<First embodiment>
Referring to FIG. 1, a mobile phone 10 of this embodiment is a kind of mobile terminal, and includes a processor 24 called a CPU or a computer. Further, the wireless communication circuit 14, A / D 16, D / A 20, key input device 26, display driver 28, flash memory 32, RAM 34, and touch panel control circuit 36 are connected to the processor 24. An antenna 12 is connected to the wireless communication circuit 14, a microphone 18 is connected to the A / D 16, and a speaker 22 is connected to the D / A 20 via an amplifier (not shown). A display 30 is connected to the display driver 28. A touch panel 38 is connected to the touch panel control circuit 36.

  The processor 24 is a control IC and controls the entire mobile phone 10. The RAM 34 is used as a work area (including a drawing area) or a buffer area of the processor 24. Content data such as characters, images, sounds, sounds and videos of the mobile phone 10 is recorded in the flash memory 32.

  The A / D 16 converts an analog audio signal for audio or sound input through the microphone 18 connected to the A / D 16 into a digital audio signal. The D / A 20 converts (decodes) the digital audio signal into an analog audio signal and applies the analog audio signal to the speaker 22 via the amplifier. Therefore, sound or sound corresponding to the analog sound signal is output from the speaker 22.

  The key input device 26 includes a call key 26a, a menu key 26b, and an end call key 26c shown in FIG. In addition, information (key data) on keys operated by the user is input to the processor 24. When each key included in the key input device 26 is operated, a click sound is generated. The user can obtain an operational feeling for the key operation by listening to the click sound.

  The display driver 28 controls display on the display 30 connected to the display driver 28 under the instruction of the processor 24. The display driver 28 includes a VRAM that temporarily stores image data to be displayed. Then, the processor 24 stores the image data to be displayed on the display 30 in this VRAM.

  The touch panel 38 is a capacitive system that detects a change in capacitance between electrodes that occurs when a finger (contact member) approaches the surface. For example, one or more fingers touch the touch panel 38. To detect. The touch panel 38 is a pointing device for instructing an arbitrary position within the screen of the display 30. For example, when the touch panel 38 is operated by pressing, stroking, or touching the surface with a finger, the touch panel 38 detects the operation. Then, when the touch panel 38 touches the touch panel 38, the touch panel control circuit 36 that functions as a contact detection unit specifies the position of the finger and outputs coordinate data indicating the operated position to the processor 24. That is, the user can input an operation direction, a figure, or the like to the mobile phone 10 by pressing, stroking, or touching the surface of the touch panel 38 with a finger.

  Here, an operation in which the user touches the surface of the touch panel 38 with a finger is referred to as “touch (contact)”. On the other hand, the operation of releasing the finger from the touch panel 38 is referred to as “release” or “release”. The coordinates indicated by the touch are referred to as “touch point (first position)”, and the coordinates indicated by the release are referred to as “release point (second position)”. The operation of stroking the surface of the touch panel 38 or the operation of moving the finger while touching the touch panel 38 is referred to as “slide”. Further, an operation in which the user touches the surface of the touch panel 38 and subsequently releases it is referred to as “touch and release”. The operations performed on the touch panel 38 such as touch, release, slide, and touch-and-release are collectively referred to as “touch operation (contact operation)”.

  Note that the contact member is not limited to a finger, and may include a conductor or the like. The touch operation may be performed with a touch pen or the like with a conductor attached to the tip. Further, as a detection method of the touch panel 38, a surface-type capacitance method may be employed, or a resistance film method, an ultrasonic method, an infrared method, an electromagnetic induction method, or the like may be used.

  The wireless communication circuit 14 is a circuit for performing wireless communication in the CDMA system. For example, when the user instructs a telephone call using the key input device 26, the wireless communication circuit 14 executes a telephone call process under the instruction of the processor 24 and outputs a telephone call signal through the antenna 12. The telephone call signal is transmitted to the other party's telephone through a base station and a communication network (not shown). Then, when an incoming call process is performed at the other party's telephone, a communicable state is established, and the processor 24 executes a call process.

  The normal call processing will be described in detail. The modulated audio signal transmitted from the other party's telephone is received by the antenna 12. The received modulated audio signal is demodulated and decoded by the wireless communication circuit 14. The received voice signal obtained by these processes is converted to an analog voice signal by the D / A 20 and then output from the speaker 22. On the other hand, the transmission voice signal captured through the microphone 18 is converted into a digital voice signal by the A / D 16 and then given to the processor 24. The transmission signal converted into the digital audio signal is subjected to encoding processing and modulation processing by the wireless communication circuit 14 under the instruction of the processor 24, and is output via the antenna 12. Therefore, the modulated voice signal is transmitted to the other party's telephone through the base station and the communication network.

  When a call signal from the other party's telephone is received by the antenna 12, the wireless communication circuit 14 notifies the processor 24 of an incoming call (sometimes called an incoming call). In response to this, the processor 24 controls the display driver 28 to display the caller information (phone number) described in the incoming call notification on the display 30. At substantially the same time, the processor 24 outputs a ring tone (sometimes called a ringing melody or a ringing voice) from a speaker (not shown). Further, the processor 24 vibrates the mobile phone 10 or emits an LED (not shown) to notify the user of an incoming call.

  When the user performs a response operation using the call key 26a, the wireless communication circuit 14 executes the incoming call process under the instruction of the processor 24, and a communicable state is established. Perform normal call processing.

  In addition, when a call end operation is performed by the call end key 26c after the transition to the call ready state, the processor 24 controls the wireless communication circuit 14 to transmit a call end signal to the call partner. After transmitting the call end signal, the processor 24 ends the call process. The processor 24 also ends the call process when a call end signal is received from the other party first. Furthermore, the processor 24 also ends the call process when a call end signal is received from the mobile communication network regardless of the call partner.

  FIG. 2A is an external view showing the external appearance of the front surface of the mobile phone 10, and FIG. 2B is an external view showing the external appearance of the back surface of the mobile phone 10. Referring to FIG. 2A, the mobile phone 10 has a straight shape and has a flat rectangular casing C. The microphone 18 (not shown) is built in the housing C, and the opening OP2 leading to the built-in microphone 18 is provided on one surface of the housing C in the length direction. Similarly, the speaker 22 (not shown) is built in the housing C, and the opening OP1 leading to the built-in speaker 22 is provided on the other surface in the longitudinal direction of the housing C. The display 30 is attached so that the monitor screen can be seen from the front side of the housing C. The display 30 is provided with a touch panel 38.

  Various keys included in the key input device 26 include a call key 26a, a menu key 26b, and an end call key 26c. These keys are provided on the surface of the casing C.

  For example, the user inputs a telephone number by performing a touch operation on a dial key displayed on the display 30, and performs a telephone call operation using the call key 26a. When the call ends, the user performs a call end operation using the end call key 26c. In addition, the user selects and confirms the menu by performing a touch operation on the soft keys and the menu displayed on the display 30. Then, the user turns on / off the power of the mobile phone 10 by pressing and holding the end call key 26c.

  2A and 2B, the antenna 12, the wireless communication circuit 14, the A / D 16, the D / A 20, the processor 24, the display driver 28, the flash memory 32, the RAM 34, and the touch panel control circuit 36 are the case C. Are not shown in FIGS. 2A and 2B.

  Here, the mobile phone 10 has a lock function that prevents a predetermined function that can be used by the mobile phone 10 such as a telephone call or mail transmission / reception from being executed. For example, when the end call key 26c is operated, the power of the display 30 and the touch panel 38 is turned off and the lock state is set, and the touch operation for executing the telephone function or the like is invalidated. Further, when the power of the display 30 is turned on while the lock state is set, the touch panel 38 is also turned on at the same time, so that a touch operation is detected. And if the touch operation mentioned later is performed, a locked state will be cancelled | released.

  First, referring to FIG. 3A, when the menu key 26b is operated in a state where the lock state is set, the display 30 is turned on and a lock screen is displayed. The display area of the display 30 includes a status display area 60 and a function display area 62. In the status display area 60, an icon (sometimes referred to as a pictograph) indicating the radio wave reception status by the antenna 12, an icon indicating the remaining battery capacity of the secondary battery, and the current date and time are displayed. The current time displayed in the status display area 60 is based on time information output by an RTC (Real Time Clock) (not shown).

  On the other hand, the lock screen displayed in the function display area 62 is composed of a standby image indicating the standby state and a curtain object Co that hides the standby image and prompts the user to slide. Then, when sliding upward from a given position (specific direction), the background image hidden by the curtain object Co is gradually displayed as shown in FIG.

  Further, when determining the slide direction when the finger moves from the first touched (contacted) position, it is determined from the position (touch position) currently touching the touch panel 38 and the touch point. More specifically, it is determined whether or not the vertical coordinate of the current touch position is above the vertical coordinate of the touch point. For example, if the origin of the coordinate system of the touch panel 38 is the lower left in FIG. 3A, the vertical coordinate of the touch point is 30, and the vertical coordinate of the touch position is 70, Since the difference is “+40 (= 70−30)”, the slide direction is determined as the upward direction. On the other hand, if the vertical coordinate of the touch point is 70 and the vertical coordinate of the current touch position is 20, the difference is “−50 (= 20−70)”, so the slide direction is the downward direction. Determined. That is, if the difference between the two vertical axis coordinates is “plus (difference> 0)”, it is determined as upward, and if it is “minus (difference <0)”, it is determined as downward. However, when the difference between the two vertical axis coordinates is “0”, it is determined as the upward direction in the present embodiment. In addition, when the origin of the coordinate system of the touch panel 38 is the upper left, the determination condition for upward and downward is reversed.

  When the slide distance becomes equal to or greater than a predetermined distance (predetermined value), the curtain object Co is not displayed on the display 30 as shown in FIG. 3C, and the locked state is released. However, when the operation for releasing the locked state is interrupted, the curtain object Co is returned to the initial display.

  Thus, since the locked state is not released unless the user slides a predetermined distance or more in a specific direction, it is possible to prevent the locked state from being released due to an erroneous operation. In addition, since the display of the curtain object Co changes according to the slide distance, the user can confirm that the operation for releasing the locked state is correctly input, and the touch operation amount (slide amount) required for releasing the locked state. ) Furthermore, if the operation for releasing the lock state is not correct, the mobile phone 10 can return the display on the display 30 to the final state.

  Note that the background images shown in FIGS. 3A to 3C may be set in advance by the user, or may be images defined by the manufacturer that develops the mobile phone 10.

  In the present embodiment, the touch is disabled by turning off the power of the touch panel control circuit 36 and the touch panel 38. Therefore, the power consumption of the mobile phone 10 is further suppressed. However, in another embodiment, the touch may be invalidated by executing processing of ignoring the input touch coordinates by the processor 24 without turning off the touch panel control circuit 36 and the touch panel 38. .

  FIG. 4 is a diagram showing a memory map 300 of the RAM 34. The memory map 300 of the RAM 34 includes a program storage area 302 and a data storage area 304. A part of the program and data is read from the flash memory 32 all at once or partly and sequentially as necessary, stored in the RAM 34, and then processed by the processor 24.

  The program storage area 302 stores a program for operating the mobile phone 10. For example, a program for operating the mobile phone 10 includes a lock state setting program 310 and a lock state release program 312. The lock state setting program 310 is a program for setting a lock state in the mobile phone 10. The lock state release program 312 is a program for releasing the lock state set in the mobile phone 10.

  Although illustration is omitted, the program for operating the mobile phone 10 includes a program for notifying the incoming call state and a program for establishing the call state.

  In the data storage area 304, a touch buffer 330 and the like are provided, and touch coordinate map data 332, object data 334, and the like are stored. The data storage area 304 is also provided with a lock flag 336, a direction flag 338, a no-operation counter 340, and the like.

  The touch buffer 330 temporarily stores touch points, release points, and coordinates indicating the current touch position output from the touch panel control circuit 36.

  The touch coordinate map data 332 is data for associating the touch coordinates in the touch operation with the display coordinates of the display 30. That is, the processor 24 associates the result of the touch operation performed on the touch panel 38 with the display 30 based on the touch coordinate map data 332. The object data 334 is image data of the curtain object Co displayed on the display 30.

  The lock flag 336 is a flag for determining whether or not the lock state is set. For example, the lock flag 336 is composed of a 1-bit register. When the lock flag 336 is turned on (established), a data value “1” is set in the register. On the other hand, when the lock flag 336 is turned off (not established), a data value “0” is set in the register.

  Further, the direction flag 338 is a flag indicating the determination result of the slide direction. For example, it is turned on when the slide direction is determined to be upward, and is turned off when it is determined to be downward.

  The no-operation counter 340 is a counter for measuring a certain time (for example, 60 seconds), and starts counting when initialized. The no-operation counter 340 is also called an no-operation timer, and when the no-operation timer is executed, the no-operation counter 340 is initialized and starts counting. The no-operation timer is initialized every time a key operation or a touch operation is performed.

  Although illustration is omitted, the data storage area 304 stores a buffer for temporarily storing data output by the RTC, image data for displaying a GUI, and the like, and the operation of the mobile phone 10. Necessary counters and flags are also provided.

  The processor 24 performs a lock state setting process shown in FIG. 5 and a lock state release process shown in FIG. 6 under the control of a Linux (registered trademark) -based OS such as Android (registered trademark) and REX, and other OSs. Including multiple tasks in parallel.

  FIG. 5 is a flowchart of the lock state setting process. For example, when the power of the mobile phone 10 is turned on, the processor 24 determines whether or not an operation is performed in step S1. That is, the processor 24 determines whether or not the no-operation timer has expired because no touch operation or key operation has been performed for a certain period of time. If “YES” in the step S1, for example, if the touch operation and the key operation are not performed for 60 seconds, the processor 24 proceeds to a step S5. On the other hand, if “NO” in the step S1, that is, if the no-operation timer has not expired, the processor 24 determines whether or not an operation for setting the lock state is performed in a step S3. For example, the processor 24 determines whether or not the end call key 26c has been operated. If “NO” in the step S3, that is, if the operation for setting the lock state is not performed, the processor 24 returns to the step S1.

  On the other hand, if “YES” in the step S3, that is, if an operation for setting the lock state is performed, the processor 24 turns off the power of the display 30 in a step S5. That is, the processor 24 issues a command to turn off the power of the display 30 to the power supply circuit. Subsequently, the processor 24 sets a lock state in step S7, and ends the lock state setting process. That is, the processor 24 sets the lock flag 336 to OFF in step S7.

  In another embodiment, the display 30 may be turned off after the lock state is set. In this case, in the lock state setting process of FIG. 5, the order of step S5 and step S7 is switched. That is, in another embodiment, the process of step S5 is executed after the process of step S7 is executed.

  FIG. 6 is a flowchart of the lock state release process. For example, when the menu key 26b is operated while the lock state is set, the processor 24 displays a lock screen in step S21. That is, the processor 24 displays the lock screen shown in FIG. 3A on the display 30 after issuing a command to turn on the power of the display 30. The processor 24 that executes the process of step S21 functions as a display unit.

  Subsequently, the processor 24 determines whether or not it is touched in step S23. That is, it is determined whether or not a touch is detected by the touch panel control circuit 36. If “NO” in the step S23, that is, if a touch is not detected, the processor 24 repeatedly executes the step S23. If “YES” in the step S23, that is, if a touch is detected, the processor 24 stores a touch point in a step S25. That is, the touch point detected by the touch panel control circuit 36 is stored in the touch buffer 330.

  Subsequently, the processor 24 determines whether or not it has been slid in step S27. That is, it is determined whether or not the touch position is a coordinate different from the touch point in a state where the touch is detected by the touch panel control circuit 36. If “NO” in the step S27, that is, if the slide is not performed with respect to the touch panel 38, the processor 24 repeats the process of step S27. If “NO” in the step S27, that is, if the slide is performed with respect to the touch panel 38, the processor 24 determines a sliding direction in a step S29. That is, the processor 24 determines the slide direction based on the vertical coordinate of the touch point and the touch position. Further, on / off of the direction flag 338 is set based on the determination result. The processor 24 that executes the process of step S29 functions as a determination unit.

  Subsequently, the processor 24 determines whether or not the direction is a specific direction in step S31. That is, the processor 24 determines whether the slide direction is the upward direction and determines whether the direction flag 338 is on. If “NO” in the step S31, that is, if the direction flag 338 is turned off (the slide direction is downward), the processor 24 returns to the step S27. If “YES” in the step S31, that is, if the direction flag 338 is turned on (the slide direction is upward), the processor 24 calculates a slide distance in a step S33. That is, the processor 24 calculates the distance (slide distance) by which the contact member has moved from the position where it first contacted from the touch position and the touch point using the three-square theorem. The processor 24 that executes the process of step S33 functions as a calculation unit.

  Subsequently, in step S35, the processor 24 updates the display of the object. That is, the processor 24 changes the display of the curtain object Co shown in FIG. 3A according to the calculated slide distance. The processor 24 that executes the process of step S37 functions as an updating unit.

  Subsequently, in step S37, the processor 24 determines whether or not the slide distance is equal to or greater than a predetermined value. That is, the processor 24 determines whether or not the calculated slide distance is greater than or equal to a distance (predetermined value) sufficient to release the locked state. If “YES” in the step S37, that is, if the slide distance is a distance sufficient to release the locked state, the processor 24 releases the locked state in step S39 and ends the locked state releasing process. That is, the processor 24 sets the lock flag 336 to OFF. The processor 24 that executes the process of step S39 functions as a canceling unit.

  On the other hand, if “NO” in the step S37, that is, if the slide distance is not a sufficient distance to release the lock state, the processor 24 determines whether or not the slide is released in a step S41. That is, the processor 24 determines whether release is detected by the touch panel control circuit 36. If “NO” in the step S41, that is, if no release is detected, the processor 24 returns to the step S33. On the other hand, if “YES” in the step S41, that is, if a release is detected, the processor 24 returns to the step S21.

  In the lock state releasing process shown in FIG. 6, the processes of steps S29-S31 and steps S37, S41 may be omitted. In this case, regardless of the direction and distance of the slide, if the object is slid until it disappears, the locked state is released.

  Further, in the lock state releasing process, only the processes of step S37 and step S41 may be omitted. In this case, the locked state is released if the slide is made in a specific direction regardless of the slide distance.

  In the process of step S33, the slide distance may be calculated from the touch point and the release point. That is, when the slide is performed quickly, the direction and distance of the slide are obtained from the touch point and the release point. On the other hand, when the slide is performed slowly, the direction and distance of the slide are obtained from the touch point and the current touch position. Therefore, the second position described above includes not only the release point but also the current touch position.

  In another embodiment, it may be determined whether or not the release has been made after the process of step S37. When the above determination is made, if “YES”, for example, when the finger is released, the locked state is released in step S39. On the other hand, if “NO”, for example, if the finger is not released, the above determination is repeated until the finger is released. By processing in this way, it is possible to prevent the locked state from being released due to an erroneous operation.

  Thus, in the first embodiment, the user can be urged to slide by the curtain object Co. That is, the mobile phone 10 can prompt the user to slide using the non-language information. Therefore, the mobile phone 10 can release the locked state without depending on the language used by the user.

  In the first example, the touch point in the operation for releasing the locked state does not depend on the display position of the curtain object Co. Therefore, the user may start the slide from an arbitrary position regardless of the display position of the curtain object Co as long as the user can perform the upward slide.

<Second embodiment>
In the second embodiment, the user is urged to slide by the door object Do instead of the curtain object Co. Since the mobile phone 10 of the second embodiment is the same as that of the first embodiment, redundant description such as the electrical configuration and appearance of the mobile phone 10, the memory map of the RAM 34, and the flowchart is omitted.

  7A to 7C, when the menu key 26b is operated while the locked state is set, the door object Do is displayed on the display 30 as shown in FIG. Is displayed. Further, when the door object Do in FIG. 7A is displayed and the slide is made upward, the door of the door object Do starts to open according to the slide distance as shown in FIG. 7B. . Further, when the slide distance is equal to or greater than the predetermined value, the door object Do is in the state shown in FIG. 7C, and the locked state is released. When a certain time (for example, 1 second) elapses, the door object Do disappears, and a standby image is displayed as shown in FIG.

  Here, using the unlocking process shown in FIG. 6, when the process of step S21 is executed, the display on the display 30 is in the state shown in FIG. Further, when the process of step S35 is executed, the display on the display 30 becomes the state shown in FIG. 7B or FIG. Then, when the display on the display 30 is in the state of FIG. 7C, the process of step S39 is executed, so that the locked state is released.

  7A to 7C, there is a double door, but a single door or a sliding door may be used. In addition, the door may be opened after the key is inserted into the keyhole so that the locked state is released more clearly.

<Third embodiment>
In the third embodiment, the user is urged to slide by the flower object Fo instead of the curtain object Co and the door object Do. Since the mobile phone 10 of the third embodiment is the same as that of the first embodiment, redundant description such as the electrical configuration, appearance, memory map of the RAM 34, and flowchart is omitted.

  8A to 8C, when the menu key 26b is operated when the locked state is released, the flower object Fo is displayed on the display 30 as shown in FIG. Is displayed. When the flower object Fo is displayed and the slide is performed in the upward direction, the flower object Fo starts to bloom according to the slide distance as shown in FIG. 8B. Further, when the slide distance is equal to or greater than the predetermined value, the flower object Fo is completely flowered and the locked state is released as shown in FIG. 8C. Then, as in the second embodiment, when a certain time elapses, the flower object Fo disappears and a standby image is displayed as shown in FIG.

  Here, the third embodiment will be described using the unlocking process shown in FIG. 6. When the process of step S21 is executed, the display on the display 30 is in the state of FIG. Further, when the process of step S35 is executed, the display on the display 30 becomes the state of FIG. 8B or FIG. 8C. Furthermore, when the display on the display 30 is in the state of FIG. 8C, the process of step S39 is executed, so that the locked state is released.

  In FIGS. 8A to 8C, the flower object Fo is shown by a flower of the rose family, but it goes without saying that it may be shown by another type of flower. Moreover, the flower shown by the flower object Fo may be shown not only by one but by a plurality of flowers. In this case, when an operation for releasing the locked state is performed, all the flowers bloom at the same time.

  Thus, as can be seen from the second and third embodiments, the user can be urged to slide using various types of objects.

  As can be seen from the above description, the mobile phone 10 has the touch panel 38 on which touch operations such as touch, release, and slide are performed, and can set a lock state that disables the touch operation for executing a telephone function or the like. . For example, when the menu key 26c is operated while the locked state is set, a curtain object Co, a door object Do, or a flower object Fo that prompts a slide to release the locked state is displayed on the display 30. Further, when the slide is performed, the processor 24 calculates the distance and direction of the slide from the coordinates of the touch point and the current touch position. Then, when a predetermined distance slide is performed in the upward direction, the locked state is released.

  As described above, the cellular phone 10 can release the lock state regardless of the language used by the user by displaying the object that prompts the operation for releasing the lock state.

  The objects shown in the first to third examples may be arbitrarily selected by the user.

  Further, by giving a visual effect such as blinking to the curtain object Co, the door object Do, and the flower object Fo displayed on the display 30, the operation of releasing the locked state may be more strongly urged.

  In another embodiment, a predetermined distance for releasing the lock state may be displayed together with the object.

  Further, the specific direction is not limited to the upward direction, and may be the downward direction, the left direction, and the right direction.

  In the present embodiment, the lock state may be set by inputting a predetermined operation in addition to the operation on the call end key 26c. For example, in another embodiment, the lock state may be set by pressing a predetermined key of the key input device 26 a predetermined number of times. The same applies to the above-described end call key 26c. However, since the locked state can be set immediately at the user's desired timing without continuing the non-operation state for a predetermined time, the convenience for the user is improved. Will improve.

  The communication system of the mobile phone 10 is a CDMA system, but an LTE (Long Term Evolution) system, a W-CDMA system, a GSM system, a TDMA system, an FDMA system, a PHS system, or the like may be adopted.

  Further, the lock state setting program 310 and the lock state release program 312 may be stored in the HDD of the data distribution server and distributed to the mobile phone 10 via the network. In addition, the storage medium may be sold or distributed in a state where these programs are stored in an optical disk such as a CD, DVD, or BD (Blu-ray Disc), a USB memory, or a memory card. Then, when the lock state setting program 310 and the lock state release program 312 downloaded through the above-described server or storage medium are installed in a mobile phone having the same configuration as that of this embodiment, the same effect as this embodiment is obtained. Is obtained.

  Furthermore, the present embodiment is not limited to the mobile phone 10 but may be applied to smartphones and PDAs (Personal Digital Assistants).

  In addition, the specific numerical values such as the fixed time given in the present specification are merely examples, and can be appropriately changed according to needs such as product specifications.
