 1 switches to the monitoring mode according to the state in which the mobile phone 1 is placed. can do.

  Further, in the present embodiment, a foldable mobile phone has been described as an example, but the present invention is not limited to this. As long as the device is equipped with various sensors, the present invention can also be applied to a mobile phone having a shape other than folding or a mobile device other than the phone.

  In the above-described embodiment, the configuration and operation of the mobile phone have been described as an example. However, the idea according to the above embodiment may be realized as a method for realizing the operation of the mobile phone, a program for controlling the operation of the mobile phone, or a recording medium thereof.

  The present invention can be applied to all electronic devices. This is particularly effective for an electronic device having a privacy protection function such as a monitoring mode.
