  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing a configuration of a mobile phone according to an embodiment of the present invention. (A), (b), and (c) are a front view, a right side view, and a rear view of the mobile phone, respectively.

  Referring to FIG. 1, the mobile phone according to the present embodiment includes a cabinet 1 that forms the outline of the mobile phone. The cabinet 1 has a vertically long rectangular shape when viewed from the front. A display surface 2 is disposed on the front surface of the cabinet 1 over almost the entire surface. Similar to the cabinet 1, the display surface 2 has a vertically long rectangular shape.

  The display surface 2 is composed of a liquid crystal panel 3. A touch panel 4 is disposed in front of the liquid crystal panel 3. The touch panel 4 detects a position on the display surface 2 pressed by the user, and outputs a signal (position signal) corresponding to the position. A protective panel 5 is disposed in front of the touch panel 4. The protection panel 5 protects the touch panel 4 from being damaged. On the surface of the protective panel 5, vertical grooves 5 a and horizontal grooves 5 b are formed in a lattice shape in the lower region. When characters and symbols indicating functions are displayed in the square area S surrounded by the grooves 5a and 5b, the square area S becomes one operation key (soft key) for performing various operations. When an operation area R2 to be described later is set to an area without the square area S, in the area without the square area S, for example, the boundary between the adjacent functions can be found by surrounding the function characters with a square line. Such operation keys are displayed.

  A bar 6 extending in the horizontal direction is displayed on the display surface 2. The bar 6 divides the display area of the display surface 2 into two upper and lower screen areas. The area above the bar 6 is the content area R1, and the area below the operation area R2. Various contents such as television images, photographs, and texts are displayed in the content area R1. Various operation keys are displayed in the operation area R2. The bar 6 can be moved up and down in the display area by operating the jog dial 7.

  The jog dial 7 is provided at the center of the back surface of the cabinet 1 and rotates in the vertical direction. When the jog dial 7 rotates upward, the bar 6 moves upward, and when the jog dial 7 rotates downward, the bar 6 moves downward. The jog dial 7 also moves in the front-rear direction and functions as a push button.

  An R button 8 and an L button 9 are arranged on the left and right of the jog dial 7, respectively. With these R button 8 and L button 9, an operation for performing a certain process can be performed.

  Inside the cabinet 1, a camera module 10 is disposed on the top thereof. The imaging lens 10 a and the flash unit 10 b of the camera module 10 face the outside from the back of the cabinet 1.

  In this cellular phone, by fixing the bar 6 at a predetermined position, it is possible to switch to images of various function modes (telephone mode, mail mode, TV mode, music mode, Internet mode, camera mode, etc.). it can.

  For this reason, a plurality of fixed positions (for example, L1 to L6) are set on the display surface 2 in the vertical direction. For example, when the user operates the jog dial 7 to move the bar 6 to the fixed position L5 and presses the jog dial 7 for a short time (short press) while the bar 6 is at the fixed position L5, the TV mode image is displayed. Is displayed. Further, when the bar 6 is moved to the fixed position L6 and the jog dial 7 is pressed for a short time, the television mode image is switched to the mail mode image. In these function mode images, the position of the bar 6 at the beginning of switching is the boundary BL between the content area R1 and the operation area R2.

  FIG. 2A shows a screen display example in the television mode. FIG. 5B shows a screen display example in the mail mode. In the television mode, as shown in FIG. 7A, video content is displayed in the content area R1, and a plurality of operation keys for operations related to video display are displayed in the operation area R2. Further, in the mail mode, as shown in FIG. 5B, input characters and the like are displayed in the content area R1, and operation keys for inputting and transmitting / receiving mail are displayed in the operation area R2.

  FIG. 3 is a block diagram showing a circuit configuration of the mobile phone according to the present embodiment. The cellular phone includes a CPU 100, a TV module 200, a microphone 300, a panel speaker 400, a communication processing unit 500, a liquid crystal display 600, a memory 700, a battery 800, and a power supply unit 900 in addition to the components described with reference to FIG.

  The TV module 200 includes a TV tuner and the like, converts radio waves such as terrestrial digital broadcast waves and analog terrestrial broadcast waves received via the antenna 210 into video signals and sends them to the CPU 100.

  The camera module 10 includes an imaging element 10c in addition to the imaging lens 10a and the flash unit 10b. The imaging lens 10a forms an image of a subject on the imaging element 10c. The image sensor 10c is composed of, for example, a CCD, generates an image signal corresponding to the captured image, and sends it to the CPU 100.

  The microphone 300 converts an audio signal into an electric signal and sends it to the CPU 100. Panel speaker 400 reproduces the audio signal from CPU 100 as audio.

  The communication processing unit 500 converts an audio signal, an image signal, a text signal, or the like from the CPU 100 into a radio signal, transmits the radio signal to the base station via the antenna 510, and converts the radio signal received via the antenna 510 into an audio signal or An image signal, a text signal, etc. are converted and sent to the CPU 100.

  The liquid crystal display 600 includes the liquid crystal panel 3 and a backlight device (not shown) serving as a light source for the liquid crystal panel 3, and displays an image on the liquid crystal panel 3 by a drive signal from the CPU 100.

  The memory 700 includes a ROM (Read Only Memory) and a RAM (Random Access Memory). Among these, the ROM stores a control program for operating the CPU 100, table information referred to in the control program, and the like. For example, a table in which the fixed position of the bar 6 is associated with the function mode is stored as table information. Further, the ROM stores a first setting table and a second setting table which will be described later.

  The RAM stores image data captured by the camera module 10, image data captured from the outside via the communication processing unit 500, text data (mail data), and the like in a predetermined file format. In addition, video contents (television programs, movies, etc.) acquired from the outside by the TV module 200 or the communication processing unit 500 are stored in the RAM.

  The battery 800 is used to supply power to the CPU 100 and other parts of the mobile phone other than the CPU 100, and includes a secondary battery. The battery 800 is connected to the power supply unit 900.

  The power supply unit 900 converts the voltage of the battery 800 into a voltage having a magnitude necessary for each component and supplies the voltage to each component. In addition, the power supply unit 900 supplies the battery 800 with power supplied via an input unit (not shown) of an external power supply to charge the battery 800. The power supply unit 900 is provided with a voltage detection unit 910. The voltage detection unit 910 detects the voltage of the battery 800 and sends it to the CPU 100.

  The CPU 100 controls each unit according to a control program and table information stored in the memory 700 (ROM). For example, the CPU 100 outputs control signals to the panel speaker 400, the liquid crystal display 600, and the like based on input signals from the touch panel 4, the jog dial 7, the R button 8, the L button 9, the microphone 300, the image sensor 10c, and the like. Thereby, processing in various function modes is executed. Further, the CPU 100 determines the remaining amount of the battery 800 based on the voltage signal from the voltage detection unit 910. Further, the CPU 100 performs processing for displaying various images on the liquid crystal display 600 in various function modes.

  Of the control processing functions provided to the CPU 100 by the control program, a processing function (display processing function) for the liquid crystal display 600 is particularly referred to as a “display control unit 110”, and is included in the CPU 100 of FIG. It shall be illustrated.

  The display control unit 110 generates an image to be displayed on the liquid crystal display 600 in a memory (not shown) serving as a work area prepared in the CPU 100, and displays an image signal (RGB signal) for displaying the generated image. ) Is output to the liquid crystal display 600. The display control unit 110 also receives image data sent from the image sensor 10c, image data stored in the memory 700, image data (video content) received via the TV module 200 or the communication processing unit 500, and the like. take in. Then, an image signal (RGB signal) is generated from the captured image data, and the generated image signal is output to the liquid crystal display 600. An image (video) corresponding to the image signal is displayed on the liquid crystal panel 3 of the liquid crystal display 600, that is, the display surface 2.

  As described above, when the jog dial 7 is operated, the operation amount is determined in the CPU 100. Based on this, an image signal is sent from the display control unit 110, whereby the bar 6 displayed on the display surface 2 moves by the amount of operation.

  Now, in the mobile phone according to the present embodiment, various operations are mainly performed by touch panel type operation keys arranged in the operation area R2. Since the touch panel 4 also reacts to a weak press, it is easy to accept an operation not intended by the user. For this reason, for example, when an e-mail text is input using a character input key, the user's finger may touch another operation key adjacent to the character input key, and other processing may be performed. is there. In addition, when the mobile phone is put in a pocket or bag, something may touch the operation key and malfunction.

  Therefore, in the present embodiment, by performing a key operation invalidation process that invalidates the operation of the operation key in accordance with the user's operation, malfunction of the device due to an operation not intended by the user is prevented.

  FIG. 4 is a flowchart for explaining the operation of the key operation invalidation process. FIG. 5 is a diagram showing a screen display example when an operation for invalidating key operation is performed in the mail mode.

  The operation will be described with reference to FIGS. As described above, when the jog dial 7 is operated to switch to the predetermined function mode, an image of the switched function mode is displayed on the display surface 2 based on the image signal from the display control unit 110 (S1). ). For example, in the mail mode, the image shown in FIG. 2B is displayed. The bar 6 is located at the boundary BL between the content area R1 and the operation area R2 when the image is initially displayed (see FIG. 2B).

  When the user operates the jog dial 7 to move the bar 6 from the boundary BL to a predetermined position in the operation area R2, the CPU 100 determines that the position of the bar 6 has moved (S2: YES). Then, the CPU 100 detects a new position of the bar 6 and performs setting for invalidating the operation on the operation key located between the bar 6 and the boundary BL (key invalid area) (S3).

  For example, as shown in FIG. 5A, when the bar 6 is located between the transmission key K1 and the character input key K2, the operation keys above the character input key K2, such as the transmission key K1, are invalid. Thus, the character input key K2 becomes valid. Thereby, the user can input a mail document with the character input key K2. For this reason, when a character is input, for example, even if the user tries to press the character input key K2 of “A” and accidentally touches the send key K1 on the character input key, the mail is erroneously transmitted. Absent.

  As shown in FIG. 5B, when the bar 6 moves to the lowermost part of the operation area R2, the entire operation area R2 becomes a key invalid area, and all operation keys become invalid. Here, when the bar 6 is positioned in the middle of the arrangement area of the 16 character input keys K2, only the character input key K2 in the key invalid area is invalid. However, even if part of the character input key K2 is invalidated, it does not make much sense. Therefore, when a part of the character input key K2 becomes a key invalid area, all the character input keys K2 may be invalidated. Alternatively, all the character input keys K2 may be invalidated in response to all the character input keys K2 becoming key invalid areas. That is, when operation keys having the same function are arranged together, it is desirable to invalidate them together.

  Next, the CPU 100 determines whether or not an operation for prohibiting the movement of the bar 6 has been performed (S4). The user can perform such a movement prohibition operation by, for example, pressing the jog dial 7 for a long time (long pressing). When the CPU 100 determines that the movement prohibiting operation for the bar 6 has been performed (S4: YES), the CPU 100 performs a setting for prohibiting the movement of the bar 6 by operating the jog dial 7 (S6). Based on this setting, the display control unit 110 prevents the bar 6 from moving in the display area even when the jog dial 7 is operated. Thereby, for example, when the user puts the mobile phone in a bag or pocket, if the operation of prohibiting the movement of the bar 6 is performed with all the operation keys disabled, the jog dial in the bag or pocket Even if 7 inadvertently moves, the invalid range of the operation keys does not change, and malfunction of the device is prevented.

  Next, if the movement prohibiting operation of the bar 6 is not performed (S4: NO) and the mode switching operation is performed by short-pressing the jog dial 7 as described above (S6: YES), the CPU 100 determines that the bar 6 at this time Settings are made to switch the image to the function mode according to the position (S7). As a result, an image of a new function mode is displayed on the display surface 2 based on the image signal from the display control unit 110.

  As described above, in this embodiment, the invalid area of the operation key is defined by the boundary BK between the content area R1 and the operation area R2 and the bar 6, and only the operation of the operation key in the invalid area is invalidated. . Therefore, the user can invalidate the operation keys unnecessary for the operation at that time and can keep the necessary operation keys valid, so that the necessary operations can be smoothly performed while preventing an erroneous operation due to an unintended operation. Can do.

  Further, according to the present embodiment, since the desired operation key can be invalidated simply by moving the bar 6, the key invalidation operation can be easily performed.

Furthermore, according to the present embodiment, since the movement of the bar 6 can be prohibited by the user's operation, the bar 6 does not move even if the operation of moving the bar 6 by mistake is performed.
Therefore, for example, even if the jog dial 7 is operated undesirably in a pocket or a bag with all the keys disabled, the keys do not return to the enabled state, and malfunctions caused by undesired operations can be smoothly performed. Can be avoided.

  Although the embodiment of the present invention has been described above, the present invention is not limited to this, and the embodiment of the present invention is also appropriately within the scope of the technical idea shown in the claims. Various modifications are possible. For example, it can be changed as follows.

  In other words, as described below, when one operation key is used to execute a plurality of functions, even if the operation key is invalidated, the operation by the operation key is valid for some functions. (Some functions based on the operation are executed). Further, when the operation key is invalidated, the setting of the function associated with the operation key may be changed.

  FIG. 6 is a flowchart for explaining the operation of another key operation invalidation process. FIG. 7 is a diagram showing the configuration of a setting table used for other key operation invalidation processing. Further, FIG. 8 is a diagram showing an example of a screen display when the key operation invalid operation is performed in the telephone mode.

  The operation will be described with reference to FIGS. Similar to the above embodiment, when an image of a predetermined function mode is displayed on the display surface 2 (S11), the CPU 100 determines whether or not the position of the bar 6 has moved (S12). If it is determined that the position of the bar 6 has moved (S12: YES), the CPU 100 detects a new position of the bar 6 and performs an invalid operation on the operation key located between the bar 6 and the boundary BL in the memory 700. This is executed according to the first setting table stored in (S13).

  For example, as shown in FIG. 8A, when the bar 6 is positioned between the call start key K3 and the numeric keypad K4 in the telephone mode, the call start key K3, the call end key K4, etc. The upper operation keys are candidates for invalidation.

  In the first setting table, as shown in FIG. 7A, whether the function assigned to the operation key is validated or invalidated when the operation key is a candidate for invalidation for each function mode. Is set. When only one function is assigned to one operation key, that function becomes invalid. On the other hand, when two or more functions are assigned to one operation key, some functions are set to be valid. For example, in the telephone mode, when the call start key K3 is a candidate for invalidation, the calling function for making a call is invalidated and the incoming call function for receiving a call is valid for the operation of the call start key K3. .

  The CPU 100 also changes the setting of a predetermined function according to the second setting table stored in the memory 700 (S14). In other words, as shown in FIG. 7B, the second setting table defines how to change the setting of a predetermined function in response to an operation key being a candidate for invalidation. Yes. For example, as described above, when the call start key K3 is set as a candidate for invalidation, the any answer function is set to be invalidated. In addition, a setting is made to disable the calling function other than the call start key K3. The any answer function is a function in which a call is started when any operation key is pressed when an incoming call is received from the other party.

  Thus, when the key invalid area is set as shown in FIG. 8A, the user cannot make a call even if the call start key K3 is operated. On the other hand, when a call is made, the call can be received by operating the call start key K3. Thereby, even if the operation of the call start key K3 is invalidated, it is possible to answer the call without performing the invalidation canceling operation when receiving an incoming call.

  Further, even if the any answer function is set in advance, this function is invalidated, so that a call can be received even if an operation key other than the call start key K3 (for example, the numeric keypad K5 where the operation is valid) is operated. become unable. As a result, even when the mobile phone is put in a bag or the like, it is unlikely that a call start operation is inadvertently caused by an impact or the like when an incoming call is received, and it is possible to prevent a call state from being accidentally entered. Furthermore, since the calling function other than the call start key K3 is also disabled, it is impossible to make a call from an operation key (for example, a phone book function) different from the call start key K3.

  In addition, in this state, all operations on the operation keys in the key invalid area such as the call end key K4 are not accepted (functions based on the operation keys are not executed).

  As shown in FIG. 8B, when the bar 6 is moved to the lowermost part of the operation area R2 and the entire operation area R2 is set as the key invalid area, all operations of the numeric keypad K5 are not accepted. .

  Next, in the state where the operation key is invalidated as described above, if the movement prohibiting operation of the bar 6 is performed (S15: YES), the CPU 100 prohibits the movement of the bar 6 as in the above embodiment. Is set (S16). If a mode switching operation is performed (S17: YES), the CPU 100 switches to a new function mode image based on the position of the bar 6 (S18).

  FIG. 9 is a diagram illustrating a screen display example when an operation for invalidating a key operation is performed in the television mode. As shown in FIG. 5A, the TV mode is a normal mode in which the content area R1 is small and the TV image is displayed small in the vertical direction, and the content area R1 is large as shown in FIG. There is a wide mode in which TV images are displayed horizontally in large size.

  In the normal mode image, for example, two types of operation keys having a channel selection function are displayed in the operation region R2. One is a channel feed key K6, which is a feed key for increasing the number and a feed key for decreasing the number. By operating this channel feed key K6, the channels are sent sequentially. The other is a channel number key K7, which is six number keys corresponding to typical channels. By pressing the channel number key K7, the channel of that number can be selected directly.

  In this normal mode image, as shown in FIG. 9A, when the bar 6 is moved below the channel feed key K6, the operation for the channel feed key K6 is invalid. At this time, if the channel selection key K6 is set as an invalidation candidate in the above-described second setting table, the channel 6 is set to the channel 6 when the channel selection function by the channel number key K7 is invalidated. By moving below the feed key K6, the operation of the channel number key K7 is also invalidated. In this way, it is possible to set a state in which channel selection cannot be performed without moving the bar 6 below the channel number key K7. Therefore, as shown in the figure, even if the channel feed key K6 and the channel number key K7 are arranged apart from each other, and another operation key, here the volume key K8, is arranged between these operation keys, Operation of operation keys does not have to be disabled.

  Next, in the wide mode image shown in FIG. 9B, when the volume key K8 enters the key invalid area, the operation of the volume key K8 is invalidated. At this time, if the volume key K8 is set as the invalidation candidate in the second setting table, the voice output function is invalidated, that is, if the voice is set to be turned off, the bar 6 is moved in this way. As a result, the audio output is stopped. In this way, the sound can be easily muted as necessary while maintaining the original volume.

  In the example of FIG. 9A, the operation of the channel number key K7 is disabled when the operation of the channel feed key K6 is disabled. However, when these operation keys are arranged upside down. The operation of the channel feed key K6 may be invalidated when the operation of the channel number key K7 is invalidated. Further, when the operation of the volume key K8 becomes invalid, a predetermined fixed volume may be set.

  In addition, in said embodiment, although the bar 6 is operated with the jog dial 7, it is not restricted to this, You may make it move the bar 6 by operation of the touch panel 4. FIG. In this case, the user can move the bar 6 up and down by touching the position of the bar 6 with a finger and moving the finger up and down in that state. When the bar 6 moves on the operation key, the operation key is pressed with a finger. Therefore, when the bar 6 is moving, it is possible to prevent the operation key from being received by mistake by disabling the operation of the operation key.

  Further, in the above embodiment, the jog dial 7 can be set to prohibit mode switching and bar 6 movement by short-pressing or long-pressing the jog dial 7. Depending on the position, mode switching and bar 6 movement prohibition may be set. Specifically, when the jog dial 7 is pressed when the bar 6 is at the lowermost part of the operation area R2, the movement of the bar 6 is prohibited, and when the bar 6 is in the middle position (fixed position) of the operation area R2, the jog dial When 7 is pressed, the mode may be switched.

  In general, the movement of the bar 6 is often prohibited when the mobile phone is not used. In this case, all the operation keys are often invalidated. Therefore, in many cases, it is considered that the object can be achieved if the movement is prohibited when the bar 6 is at the lowermost part of the operation region R2. On the other hand, since the lowermost part is not a fixed position for switching modes, the mode cannot be switched when the bar 6 is at the lowermost part. Therefore, it is sufficient that the mode can be switched when the bar 6 is in the middle position (fixed position) of the operation region R2.

  As described above, the movement prohibition of the bar 6 is often performed when the bar 6 is at the lowermost part of the operation region R2, and the mode is switched at a position (fixed position) in the middle of the operation region R2. It is necessary when there is. Therefore, as described above, when the jog dial 7 is pressed when the bar 6 is at the lowermost part of the operation area R2, the movement of the bar 6 is prohibited, and the bar 6 is at a position (fixed position) in the middle of the operation area R2. Even if the jog dial 7 is pressed to switch the mode, the user's needs can be met in most cases.

  In this way, it is not necessary to switch the process according to the pressing time of the jog dial 7, so that the process can be simplified. Further, since the user does not need to worry about the pressing time of the jog dial 7 one by one, the operation can be simplified.

  Further, in the mail mode, when a new mail is sent in a state where the operation key for shifting to the received mail list is invalidated, the operation key may be accepted. In this way, new mail can be confirmed quickly.

  Furthermore, in the above-described embodiment, the jog dial 7 is used as the operation unit for the bar 6 movement operation, the bar 6 movement prohibition operation, and the mode switching operation. However, the present invention is not limited to this, and different operation units may be used. For example, the R button 8 may be an operation unit for mode switching operation, and the L button 9 may be an operation unit for movement prohibition operation of the bar 6.

  Further, in the above embodiment, the moving element of the present invention is an image of the bar 6 extending to the full width of the display surface 2, but the present invention is not limited to this, for example, an image of a horizontal arrow, etc. It is good also as an image of.

  In the above embodiment, the control program for executing the key invalidation process (FIG. 6) and the table information (FIG. 7) used for this are preinstalled in the memory 700 (ROM) in the mobile phone. However, these control programs and table information may be downloaded from a website or the like via the communication processing unit 500 and stored in the memory 700, or a memory card or the like holding these control programs and table information. By attaching the storage medium to the mobile phone, the control program and the table information may be taken into the mobile phone.
