<First embodiment>
Referring to FIG. 1, a mobile phone 10 is a kind of mobile terminal, and includes a processor 24 called a computer or a CPU. The processor 24 includes a wireless communication circuit 14, an A / D converter 16, a D / A converter 20, a key input device 26, a display driver 28, a flash memory 32, a RAM 34, a touch panel control circuit 36, and a camera control circuit 40. Etc. are connected.

  An antenna 12 is connected to the wireless communication circuit 14. A microphone 18 is connected to the A / D converter 16, and a speaker 22 is connected to the D / A converter 20. A display 30 is connected to the display driver 28. A touch panel 38 is connected to the touch panel control circuit 36. An image sensor 42 and a focus lens 44 are connected to the camera control circuit 40.

  The processor 24 manages the overall control of the 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 converter 16 converts an analog audio signal for audio or sound input through the microphone 18 connected to the A / D converter 16 into a digital audio signal. The D / A converter 20 converts (decodes) the digital audio signal into an analog audio signal, and supplies the analog audio signal to the speaker 22 via an amplifier (not shown). Therefore, sound or sound corresponding to the analog sound signal is output from the speaker 22. The processor 24 can adjust the volume of the sound output from the speaker 22 by controlling the amplification factor of the amplifier.

  The key input device 26 is called an operation unit, and includes a call key 26a, a menu key 26b, an end key 26c, and the like. In addition, information (key data) on keys operated by the user is input to the processor 24. Further, when each key included in the key input device 26 is operated, a click sound is generated. Therefore, 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 also includes a video memory (not shown) that temporarily stores image data to be displayed. The display 30 is sometimes called a display unit.

  The touch panel 38 is a capacitance method that detects a change in capacitance between electrodes caused by an object such as a finger approaching the surface. For example, it detects that one or more fingers touch the touch panel 38. To do. The touch panel 38 is provided on the display 30 and is a pointing device for instructing an arbitrary position within the screen. The touch panel control circuit 36 that functions as a detection unit detects a touch operation that is pressed, stroked, or touched within the touch range of the touch panel 38, and outputs coordinate data indicating the position of the touch operation to the processor 24. To do. 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 upper surface of the touch panel 36 with a finger is referred to as “touch”. On the other hand, the operation of releasing the finger from the touch panel 36 is referred to as “release”. The operation of stroking the surface of the touch panel 36 is referred to as “slide”, and the operation of sliding after touching and releasing is referred to as “touch slide”. Further, an operation in which the user touches the touch panel 38 and subsequently releases it is referred to as “touch and release”. The “touch operation” includes operations performed on the touch panel 36 such as touch, release, slide, touch slide, and touch and release.

  Also, the coordinates indicated by the touch are referred to as “touch points” (touch start position), and the coordinates indicated by the release are referred to as “release points” (touch end position).

  Note that the touch operation is not limited to a finger, and may be performed with a touch pen 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 camera control circuit 40 is a circuit for taking a still image or a moving image with the mobile phone 10. For example, when an operation for executing a camera function is performed on the key input device 26, the processor 24 executes the camera function and activates the camera control circuit 40. The camera control circuit 40, the image sensor 42, and the focus lens 44 collectively function as a camera module.

  In the imaging area of the image sensor 42, a light receiving element corresponding to SXGA (1280 × 1024 pixels) is displayed. Therefore, for example, the optical image of the subject is irradiated on the image sensor 42, and in the imaging area, a charge corresponding to the optical image of the subject, that is, a raw SXGA image signal is generated by photoelectric conversion. The user can change the size (number of pixels) of the image data to XGA (1024 × 768 pixels), VGA (640 × 480 pixels), and the like in addition to SXGA.

  When the camera function is executed, the processor 24 activates an image sensor driver built in the camera control circuit 40 in order to display a real-time moving image of the subject, that is, a through image (preview image) on the display 30, and performs an exposure operation and The image sensor driver is instructed to perform a charge readout operation corresponding to the designated readout region.

  The image sensor driver performs exposure of the imaging surface of the image sensor 42 and reading of the charges generated by the exposure. As a result, a raw image signal is output from the image sensor 42. The output raw image signal is input to the camera control circuit 40. The camera control circuit 40 performs processes such as color separation, white balance adjustment, and YUV conversion on the input raw image signal, and outputs the YUV format. Generate image data. Then, the YUV format image data is input to the processor 24.

  The YUV format image data input to the processor 24 is stored (temporarily stored) in the RAM 34 by the processor 24. Further, the stored image data in the YUV format is converted into RGB data by the processor 24 and then given from the RAM 34 to the display driver 28. Then, RGB format image data is output to the display 30. Accordingly, a through image of low pixels (for example, 320 × 240 pixels) representing the subject is displayed on the display 30.

Further, the camera control circuit 40 calculates a focus evaluation value from the raw image signal and outputs the focus evaluation value to the processor 24. The processor 24 executes AF (Autofocus) processing based on the focus evaluation value output from the camera control circuit 40. When the AF process is executed, the camera control circuit 40 adjusts the lens position of the focus lens 44 under the instruction of the processor 24. As a result, a through image in which the subject is in focus is displayed on the display 30.

  Here, when a still image shooting operation is performed on the key input device 26, the processor 24 executes a still image main shooting process. That is, the processor 24 performs signal processing on the raw SXGA image signal output from the image sensor 42, temporarily stores it in the RAM 34, and executes recording processing on the flash memory 32. When the recording process is executed, image data is read from the RAM 34 through the processor 24. Then, the processor 24 associates the meta information with the read image data and records it in the flash memory 32 as one file. Further, the processor 24 outputs a sound for notifying that the main photographing process is being executed from a speaker (not shown).

  The meta information includes time information, image size, and model name (model number) of the mobile phone 10. Further, when a memory card can be connected to the mobile phone 10, the image data may be stored in the memory card. Meta information associated with image data is stored in the Exif format.

  The wireless communication circuit 14 is a circuit for performing wireless communication by the CDMA method. For example, when the user instructs a telephone call (calling) using the key input device 26, the wireless communication circuit 14 executes a telephone call process under the instruction of the processor 24, and sends a telephone call signal via the antenna 12. Is output. 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 into an analog voice signal by the D / A converter 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 converter 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 telephone call signal from the other party's telephone is received by the antenna 12, the radio communication circuit 14 notifies the processor 24 of an incoming call (incoming call). In response to this, the processor 24 controls the display driver 28 to display caller information (such as a telephone 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).

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

Further, when a call end operation is performed with the call end key after shifting to the call ready state, the processor 24 controls the wireless communication circuit 14 to transmit a call end signal to the other party. Then, 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 side surface of the housing C in the vertical 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. A touch panel 38 is provided on the display 30. Further, a camera module (not shown) is also built in the casing C, and an opening OP3 leading to the focus lens 44 and the like of the camera module is provided on the other back surface in the longitudinal direction of the casing C. The key input device 26 includes a call key 26a, a function 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 voice call operation using the call key 26a. When the call ends, the user performs a call end operation using the end call key 26c. Further, the user operates the function key 26b to display a menu screen on the display 30. Further, the user performs menu selection and confirmation by touching the soft keys and menus displayed on the display 30. Further, the user can take an image of the subject by performing a photographing operation with the back surface of the housing C facing the subject.

  Note that since 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 built in the housing C, FIG. ), (B), not shown.

  FIG. 3 is an illustrative view showing an example of a display 30 for displaying a through image. The display 30 includes a status display area 60 including icons indicating date and time, a remaining battery level, a reception status, and the like, and a function display area 62 where a through image is displayed. In the function display area 62, a shooting key 64 for executing shooting processing and an auxiliary function key 66 for executing an auxiliary function of the camera function are displayed as processing keys relating to shooting.

  Referring to FIG. 3, the object scene is arranged in the order of the flower bed and the person from the mobile phone 10 side, and in the function display area 62, a through image focused on the flower bed placed in front of the person is displayed. It is displayed. Here, the user can execute the AF process by touching an arbitrary position in the function display area 62. Further, when the shooting key 64 is operated after the AF process is executed, the image data corresponding to the through image shown in FIG. 3 is stored in the flash memory 32.

  For example, referring to FIG. 4A, when the position of a person included in the through image is touched, the lens position of the focus lens 44 is set so that the focus evaluation value in a predetermined range centered on the touch point is maximized. Adjusted. As a result, as shown in FIG. 4B, a through image focused on the person behind the flower bed is displayed. That is, the user can display a through image that is in focus at that position by simply touching the arbitrary position.

When the auxiliary key 66 shown in FIG. 3 or the like is operated, an auxiliary key group including grid keys 68 and setting keys 70 is displayed in the function display area 62 as shown in FIG. Is displayed instead of. The grid key 68 is a key for displaying in the function display area 62 a grid composed of a plurality of vertical lines and horizontal lines. For example, the user can determine the composition of an image to be captured using the displayed grid.

  The setting key 70 is a key for setting an invalid area in which the touch operation is invalidated in the touch range of the touch panel 38. For example, referring to FIG. 5B, when the setting key 70 is operated, each key displayed in the function display area 62 is erased. In this state, when the position T1 and the position T2 are touched, an invalid area is set in the touch range based on the first coordinates and the second coordinates corresponding to the positions.

  For example, referring to FIG. 5C, the invalid area 74 is set so that the two vertices of the valid area in the touch range are the first coordinate and the second coordinate. In the effective area, a photographing key 64 and a release key 72 are displayed. The release key is also included in the processing key described above.

  Note that the position touched by the user is not limited to that shown in FIG. That is, the user can arbitrarily determine the range of the invalid area 74.

  Here, in the first embodiment, in order to deepen the understanding, the invalid area 74 is illustrated by diagonal lines, but the invalid area 74 is not actually recognized by the user.

  Thus, in this embodiment, since the key is displayed in the valid area, the operability of the mobile phone 10 can be maintained even if the invalid area 74 is set.

  Further, when the cellular phone 10 is held with the invalid area 74 set, even if the user presses the side of the housing C with his / her hand, the touch panel 38 can be erroneously operated with his / her hand or finger. Can be reduced.

  Further, since the ineffective area 74 is not displayed, the through image can be displayed without changing the size thereof, so that the visibility of the through image displayed on the display 30 can be prevented from being deteriorated. Then, the user can grasp the approximate position and range of the invalid area 64 by looking at the photographing key 64 displayed after the invalid area 74 is set.

  When the cancel key 72 is operated, the invalid area 74 is cancelled, and the display on the display 30 returns to the state shown in FIG. That is, the user can arbitrarily set or cancel the invalid area by using the setting key 70 and the cancel key 72.

  In this embodiment, an image can be taken using the touch panel 38 even when an invalid area is set.

  In this embodiment, processing is performed so that the photographing key 64 and the release key 72 are displayed at predetermined positions from the lower right of the effective area.

  Also, in the state shown in FIG. 5B, if a first predetermined time (for example, 30 seconds) elapses without a touch operation being performed, an error message is displayed, and then the state shown in FIG. Return to. That is, even if the setting key 70 is operated and the state is changed to a state where the operation for setting the invalid area is accepted, when the first predetermined time elapses without the touch operation being performed, the display on the display 30 returns to the original state. Returned.

  FIG. 6 is a diagram showing a memory map of the RAM 34. The memory map of the RAM 34 includes a program storage area 302 and a data storage area 304. Further, a part of the program and data are read from the flash memory 32 all at once or partially 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, programs for operating the mobile phone 10 include a camera control program 310, an auxiliary function program 312 and an invalid area setting program 314.

  Although illustration is omitted, the program for operating the mobile phone 10 includes a program for notifying a voice incoming state, and a program corresponding to AF control and photographing control.

  Subsequently, in the data storage area 304, a touch buffer 330 and an invalid area buffer 332 are provided, and touch coordinate map data 334 and GUI data 336 are stored. The data storage area 304 is also provided with a touch flag 338, a setting counter 340, and a touch counter 342.

  The touch buffer 330 temporarily stores touch coordinate data such as a touch point, a release point, and a current touch position obtained by a touch operation. The invalid area buffer 332 temporarily stores the set coordinate range of the invalid area and the data of the first coordinate and the second coordinate.

  The touch coordinate map data 334 is data for converting the touch coordinates stored in the touch buffer 330 into display coordinates on the display 30. The GUI data 336 includes GUI image data displayed on the display 30. Therefore, the processor 24 displays the photographing key 64 and the auxiliary function key 66 shown in FIG. 3 and the like based on the GUI data 336.

  The touch flag 338 is a flag for determining whether or not a touch operation is detected. For example, the touch flag 338 is composed of a 1-bit register. When the touch flag 338 is turned on (established), a data value “1” is set in the register. On the other hand, when the touch flag 338 is turned off (not established), a data value “0” is set in the register. In this embodiment, even if the touch panel control circuit 36 detects a touch operation, if the touch position of the touch operation is included in the invalid area 74, the touch flag 338 is not switched on / off. By doing so, the touch operation is invalidated.

  The setting counter 340 is a counter for measuring the time after the setting key 70 is operated. That is, based on the value of the setting counter 340, the processor 24 determines whether to return the display on the display 30 from the state of FIG. 5B to the state of FIG.

  The touch counter 342 is a counter for measuring a time during which a touch operation is performed. The touch counter 342 will be described in detail in a third embodiment to be described later, and detailed description thereof is omitted here.

  Although not shown, the data storage area 304 stores image data displayed in a standby state, character string data, and the like, and is provided with counters and flags necessary for the operation of the mobile phone 10. It is done.

  The processor 24 operates under the control of the Linux (registered trademark) OS such as Android (registered trademark) and REX, and other OSs, the camera control process shown in FIG. 7, the auxiliary function process shown in FIG. A plurality of tasks including the invalid area setting process shown are processed in parallel.

  FIG. 7 is a flowchart of the camera control process. When an operation for executing the camera function is performed, the processor 24 displays a GUI on the display 30. That is, as shown in FIG. 3, the processor 24 displays the photographing key 66 and the auxiliary function key 66 on the display 30 based on the GUI data 336. Subsequently, in step S3, a through image is displayed. That is, the through image is displayed on the display 30 based on the image data output from the camera control circuit 40. Subsequently, in step S5, it is determined whether or not a camera function end operation has been performed. For example, it is determined whether or not the end call key 26c has been operated. If “YES” in the step S5, for example, when the end key 26c is operated, the camera control process is ended.

  If “NO” in the step S5, that is, if the camera function end operation is not performed, it is determined whether or not the touch is performed in a step S7. That is, it is determined whether or not the touch operation is detected by the touch panel control circuit 36 and the touch flag 338 is turned on. If “NO” in the step S7, that is, if the touch panel 38 is not touched, the process returns to the step S3. If “YES” in the step S7, that is, if the touch panel 38 is touched, it is determined whether or not the position touched in the step S9 is an invalid area. That is, it is determined whether the touch point recorded in the touch buffer 330 and the coordinates indicating the current touch position are included in the coordinate range stored in the invalid area buffer 332. If “YES” in the step S9, for example, if the touch point is included in the coordinate range of the invalid area, the process returns to the step S3.

  If “NO” in the step S9, for example, if the touch point is not included in the coordinate range of the invalid area, it is determined whether or not the AF operation is performed in a step S11. For example, it is determined whether the touched position is within an effective area where no key is displayed. If “YES” in the step S11, for example, as shown in FIG. 4A, if the user touches an arbitrary position, the AF process is executed in a step S13. That is, when the AF process is executed, the lens position of the focus lens 44 is adjusted so that the focus evaluation value becomes maximum within a predetermined range centered on the touch point. And if the process of step S13 is complete | finished, it will return to step S3.

If “NO” in the step S11, for example, if the display range of the key such as the shooting key 64 or the auxiliary function key 66 is touched, it is determined whether or not the shooting operation is performed in a step S15. That is, it is determined whether or not the touch point is included in the display range of the photographing key 64. If “YES” in the step S15, that is, if a touch operation is performed on the photographing key 64, a photographing process is executed in a step S17. That is, as described above, the image data output from the camera control circuit 40 is stored in the flash memory 32. And if the process of step S17 is complete | finished, it will return to step S3. Note that the processor 24 that executes the process of step S17 functions as an execution unit.

  If “NO” in the step S15, that is, if the touch operation is not performed on the photographing key 64, it is determined whether or not an auxiliary key group is displayed in a step S19. That is, as shown in FIG. 5A, it is determined whether or not the grid key 68 and the setting key 70 are displayed instead of the auxiliary function key 66. If “NO” in the step S19, that is, if the auxiliary function key 66 is displayed, it is determined that the key is operated, and the auxiliary key group is displayed in a step S21, and the process returns to the step S3. That is, instead of the auxiliary function key 66, the grid key 68 and the setting key 70 are displayed in the function display area 62.

  If “YES” in the step S19, for example, if the grid key 68 and the setting key 70 are displayed in the function display area 62, the auxiliary function process is executed in a step S23 because these keys are operated. Return to step S3.

  FIG. 8 is a flowchart of auxiliary function processing. As described above, when the process of step S23 is executed, the processor 24 determines whether or not it is the setting key 70. That is, it is determined whether or not the touch point is included in the display range of the setting key 70. If “YES” in the step S41, that is, if the touch operation is performed on the setting key 70, the key display is erased in a step S43. That is, as shown in FIG. 5B, the display of the photographing key 64, the grid key 68, and the setting key 70 is erased. Subsequently, in step S45, an invalid area setting process is executed. The invalid area setting process will be described in detail with reference to the flowchart shown in FIG.

  Subsequently, in step S47, it is determined whether the setting operation is successful. That is, it is determined whether or not the first and second coordinates are stored in the invalid area buffer 332. If “YES” in the step S47, that is, if the first coordinate and the second coordinate are stored in the invalid area buffer 332, an invalid area is set in a step S49. For example, if the first and second coordinates corresponding to the positions T1 and T2 shown in FIG. 5B are stored in the invalid area buffer 332, the invalid area 74 shown in FIG. 5C is set. In step S51, a key is displayed in the effective area. That is, as shown in FIG. 5C, the photographing key 64 and the release key 72 are displayed at predetermined positions from the lower right of the effective area. Then, when the process of step S51 ends, the processor 24 ends the auxiliary function process and returns to the camera control process. The processor 24 that executes the process of step S49 functions as a setting unit, and the processor 24 that executes the process of step S51 functions as a key display unit.

  On the other hand, if “NO” in the step S47, that is, if the setting operation fails, an error display is performed in a step S53, and then the process proceeds to the step S51. For example, when the first predetermined time has passed without the touch operation after the setting key 64 is operated, it is determined that the setting operation has failed in step S47, and “setting of the invalid area has failed” in step S53. A character string is displayed on the display 30. Then, in step S51, the photographing key 64, the grid key 68, and the setting key 70 are displayed so as to be in the state of FIG.

If “NO” in the step S41, that is, if the touch operation is not performed on the setting key 70, it is determined whether or not an invalid area is set in a step S57. That is, it is determined whether or not data indicating the coordinate range of the invalid area is recorded in the invalid area buffer 332. If “NO” in the step S57, that is, if an invalid area is not set, the process proceeds to a step S65. On the other hand, if “YES” in the step S57, as shown in FIG. 5C, for example, if the invalid area 74 is set in the touch range, it is determined whether or not the release key 72 is determined in a step S59. . That is, it is determined whether or not the touch point is included in the display range of the release key 72. If “NO” in the step S59, that is, if the touch operation is not performed on the release key 72, the process proceeds to a step S65.

  If “YES” in the step S59, for example, if a touch operation is performed on the release key 72 shown in FIG. 5C, the invalid area 74 is canceled in a step S61, and valid in a step S63. Redisplay the key in the area. That is, the invalid area buffer 332 is initialized. Further, after the display of the photographing key 64 and the release key 72 is deleted, the photographing key 64, the grid key 68, and the setting key 70 are displayed as shown in FIG. When the process of step S63 ends, the processor 24 returns to the camera control process after finishing the auxiliary function process. The processor 24 that executes the process of step S61 functions as a canceling unit.

  If the invalid area is not set or if the cancel key 72 is not touched even if it is set, it is determined whether or not the grid key 68 is selected in step S65. That is, it is determined whether or not the touch point is included in the display range of the grid key 68. If “YES” in the step S65, that is, if the touch operation is performed on the grid key 68, the grid is displayed in a step S67, and the auxiliary function process is ended. If “NO” in the step S65, that is, if the grid key 68 is not touched, the processor 24 ends the auxiliary function processing.

  FIG. 9 is a flowchart of invalid area setting processing. For example, when step S45 is executed in the auxiliary function process, the processor 24 determines whether or not the first coordinate is designated in step S81. For example, it is determined whether or not the touch panel 38 is touched and the touch point is stored in the touch buffer 330. If “NO” in the step S81, that is, if not touched, the setting counter 340 is incremented in a step S83. That is, the time from when the setting key is touched to when it is touched is measured. Subsequently, in step S85, it is determined whether or not the value of the setting counter is greater than or equal to a first predetermined value. That is, it is determined whether or not a first predetermined time (for example, 30 seconds) has elapsed since the touch operation was performed on the setting key 70 shown in FIG. For example, when the setting counter 340 is counted about every 100 milliseconds, the value of the first predetermined value is “30000”. In step S85, it is determined whether the value of the setting counter 340 is equal to or greater than the first predetermined value. If “YES” in the step S85, that is, if the first predetermined time elapses without being touched, the invalid area setting process is ended and the process returns to the auxiliary function process. On the other hand, if “NO” in the step S85, that is, if the first predetermined time has not passed without being touched, the process returns to the step S81.

  If “YES” in the step S81, for example, if the position T1 shown in FIG. 5B is touched, the first coordinates are stored in a step S87. For example, the coordinates of the position T1 shown in FIG. 5B are stored in the invalid area buffer 332 as the first coordinates. In step S99, the setting counter 340 is initialized. That is, since the first coordinate is stored, the value of the setting counter 340 is initialized. The processor 24 that executes the process of step S87 functions as a first storage unit.

  Subsequently, in step S101, it is determined whether or not the second coordinate is input. That is, it is determined whether or not the touch is made to input the second coordinate. If “NO” in the step S101, that is, if the touch for inputting the second coordinate is not made, the setting counter 340 is incremented in a step S103. In step S105, it is determined whether the setting counter 340 is equal to or greater than a first predetermined value. In addition, since the process of step S103 and step S105 is the same as the process of step S83 and step S85, detailed description is abbreviate | omitted.

  If “YES” in the step S105, that is, if the first predetermined time elapses without touching for inputting the second place after the first coordinate is stored, the invalid area setting process is ended. Return to the auxiliary function processing. On the other hand, if “NO” in the step S105, that is, if the first predetermined time has not elapsed, the process returns to the step S101.

  If “YES” in the step S101, for example, if the position T2 is touched, the second coordinates are stored in a step S107, and the setting counter 340 is initialized in a step S109. For example, in step S107, the coordinates of the position T2 are stored in the invalid area buffer 332 as the second coordinates. The processor 24 that executes the process of step S107 functions as a second storage unit.

<Second embodiment>
In the second embodiment, the invalid area is set and its size is determined based on the touched time. Since the mobile phone 10 of the second embodiment is substantially the same as that of the first embodiment, the description of the electrical configuration of the mobile phone 10, the memory map of the RAM 34, and the overlapping flowcharts will be omitted.

  For example, after the touch operation is performed on the setting key 70 shown in FIG. 5, if the operation time from the touch to release is short, the invalid area 74 is set narrow as shown in FIG. The On the other hand, if the time from the touch to the release is long, the invalid area is set wider as shown in FIG. That is, the user can set the invalid area simply by touching, and can arbitrarily determine its size.

  In the second embodiment, if the operation time is shorter than a second predetermined time (for example, 1 second), the invalid area is not set. This is to prevent the set invalid area from becoming too narrow.

  The processor 24 of the second embodiment performs an invalid area setting process shown in FIG. 11 in addition to a plurality of processes shown in FIGS. 7 and 8 under the control of a Linux-based OS such as Android and REX, and other OSs. Process multiple tasks including in parallel.

  FIG. 11 is a flowchart of invalid area setting processing according to the second embodiment. When step S45 is executed in the auxiliary function process, the processor 24 determines whether or not a touch is made in step S41. That is, it is determined whether or not the touch flag 338 is turned on. In step S133, the touch counter 342 is incremented. That is, the touch counter 342 is incremented to measure the operation time described above. Note that the touch counter 342 is incremented approximately every 50 milliseconds.

  Subsequently, in step S135, it is determined whether or not it has been released. For example, it is determined whether or not the touch flag 338 is switched off when the user lifts his / her finger from the touch panel 38. The processor 24 that executes the processes of steps S133 and S135 functions as a measurement unit.

If “NO” in the step S135, that is, if the touch flag 338 remains on, the process returns to the step S133. If “YES” in the step S135, for example, if the user lifts the finger from the touch panel 38 and the touch flag 338 is switched off, it is determined whether or not the touch counter is equal to or larger than the second predetermined value in a step S137. to decide. That is, it is determined whether or not the operation time is equal to or longer than the second predetermined time. For example, when the touch counter 338 is incremented in the above-described cycle (50 milliseconds), the second predetermined value is “20”. In step S137, it is determined whether the value of the touch counter 338 is equal to or greater than the second predetermined value.

  If “NO” in the step S137, that is, if the operation time is shorter than the second predetermined time, the invalid area setting process is ended without calculating the first coordinate and the second coordinate, and the processor 24 is executed by the upper routine. Return to some auxiliary function processing.

  If “YES” in the step S137, that is, if the operation time is equal to or longer than the second predetermined time, the first coordinate and the second coordinate are calculated based on the value of the touch counter 338 in a step S139.

  More specifically, in the second embodiment, a linear function passing through the origin and the upper right of the function display area 62 is defined in advance with the lower left of the function display area 62 as the origin. Therefore, in step S139, first, the value of the touch counter 338 is converted into the coordinate on the horizontal axis (X axis) of the function display area. Further, the position of the vertical axis (Y axis) is calculated by substituting the converted coordinates into the variable of the horizontal axis (X axis) of the linear function. The position (coordinates) between the horizontal axis and the vertical axis calculated in this way is the first coordinate. Further, in step S139, a coordinate obtained by rotating the first coordinate by 180 degrees with respect to the center point of the function display area 62 is calculated as the second coordinate. Therefore, the processor 24 that executes the process of step S139 functions as a calculation unit. In other embodiments, the first coordinates and the second coordinates may be calculated using other methods.

  Subsequently, in step S141, the calculated first coordinates and second coordinates are stored. That is, the two coordinates described above are stored in the invalid area buffer 332. When the process of step S141 ends, the processor 24 ends the invalid area setting process.

  If “NO” is determined in the step S131, that is, if the touch is not performed after the setting key 70 is touched, the setting counter 340 is incremented in a step S143, and the setting counter 340 is updated in a step S145. It is determined whether or not 1 is a predetermined value or more. That is, also in the second embodiment, the invalid area setting process ends when the first predetermined time elapses without being touched after the setting key 70 is touched.

<Third embodiment>
In the third embodiment, the invalid area is displayed so as to be visible by the user. Further, the size and display range of the invalid area can be arbitrarily changed. Since the mobile phone 10 of the third embodiment is substantially the same as that of the first embodiment, the description of the electrical configuration of the mobile phone 10, the memory map of the RAM 34, and the overlapping flowcharts will be omitted.

  Referring to FIG. 12, in the third embodiment, an invalid area 76 that can be viewed by the user is set. As a result, the user can clearly recognize the position of the invalid area, so that erroneous operations on the touch panel 38 can be further reduced. In addition, the user can arbitrarily change the position and size of the invalid area by the operation described below.

  As shown in FIG. 13A, the ineffective area 76 can be narrowed as shown in FIG. 13B by simultaneously touching two points in the effective area and sliding outward. In addition, although illustration is abbreviate | omitted, when it slides inside, the invalid area | region 76 can be enlarged.

  As shown in FIG. 14A, when the upper right portion of the effective area is touched and slides upward, the display range of the invalid area 74 changes so that the effective area moves upward. That is, the position of the effective area moves according to the direction of the slide. Moreover, although illustration is abbreviate | omitted, not only an upper direction but the user can change the position of an effective area | region arbitrarily by sliding to arbitrary directions.

  As described above, the user can arbitrarily change the size and display range of the invalid area by performing a touch operation for changing the invalid area after setting the invalid area 76.

  In the invalid area 76 of the third embodiment, diagonal lines are drawn so that the through image can be transmitted. However, in other embodiments, the invalid area 76 has a color set to have a high transparency, or transparency. The color which has may be painted.

  In another embodiment, a boundary line is displayed at the boundary between the invalid area and the effective area, or a boundary display shaped like a bracket is displayed at the corner between the invalid area and the effective area. It may be done. The boundary line or boundary display may be a solid line or a broken line, or may be a color line having transparency.

  The processor 24 of the third embodiment is shown in FIG. 15 in addition to a plurality of processes shown in FIGS. 7 and 9 (FIG. 11) under the control of a Linux-based OS such as Android and REX, and other OSs. Multiple tasks including auxiliary function processing are processed in parallel.

  FIG. 15 is a flowchart of auxiliary function processing according to the third embodiment. In the flowchart, the same steps as those in the auxiliary function processing shown in FIG. 8 are given the same step numbers, and detailed description thereof is omitted.

  In step S41, the processor 24 determines whether a touch operation has been performed on the setting key 70. If “YES”, the processor 24 deletes the key display in step S43. Subsequently, in step S45, an invalid area setting process is executed, and in step S47, it is determined whether or not the setting operation is successful. If “YES” in the step S47, an invalid area is set in a step S49.

  Subsequently, in step S161, the set invalid area is displayed. That is, the invalid area 76 is displayed in the function display area 62 as shown in FIG. In step S51, a key is displayed in the effective area, the auxiliary function process is terminated, and the process returns to the camera function process. Further, the processor 24 that executes the process of step S161 functions as an invalid area display unit.

  If “NO” in the step S47, that is, if the setting operation fails, an error is displayed in a step S53, and the process proceeds to the step S51.

  If “NO” in the step S41, that is, if the touch operation is not performed on the setting key 70, it is determined whether or not an invalid area is set in a step S57. If “NO” in the step S57, the process proceeds to a step S65, and if “YES”, it is determined whether or not the release key is operated in a step S59. If “YES” in the step S59, the invalid area is canceled in a step S61, and the key is displayed again in the valid area in a step S63. And if the process of step S63 is complete | finished, an auxiliary function process will be complete | finished.

  If “NO” in the step S59, that is, if the release key is not touched, it is determined whether or not a changing operation is performed in a step S163. For example, it is determined whether or not a change operation for sliding after touching two points at the same time or a change operation for sliding after touching the upper right of the effective area is performed. If “NO” in the step S163, the process proceeds to a step S65.

If “YES” in the step S163, for example, as shown in FIG. 13A, if a changing operation for sliding after touching two points is performed, the invalid area 74 is determined based on the changing operation in a step S165. Recalculate the coordinates of. That is, the coordinate range of the invalid area 76 is recalculated using each release point as the first coordinate and the second coordinate. As shown in FIG. 14A, when a change operation of sliding after touching the upper right of the effective area is performed, the coordinates of the release point are used as the first coordinates, and the second coordinates positioned at the diagonal of the effective area. Is calculated. In other embodiments, the second coordinates may be calculated by a method.

  Subsequently, in step S167, the display of the invalid area 76 is changed. That is, the position where the invalid area 76 is displayed is changed based on the first coordinate and the second coordinate calculated as described above. And if the process of step S167 is complete | finished, an auxiliary function process will also be complete | finished. Further, the processor 24 that executes the process of step S167 functions as a changing unit.

  If “NO” in the step S57 or the step S163, it is determined whether or not the grid key 68 is operated in a step S65. If “YES”, the grid is displayed.

<Fourth embodiment>
In the fourth embodiment, the invalid area can be set without displaying the auxiliary function key 66 and the setting key 70 in the valid area. Since the mobile phone 10 of the fourth embodiment is substantially the same as that of the first embodiment, the description of the electrical configuration of the mobile phone 10, the memory map of the RAM 34, and the overlapping flowcharts will be omitted.

  For example, referring to FIG. 16A, auxiliary function key 66 and setting key 70 are not displayed in function display area 62. Then, if the touch and release is performed twice on the touch panel 38, the invalid area 76 is set as shown in FIG. Here, the touch and release twice in succession is referred to as “double touch” here.

  Next, referring to FIG. 16B, when the invalid area 76 is set by double touch, the photographing key 64 is displayed on the effective amount machine, but the release key 72 is not displayed. In this case, the user can cancel the invalid area 76 by double-touching again within the effective area.

  In the fourth embodiment, the size of the invalid area 76 to be set first is determined in advance. When changing the size or display position, the user performs the changing operation described in the third embodiment. Just do it. In another embodiment, a release key 72 with a cross mark in the effective area may be displayed. In the fourth embodiment, the grid can be displayed by long pressing the menu key 26b.

<Fifth embodiment>
In the fifth embodiment, as shown in FIG. 17, the invalid areas 76 a and 76 b are set separately on the left and right of the function display area 62. Moreover, although illustration is abbreviate | omitted, it may be set up and down and may be set only in any one of each edge | side. Further, since the cellular phone 10 of the fifth embodiment is substantially the same as the first embodiment, the description of the electrical configuration of the cellular phone 10, the memory map of the RAM 34, and the overlapping flowcharts will be omitted.

  Note that the first embodiment to the fifth embodiment can be arbitrarily combined, and a specific combination can be easily imagined, and thus detailed description thereof is omitted.

The invalid area may be set based on a graphic drawn by the user through a touch operation. In this case, for example, the invalid area is set based on a rectangle that can surround the drawn figure with the minimum size. Moreover, although the effective area | region of each Example was shown with the rectangle,
It may be oval or other polygons.

  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, and the like may be employed.

  Further, the plurality of programs used in this embodiment may be stored in the HDD of the data distribution server and distributed to the mobile phone 10 via the network. Further, the storage medium may be sold or distributed in a state where a plurality of programs are stored in a storage medium such as an optical disk such as a CD, DVD, or BD (Blu-ray Disc), a USB memory, or a memory card. When a plurality of programs 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 that of this embodiment can be obtained.

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

  The specific numerical values such as the first predetermined time, the second predetermined time, the first predetermined value, the second predetermined value, and the time at which the processing is repeated are merely examples. The product specifications can be changed as needed.
