When this condition is satisfied, a single designated position is determined based on the first detection position and the second detection position. Even when the user instructs the display surface of the first display means and the display surface of the second display means simultaneously with one finger, it can be determined that the instruction is made with one finger. In addition, when the first detection position and the second detection position do not satisfy the predetermined condition, a single designated position is not determined from the first detection position and the second detection position, so two fingers It can be judged as an instruction by.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

  In the present embodiment, a mobile communication terminal 1 will be described as an example of an input device. The form communication terminal 1 changes form between an open state and a closed state. FIG. 1A is a perspective view of the mobile communication terminal in a closed state. FIG. 1B is a perspective view of the mobile communication terminal in the open state. 1A and 1B, mobile communication terminal 1 slides first display device 2, second display device 3, first display device 2, and second display device 3. And a housing portion 5 that is supported. Note that the housing unit 5 may have a connection structure that allows the first display device and the second display device 3 to slide, and may be, for example, a slidable arm. Both the first display device 2 and the second display device 3 are substantially rectangular parallelepipeds. The casing 5 includes a recess. When the casing 5 is in the closed state, the first display device 2 and the second display device 3 are accommodated in the recess, and the mobile communication terminal 1 is substantially a rectangular parallelepiped. Therefore, the mobile communication terminal 1 in the closed state has a shape suitable for a call.

  The speaker 11 and the microphone 13 are arranged at positions different from the concave portion in which the first display device 2 and the second display device 3 of the housing unit 5 are accommodated. For this reason, when the portable communication terminal 1 is in the closed state, the speaker 11 and the microphone 13 are exposed. Note that the speaker 11 and the microphone 13 may be provided on the surface of the first display device 2 exposed in the closed state, or may be provided on the surface of the second display device 3.

  In the closed state, the first display device 2 overlaps the second display device 3. The first display device 2 includes a first liquid crystal display device (LCD) 15 on the front side opposite to the surface overlapping the second display device 3, and a first touch panel 17 is provided so as to overlap the first LCD 15. The second display device 3 includes a second LCD 16 on a surface overlapping with the first display device 2, and a second touch panel 18 is provided so as to overlap the second LCD 16.

  In the closed state, the first display device 2 overlaps the second display device 3, so the first LCD 15 is exposed, but the second LCD 16 is covered by the first display device 2. For this reason, when the mobile communication terminal 1 is in the closed state, the user can touch the first touch panel 17 but cannot touch the second touch panel 18.

  When the first display device 2 and the second display device 3 of the mobile communication terminal 1 in the closed state slide, the mobile communication terminal 1 enters the open state. The second display device 3 slides in a direction opposite to the direction in which the first display device 2 slides. The second display device 3 is biased by a spring provided in the housing unit 5 and is lifted upward when it slides to a predetermined position. Therefore, as shown in FIG. 1B, when the mobile communication terminal 1 is in the open state, the display surface of the first LCD 15 included in the first display device 2 and the display surface of the second LCD 16 included in the second display device 3 are separated. Located on the same plane. Therefore, when the mobile communication terminal 1 is in the open state, the first LCD 15 and the second LCD 16 are both displayed, so that the user can see the images displayed on them. Since the screen area is doubled compared to when the mobile communication terminal 1 is in the closed state, a large amount of information can be displayed. Furthermore, since the first touch panel 17 provided to be superimposed on the first LCD 15 and the second touch panel 18 provided to be superimposed on the second LCD 16 are also displayed, the user can input an instruction in a wide area.

  In addition, when the mobile communication terminal 1 is in the open state, an intermediate band that cannot display an image is formed between the first LCD 15 and the second LCD 16, and the first LCD 15 and the second LCD 16 do not form a complete screen.

  Further, when the mobile communication terminal 1 is in the open state, the speaker 11 and the microphone 13 are exposed. For this reason, it is possible to talk, but the first display device 2 and the second display device 3 protrude from the housing 5 and are double the display surface when the display surface is in the closed state. Is a shape that is not suitable for holding a phone call. For this reason, when the mobile communication terminal 1 is in the open state, the shape is suitable for displaying an image or inputting an operation by the user.

  The radio circuit 22 receives the radio signal received by the antenna 22A, and outputs a signal obtained by demodulating the radio signal to the CPU 21. When the signal obtained by demodulating the radio signal is an audio signal, the CPU 21 outputs the audio signal to the codec unit 28. When a signal is input from the CPU 21, the wireless circuit 22 outputs a wireless signal obtained by modulating the signal to the antenna 22A. When the audio signal is input from the codec unit 28, the CPU 21 outputs the audio signal to the wireless circuit 22. When receiving the incoming call, the radio circuit 22 outputs an incoming call signal to the CPU 21. When a call signal is input from the CPU 21, the call is sent to the telephone number input from the CPU 21.

  The codec unit 28 decodes the audio signal input from the CPU 21, converts the decoded digital audio signal into analog, amplifies it, and outputs it to the speaker 11 as a receiver. The codec unit 28 receives an analog audio signal from the microphone 13, converts the audio signal to digital, encodes it, and outputs the encoded audio signal to the CPU 21.

  The open sensor 23 is turned on when the state of the mobile communication terminal 1 is in the open state, and is turned off when not in the open state. The close sensor 24 is turned on when the state of the mobile communication terminal 1 is closed, and is turned off when not in the closed state. The open sensor 23 and the close sensor 24 are connected to the CPU 21, and the CPU 21 detects the states of the open sensor 23 and the close sensor 24, thereby detecting the form of the mobile communication terminal 1. Here, the open sensor 23 and the close sensor 24 detect the position of the first display device 2.

  When an operation is input from the operation unit 25, the CPU 21 executes a process according to the input operation. The CPU 21 reads and executes a plurality of application programs stored in the flash memory 31. These application programs are described in a program language such as C language or JAVA (registered trademark), but the program language in which the application program is described is not limited thereto, and is described in any other program language.

That is, application programs described in a plurality of program languages may be mixed.

  The first LCD 15 and the second LCD 16 are controlled by the CPU 21 and display images. Instead of the first LCD 15 and the second LCD 16, for example, an organic EL (Electro-Luminescence) display may be used as long as the device displays an image.

  The operation unit 25 includes a first touch panel 17 provided to be superimposed on the first LCD 15 and a second touch panel 18 provided to be superimposed on the second LCD 16. Here, the first touch panel 17 and the second touch panel 18 are of a capacitance type, and can detect a position designated by a user with a finger. When the user touches the panel surface with a finger or the like, the first touch panel 17 and the second touch panel 18 detect a position touched by the finger or the like. The first touch panel 17 and the second touch panel 18 each output position information indicating the detected position to the CPU 21. When the user touches the first touch panel 17 or the second touch panel 18 with a finger, the first touch panel 17 or the second touch panel 18 detects an area in contact with the finger or an area in which the finger is approaching. The first touch panel 17 or the second touch panel 18 outputs position information including coordinates of the center of gravity of the detected area (hereinafter referred to as “detection position”) and the area of the area to the CPU 21. When the user touches the first touch panel 17 or the second touch panel 18 with a plurality of fingers, the first touch panel 17 or the second touch panel 18 detects a plurality of areas and outputs position information corresponding to each of the plurality of areas to the CPU 21. . Here, the position information output from the first touch panel 17 is referred to as first position information, and the position information output from the second touch panel 18 is referred to as second position information. The detection position included in the first position information is referred to as a first detection position, and the detection position included in the second position information is referred to as a second detection position. The first touch panel 17 and the second touch panel 18 may be other methods, for example, a resistive film method, an electromagnetic induction method, a surface acoustic wave method, and the like, as long as the position and area touched by a user can be detected. An infrared method may be used.

  A removable memory card 27A is attached to the card I / F 27. The memory card 27A is, for example, a CompactFlash, a SmartMedia (registered trademark), an SD (Secure Digital) memory card, a memory stick, an MMC (MultiMedia Card), an xD picture card, or the like.

The CPU 21 can access the memory card 27A via the card I / F 27. Although an example in which a program to be executed by the CPU 21 is stored in the flash memory 31 will be described here, the program is stored in the memory card 27A, the program is read from the memory card 27A, and is executed by the CPU 21. You may do it. The recording medium for storing the program is not limited to the memory card 27A, but a flexible disk, cassette tape, magnetic disk, optical disk (CD-ROM (Compact Disc).

Alternatively, the mobile communication terminal 1 may be connected to the Internet via the wireless circuit 22 and a program may be downloaded from a computer connected to the Internet and executed by the CPU 21. The program here includes not only a program directly executable by the CPU 21 but also a source program, a compressed program, an encrypted program, and the like.

  FIG. 3 is a diagram illustrating an example of a positional relationship between the first touch panel and the second touch panel in the open state. Referring to FIG. 3, in the open state, first touch panel 17 and second touch panel 18 are arranged side by side with intermediate band 75 interposed therebetween. The display surfaces of the first touch panel 17 and the second touch panel 18 are substantially the same plane.

  The first touch panel 17 includes a first range 71 within a predetermined distance D1 from the intermediate band 75. In the figure, the first range 71 is indicated by hatching, but there is actually no hatching. The second touch panel 18 includes a second range 73 within a predetermined distance D1 from the intermediate band 75. In the figure, the second range 73 is indicated by hatching, but there is actually no hatching. The predetermined distance D1 is a maximum value that can be assumed when the user instructs both the first touch panel 17 and the second touch panel 18 with one finger. Here, the width of the intermediate band 75 (distance between the first touch panel 17 and the second touch panel 18) is set to 0.8 cm, the maximum length of the area touching the plane with one finger is set to 2 cm, and the first range 71 The width of the second range 73 is 1.2 cm (= 2−0.8).

  A separate coordinate system is set for each of the first touch panel 17 and the second touch panel 18. The coordinate system set on the first touch panel 17 is the origin O1, the horizontal direction in the figure is the X axis, and the vertical direction is the Y axis. The coordinate system set on the second touch panel 18 is the origin O2, the horizontal direction in the figure is the X axis, and the vertical direction is the Y axis.

  In the open state, an overall coordinate system is set by combining the individual coordinate system set on the first touch panel 17 and the individual coordinate system set on the second touch panel 18. Here, the global coordinate system is the origin O1, the horizontal direction in the figure is the X axis, and the vertical direction is the Y axis. For this reason, the coordinates of the individual coordinate system set on the first touch panel 17 are the same as the coordinates of the entire coordinate system, but the coordinates of the individual coordinate system set on the second touch panel 18 are the Y coordinates in the entire coordinate system. Are the same, but the X coordinate is a value obtained by adding the horizontal width D4 of the first touch panel 17 and the intermediate band D2. Thereby, the CPU 21 can process the first detection position input from the first touch panel 17 and the second detection position input from the second touch panel 18 in one global coordinate system.

  Mobile communication terminal 1 in the present embodiment can individually input instructions to first touch panel 17 and second touch panel 18 in the open state. In addition, the first touch panel 17 and the second touch panel 18 are arranged with the intermediate band 75 sandwiched between them in the open state, but there are cases where both the first touch panel 17 and the second touch panel 18 are touched with one finger. . Moreover, if it is an electrostatic capacitance type touch panel, even if it is a case where it adjoins, both the 1st touch panel 17 and the 2nd touch panel 18 may be touched with one finger | toe. For example, it is a case where a finger is slid from the state in which only the first touch panel 17 is instructed to move to the second touch panel 18 side. Since each of the first touch panel 17 and the second touch panel 18 outputs position information to the CPU 21, the CPU 21 outputs the first position information output from the first touch panel 17 even though the user is pointing with one finger. In some cases, it may be determined that two positions are detected from the second position information output from the second touch panel 18. On the other hand, the user may instruct each of the first touch panel 17 and the second touch panel 18 with two fingers. Therefore, when the first position information and the second position information are input at the same time, the CPU 21 needs to determine whether the instruction is made with one finger or the two fingers. Hereinafter, the process which CPU21 performs this judgment is demonstrated.

  FIG. 4 is a functional block diagram showing an outline of functions of the CPU 21 provided in the mobile communication terminal 1. Referring to FIG. 4, the CPU 21 detects a position designated by the user on the first touch panel, a first position detection unit 41 that detects a position designated by the user on the second touch panel, and The detection positions detected by the first display unit 45 that controls the first LCD 15, the second display unit 47 that controls the second LCD 16, and the first position detection unit 41 and the second position detection unit 43 satisfy a predetermined condition. A determination unit 46 that determines whether or not, and an instruction position determination unit 63 that determines an instruction position based on two detection positions that satisfy a predetermined condition based on the determination result.

  The first position detection unit 41 is connected to the first touch panel 17 and acquires first position information output from the first touch panel 17 at predetermined time intervals. The first position detection unit 41 outputs the first position information acquired from the first touch panel 17 to the determination unit 46. When the user touches the first touch panel 17 with a plurality of fingers, the first touch panel 17 outputs a plurality of first position information. Therefore, the first position detection unit 41 receives the plurality of first position information from the first touch panel 17. The plurality of pieces of first position information are acquired and output to the determination unit 46.

  The second position detection unit 43 is connected to the second touch panel 18 and acquires second position information output from the second touch panel 18 at predetermined time intervals. The second position detection unit 43 outputs the second position information acquired from the second touch panel 18 to the determination unit 46. When the user touches the second touch panel 18 with a plurality of fingers, the second touch panel 18 outputs a plurality of second position information. Therefore, the second position detection unit 43 receives the plurality of second position information from the second touch panel 18. The plurality of pieces of second position information are output to the determination unit 46.

  The determination unit 46 receives the detection position detected by the first position detection unit 41 and the detection position detected by the second position detection unit 43, and determines whether they satisfy a predetermined condition. The determination unit 46 includes a set generation unit 49 and an extraction unit 53. The set generation unit 49 includes a first detection position included in the first position information input from the first position detection unit 41 and a second detection position included in the second position information input from the second position detection unit 43. And generate a pair. When one or more first position information is input and one or more second position information is input, the set generation unit 49 selects one selected from one or more first detection positions and one or more second detection positions. A pair is generated with one selected from the above. Here, the set generation unit 49 generates a plurality of sets of the first detection position and the one or more second detection positions for each of the one or more first detection positions. For example, if the number of first detection positions is N (N is a positive integer) and the number of second detection positions is M (M is a positive integer), N × M sets are generated.

  The set generation unit 49 includes a range limiting unit 51. The range limiter 51 sets a range limit set by a first detection position included in the first range 71 of the first detection positions and a second detection position included in the second range 73 of the second detection positions. Generate. When there are one or more first detection positions included in the first range 71 and one or more second detection positions included in the second range 73, the range limiting unit 51 is included in the first range 71. A range restriction set is generated by one selected from the first detection positions and one selected from one or more second detection positions included in the second range 73. Here, for each of one or more first detection positions included in the first range 71, the range limiting unit 51 generates a plurality of sets with the first detection position and each of the one or more second detection positions. For example, if the number of first detection positions included in the first range 71 is N1 (N1 is a positive integer) and the number of second detection positions included in the second range 73 is M1 (M1 is a positive integer), N1 × M1 range restriction sets are generated. The range restriction unit 51 outputs the generated range restriction pair to the extraction unit 53.

  The range limiter 51 sets a range limit set by a first detection position included in the first range 71 of the first detection positions and a second detection position included in the second range 73 of the second detection positions. Since they are generated, there are cases where the number of sets generated is smaller than the sets generated at all of the first detection positions and the second detection positions. For this reason, since the number of sets to be processed decreases in the extraction unit 53 described later, the load can be reduced and the processing speed can be increased.

  The extraction unit 53 extracts a condition set from the range restriction set and outputs the condition set to the designated position determination unit 63. The extraction unit 53 includes a length restriction set extraction unit 55, an overlapping set extraction unit 57, a condition set extraction unit 59, and a selection unit 61.

  The length restriction set extraction unit 55 extracts a restriction set whose distance between detection positions is equal to or less than a predetermined length TL from the range restriction set, and uses the extracted length restriction set as the duplicate set extraction unit 57 and the condition set. The data is output to the extraction unit 59. Specifically, the length restriction set extraction unit 55 calculates the distance between the first detection position and the second detection position included in each range restriction set, and the distance is equal to or less than the predetermined length TL. In this case, the range restriction pair is extracted as a length restriction pair. When the first detection position and the second detection position are input from the first position detection unit 41 and the second position detection unit 43, respectively, the first detection position and the second detection position are designated with one finger. May be detected by the first position detection unit 41 and the second position detection unit 43, respectively. The predetermined length TL is the maximum length of a region where one finger touches the plane. The predetermined length TL may be a predetermined value. For example, the length of a person's finger belly is obtained by statistical processing. Here, the predetermined length TL is 2 cm. Further, the predetermined length TL may be determined by statistically processing the area included in the position information detected by each of the first touch panel 17 and the second touch panel 18. Thereby, the predetermined length TL can be determined according to the size of the user's finger.

  When a plurality of length restriction pairs are extracted from a plurality of range restriction pairs, the length restriction pair extraction unit 55 outputs all of them to the duplicate set extraction unit 57 and the condition group extraction unit 59.

  When a plurality of length restriction sets are input from the length restriction set extraction unit 55, the duplicate set extraction unit 57 extracts a plurality of duplicate sets from the plurality of length restriction sets. An overlapping set refers to a two or more length limit set in which either one of the first detection position and the second detection position is the same. A set of two or more overlapping sets having the same one of the first detection position and the second detection position is called an overlapping set group. The plurality of overlapping groups extracted by the overlapping group extraction unit 57 may form a plurality of overlapping group groups. For example, an overlapping group group composed of a plurality of overlapping groups having the same first detection position and an overlapping group group composed of a plurality of overlapping groups having the same first detection position may be formed. When extracting a plurality of overlapping sets from a plurality of length restriction pairs, the overlapping set extraction unit 57 outputs the extracted plurality of overlapping sets to the selection unit 61 and the condition set extraction unit 59 for each overlapping set group.

  The selection unit 61 selects one shortest set from among a plurality of overlapping sets, and outputs the selected shortest set to the condition set extraction unit 59. The shortest pair is an overlapping pair having a shortest distance between the first detection position and the second detection position among a plurality of overlapping sets. When a plurality of overlapping sets are input from the overlapping set extraction unit 57, the selection unit 61 calculates the distance between the first detection position and the second detection position for each of the plurality of overlapping sets, and the calculated distance is the smallest. Are selected as the shortest pair. The selection unit 61 outputs the selected shortest set as a condition set to the condition set extraction unit 59. When the plurality of overlapping sets input from the overlapping set extraction unit 57 forms a plurality of overlapping set groups, the selection unit 61 selects the shortest set for each of the plurality of overlapping set groups. Therefore, the same number of condition groups as the overlapping group are output to the condition group extraction unit 59.

  The condition set extraction unit 59 receives the length limit set from the length limit set extraction unit 55, receives the duplicate set from the duplicate set extraction unit 57, and receives the condition set from the selection unit 61. The condition set extraction unit 59 extracts a non-overlapping set from the length limit sets as a condition set. The condition group extraction unit 59 outputs the condition group that is not an overlapping group among the length restriction groups and the condition group that is input from the selection unit 61 to the designated position determination unit 63.

  When the condition set is input from the extraction unit 53, the indicated position determination unit 63 determines one indicated position based on the first detection position and the second detection position included in the condition set. Specifically, the designated position determination unit 63 determines one of the first detection position and the second detection position included in the condition set received from the condition set extraction unit 59 as the designated position. Here, the area of the region included in the first position information together with the first detection position is compared with the area of the region included in the second position information together with the second detection position, and among the first detection position and the second detection position, The larger area of the corresponding region is determined as the designated position. In addition, the designated position determination unit 63 determines a detection position that is neither the first detection position nor the second detection position included in the condition group among the detection positions input from the set generation unit 49 as the designated position.

  Here, the indication position determination unit 63 has shown an example in which one of the first detection position and the second detection position included in the condition set received from the condition set extraction unit 59 is determined as the indication position. A point on a straight line connecting the first detection position and the second detection position may be determined as the designated position based on the area ratio.

  FIG. 5 is a flowchart illustrating an example of the flow of the designated position determination process. The designated position detection process is a process executed by the CPU 21 when the CPU 21 executes the designated position detection program stored in the flash memory 31. Referring to FIG. 5, CPU 21 determines whether or not a detection position has been received (step S01). If the first position information output from the first touch panel 17 or the second position information output from the second touch panel 18 is received (NO in step S01), and if at least one of them is received ( In step S01, YES), the process proceeds to step S02.

  In step S02, it is determined whether or not there are a plurality of detection positions accepted in step S01. If a plurality of detection positions are accepted, the process proceeds to step S03. If not, the process proceeds to step S25.

  In step S03, among the plurality of detection positions received in step S01, a detection position indicating a position other than the first or second range 71, 73 is set as the designated position. This is because detection positions that do not indicate either the first range 71 or the second range 73 are likely to indicate positions designated by one finger. The first range 71 and the second range 73 are preset ranges. As shown in FIG. 3, the horizontal width D1 of each of the first range 71 and the second range 73 is determined when the user indicates both the first touch panel 17 and the second touch panel 18 with one finger. This is the maximum value that can be assumed.

  In the next step S04, it is determined whether or not there is a detection position indicating any position in the first range 71 and the second range 73 among the plurality of detection positions received in step S01. To do. If such a detection position exists (YES in step S04), the process proceeds to step S05. If not (NO in step S04), the process proceeds to step S25.

  When the processing proceeds to step S05, the processing after step S05 is a processing position that is determined to indicate any position in the first range 71 and the second range 73 in step S04. Since the number of detection positions to be processed is limited, the processing speed can be increased. In step S05, one or more first detection positions indicating positions in the first range 71 of the first touch panel 17 are set in the first group, and the process proceeds to step S06. In step S06, one or more second detection positions indicating positions within the second range 73 of the second touch panel 18 are set in the second group, and the process proceeds to step S07.

  In step S07, it is determined whether or not position information is included in both the first group and the second group. If position information is included in both the first group and the second group, the process proceeds to step S08. If not, the process proceeds to step S25. This is because when the first touch panel 17 and the second touch panel are simultaneously touched with one finger, the detection positions are detected in the first range 71 and the second range 73, respectively.

  In step S08, one of the one or more first detection positions included in the first group is set as a processing target, and the process proceeds to step S09. In step S09, one of one or more second detection positions included in the second group is set as a processing target, and the process proceeds to step S10. In step S10, a set including the first detection position set as the processing target in step S08 and the second detection position set as the processing target in step S09 is generated, and the process proceeds to step S11. The set generated at this time is a range-restricted set including a first detection position indicating a position in the first range 71 and a second detection position indicating a position in the second range 73.

  In step S11, a distance L between the first detection position and the second detection position constituting the range restriction set generated in step S10 is calculated, and the process proceeds to step S12. In step S12, it is determined whether or not the distance L is less than or equal to the threshold value TL. The threshold value TL is equal to the predetermined length TL described above. If distance L is less than or equal to threshold value TL, the process proceeds to step S13. If not, step S13 is skipped and the process proceeds to step S14. In step S13, the range restriction pair generated in step S10 is set as a length restriction pair, and the process proceeds to step S14.

  In step S14, it is determined whether there is a second detection position that has not yet been set as a processing target among the second detection positions set in the second group. If there is an unprocessed second detection position, the process returns to step S09; otherwise, the process proceeds to step S15.

  In step S15, it is determined whether there is a second detection position that has not yet been set as a processing target among the first detection positions set in the first group. If there is an unprocessed second detection position, the process returns to step S08, and if not, the process proceeds to step S16. In step S16, it is determined whether or not one or more length restriction pairs are set in step S13. If one or more length restriction pairs are set, the process proceeds to step S17. If not, the process proceeds to step S25.

  In step S17, it is determined whether or not there is an overlapping pair among the one or more length restriction pairs. If there is an overlapping group, the process proceeds to step S18. If there is no overlapping group, the process proceeds to step S21. In step S18, an overlapping group is selected, and the process proceeds to step S19. One overlapping group to be processed is selected from a plurality of overlapping group groups. If there is one overlapping group, that overlapping group is selected. In the next step S19, the shortest group is set as the condition group among the plurality of overlapping groups belonging to the selected overlapping group, and the process proceeds to step S20. The shortest group is an overlapping group having the shortest distance between the first detection position and the second detection position among a plurality of overlapping groups belonging to the same overlapping group group. In the next step S20, it is determined whether or not there is an overlapping set group that has not yet been selected as a processing target. If there is an unprocessed overlapping group, the process returns to step S18. If not, the process proceeds to step S22. Therefore, when there are a plurality of overlapping group groups, one condition group is set for each of the plurality of overlapping group groups, and the same number of condition groups as the overlapping group groups are set.

  On the other hand, in step S21, all of the length restriction groups set in step S13 are set as condition groups, and the process proceeds to step S22.

  In step S22, one of the condition groups set in step S19 or step S21 is selected as a processing target, and the process proceeds to step S23. In step S23, one of the first detection position and the second detection position included in the condition set selected as the processing target is determined as the designated position, and the process proceeds to step S24. In step S24, it is determined whether there is a condition set that has not yet been selected as a processing target. If there is an unprocessed condition set (YES in step S24), the process returns to step S22, and if not, the process proceeds to step S25. That is, when a plurality of condition sets exist, one designated position is determined for each of the plurality of condition sets.

  In step S25, a detection position other than the condition set is set as the designated position, and the process ends. When the process proceeds from step S02, step S04, step S07, or step S16, since the condition set is not set, all of the one or more detection positions accepted in step S01 are set as designated positions. When the process proceeds from step S24, since one or more condition sets are set, all of the detection positions received in step S01 except for the detection positions constituting the condition set are determined as indicated positions. To do. The designated position corresponding to the condition set is already set in step S23.

  FIG. 6 is a diagram illustrating an example when the detection position is detected by each of the first touch panel and the second touch panel. Referring to FIG. 6, region 77 indicates a region where the user touches first touch panel 17, second touch panel 18, and intermediate band 75 simultaneously with one finger. In this case, the first touch panel 17 detects the region 81 and outputs the first detection position P11 that is the coordinates of the center of gravity of the region 81 and the area of the region 81 to the CPU 21. Further, the second touch panel 18 detects the region 83 and outputs the second detection position P21 that is the coordinates of the center of gravity of the region 83 and the area of the region 83 to the CPU 21. The first detection position P11 is located in the first range 71, and the second detection position P21 is located in the second range 73. Therefore, the group composed of the first detection position P11 and the second detection position P21 is a range restriction group. Here, L11 <length TL. For this reason, the group comprised by the 1st detection position P11 and the 2nd detection position P21 is extracted as a condition group. Further, here, the area of the region 81> the area of the region 83, and the detection position P11 is determined as the detection position.

  FIG. 7 is a first diagram illustrating an example when a plurality of detection positions are detected on each of the first touch panel and the second touch panel. Referring to FIG. 7, regions 77A and 77B each indicate a region where the user touches first touch panel 17, second touch panel 18, and intermediate band 75 simultaneously with one finger. An area 77C indicates an area where the user touches the second touch panel 18 and the intermediate band 75 simultaneously with one finger. In this case, the first touch panel 17 detects the area 81A and the area 81B represented by oblique lines, the first detection position P11 and the area of the area 81A, which are the coordinates of the center of gravity of the area 81A, and the coordinates of the center of gravity of the area 81B. The first detection position P12 and the area of the region 81B are output to the CPU 21.

  Further, the second touch panel 18 detects the areas 83A, 83B, and 83C represented by diagonal lines, and the second detection position P21 that is the coordinates of the center of gravity of the area 83A, the area of the area 83A, and the coordinates of the center of gravity of the area 83B. The area of the second detection position P22 and the area 83B and the second detection position P23 and the area of the area 83C, which are the coordinates of the center of gravity of the area 83C, are output to the CPU 21.

  The first detection positions P11 and P12 are located in the first range 71, and the second detection positions P21, P22, and P23 are located in the second range 73.

  In this case, three range-limitation groups each composed of the first detection position P11 and the three second detection positions P21, P22, and P23, and the first detection position P12 and the three second detection positions P21, P22, P23, With each P23, three range restriction sets configured are generated.

  On the other hand, of the three range restriction groups configured by the first detection position P11 and the three second detection positions P21, P22, and P23, the range configured by the first detection position P11 and the second detection position P21. Since the distance between the first detection position and the second detection position is equal to or less than the length TL, the restriction group and the range restriction group constituted by the first detection position P11 and the second detection position P22 are limited in length. Furthermore, since each length restriction pair includes the same first detection position P11, it is an overlapping pair. Here, the distance L11 between the first detection position P11 and the second detection position P21 is shorter than the distance L12 between the first detection position P11 and the second detection position P22. The length limit set composed of the two detection positions P21 is the shortest set and is extracted as a condition set. Furthermore, in the condition set constituted by the first detection position P11 and the second detection position P21, the area 81A is larger than the area 83A, so the detection position P11 is determined as the designated position.

  Similarly, the first detection position P12 and the three second detection positions P21, P22, and P23 are configured by the first detection position P12 and the second detection position P21 among the three range restriction sets configured. Range limit set and the range limit set composed of the first detection position P12 and the second detection position P22 are long because the distance between the first detection position and the second detection position is less than or equal to the length TL. Furthermore, since each length restriction group includes the same first detection position P12, it is an overlapping group. Here, the distance L22 between the first detection position P12 and the second detection position P22 is shorter than the distance L21 between the first detection position P12 and the second detection position P21. The length limit set composed of the two detection positions P22 is the shortest set and is extracted as a condition set. Further, in the condition set constituted by the first detection position P12 and the second detection position P22, the area 81B is larger than the area 83B, so the detection position P12 is determined as the designated position.

  Therefore, three points of the detection position P11, the detection position P12, and the detection position P23 are determined as the designated positions.

<First Modification>
The mobile communication terminal 1 in the above embodiment extracts the shortest set as a condition set from a plurality of overlapping sets. However, between the first detection position and the second detection position in the plurality of overlapping sets. When there are a plurality of overlapping pairs with the smallest distance, or when the difference in distance between the first detection position and the second detection position is small, the detection position with the maximum or minimum Y coordinate among the plurality of overlapping sets is determined. An overlapping set included in the first detection position or the second detection position may be extracted as a condition set.

  FIG. 8 is a second diagram illustrating an example when a plurality of detection positions are detected on each of the first touch panel and the second touch panel. Referring to FIG. 8, regions 77A and 77B each indicate a region where the user touches first touch panel 17, second touch panel 18, and intermediate band 75 simultaneously with one finger. In this case, the first touch panel 17 detects the area 81A and the area 81B represented by oblique lines, the first detection position P11 and the area of the area 81A, which are the coordinates of the center of gravity of the area 81A, and the coordinates of the center of gravity of the area 81B. The first detection position P12 and the area of the region 81B are output to the CPU 21. Further, the second touch panel 18 detects the regions 83A and 83B represented by diagonal lines, and the second detection position P21, which is the coordinates of the center of gravity of the region 83A, the area of the region 83A, and the coordinates of the center of gravity of the region 83B. 2 The area of the detection position P22 and the area 83B is output to the CPU 21.

  The first detection positions P11 and P12 are located within the first range 71, and the second detection positions P21 and P22 are located within the second range 73. In this case, there are two range restriction sets each composed of the first detection position P11 and the two second detection positions P21 and P22, and the first detection position P12 and the two second detection positions P21 and P22. Two range restriction sets that are constructed are generated.

  On the other hand, in the two range restriction sets configured by the first detection position P11 and the two second detection positions P21 and P22, the distance between the first detection position and the second detection position is less than or equal to the length TL. Therefore, it is a length restriction group, and furthermore, each length restriction group includes the same first detection position P11, and thus is an overlapping group. Here, the distance L11 between the first detection position P11 and the second detection position P21 is the same as the distance L12 between the first detection position P11 and the second detection position P22. In this case, the Y coordinates of the second detection position P21 and the second detection position P22 are compared, the second detection position P21 having a small Y coordinate is selected, and the first detection position P11 and the second detection position P21 are configured. Are extracted as condition pairs. Furthermore, in the condition set constituted by the first detection position P11 and the second detection position P21, the area 81A is larger than the area 83A, so the detection position P11 is determined as the designated position.

  On the other hand, of the two range restriction groups constituted by the first detection position P12 and the two second detection positions P21 and P22, the range restriction constituted by the first detection position P12 and the second detection position P21. Since the distance between the first detection position and the second detection position is greater than the length TL, the pair is not a length restriction pair, but is a range restriction composed of the first detection position P12 and the second detection position P22. Since the distance between the first detection position and the second detection position is equal to or less than the length TL, the group is a length-limited group. Further, in the condition set constituted by the first detection position P12 and the second detection position P22, the area 81B is larger than the area 83B, so the detection position P12 is determined as the designated position.

  Therefore, two points of the detection position P11 and the detection position P12 are determined as the designated positions.

<Second Modification>
As a method for extracting the shortest set as a condition set from among a plurality of overlapping sets, when the first touch panel 17 and the second touch panel 18 output the shape of the detected area, the condition set based on the area shape is used. May be extracted.
FIG. 9 is a third diagram illustrating an example when a plurality of detection positions are detected on each of the first touch panel and the second touch panel. Referring to FIG. 9, area 77A indicates an area where the user touches first touch panel 17, second touch panel 18, and intermediate band 75 simultaneously with one finger, and area 77B indicates that the user touches another finger. The area | region which touches the 2nd touch panel 18 and the intermediate strip 75 simultaneously is shown. In this case, the first touch panel 17 detects a region 81A represented by oblique lines, and outputs the first detection position P11, which is the coordinates of the center of gravity of the region 81A, and the area of the region 81A to the CPU 21. Further, the second touch panel 18 detects the regions 83A and 83B represented by diagonal lines, and the second detection position P21, which is the coordinates of the center of gravity of the region 83A, the area of the region 83A, and the coordinates of the center of gravity of the region 83B. 2 The area of the detection position P22 and the area 83B is output to the CPU 21.

  The first detection position P11 is located in the first range 71, and the second detection positions P21 and P22 are located in the second range 73.

  In this case, two range restriction sets including the first detection position P11 and the two second detection positions P21 and P22 are generated. Since the two range restriction pairs configured by the first detection position P11 and each of the two second detection positions P21 and P22 have a length TL or less between the first detection position and the second detection position, they are long. Furthermore, since each length restriction group includes the same first detection position P11, it is an overlapping group. Here, the distance L11 between the first detection position P11 and the second detection position P21 is the same as the distance L12 between the first detection position P11 and the second detection position P22. In this case, the inclination of the straight line connecting the second detection position P21 and the midpoint of the contour that contacts the intermediate band 75 of the region 81A is connected to the midpoint of the contour that contacts the second detection position P21 and the intermediate band 75 of the region 83A. Comparison is made with the slope of the straight line and the slope of the straight line connecting the second detection position P22 and the midpoint of the contour contacting the intermediate band 75 of the region 83B. A length restriction set including the second detection position P21 having an inclination approximate to the inclination of a straight line connecting the second detection position P21 and the midpoint of the outline in contact with the intermediate band 75 of the region 81A is determined as a condition set. Furthermore, in the condition set constituted by the first detection position P11 and the second detection position P21, the area 81A is larger than the area 83A, so the detection position P11 is determined as the designated position. Therefore, the detection position P11 and the detection position P22 are determined as designated positions.

<Third Modification>
As a method for extracting the shortest pair as a condition pair from among a plurality of overlapping pairs, a locus is calculated from the past history of the detected position, and the locus of the first detection position detected by the first touch panel 17 and the second When the locus of the second detection position detected by the touch panel 18 approximates the inclination, the condition set is determined. As described above, in the mobile communication terminal 1 according to the present embodiment, the first LCD 15 and the second LCD 16 are intermediate. The first detection position is detected by the first touch panel 17 disposed so as to overlap the first LCD 15 and the second touch panel 18 disposed so as to be superimposed on the second LCD 16. A detection position is detected. Then, when the distance between the first detection position and the second detection position is within the predetermined length TL, a single instruction is made based on the first detection position and the second detection position. Determine the position. In addition, when there are a plurality of length restriction pairs in which the distance between the first detection position and the second detection position is within the predetermined length TL, the first of the plurality of length restriction pairs is used. A plurality of overlapping sets having the same one of the detection position and the second detection position are extracted, and a distance between the first detection position and the second detection position is extracted from the extracted plurality of overlapping sets. Select the shortest pair that is the smallest. Then, a single designated position is determined based on the first detection position and the second detection position included in the shortest set. Thus, even when the user instructs the display surface of the first LCD 15 and the display surface of the second LCD 16 simultaneously with one finger, it can be determined that the instruction is made with one finger. In addition, when the distance between the first detection position and the second detection position is longer than the predetermined length TL, a single designated position is not determined from the first detection position and the second detection position. Since each is in the designated position, it can be determined that the instruction is made with two fingers. Thereby, the precision which detects the position which the user instruct | indicated with the finger | toe can be improved.

  In the present embodiment, the example in which the width of the first range 71 and the second range 73 is set to 1.2 cm (= 2−0.8) in advance has been shown. Accordingly, the widths of the first range 71 and the second range 73 may be varied to reduce the number of overlapping sets.

  In the above-described embodiment, the mobile communication terminal 1 has been described. However, the invention can be understood as an input method for executing the processing shown in FIG. 5 and an input program for causing the CPU 21 to execute the input method. Needless to say.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
