  A plurality of embodiments for carrying out an electronic device, a control method, and a control program according to the present invention will be described in detail with reference to the drawings. Below, the smart phone 1 is taken up and demonstrated as an example of the electronic device which concerns on this invention.

<First embodiment>
An example of the configuration of the smartphone 1 according to the first embodiment will be described with reference to FIGS. 1, 2, and 3. FIG. 1 is a block diagram illustrating a configuration of the smartphone 1 according to the first embodiment. 2 and 3 are external views of the smartphone 1. The smartphone 1 includes a touch panel 2A, a display 2B, a housing 2C, a button 3, a battery 4, an illuminance sensor 5A, a proximity sensor 5B, an acceleration sensor 5C, a gyro sensor 5D, an orientation sensor 5E, and an atmospheric pressure. A sensor 5F, a communication unit 6, a receiver 7A, a microphone 7B, a speaker 7C, an in camera 8A, an out camera 8B, a storage 9, a processor 10, a connector 11, and an earphone jack 12 are provided. .

  Touch panel 2 </ b> A and display 2 </ b> B may be arranged in an overlapping manner, or may be arranged in another place. Each of the touch panel 2A and the display 2B may be provided on a different surface, or a plurality of each may be provided in the smartphone 1. Further, an in-cell type display having both an input function and a display function may be used.

  The touch panel 2A uses a capacitive method. However, methods such as an electromagnetic induction method, a surface acoustic wave method, a pressure sensitive method, a liquid resistance film method, and an infrared method may be arbitrarily used. Touch panel 2A detects the contact and proximity of an operator such as a finger or a stylus pen. Thereby, the user's operation on the smartphone 1 is identified, and information related to the user's input operation is sent to the processor 10. When the capacitive touch panel 2A is employed, it can be detected that the subject is underwater by measuring the change in capacitance. The location where the finger or water touches the touch panel 2A changes in capacitance. When the electrostatic capacitance becomes uniform over the entire surface of the touch panel 2A in the vicinity of a certain value, it can be determined that the liquid has been submerged. When the capacitance becomes uniform in a part of the area, it can be determined that the area of the touch panel 2A is wet.

  Whether the touch panel 2A has detected water may be determined to have detected water when the capacitance becomes uniform over the entire surface of the touch panel 2A, and the touch panel 2A exceeds a threshold value. It may be determined that water is detected when the capacitance becomes uniform in the area. As described above, the touch panel 2A can be used as a water detection unit that detects water.

  The display 2B can display an image. The user can confirm the state of the terminal based on the display on the display 2B. As the display 2B, for example, a display device such as a liquid crystal display, an organic EL display, an inorganic EL display, or electronic paper is used.

The button 3 is pressed to accept various inputs from the user including turning on or off the power to the smartphone 1, switching to the sleep mode or canceling the sleep mode, and adjusting the volume. The number of buttons 3 may be singular or plural. In this embodiment, the button 3 is a physical key using a task switch or a membrane switch. The button 3 can be used for input to the smartphone 1 by being pressed even under water.

  The button 3 is not necessarily limited to the physical key to be pressed as described above. For example, the proximity of an operator such as a finger or a stylus pen may be detected by a capacitance method. Alternatively, it may be a soft key arranged on a part of the touch panel 2A. In the case of detecting the proximity of the operation element by a capacitance method or in the case of a soft key, it is also possible to detect water. That is, the button 3 equipped with these sensors can also have a function as a water detector.

  The battery 4 supplies power to each unit of the smartphone 1.

  The illuminance sensor 5A measures ambient illuminance and is used to control the brightness of the display 2B. As the illuminance measured by the illuminance sensor 5A increases, the processor 10 sets the display 2B brighter to improve the visibility of the display 2B.

  As the proximity sensor 5B, a capacitance method, an ultrasonic method, a photoelectric method, a magnetic method, a guidance method, or the like is arbitrarily used, and detects the proximity of an object to the proximity sensor 5B. In the case of the electrostatic capacity method, it is possible to detect water by using the change in the electrostatic capacity, and in the ultrasonic method or photoelectric method, the attenuation in water is used. That is, the proximity sensor 5B can also have a function as a water detection unit.

  The illuminance sensor 5A and the proximity sensor 5B are not provided separately, but the proximity sensor 5B may also function as the illuminance sensor 5A, or the illuminance sensor 5A may be used as an alternative to the proximity sensor 5B.

  The acceleration sensor 5 </ b> C measures the direction and magnitude of acceleration acting on the smartphone 1.

  The gyro sensor 5 </ b> D measures the angular velocity of the smartphone 1.

  The direction sensor 5E detects the direction of geomagnetism and measures the direction in which the smartphone 1 faces.

  The atmospheric pressure sensor 5F measures the atmospheric pressure acting on the smartphone 1. The atmospheric pressure sensor 5F can also be used as a water detection unit that determines whether the smartphone 1 is in water based on a change in atmospheric pressure. It can also be used as a water depth acquisition unit that estimates water pressure from measured changes in pressure and measures water depth.

  The communication unit 6 includes a circuit for converting a signal for communication and an antenna for transmitting and receiving. The communication standard used by the communication unit 6 is wireless communication. For example, 2G, 3G, LTE (Long Term Evolution), 4G, WiMAX (registered trademark) (Worldwide Interoperability for Microwave Access), Bluetooth (registered trademark), IE 80, IE , NFC (Near Field Communication), IrDA (Infrared Data Association), Zigbee (registered trademark), and the like, and are not limited thereto, and include various wireless communication systems. This functions as a communication unit in the smartphone 1. The communication unit 6 can acquire various types of information including weather information and date / time information by using Internet communication. In the case of having a 3G or LTE communication function, position information can be estimated based on the connected base station. By utilizing this, the communication unit 6 also has a function as a position information acquisition unit.

  The receiver 7A outputs sound. The receiver 7A is mainly used for outputting voice of a call, but can output music, alarms, and the like.

  The speaker 7C also outputs sound. The speaker 7C is mainly used for outputting moving image voice, music, alarm, and the like, and is also used for outputting call voice during hands-free call.

  The smartphone 1 may be provided with only one of the receiver 7A and the speaker 7C, and may also function as the other.

  The microphone 7B receives sound input. The user's voice, surrounding environmental sounds, and the like are converted into sound signals by the microphone 7B. The number of microphones 7B is not limited to one, and a plurality of microphones 7B may be provided.

  The in-camera 8A and the out-camera 8B convert the captured image into an electrical signal. The in-camera 8A is provided on the surface provided with the display 2B of the smartphone 1, and the out-camera 8B is provided on the surface opposite to the surface provided with the in-camera 8A.

  The storage 9 is configured by any one or a combination of storage media such as a flash memory, HDD, SSD, memory card, optical disk, magneto-optical disk, and RAM, and stores programs and data. The storage 9 may include a reading device that reads information from the storage medium in addition to the storage medium.

  The program stored in the storage 9 includes a control program 9A that controls the operation of the smartphone 1 and an application 9B. The control program 9A includes, for example, an OS. When the application 9B receives an input for a corresponding icon, the application 9B is executed in the foreground, and a screen capable of operating the application 9B is displayed on the display 2B. The application 9B may be executed in the background. The application 9B includes various applications such as a shooting camera application preinstalled in the smartphone 1 and an application installed by the user. The storage 9 stores various setting information 9C, sensor information 9D including signal history information from various sensors, results determined from the sensor information 9D, environment information 9E obtained through Internet communication, and the like. .

The processor 10 is an example of a control unit. The smartphone 1 includes at least one processor and provides control and processing capability for realizing various functions described below. According to various embodiments, the processor 10 may implement an IC (Integrated Circuit) or a plurality of communicatively connected ICs and / or discrete circuits. The processor 10 may be implemented by various known techniques. In one embodiment, the processor 10 includes one or more data calculation means or one or more circuits or units that allow data calculation processing. For example, the processor 10 may be one or more processors, controllers, microprocessors, microcontrollers, ASICs (Application Specific Integrated Circuits), digital signal processors, programmable logic devices, FPGAs (Field Programmable Gate Arrays), or these devices, structures, It may be configured by a combination of other devices and structures and perform the functions shown herein.

The processor 10 may include a determination unit and a handoff unit. In some embodiments, the decision unit and handoff unit are implemented as executable instructions stored in memory when executed by processing circuitry included in the processor 10, and each process described herein. Execute. In another embodiment, at least one of the decision unit handoff units may be implemented by a separate IC or discrete circuit communicatively coupled to the processor 10 to perform the respective functions shown herein.

  The control program 9A and the application 9B are executed by the processor 10, and the operation of the smartphone 1 is comprehensively controlled by the processor 10, and various functions are realized.

  The smartphone 1 may include a GPS (Global Positioning System) receiver and a vibrator in addition to the above functional units. Using the signal from the GPS satellite received by the GPS receiver, the processor 10 can detect the current position. Accordingly, not only the communication unit 6 but also the processor 10 has a function as a position information acquisition unit.

  The vibrator has an eccentric motor, a piezoelectric element, or the like, and is used for notifying a user or the like by vibrating the entire smartphone 1.

  Furthermore, the above-described smartphone 1 has sealing members such as packing (not shown) at various places, and has a waterproof function.

  The smartphone 1 according to the present embodiment can be unlocked by using, for example, the acceleration sensor 5C in a situation where the touch panel 2A cannot be used due to being wet with water and input using the touch panel 2A cannot be performed. Thereby, for example, when the user shakes the smartphone 1 underwater, the smartphone 1 detects the operation using the acceleration sensor 5C, and the locked state is released.

  The processing flow of the smartphone 1 according to the first embodiment will be described below with reference to FIG.

  The processor 10 included in the smartphone 1 according to the present embodiment displays, for example, the lock screen 13 as illustrated in FIG. 5 on the display 2B in step S001. The lock screen 13 is a screen that is displayed when the smartphone 1 is in a locked state, and performs user authentication at startup and when the sleep mode is canceled to prevent unauthorized use by others. Alternatively, it may be a screen for preventing malfunction.

  The above-described functions can be disabled according to the settings of the smartphone 1. However, by enabling the function, unauthorized use of the smartphone 1 by another person can be prevented. Or malfunction of smart phone 1 can be prevented.

  When the unlocking operation described later is not performed in the locked state, the locked state is not released, and execution of applications excluding some of the applications installed in the smartphone 1 is restricted.

  When the release operation is performed and the lock state is released, the lock screen 13 is not displayed. Hereinafter, this release operation is expressed as “release the lock screen 13”.

  After step S001, the process proceeds to step S002, and the processor 10 determines whether or not the touch panel 2A detects water. If the touch panel 2A detects water, the process proceeds to step S003, the processor 10 activates the acceleration sensor 5C, and proceeds to step S004.

In step S004, the processor 10 checks the movement of the smartphone 1 with the acceleration sensor 5C, and releases the lock screen 13 when receiving a gesture input such as shaking a predetermined number of times.

  After performing the release operation by the gesture input, various applications can be activated and used by the input means such as the button 3 based on the prior setting. The gesture input may be that the smartphone 1 is shaken a predetermined number of times within a predetermined time, or a combination of movement information such as a direction in which the smartphone 1 is shaken, a movement locus when moving, a movement distance, and a speed. The release operation may be performed. Rather than continuously swinging in a certain direction, swinging with a predetermined trajectory may be used as the release operation. The acceleration sensor 5C is an example, and may be a gesture input using a gyro sensor 5D or other sensors. For example, the rotation of the own device may be measured by the gyro sensor 5D, or the illuminance sensor 5A or the proximity sensor 5B may be covered with a finger or a palm a predetermined number of times within a predetermined time. Various sensors other than the sensors listed above may be used.

  When accepting a release operation based on these gesture inputs, the touch panel 2A may be invalidated. Although it may remain valid, for example, when the smartphone 1 is shaken near the surface of the water, it temporarily enters the water and prevents gestures from being input unintentionally. The touch panel 2A may be invalidated within the time period including several seconds.

  At this time, you may display the screen which displayed the pop-up 14 like FIG. The pop-up 14 may be always displayed while the touch panel 2A detects water, or may be erased after a predetermined time. The message may continue to be displayed at the edge of the screen instead of the pop-up 14 shape.

  In step S004, when a predetermined input based on a prior setting is performed, the process proceeds to step S005, and the processor 10 releases the lock screen 13.

  On the other hand, if water is not detected in step S002, the process proceeds to step S006. In step S006, the processor 10 accepts a release operation by the capacitive touch panel 2A on the screen of FIG. Here, the input of a numeric string is given as an example of a passcode, but the present invention is not limited to the input of a numeric string, and various release means may be used. For example, it may be a canceling operation of moving the finger to draw a predetermined locus while keeping the finger in contact with the touch panel 2A, or a canceling operation such as a password input combining alphanumeric characters instead of a numeric string. . Alternatively, it may be a release operation for moving the finger by a predetermined distance or more while keeping the finger in contact with the touch panel 2A in order to prevent malfunction. The user can set the smartphone 1 and can set an arbitrary number string, character string, locus, etc. as a release operation.

  Next, the processor 10 determines in step S007 whether or not the numeric string input in step S006 is a numeric string registered in advance. In step S007, if the number string does not match that registered in advance, the process returns to step S006.

  As described above, the processor 10 included in the smartphone 1 receives a release operation by the touch panel 2A when the touch panel 2A is not wet with water, and receives input using various sensors such as the acceleration sensor 5C when the touch panel 2A is wet. .

However, the release operation by the gesture input using the acceleration sensor 5C or the gyro sensor 5D can easily mimic the operation for the release operation by another person who has witnessed the gesture input, and the smartphone 1 may be illegally used. There is. Therefore, after the release by the gesture input is performed, if water is no longer detected on the touch panel 2A, a release operation such as input of a numeric string may be obtained immediately thereafter or after a predetermined time has elapsed. This reduces the possibility of unauthorized use by others.

  Alternatively, unlike the case where the lock screen 13 is released by an input to the normal touch panel 2A, the processor 10 may limit the applications that can be executed if the lock screen 13 is released by a release operation using a gesture input. This prevents access to image data, contact information, and other highly confidential information stored in the storage 9 of the smartphone 1.

  It is considered that there is no change in the situation where the input for user authentication is still difficult while the touch panel 2A continues to detect water after the release by the gesture input is performed. Therefore, the transition to the sleep mode over time may be prevented. Alternatively, the lock screen 13 may not be displayed again after the sleep mode is canceled. At this time, in order to continue determining whether or not the user is touching the water, the touch panel 2A may not be turned off even if the display is switched to the sleep mode and the display 2B is turned off. The sleep mode is a state in which the display on the display 2B is erased to save power when a predetermined time has elapsed.

  The case where input using the touch panel 2A cannot be performed has been described so far. However, in the case of an electronic device capable of performing fingerprint authentication, retina authentication, voice authentication, and the like, a case where user authentication underwater cannot be performed is assumed. Therefore, it is possible to accept a release operation using the acceleration sensor 5C, the gyro sensor 5D, the illuminance sensor 5A, or the like.

<Second embodiment>
The smartphone 1 according to the present embodiment cancels the lock screen 13 using various sensors and executes a predetermined application according to the signal of the sensor in a situation where the touch panel 5C cannot be used due to being wet with water. Thereby, for example, the user can cancel the sleep mode of the smartphone 1 and execute a camera application for photographing in water.

  The flow of processing executed by the smartphone 1 according to the second embodiment will be described below using FIG. However, the configuration and processing common to the first embodiment are omitted.

  Steps S101 to S104 in the second embodiment are executed in the same manner as steps S001 to S004 in the first embodiment.

  When the smartphone 1 is shaken a predetermined number of times in step S104, the process proceeds to step S105, and it is determined whether the direction shaken in step S104 is the vertical direction. The vertical direction is the Y direction in FIG. 1, but is not strictly limited to only the Y direction, and the movement trajectory only needs to be included in the predetermined range. For example, the conditions necessary for recognizing that the object has been swung up and down may be such that the direction of shaking is within the range of a radius of 5 cm centering on the Y direction and the moving distance in the Y direction is within a range of 10 cm. Alternatively, it may be centered on the gravitational direction instead of along the Y direction based on the posture of the smartphone. The angle and the direction of shaking are merely examples, and may be changed as appropriate.

At step S104, if the processor 10 recognizes that the signal has been swung in the vertical direction based on the signal from the acceleration sensor 5C, the process proceeds to step S106, and the processor 10 executes a shooting application in the still image shooting mode. When the photographing application is activated, a through image 15 obtained by the out camera 8B is displayed on the display 2B as shown in FIG. In addition, the shutter button 16, the moving image shooting mode switching button 17, and the shot image 18 are displayed as objects superimposed on the through image 15. When the touch operation is performed on the shutter button 16 by the touch panel 2A, the processor 10 performs photographing using the in-camera 8A or the out-camera 8B. When a touch operation is received on the moving image shooting mode switching button 17 by the touch panel 2A, the processor 10 switches the application being shot to the moving image shooting mode. The captured image 18 is displayed by reducing a new one of images captured in the past. When new photographing is performed, the photographed image 18 is overwritten and displayed. When the touch operation is performed on the object of the captured image 18 by the touch panel 2A, the processor 10 changes the display on the display 2B from the state of FIG. 8 to the gallery mode. The gallery mode is a mode for browsing image data stored in the storage 9.

  However, the input by these touch operations cannot be used when the touch panel 2A is wet. Therefore, when the touch panel 2A is wet, all of the shutter button 16, the moving image shooting mode switching button 17 and the captured image 18 may be deleted, or only a part thereof may be deleted. Or you may change to the display which shows that it cannot be used, such as monochrome display.

  If it was not swung up and down at step S104, the process proceeds to step S107, and the processor 10 determines whether it was swung left and right at step S104. The left-right direction is the X direction in FIG. Or it may be a direction perpendicular to the direction of gravity. Similar to step S105, step S107 is not strictly set in the direction, and may be included in a certain range.

  If it is determined in step S107 that the direction swung in step S104 is the left-right direction, the process proceeds to step S108, and the processor 10 executes a shooting application in the moving image shooting mode. However, if it is determined in step S108 that the direction is not the left-right direction, the user's intention is unknown and there is a possibility of erroneous detection, so the process returns to step S101 and the lock screen 13 is displayed again. Alternatively, a message that prompts the user to input a gesture again may be displayed.

  In the above description, as an example, when the smartphone 1 displays the lock screen 13 and is underwater, an example of executing an application for shooting with different settings depending on the direction of shaking is shown. Not limited. For example, a character string may be displayed for communication under water, or another application may be used.

  With the above processing, the user can quickly execute any function after starting or canceling the sleep mode without taking out the smartphone 1 from the water to the water. Therefore, it is possible to shoot quickly without missing a photo opportunity.

  As described above, for example, if only photographing is possible, personal information included in the smartphone 1 is protected even if another person intentionally sinks the smartphone 1 in water and performs a release operation. As shown in FIG. 8, the shooting application installed in the smartphone 1 according to this embodiment displays a reduced display 18 of an image with a new shooting date among images stored in a specific folder in the storage. However, if the use of the smartphone 1 is started by the release operation by the gesture input by the acceleration sensor 5C or the like, the function that leads to such personal information is invalidated. , It does not have to be displayed. Alternatively, the mark 19 may be displayed as shown in FIG. 9 to make it difficult to see, or only the subsequent image may be displayed by performing the release operation by the above-described gesture input.

  Alternatively, while the touch panel 2A is detecting water, the reference destination is accessed to a folder for underwater photographed images different from the above-mentioned specific folder, and among the images or videos stored in the folder, the photographing date / time is new. An image may be displayed. In this case, the captured image while the touch panel 2A is detecting water may be stored in the underwater captured image folder.

  In the above-described example, the smartphone 1 is swung a predetermined number of times, and the operation is changed according to the direction. However, the operation may be changed according to the number of times, or the smartphone 1 estimated from the signal of the acceleration sensor 5C. It may be made different according to the moving distance at the time of shaking.

  For example, when the smartphone 1 is shaken 3 times with a width of 10 cm or more in the vertical direction within 3 seconds, the still image shooting mode is selected. When the smartphone 1 is shaken 5 times with a width of 10 cm or more in the vertical direction, the continuous shooting mode is selected. When it is shaken five times in the left-right direction with a width of about 30 cm, it may be executed in the moving image shooting mode. Alternatively, the input may be a combination of the button 3 and a plurality of sensors, instead of using only one sensor.

  The activation of the shooting mode corresponding to the input pattern is not limited to the above example. Different input patterns may be assigned, or another input means that can be used in water.

  The shooting mode activated corresponding to each input pattern may be a panorama shooting mode, a monochrome shooting mode, or the like.

  As for the above processing, the processing when the lock screen 13 is displayed has been described. However, as a photographing pattern switching means, input by the acceleration sensor 5C or the like is continued after the photographing application is executed and after photographing is performed. You can receive.

  Although the application for shooting has been described so far, a predetermined input pattern may be assigned for ending the application for shooting and for shifting to the sleep mode. As a result, even when the smartphone 1 gets wet with water and the touch panel 2A cannot be used, the user performs a series of operations of taking a picture with the out camera 8B or the in camera 8A from the sleep state and switching to the sleep mode again after the photographing is finished. It can be carried out.

  In the first embodiment, if water is no longer detected on the touch panel 2A after release by gesture input, a release operation such as input of a number string may be requested immediately or after a few seconds. As described above, in the second embodiment, a state in which photographing by the out camera 8B or the in camera 8A is possible may be maintained. As a result, the lock screen 13 is not displayed unintentionally during shooting, and the possibility of missing a photo opportunity is reduced. However, in this case, similarly to the description in the first embodiment, in order to prevent unauthorized use of the smartphone 1, it is desirable to display the lock screen 13 as soon as the photographing application is terminated.

  Up to this point, a smartphone has been described as an example of an electronic device, but the present invention is not necessarily limited to this embodiment. For example, a feature phone, a tablet terminal, a digital camera, an electronic book reader, a game machine, a PDA, a PC, or the like may be used. The same applies to other models equipped with a touch panel.

The specification has been described with reference to specific embodiments in order to provide a thorough and clear disclosure of the technology according to the appended claims. However, the appended claims should not be limited to the above-described embodiments, but all modifications and alternatives that can be created by those skilled in the art within the scope of the basic matters described herein. Should be embodied by a possible configuration.
