In the two-dimensional array, a plurality of keys constitute a plurality of rows 1, rows 2, rows 3, and rows 4 parallel to the X axis, and a plurality of columns 1, columns 2, and columns 3 parallel to the Y axis. Further, the numeric keypad 300 has a recess formed by the side surface (slope) of the dome of each key between adjacent keys. Between each column and each row of the two-dimensional array, a groove 302 in which these depressions are connected is formed. In the numeric keypad 300, the position of each key in the two-dimensional array is indicated by (X, Y) coordinates. This (X, Y) coordinate is hereinafter referred to as a key position.

The key operation is not limited to a finger, and a stylus may be used.

  When receiving a detection signal from each touch sensor, the operation receiving unit 130 determines the key position of the operated key based on the detection signal. Further, the operation receiving unit 130 determines the type of key operation based on the magnitude of the change in capacitance indicated by the detection signal. Here, in order to simplify the explanation, it is assumed that the type of key operation is either a pressing operation or a touch operation. The operation reception unit 130 outputs operation type data 131 indicating the determined key operation type and key position data 132 indicating the determined key position to the electrostatic key driver 140 (see FIG. 2).

  The timer unit 170 includes an alarm setting unit 171 that sets an alarm such as an alarm. The timer unit 170 controls the alarm setting unit 171 based on the control parameter. As a result, the timer unit 170 outputs an alarm through the speaker 200 or the like at the time set by the alarm setting unit 171.

  As described above, the operation receiving unit 130 includes the numeric keypad 300 including a plurality of keys and the touch pad 350. The memory 120 includes a ROM (Read Only Memory) that stores programs and data in a nonvolatile manner, a RAM (Random Access Memory) that stores programs and data in a volatile manner, and an HDD (Hard Disc Drive) that stores programs and data in a nonvolatile manner. ) Etc. The memory 120 stores mode data 121 indicating the current operation mode of the mobile phone 1 and control parameter information 122 (see FIG. 3). Details of the control parameter information 122 will be described later.

  The mobile phone 1 has a plurality of operation modes. In the present embodiment, the plurality of operation modes include, for example, a camera mode for shooting by the camera 180, a music player mode for outputting audio of music data from the speaker 200, and an alarm setting for outputting an alarm. Mode is included. The above-described mode data 121 indicates the current operation mode set in the mobile phone 1. The user can switch the operation mode of the mobile phone 1 by operating the operation reception unit 130.

  The electrostatic key driver 140 is a driver circuit for the operation receiving unit 130. The electrostatic key driver 140 controls the operation of the touch pad 350 of the operation receiving unit 130 and receives operation type data 131 and key position data 132 from the operation receiving unit 130. The electrostatic key driver 140 outputs a set of the operation type data 131 and the key position data 132 received together with the operation type data 131 to the CPU 110.

  When CPU 110 accepts a set of operation type data 131 and key position data 132 from electrostatic key driver 140, CPU 110 reads parameter data 126 (described later) from control parameter information 122 of memory 120 based on the set.

  In addition, the CPU 110 switches the operation mode of the mobile phone 1 based on the operation content of the user of the operation reception unit 130. The CPU 110 rewrites the mode data 121 in the memory 120 so as to indicate the operation mode after switching.

(Processing in camera mode)
FIG. 4 is a diagram showing an appearance of the mobile phone 1 together with an image displayed in the camera mode according to the first embodiment. In FIG. 4, for the sake of explanation, only the touch sensor groups 81, 82, and 83 corresponding to the columns 1, 2, and 3 are shown on the numeric keypad 300, and the touch sensor groups 91 to 94 for each row are shown. The illustration is omitted.

  When the operation mode of the mobile phone 1 is switched to the camera mode, the camera 180 starts photographing. Further, the CPU 110 rewrites the mode data 121 to indicate “camera mode”.

  The image processing unit 191 of the camera control unit 190 processes image data from the camera 180 based on control parameters (zoom magnification, exposure, ISO sensitivity) given from the CPU 110. An image based on the processed image data is displayed on the display unit 160 (see FIG. 4). Further, the camera control unit 190 displays the value of the control parameter from the CPU 110 together with the image on the display unit 160 (see FIG. 4).

  In the camera mode, the user can change the control parameters by operating the operation receiving unit 130. In the first embodiment, the operation for changing the type of the control parameter is an operation of touching a key in any one of the column 1, column 2 and column 3 of the numeric keypad 300. The operation for changing the value of the control parameter is a so-called slide operation. The slide operation is performed by moving a series of adjacent keys in any one of the columns 1, 2, and 3 with the finger touching the key (without releasing the finger from the key) or “upward” or “downward”. "(Refer to the thick dashed arrow in FIG. 4).

  The CPU 110 changes the value of the control parameter based on the operation content. The camera control unit 190 controls the image processing unit 191 based on the changed control parameter. The image processing unit 191 processes image data captured by the camera 180 based on the value of the control parameter.

  FIG. 5 is a flowchart for explaining the processing according to the first embodiment. The specific processing of the camera mode will be described with reference to FIG. 4 and according to the flowchart of FIG. Based on the mode data 121, the CPU 110 sets a table 123 whose identifier 124 indicates “camera mode” among the plurality of tables 123 of the control parameter information 122 as a search target.

  First, when the CPU 110 detects a touch operation of the numeric keypad 300 based on an input from the electrostatic key driver 140 (a combination of the operation type data 131 and the key position data 132) (YES in step S1), the CPU 110 becomes an object of the operation by the user. The type of control parameter (hereinafter referred to as operation target parameter) is selected (step S3).

  For example, it is assumed that the user performs a touch operation on the key “4” in row 1 (the key on which the numerical value “4” is printed). In step S <b> 3, the CPU 110 determines that the operation content is “touch operation” based on the input from the electrostatic key driver 140 (a combination of the operation type data 131 and the key position data 132).

  The CPU 110 searches the camera mode table 123 of FIG. 3 based on the key position data 132 from the electrostatic key driver 140. CPU 110 reads parameter data 126 (“zoom”) corresponding to data P1 corresponding to key position data 132 (key position of “4”) from table 123 based on the search result. As a result, the CPU 110 determines that the type of the operation target parameter is “zoom”. CPU 110 stores the determined type of control parameter (“zoom”) in memory 120.

  Thereafter, based on the input from the electrostatic key driver 140, the CPU 110 determines whether the key “4” has been pressed down following the touch operation (step S4). If CPU 110 determines that the “4” key has been pressed (YES in step S4), that is, if it is determined that the user operation is not an operation for setting a control parameter, the process proceeds to step S5. In step S <b> 5, the CPU 110 deletes the information related to the touch key detected in step S <b> 1, that is, the type of control parameter stored in the memory 120 in step S <b> 3 from the memory 120. The CPU 110 performs other processing in accordance with the pressing of the “4” key (step S7). Thereafter, the process returns to step S1.

  On the other hand, when CPU 110 determines that the key “4” is not pressed based on the input from electrostatic key driver 140 (NO in step S4), CPU 110 determines the direction of the slide operation in row 1 (step S4). S9, S13, S17).

  First, based on the input from the electrostatic key driver 140, the CPU 110 moves from the “4” key position detected in step S1 to the “upward” key position in the row 1 while performing a touch operation. Whether or not (step S9).

  When CPU 110 determines that the key position of the touch operation has moved “upward” in column 1 (YES in step S9), CPU 110 increases the value of the control parameter corresponding to column 1 (step S11). That is, the CPU 110 changes the value of the “zoom” control parameter stored in the memory 120 in step S1 to a value for changing the angle of view closer to the telephoto. The CPU 110 outputs the value of the control parameter after the change to the camera control unit 190. Thereafter, the process returns to step S1.

  The image processing unit 191 of the camera control unit 190 processes the image data from the camera 180 based on the changed control parameter (zoom magnification) value. An image based on the processed image data is displayed on the display unit 160 (see FIG. 4). In addition, the camera control unit 190 displays the value of the changed control parameter (zoom magnification) on the display unit 160 (see FIG. 4).

  On the other hand, when CPU 110 determines that the key position of the touch operation has not moved “upward” in column 1 (NO in step S9), CPU 110 determines that the key position based on the input from electrostatic key driver 140. Is moving in the “downward direction” in column 1 (step S13).

  When CPU 110 determines that the key position of the touch operation has moved “downward” in column 1 (YES in step S13), CPU 110 decreases the value of the control parameter (step S15). That is, the CPU 110 changes the value of the “zoom” control parameter stored in the memory 120 in step S1 to a value for changing the angle of view toward a wide angle. The CPU 110 outputs the value of the control parameter after the change to the camera control unit 190. Thereafter, the process returns to step S1.

  The camera control unit 190 controls the image processing unit 191 based on the value of the changed control parameter (zoom magnification). The image processing unit 191 processes the image data from the camera 180 according to the value of the control parameter. The processed wide-angle image is displayed on the display unit 160 (see FIG. 4). In addition, the camera control unit 190 displays the value of the changed control parameter (zoom magnification) on the display unit 160 (see FIG. 4).

  On the other hand, when CPU 110 determines that the key position of the touch operation has not moved “downward” in column 1 (NO in step S13), CPU 110 performs the touch operation based on the input from electrostatic key driver 140. It is determined whether or not the key position has moved to the next row 2 in the X-axis direction (step S17).

  If the CPU 110 determines that the key position data 132 indicates the key position in column 2 (YES in step S17), the CPU 110 changes the type of the operation target parameter (step S19). Thereafter, the process returns to step S4.

  Specifically, in step S <b> 19, the CPU 110 searches the camera mode table 123 of FIG. 3 based on the key position data 132. Based on the search result, the CPU 110 reads parameter data 126 (“exposure”) corresponding to the data P2 corresponding to the key position data 132 (for example, the key position “5” in column 2) from the table 123. Thereby, the CPU 110 determines that the type of the operation target parameter is “exposure”. CPU 110 deletes the type of operation target parameter (“zoom”) previously stored in memory 120, and stores the type of control parameter (“exposure”) determined in step S 19 in memory 120. Thereafter, the process returns to step S4.

  Thereafter, the processing after step S4 is performed in the same manner as in the case of “zoom” described above for the type “exposure” of the changed control parameter. That is, when the direction of the slide operation is “upward” in the column 2, the value of the control parameter is changed so that the degree of exposure of the captured image increases. Further, when the direction of the slide operation is “downward” in the column 2, the value of the control parameter is changed so that the degree of exposure of the captured image decreases.

  In step S17, if the CPU 110 determines that the key position data 132 from the electrostatic key driver 140 does not indicate the key position of column 2 (the key position of column 1 remains unchanged) (NO in step S17). ), The process returns to step S1. Thereafter, the processing after step S1 is performed in the same manner as described above.

  When it is determined that the touched key position corresponds to the column 3, the type of the operation target parameter is set (changed) to “ISO sensitivity”. When the slide operation direction is “upward” in the column 3, the value of “ISO sensitivity” is changed so that the ISO sensitivity of the captured image increases. When the direction of the slide operation is “downward” in the column 3, the value of “ISO sensitivity” is changed so that the ISO sensitivity of the captured image decreases.

  In FIG. 5, in order to change the type of the operation target parameter, the user only has to slide the finger to be touched to the adjacent column, and no special operation is required. The operation pattern for changing the operation target parameter is not limited to this operation pattern. For example, the keys in row 1 are touch-operated, and then the finger is once released from the numeric keypad 300. Thereafter, the operation pattern may be such that a key belonging to another column (column 2 or column 3) is touched again.

  Further, in FIG. 5, the value of the operation target parameter is variably determined by increasing / decreasing by the movement amount of the slide operation, that is, “upward” or “downward”. Further, the movement amount of the slide operation may include a distance (key position change, displacement) from the key position at the start of the slide operation to the key position at the end of the slide operation. The CPU 110 may determine the amount of increase or decrease in the value of the operation target parameter based on the magnitude of the distance (key position change, displacement).

In the case of an artist name, for example, “Taro”, “Jiro Yamada”, “Sato” and the like are shown. In the case of an album title, for example, “ntemps”, “ete”, “autom”, and the like are indicated. The reproduction position indicates the address position from the beginning of the music data when the music data has a predetermined data size (unit: Byte).

  The CPU 110 changes the type or value of the control parameter based on the operation content of the numeric keypad 300. The audio output control unit 210 controls the audio reproduction unit 211 based on the control parameter given from the CPU 110.

  FIG. 7 is a flowchart for explaining processing in the music player mode according to the second embodiment. 7 differs from the processing in FIG. 5 in that, in FIG. 7, the slide operation in the “left direction” and “right direction” of the X axis of each row is determined in steps S9a and S13a. In step S17a, the key position is determined to move to a line adjacent in the Y-axis direction, and in steps S11a, S15a, and S19a, the value of the operation target parameter corresponding to the touch-operated line is increased or decreased. Since other processes are the same as those in FIG. 5, description thereof will not be repeated.

  Regarding the above differences, the table 123 (not shown) corresponding to the music player mode has, as position data 125, data P1 indicating the key position of each key in row 1 and data indicating the key position of each key in row 2. P2, data P3 indicating the key position of each key in row 3, and data P4 indicating the key position of each key in row 4 are included. The parameter data 126 includes the types of control parameters corresponding to the data P1 to P4. In the case of the music player mode, the type of control parameter corresponding to the data P1 is “artist name”, the type of control parameter corresponding to the data P2 is “album title”, and the type of control parameter corresponding to the data P3 is “ The type of the control parameter corresponding to the “music title” and the data P4 is “playback position”.

  As described above, also in the music player mode, as in the camera mode of the first embodiment, the user can select the operation target parameter by touching the key in any one of the rows 1 to 4. . Further, the user can change the value of the operation target parameter by sliding the finger in the “left direction” and the “right direction” in the row.

  Specifically, when the operation target parameter is “artist name”, the current value (Jiro) is changed to “Taro” by the “left” slide operation, and the “right” slide operation is performed by the “right” slide operation. The current value (Jiro) is changed to “Sato”. Similarly, when the operation target parameter is “album title”, the current value (ete) is changed to “ntemps” by the “left” slide operation, and the current value is changed by the “right” slide operation. The value (ete) is changed to “autom”. Similarly, when the operation target parameter is “song title”, the “left” slide operation changes the current value (summer landscape) to “scenery”, and the “right” slide operation The current value (summer scenery) is changed to “autumn scenery”.

  In addition, when the operation target parameter is “playback position”, a “leftward” slide operation is used to change (rewind) from the current playback position to the beginning position. By the slide operation, the current playback position is changed to advance (fast forward). In FIG. 6, the playback position is indicated by a bar graph G on the screen. The length of the bar graph G along the X-axis direction changes in conjunction with the slide operation. The user confirms that the playback position has been changed by the change in the length of the bar graph G.

[Embodiment 3]
The third embodiment is a modification of the first and second embodiments. In the third embodiment, processing when the operation mode of the mobile phone 1 described in the first and second embodiments is an alarm setting mode will be described. In Embodiment 3, the configuration of mobile phone 1 and the function of each part are the same as in Embodiment 1, and description thereof will not be repeated.

  FIG. 8 is a diagram showing an appearance of the mobile phone 1 together with an image displayed in the alarm setting mode according to the third embodiment. In FIG. 8, for the sake of explanation, only the touch sensor groups 91, 92, 93, and 94 corresponding to row 1, row 2, row 3, and row 4 are shown on the numeric keypad 300, and the touches for the respective columns are shown. The sensor groups 81 to 83 are not shown.

  When the operation mode of the mobile phone 1 is switched to the alarm setting mode, the CPU 110 rewrites the mode data 121 to indicate “alarm setting mode”.

  The CPU 110 displays information for alarm setting on the display unit 160 via the display driver 150 in accordance with the mode data 121. This information includes numerical values in units of “hour” and “minute” representing the set alarm time (see FIG. 8). In the third embodiment, each unit of “hour” and “minute” of the alarm time corresponds to the control parameter, and the value of each unit corresponds to the value of the control parameter. The timer unit 170 controls the alarm setting unit 171 based on these control parameters.

  The user can change the above control parameters by operating the operation reception unit 130 in the alarm setting mode. In the third embodiment, the operation for changing the type of the control parameter is a touch operation of any one of the row 1, row 2, row 3, and row 4 keys of the numeric keypad 300. Further, the operation for changing the value of the control parameter is a sliding operation in the “left direction” or “right direction” (see the thick broken line arrow in FIG. 8) in any of the lines 1 to 4. .

  When the type of the control parameter is “hour”, the value of the control parameter includes a tens place value and a tens place value. If the type of the control parameter is “minute”, the value of the control parameter is a tens place value and a tens place value.

  The CPU 110 determines the type or value of the operation target parameter based on the input from the electrostatic key driver 140 (operation type data 131, key position data 132). For example, when a sliding operation is performed in the vertical direction in the row 1, the tens place value of “hour” is increased or decreased. In addition, when a vertical slide operation is performed in row 2, the value of the first place of “hour” is increased or decreased. Further, when a sliding operation is performed in the vertical direction in the row 3, the tenth digit value of “minute” is increased or decreased. In addition, when a sliding operation is performed in the vertical direction in the row 4, the value of the first place of “minute” is increased or decreased. The timer unit 170 controls the alarm setting unit 171 based on the control parameter from the CPU 110.

  As described above, also in the alarm setting mode, as in the camera mode of the first embodiment or the music player mode of the second embodiment, the user performs a touch operation on a key in any one of the rows 1 to 4. An operation target parameter can be selected. In addition, the user can change (increase or decrease) the value of the operation target parameter by performing a “leftward” or “rightward” sliding operation in a row.

  In each of the embodiments described above, the detection method using the touch sensor of the touch pad 350 is a method of detecting a change in capacitance, but is not limited to this detection method. For example, the touch sensor of the touch pad 350 may be a method that detects a change in pressure according to a touch operation or a push-down operation. Even if the touch pad 350 detects a change in pressure, the configurations and functions of the above-described embodiments can be realized.

[Effect of the embodiment]
In each embodiment, when the user performs a sliding operation on the numeric keypad 300, the user can feel the groove 302 formed between each row and between each column with a finger. Thereby, in the slide operation, it can be recognized from the touch that the key position has moved to the adjacent row / column. Moreover, the user can grasp a row and a column to be operated and perform a desired slide operation without moving the line of sight to the numeric keypad 300 by the touch.

  In the structure, touch sensor groups 81 to 83 and 91 to 94 corresponding to a plurality of one-dimensional electrostatic pads are installed in each column or each row of the numeric keypad 300 on the back side of the numeric keypad 300. Therefore, even when the static electricity detection unit cannot be provided on the screen of the display unit 160, an intuitive operation by a touch operation and a slide operation using the touch sensor groups 81 to 83 and 91 to 94 can be performed. .

  In addition, in order to input information to the mobile phone 1, a pointer is displayed on the screen, and instead of the key operation for moving the pointer, the touch sensor groups 81 to 83, 91 to 1 described in the first to third embodiments are used. The touch operation and slide operation using 94 can be provided.

  In the control, the CPU 110 can determine the type of the control parameter assigned to each column or each row of the numeric keypad 300 via the table 123. Further, the CPU 110 determines which row and column are operated (touch operation, slide operation) based on the input (operation type data 131 and key position data 132) from the electrostatic key driver 140. be able to. Therefore, the CPU 110 can accurately determine and change the type and value of the operation target parameter based on the operation content for the user's information input to the mobile phone 1.

  In each embodiment, a slide operation in each row and each column is provided instead of a UI (user interface) such as the slider device of Patent Document 1. The user can input different control parameters to the mobile phone 1 for each operation mode of the mobile phone 1 by the same sliding operation. Thereby, while sharing the installation space of the operation reception unit 130 of the mobile phone 1 with the installation space of the numeric keypad 300, that is, without requiring a dedicated installation space, a plurality of types of control can be performed on the mobile phone 1. Values can be entered for parameters.

  Therefore, even in an electronic device such as the mobile phone 1 that is limited in that the installation space of the operation reception unit 130 is narrow, a lot of information including the types and values of the control parameters as shown in each embodiment. Can be installed.
