The function execution condition 142 to be read out is stored. The state determination criteria 141 are various criteria for determining the surrounding state of the smartphone 1 or the state of the smartphone 1 itself using a state detection signal described later. Moreover, the function execution condition 142 memorize | stores the function matched with the movement to the X direction Y direction of smart phone 1 itself (mobile terminal itself), and the state of the smart phone 1. FIG.

  The state detection unit 11 detects the state of the smartphone 1 using a sensor (state sensor) that detects the surrounding state of the smartphone 1 or the state of the smartphone 1 itself. Although the state sensor used by the state detection part 11 is not limited, For example, it is preferable to use the proximity sensor 111 which detects the proximity | contact object of the display part 16, the grip sensor 112 which detects the holding | grip of smart phone 1 itself, etc. Furthermore, you may use the pressure sensor which detects the pressure to smart phone 1 itself, the illumination intensity sensor which detects light, etc. Common mobile phones and smartphones 1 are often equipped with the above sensors as standard equipment. Therefore, the state of the smartphone 1 can be detected without separately providing a special device as the state sensor in the smartphone 1 by using the sensor as the state sensor. When the state detection unit 11 detects the state of the smartphone 1 by the state sensor, the state detection unit 11 outputs a state detection signal indicating the detection to the first state determination unit 101 or the second state determination unit 104. In the present embodiment, a case where the proximity sensor 111 is used as the state sensor will be described.

  The acceleration sensor 12 is a sensor that detects the orientation of the smartphone 1 and the acceleration of the smartphone 1 itself. Here, the acceleration of the smartphone 1 itself refers to a speed change per unit time indicated by the movement of the smartphone 1 itself, for example. By detecting the acceleration, it can be determined whether the smartphone 1 itself is moving. Furthermore, the acceleration sensor 12 outputs a signal indicating the orientation of the smartphone 1 to the first state determination unit 101. Further, when the acceleration sensor 12 detects the acceleration of the smartphone 1 itself, the acceleration sensor 12 outputs an acceleration detection signal indicating the detection to the acceleration determination unit 102.

  The gyro sensor 13 (angular velocity sensor) detects the movement of the smartphone 1 itself in the X direction and the Y direction. The gyro sensor 13 detects the rotational movement of the smartphone 1 itself in the X direction or the Y direction, for example, as shown in FIG. FIG. 2 is a diagram illustrating an example of the movement of the smartphone 1 in the X direction and the Y direction. For example, the gyro sensor 13 detects the angular velocity using the rotation movement of the smartphone 1 itself in one direction in the X direction as a movement in the east direction, and detects the rotation movement in the other direction in the X direction as a movement in the west direction. An angular velocity is detected, an angular velocity is detected with a rotational movement in one direction in the Y direction as a movement in the north direction, and an angular velocity is detected with a rotational movement in the other direction in the Y direction as a movement in the south direction. There may be. When the gyro sensor 13 detects the rotational movement of the smartphone 1 itself in the X direction or the Y direction, the gyro sensor 13 outputs an operation direction detection signal indicating the detection to the operation direction determination unit 103. Here, the functions as the acceleration sensor 12 and the gyro sensor 13 are preferably realized by a six-axis sensor. By using the 6-axis sensor in this way, the acceleration sensor 12 and the gyro sensor 13 can be used together in the smartphone 1, which can contribute to the miniaturization of the smartphone 1.

(Outline of configuration of control unit 10)
The first state determination unit 101 performs a first state determination for determining the state of the smartphone 1 based on the state detection signal from the proximity sensor 111 and the state determination reference 141 stored in the storage unit 14.

When the first state determination unit 101 receives a signal indicating that the smartphone 1 is facing downward from the acceleration sensor 12, the first state determination unit 101 transmits a signal indicating an instruction to start power supply to the proximity sensor 111. Output to. Here, the sleep mode A is a state in which the smartphone 1 enters a sleep state and determines whether or not there is an incoming call. Sleep mode A is applied, for example, to a state in which the smartphone 1 is put in a bag or carried around. Sleep mode B is a state in which the smartphone 1 is in a resting state (sleep state) in which the display unit 16 is suspended while the power is on, and the acceleration sensor 12 is monitoring the acceleration of the smartphone 1 itself. Sleep mode B is applied, for example, to a state in which the smartphone 1 is placed on a table or the like.

  The power control unit 107 (power supply control means) is a signal related to power control from the first state determination unit 101, an acceleration determination signal (AY1) and an acceleration determination signal (BY1) from an acceleration determination unit 102, which will be described later, and an operation direction. Based on the motion direction determination signal (BN2) and the motion direction determination signal (BY2) from the determination unit 103, power supply from the power source 17 to the proximity sensor 111 and the gyro sensor 13 is controlled.

  When receiving an incoming call signal from the communication unit 15, the incoming call detection unit 106 outputs an incoming call signal indicating that there is an incoming call to the acceleration determination unit 102 and the function execution control unit 105.

  Based on the acceleration detection signal from the acceleration sensor 12, the first determination signal from the first state determination unit 101, and the incoming signal from the incoming call detection unit 106, the acceleration determination unit 102 detects the acceleration of the smartphone 1 itself within a predetermined time. It is determined whether it is detected, and an acceleration determination signal (AN1), an acceleration determination signal (AY1), and an acceleration determination signal (BY1) are sent to the first state determination unit 101, the motion direction determination unit 103, and the power supply control unit 107.

The acceleration determination signal (BY1) is a signal indicating that the acceleration detection signal is received from the acceleration sensor 12 within a predetermined time in the sleep mode B state, and the acceleration determination signal (BN1) is the sleep mode B. It is a signal indicating that an acceleration detection signal from the acceleration sensor 12 has not been received within a predetermined time in the state. Details are shown in FIG. FIG. 5 is a diagram illustrating types of signals output from the acceleration determination unit and the operation direction determination unit of the smartphone 1.

  Based on the motion direction detection signal from the gyro sensor 13, the acceleration determination signal (AY1) from the acceleration determination unit 102, and the acceleration determination signal (BY1), the motion direction determination unit 103 is the X direction of the smartphone 1 itself within a predetermined time. Alternatively, it is determined whether or not a rotational movement in the Y direction is detected, and the function execution control unit 105, the power supply control unit 107, and the second state determination unit 104 are notified of the operation direction determination signal (AY2) and the operation direction determination signal ( BN2) and an operation direction determination signal (BY2) are output.

  Here, the movement direction determination signal (AY2) indicates that the gyro sensor 13 has received the movement direction detection signal indicating the detection of the rotation movement of the smartphone 1 itself in the Y direction within a predetermined time in the sleep mode A state. The movement direction determination signal (BY2) is a signal indicating that the movement direction detection signal indicating the rotational movement of the smartphone 1 itself in the X direction or the Y direction within a predetermined time is received from the gyro sensor 13 in the sleep mode B state. The movement direction determination signal (BN2) receives a movement direction detection signal indicating a rotation movement of the smartphone 1 itself in the X direction or the Y direction within a predetermined time from the gyro sensor 13 in the sleep mode B state. This is a signal indicating that the operation has not been performed.

  Based on the state detection signal from the proximity sensor 111 and the state determination reference 141 stored in the storage unit 14, the second state determination unit 104 (determination unit) generates an action direction determination signal (BY2) based on a user operation. It is determined whether it is a thing. The second state determination unit 104 outputs a second determination signal indicating the determination result to the acceleration determination unit 102 and the function execution control unit 105.

  The function execution control unit 105 (function execution control means) includes an operation direction determination signal (AY2) from the operation direction determination unit 103, a second determination signal from the second state determination unit 104, an incoming signal from the incoming call detection unit 106, And based on the function execution condition 142 memorize | stored in the memory | storage part 14, the function matched with the movement to the rotation direction of the smart phone 1 itself detected by the gyro sensor 13 is performed.

The function execution control unit 105 displays an image corresponding to the function to be executed on the display unit 16.

(Details of processing (function execution method) of the smartphone 1)
Hereinafter, the processing of the smartphone 1 in the present embodiment will be described in more detail with reference to FIGS. 3 and 4. 3 and 4 are flowcharts showing the flow of processing performed by the smartphone 1.

  The smartphone 1 turns on the automatic detection operation when the main power is turned on (S1), and sets a sleep transition condition (S2). Here, the smartphone 1 starts an operation of transitioning to a predetermined sleep state, Sleep mode A or Sleep mode B. First, the 1st state determination part 101 confirms whether the display part 16 (liquid crystal surface) of the smart phone 1 has faced the downward direction based on the signal which shows the direction of the smart phone 1 from the acceleration sensor 12 (S3). . When the display unit 16 of the smartphone 1 is facing downward (Yes in S3), the first state determination unit 101 outputs a signal indicating an instruction to start power supply to the proximity sensor 111 to the power control unit 107, The proximity sensor 111 is turned on. The proximity sensor 111 is supplied with power for the first time when the first state determination unit 101 detects that the display unit of the smartphone 1 faces downward. Thereby, the power consumption of the proximity sensor 111 can be suppressed. The direction of the display unit 16 can be arbitrarily set, and the direction of the display unit 16 to be confirmed may be the upward direction. The first state determination unit 101 determines whether or not there is an adjacent object on the display unit 16 by using the proximity sensor 111 (S4). In S4, when there is an approaching object on the display unit 16 within a predetermined time, that is, the first state determination unit 101 indicates that there is an approaching object from the proximity sensor 111 to the display unit 16 within the predetermined time. Is received (Yes in S4), the smartphone 1 is transitioned to the sleep mode B (S5). Further, the first state determination unit 101 outputs a first determination signal indicating that the smartphone 1 is in sleep mode B to the acceleration determination unit 102. On the other hand, when the display unit 16 is not facing downward, or when there is no proximity object to the display unit 16 within a predetermined time (No in S3 or No in S4), the smartphone 1 is transitioned to Sleep mode A ( S29: FIG. 4). Furthermore, the first state determination unit 101 outputs a first determination signal indicating that the smartphone 1 is in the sleep mode A state to the acceleration determination unit 102. When the smartphone 1 transitions to a predetermined sleep state, the proximity sensor 111 is turned off.

(Processing in Sleep mode B)
When the smartphone 1 transitions to the sleep mode B, the acceleration determination unit 102 starts monitoring the acceleration of the smartphone 1 itself by the acceleration sensor 12, that is, the acceleration detection operation (S6), and within a predetermined time in S7 (acceleration detection step). It is determined whether or not the acceleration of the smartphone 1 itself is detected. When the acceleration of the smartphone 1 itself is detected within a predetermined time (Yes in S7), the acceleration determination unit 102 outputs an acceleration determination signal (BY1) to the motion direction determination unit 103 and the power supply control unit 107. When receiving the acceleration determination signal (BY1) from the acceleration determination unit 102, the power control unit 107 starts supplying power to the gyro sensor 13, and the gyro sensor 13 is turned on (S8). In addition, when the motion direction determination unit 103 receives the acceleration determination signal (BY1) from the acceleration determination unit 102, the gyro sensor 13 starts monitoring the rotational movement of the smartphone 1 itself in the X direction, and S9 (direction detection step). , Whether or not there is a rotational movement in the X direction of the smartphone 1 itself within a predetermined time is determined. Here, the movement direction determination unit 103 also starts monitoring the rotational movement of the smartphone 1 itself in the Y direction at the same time as S9, and determines whether or not there is a rotational movement of the smartphone 1 itself in the Y direction within a predetermined time (S19). ). The processing after S19 will be described later. The predetermined time is a time set in advance in consideration of the user's feeling of use, and may be set as appropriate and is not limited.

  Here, in S7, when the acceleration of the smartphone 1 itself is not detected within a predetermined time by the acceleration sensor 12 (No in S7), an acceleration determination signal (BN1) is output to the first state determination unit 101, and the process proceeds to S6. The acceleration determination unit 102 continues monitoring the acceleration of the smartphone 1 itself.

  In S9, when the gyro sensor 13 determines that there is a rotational movement of the smartphone 1 itself in the X direction within a predetermined time, the operation direction determination signal (BY2) is transmitted from the operation direction determination unit 103 to the second state determination unit 104. And output to the power supply control unit 107. When the power supply control unit 107 receives the operation direction determination signal (BY2) from the operation direction determination unit 103, the power supply control unit 107 starts supplying power to the proximity sensor 111, and the proximity sensor 111 is turned on (S10).

  Furthermore, when the second state determination unit 104 receives the movement direction determination signal (BY2) from the movement direction determination unit 103, the second state determination unit 104 uses the proximity sensor 111 to determine whether there is an approaching object on the display unit 16 within a predetermined time (S11). ), Based on the state determination criterion 141 stored in the storage unit 14, it is determined whether the motion direction determination signal (BY2) is due to a user operation. If there is no proximity object to the display unit 16 within the predetermined time (Yes in S11), the second state determination unit 104 determines that the motion direction determination signal (BY2) is due to the user's operation, and the second determination signal Is output to the function execution control unit 105, and the process proceeds to S12.

  In S12, when receiving the second determination signal, the function execution control unit 105 determines whether or not there is an unread mail in the smartphone 1. When there is no unread mail in the smartphone 1 (No in S12), the function execution control unit 105 executes a predetermined operation set in advance in the terminal in S13 or modeA arbitrarily determined by the user (function execution) Step), and then normal operation is performed. When there is unread mail in the smartphone 1 (Yes in S12), the function execution control unit 105 activates an operation for browsing unread mail (S14), and then performs normal operation. In this way, even if the gyro sensor 13 detects the rotation movement of the smartphone 1 itself in the same X direction, the rotation movement of the smartphone 1 itself in the X direction is due to the user's operation. Different functions can be executed depending on the state of the smartphone 1 after determination, unread mail, and presence / absence of an incoming call.

  Here, in S9, by monitoring the movement of the smartphone 1 itself in the X direction by the gyro sensor 13, the gyro sensor 13 did not detect the movement of the smartphone 1 itself in the X direction within a predetermined time. In the case (No in S9), the motion direction determination unit 103 outputs a motion direction determination signal (BN2) indicating that no rotation movement in the X direction has been detected to the acceleration determination unit 102 and the power supply control unit 107. When the power supply control unit 107 receives the operation direction determination signal (BN2) from the operation direction determination unit 103, the gyro sensor 13 is turned off (S16). Furthermore, when the acceleration determination unit 102 receives the motion direction determination signal (BN2) from the motion direction determination unit 103, the acceleration determination unit 102 checks whether the number of times the gyro sensor 13 is turned off is less than 5 (S17). When the number of times the gyro sensor 13 is turned off is less than 5 (Yes in S17), the acceleration determination unit 102 continues monitoring the acceleration of the smartphone 1 itself by the acceleration sensor 12. If the number of times the gyro sensor 13 is turned off is 5 or more (No in S17), the smartphone 1 is transitioned to Sleep mode A (S18).

  In S11, when there is an object close to the display unit 16 within a predetermined time (No in S11), the second state determination unit 104 determines that the motion direction determination signal (BY2) is not due to a user operation. Then, the acceleration determination unit 102 outputs a second determination signal indicating the determination result. When the acceleration determination unit 102 receives the second determination signal, the acceleration determination unit 102 outputs a signal for stopping the power supply to the proximity sensor 111 to the power supply control unit 107, and the proximity sensor 111 is turned off (S15). Further, the acceleration determination unit 102 outputs a signal for stopping the power supply to the gyro sensor 13 to the power control unit 107, and the gyro sensor 13 is turned off (S16).

  Next, the operation after the monitoring of the rotational movement of the smartphone 1 itself in the Y direction by the gyro sensor 13 in S19 described above will be described. The operations of S19 to S21 and S25 to S28 shown in FIG. 3 are the same as the operations of S9 to S11 and S15 to S18 except for the direction of movement of the target smartphone 1 itself. In S21, the second state determination unit 104 determines that the rotation movement of the smartphone 1 itself in the Y direction is due to the user's operation, and the second determination signal is transmitted from the second state determination unit 104 to the function execution control unit 105. (Yes in S21), the function execution control unit 105 determines whether there is an incoming call to the smartphone 1 (S22). When there is an incoming call to the smartphone 1 (Yes in S22), the function execution control unit 105 executes an operation to answer the incoming call and starts a call (S23), and then performs a normal operation. When there is no incoming call to the terminal (No in S22), the function execution control unit 105 executes a predetermined operation set in advance in the terminal or a mode B arbitrarily determined by the user (S24), and then normal operation I do. Note that modeA and modeB are not particularly limited. For example, a schedule table, a game application, etc. can be set and activated, and the user can be customized. In the above description, the process of performing “unread mail presence confirmation” in S12 and “incoming call presence confirmation” in S22 is taken as an example. However, the present invention is not limited to this, and can be customized so that the user can perform a desired process. May be.

(Processing in Sleep mode A)
Next, a process after transition to Sleep mode A will be described with reference to FIG. First, in S29, when the smartphone 1 transits to Sleep mode A, the first state determination unit 101 outputs a first determination signal indicating Sleep mode A to the acceleration determination unit 102. When receiving the first determination signal from the first state determination unit 101, the acceleration determination unit 102 determines whether there is an incoming call to the smartphone 1 (S30). When there is no incoming call to the smartphone 1 (No in S30), the acceleration determination unit 102 starts monitoring the acceleration of the smartphone 1 itself by the acceleration sensor 12 (S31), and determines whether the acceleration of the smartphone 1 itself is not detected for 10 seconds. Determine (S32). When the acceleration of the smartphone 1 itself is not detected for 10 seconds (Yes in S32), the acceleration determination unit 102 generates an acceleration determination signal (AN1) indicating that the acceleration of the smartphone 1 itself is not detected for 10 seconds, as the first state determination unit 101. Output to. When the first state determination unit 101 receives the acceleration determination signal (AN1) from the acceleration determination unit 102, the display unit 16 of the smartphone 1 faces downward based on a signal indicating the direction of the smartphone 1 from the acceleration sensor 12. (S33). When the display unit 16 of the smartphone 1 is facing downward (Yes in S33), the first state determination unit 101 outputs a signal indicating an instruction to start power supply to the proximity sensor 111 to the power control unit 107, The proximity sensor 111 is turned on (S34). Further, the first state determination unit 101 determines whether or not there is an proximity object to the display unit 16 within a predetermined time by the proximity sensor 111 (S35). If there is an approaching object to the display unit 16 within the predetermined time in S35 (Yes in S35), the smartphone 1 is transitioned to Sleep mode B and proceeds to S5 shown in FIG. Here, in S32 and S33, when the acceleration of the smartphone 1 itself is sensed for 10 seconds (No in S32) and when the display unit 16 of the smartphone 1 is not facing downward (No in S33), the acceleration determination The unit 102 determines again whether there is an incoming call to the smartphone 1 (S30). In S35, when there is no proximity object to the display unit 16 within a predetermined time (No in S35), the first state determination unit 101 instructs the power supply control unit 107 to stop the power supply to the proximity sensor 111. The proximity sensor 111 is turned off (S36). Furthermore, the acceleration determination unit 102 determines again whether or not there is an incoming call to the smartphone 1 (S30).

  In S30, when there is an incoming call to the smartphone 1 (Yes in S30), the acceleration determination unit 102 outputs an acceleration determination signal (AY1) to the motion direction determination unit 103 and the power supply control unit 107. When the power supply control unit 107 receives the acceleration determination signal (AY1) from the acceleration determination unit 102, the power supply control unit 107 starts supplying power to the gyro sensor 13, and the gyro sensor 13 is turned on. In addition, when receiving the acceleration determination signal (AY1) from the acceleration determination unit 102, the movement direction determination unit 103 starts monitoring the movement of the smartphone 1 itself in the Y direction by the gyro sensor 13 (S37). It is determined whether or not the sensor 13 detects the rotational movement of the smartphone 1 itself in the Y direction within a predetermined time (S38). When the gyro sensor 13 detects the rotation movement of the smartphone 1 itself in the Y direction within a predetermined time (Yes in S38), the operation direction determination unit 103 sends an operation direction determination signal (AY2) to the function execution control unit 105. Output. When the function execution control unit 105 receives the operation direction determination signal (AY2) from the operation direction determination unit 103, the function execution control unit 105 executes an operation for answering an incoming call and starts a call (S39), and then performs a normal operation. Here, in S38, when the gyro sensor 13 does not detect the rotational movement of the smartphone 1 itself in the Y direction within a predetermined time (No in S38), the operation direction determination unit 103 determines that the smartphone 1 is based on the gyro sensor 13. The monitoring of the movement in the Y direction is continued (S37). As described above, in the sleep mode A, even if the smartphone 1 detects the rotation movement of the smartphone 1 itself in the Y direction as in the sleep mode B, another function is executed depending on the sleep state of the smartphone 1. Can be made. In addition, the movement detection of the rotation of the smartphone 1 in the Y direction is not limited to the Y direction, and may be a direction in which the smartphone 1 is rotated when the user starts a normal call.

[Embodiment 2]
Next, a smartphone 2 according to another embodiment of the present invention will be described below. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted. The smartphone 2 according to the present embodiment and the smartphone 1 according to the first embodiment differ from the smartphone 1 according to the first embodiment in that the grip sensor 112 is further used for state detection by the state detection unit 11. By using the grip sensor 112 for the state detection unit 11, it is possible to confirm whether the smartphone 2 is held by the user. Thereby, there exists an effect which can determine more correctly whether a motion direction determination signal (BY2) is based on a user's operation. Specifically, in S11, when the user's grip on the smartphone 2 can be confirmed within a predetermined time, it is determined that the motion direction determination signal (BY2) is due to the user's operation, and the process proceeds to S12.

  In addition, the determination of the presence or absence of the proximity object to the display unit 16 by the proximity sensor 111 in S4 can be replaced with the determination of the grip of the user on the smartphone 2 by the grip sensor 112. In this case, the state detection unit 11 can include only the grip sensor 112. The operations of the smartphone 2 other than those described above are the same as those of the smartphone 1 according to the first embodiment.

[Embodiment 3]
Next, a smartphone 3 according to still another embodiment of the present invention will be described below. The smartphone 3 according to the present embodiment is different from the smartphone 1 according to the first embodiment in that the acceleration sensor 12 detects the acceleration of the smartphone 1 itself and is linked to a pedometer (not shown) inside the smartphone 3. Specifically, in the acceleration determination unit 102, the threshold value of the acceleration detection signal used as the count of the pedometer and the threshold value of the acceleration detection signal used as the detection of the acceleration of the smartphone 3 itself are set differently. May be. More specifically, the acceleration detection signal used in the pedometer has good sensing sensitivity, that is, the threshold is set low, and the acceleration detection signal used as the acceleration detection signal for detecting the acceleration of the smartphone 3 itself is used in the pedometer. Higher than the threshold value. With the above settings, the acceleration of the smartphone 3 itself can be detected even when the acceleration sensor 12 is used by starting up the pedometer.

[Modification]
The method of linking the pedometer and the detection of the acceleration of the smartphone 3 itself is not limited to the method of the third embodiment described above. A modification of the smartphone 3 according to Embodiment 3 will be described below. In this modification, the acceleration of the smartphone 3 itself by the acceleration sensor 12 is detected using a count of a newly installed pedometer (not shown). Specifically, acceleration detection by the acceleration sensor 12 is output to the pedometer, and 1 count of the pedometer is detected as acceleration of the smartphone 3 itself, and an acceleration detection signal is output to the motion direction determination unit 103. Thus, by using the count by the pedometer, the acceleration of the smartphone 3 itself can be detected even in a state where the acceleration sensor 12 is used by starting the pedometer.

[Example of software implementation]
The control blocks of the smartphone 1 (in particular, the first state determination unit 101, the acceleration determination unit 102, the movement direction determination unit 103, the second state determination unit 104, the function control unit 105, the incoming call detection unit 106, and the power supply control unit 107) are integrated. It may be realized by a logic circuit (hardware) formed in a circuit (IC chip) or the like, or may be realized by software using a CPU (Central Processing Unit).

  In the latter case, the smartphone 1 includes a CPU that executes instructions of a program that is software that realizes each function, a ROM (Read Only Memory) or a storage in which the above-described program and various data are recorded so as to be readable by the computer (or CPU). An apparatus (these are referred to as “recording media”), a RAM (Random Access Memory) for expanding the program, and the like are provided. And the objective of this invention is achieved when a computer (or CPU) reads the said program from the said recording medium and runs it. As the recording medium, a “non-temporary tangible medium” such as a tape, a disk, a card, a semiconductor memory, a programmable logic circuit, or the like can be used. Further, the program may be supplied to the computer via any transmission medium (such as a communication network or a broadcast wave) that can transmit the program. The present invention can also be realized in the form of a data signal embedded in a carrier wave in which the program is embodied by electronic transmission.

[Summary]
A mobile terminal (smart phone 1) according to aspect 1 of the present invention includes an acceleration sensor 12 that detects the acceleration of the mobile terminal itself, an angular velocity sensor (gyro sensor 13) that detects an angular velocity of the mobile terminal itself, and the angular velocity sensor (gyro). Function execution control means (function execution control unit 105) that executes a function associated with the movement in the direction detected by the sensor 13), and the angular velocity sensor (gyro sensor 13) is the acceleration sensor 12 When the acceleration of the mobile terminal itself is detected, the detection operation is started.

  According to the above configuration, when the acceleration of the terminal is detected by the acceleration sensor, the mobile terminal starts the detection operation by the angular velocity sensor and is associated with the movement in the direction detected by the angular velocity sensor. Perform the function. That is, the mobile terminal performs a detection operation by the angular velocity sensor using the detection of the acceleration sensor as a trigger, and executes a function associated with the movement in the direction detected by the angular velocity sensor.

  Here, the state in which the acceleration of the terminal is detected by the acceleration sensor corresponds to, for example, the user lifting the terminal placed on a table or the like. Thus, when the user lifts the terminal and moves the terminal in an arbitrary direction, the corresponding direction is detected by the angular velocity sensor, and the function associated with the detected direction is executed. Therefore, the mobile terminal does not depend on how the user holds the mobile terminal. That is, no matter how the user holds the mobile terminal, a desired function can be activated only by a simple operation of the user.

  In addition, since the acceleration sensor and the angular velocity sensor are sensors that are generally installed in mobile terminals, it is not necessary to add new parts and functions, and does not depend on how the user holds the mobile terminal. A desired function can be activated only by operation. Therefore, there is no need to provide a special device for detecting the acceleration of the terminal and detecting the movement of the terminal in the X direction and the Y direction. A portable terminal capable of starting a desired function can be manufactured at low cost.

  The mobile terminal according to aspect 2 of the present invention is the mobile terminal according to aspect 1, in which the acceleration sensor 12 is in the sleep state in which the display unit that displays the image of the mobile terminal is paused while the mobile terminal is powered on. It is desirable to detect the acceleration of the terminal itself.

  According to the above configuration, the acceleration of the mobile terminal itself can be detected even in a sleep state in which the display unit of the mobile terminal is paused while the mobile terminal is powered on, that is, in a sleep state. For this reason, the acceleration of the mobile terminal itself can be detected without releasing the sleep state. Therefore, a desired function can be activated from the sleep state by a simple operation without performing an operation for canceling the sleep state, turning on the power switch or touching the display panel.

  The mobile terminal according to aspect 3 of the present invention includes the power supply control unit (power supply control unit 107) that controls the supply of power to the angular velocity sensor (gyro sensor 13) in the aspect 1 or 2, and includes the power supply control. The means (power control unit 107) desirably supplies power to the angular velocity sensor (gyro sensor 13) when the acceleration sensor 12 detects the acceleration of the mobile terminal itself.

  According to the above configuration, when the acceleration sensor detects the acceleration of the mobile terminal itself, power is supplied to the angular velocity sensor. That is, power is not supplied to the angular velocity sensor until the acceleration sensor detects the acceleration of the mobile terminal itself. Therefore, power consumption in the angular velocity sensor can be minimized, and power consumption in the portable terminal can be suppressed.

  The mobile terminal according to aspect 4 of the present invention further includes a determination unit (second state determination unit 104) that determines whether or not the user is operating the mobile terminal in any one of the above aspects 1 to 3. The function execution control means (function execution control unit 105) includes the angular velocity sensor (gyro sensor 13) when the determination unit (second state determination unit 104) determines that the user is operating the mobile terminal. It is desirable to execute the function associated with the movement in the direction detected by.

  According to the above configuration, it is possible to determine whether the detection by the angular velocity sensor is due to an operation intended by the user by determining whether the detection by the state detection unit satisfies the condition. When the detection by the angular velocity sensor is an operation not intended by the user, the function execution control unit does not execute a desired function. As a result, it is possible to prevent a malfunction in which a desired function is activated by an operation not intended by the user.

  The function execution program according to the aspect 5 of the present invention is such that when the computer detects an acceleration of the mobile terminal itself (S6) and the acceleration detection step detects the acceleration of the mobile terminal itself, A direction detection step (S7) for detecting its own angular velocity and a function execution step for executing a function associated with the movement in the direction detected by the direction detection step are executed.

  According to said function execution program, there exists an effect similar to the aspect 1. FIG.

  The mobile terminal according to each aspect of the present invention may be realized by a computer. In this case, the mobile terminal is realized by the computer by causing the computer to operate as each unit included in the mobile terminal. A control program and a computer-readable recording medium on which the control program is recorded also fall within the scope of the present invention.
