  The main control unit 2j reads the image data with the data number 1 from the memory 2h through the memory control unit 2i, and then displays the image with the data number 1 on the display 2b through the display control unit 2g (S2). .

  When main controller 2j detects that an image transmission key (not shown) is pressed by the user (YES in S3), main control unit 2j issues a signal generation command for instructing transmission signal generation unit 2f to generate a data transmission request signal. Output.

  Upon receiving this signal generation command, the transmission signal generation unit 2f generates a data transmission request signal and outputs this signal to the infrared communication unit 2a.

  When receiving the data transmission request signal, the infrared communication unit 2a modulates the signal into an infrared signal and transmits the infrared signal to the display device 1 (S4).

  When the data transmission permission signal is received from the display device 1 (S5), the infrared communication unit 2a outputs this signal to the received signal analysis unit 2e. In the received signal analyzer 2e, processing for extracting and identifying portable terminal identification information from the data transmission permission signal is performed (see FIG. 11). Details of this processing will be described later.

  When the extracted mobile terminal identification information matches the mobile terminal identification information of the mobile phone 2, the received signal analysis unit 2e mainly uses the match information and the data transmission permission signal indicating that the mobile terminal identification information matches. Output to the controller 2j.

  When receiving the coincidence information and the data transmission permission signal, the main control unit 2j acquires the image data with the data number 1 from the memory 2h via the memory control unit 2i, and outputs this image data to the transmission signal generation unit 2f.

  The transmission signal generation unit 2f generates transmission image data by adding mobile terminal identification information to the image data, and outputs the image data to the infrared communication unit 2a.

  When receiving the image data for transmission, the infrared communication unit 2a modulates the image data for transmission into an infrared signal and transmits it to the display device 1 (S6).

  When this transmission is completed, the main control unit 2j causes the transmission signal generation unit 2f to generate a data transmission completion signal, and transmits this signal from the infrared communication unit 2a to the display device 1 (S7).

  When this transmission is completed, the main control unit 2j detects whether or not the image transmission key is kept pressed (S8). If it remains pressed (NO in S8), it waits until a data reception completion signal is received.

  When the data reception completion signal is received (S9), the infrared communication unit 2a outputs this signal to the reception signal analysis unit 2e. In the received signal analysis unit 2e, processing for extracting and identifying mobile terminal identification information from the data reception completion signal (see FIG. 11) is performed.

  On the other hand, when it is detected that the image transmission key has been released (YES in S8), main controller 2j outputs a signal generation command for instructing generation of an invalid request signal (stop signal) to transmission signal generator 2f. To do.

  Upon receiving this signal generation command, the transmission signal generation unit 2f generates an invalid request signal to which the mobile terminal identification information is added, and outputs this signal to the infrared communication unit 2a.

  When receiving the invalidation request signal, the infrared communication unit 2a modulates the signal into an infrared signal and transmits it to the display device 1 (S11).

  As described above, when the user can transmit the data transmission request signal to the intended infrared communication unit, the user can transmit the image data by continuously pressing the image transmission key. Otherwise, the user releases the image transmission key. The processing can be invalidated.

  Then, the main control unit 2j displays the image of data number 1 again on the display 2b via the display control unit 2g (returns to S2).

  If the image transmission key is not pressed (NO in S3) and it is detected that a transmission end key (not shown) is pressed (YES in S12), main controller 2j sends transmission signal generator 2f and A transmission end signal is transmitted to the display device 1 via the infrared communication unit 2a (S13), and a series of processing ends.

However, the above determination may be made at any time after the image transmission key is pressed until the data reception completion signal is received.

(4-2. Subroutine of processing in the mobile phone 2)
Next, a reception processing subroutine for extracting the mobile terminal identification information from the received signal and making a comparison determination with the registered mobile terminal identification information will be described with reference to FIG. FIG. 11 is a flowchart showing a processing subroutine in the mobile phone 2.

  This subroutine is a routine when the mobile phone 2 receives the data transmission permission signal and the data reception completion signal transmitted from the display device 1. In the following description, the data transmission permission signal and the data reception completion signal are simply referred to as reception signals.

  As shown in FIG. 11, first, when a reception signal is received by infrared communication unit 2a (YES in S21), infrared communication unit 2a outputs the reception signal to identification information extraction unit 2k.

  When receiving the received signal, the identification information extracting unit 2k extracts the mobile terminal identification information from the received signal and outputs the extracted information to the identification information comparing unit 21.

  Upon receiving the mobile terminal identification information, the identification information comparison unit 21 compares the mobile terminal identification information with the mobile terminal identification information of the mobile phone 2 (S22).

  When it is determined that the mobile terminal identification information matches, that is, when the received signal is addressed to the own device (YES in S22), the identification information comparison unit 2l determines that the match information, the mobile terminal identification information, The received signal is output to the received signal determining unit 2m.

  Upon receiving the match information and the received signal, the received signal determining unit 2m determines the information (contents) of the received signal (S23), and outputs the mobile terminal identification information to the transmission signal generating unit 2f. Is output to the main control unit 2j.

  On the other hand, when the mobile terminal identification information does not match (NO in S22), identification information comparison unit 21 waits until a new reception signal is received (returns to S21).

(5-1. Flow of processing in display device 1)
Next, a flow of processing performed in the display device 1 when transmitting a plurality of image data stored in the mobile phone 2 to the display device 1 will be described with reference to FIGS. FIG. 12 is a flowchart showing the flow of processing in the display device 1.

  As shown in FIG. 12, first, the main control unit 1j resets the memory 1h via the memory control unit 1i (S31).

  When the data transmission request signal transmitted from the mobile phone 2 is received (S32), the first infrared communication unit 1a or the second infrared communication unit 1b outputs the signal to the reception communication unit determination unit 1l.

  When receiving the data transmission request signal, the reception communication unit determination unit 11 determines whether or not the signal is received by both the first infrared communication unit 1a and the second infrared communication unit 1b (S33).

  If it is determined that the data transmission request signal has been received by both infrared communication units (YES in S33), reception communication unit determination unit 11 outputs unidentifiable information to main control unit 1j.

When the unidentifiable information is received, the main control unit 1j displays that the infrared communication unit cannot be identified on the display 1c via the display control unit 1g (S34), and waits until a new data transmission request signal is received (S32). Back to).

  On the other hand, if it is determined that the data transmission request signal is received by either first infrared communication unit 1a or second infrared communication unit 1b (NO in S33), reception communication unit determination unit 1l performs data transmission. It is determined whether or not the request signal is received by the first infrared communication unit 1a (S35).

  If it is determined that it is received by first infrared communication unit 1a (YES in S35), reception communication unit determination unit 1l outputs first specific information indicating the determination result to main control unit 1j.

  When the first specific information is received, the main control unit 1j generates a data transmission permission signal and outputs a signal generation command instructing transmission from the first infrared communication unit 1a to the transmission signal generation unit 1f.

  When this signal generation command is received, the transmission signal generation unit 1f generates a data transmission permission signal and outputs the signal to the first infrared communication unit 1a.

  Upon receiving the data transmission permission signal, the first infrared communication unit 1a modulates the signal into an infrared signal and transmits the infrared signal to the mobile phone 2 (S36a).

  When this transmission is finished, the main control unit 1j starts measuring time T using the timer 1k (S37a). Further, the main control unit 1j displays on the display 1c via the display control unit 1g that the first infrared communication unit 1a has received the data transmission request signal (S38a).

  FIG. 13 shows a schematic diagram of the display 1c displaying that the data transmission request signal has been received by the first infrared communication unit 1a. As shown in FIG. 13, the characters “data transfer in progress” may be displayed in the display area near the first infrared communication unit 1a (the left side), or the characters “region 1 data transfer in progress” may be displayed appropriately. You may display in a position. Further, the background screen may be changed or the screen may blink.

  The time T is a time (infrared communication unit confirmation time) for allowing the user to confirm whether or not the data transmission request signal has been transmitted to the intended infrared communication unit. If not as intended, the user can stop the process by sending an invalid request signal (S11, see FIG. 10). The time T may be set to about several seconds.

  As shown in FIG. 12, when the image data transmitted from the mobile phone 2 is received (S39a), the first infrared communication unit 1a or the second infrared communication unit 1b outputs the image data to the main control unit 1j.

  When the image data is received, the main control unit 1j stores the image data in a temporary storage memory (not shown) included in the main control unit 1j.

  Furthermore, when the data transmission completion signal transmitted from the mobile phone 2 is received (S40a), the first infrared communication unit 1a or the second infrared communication unit 1b outputs the signal to the main control unit 1j.

  Upon receiving the data transmission completion signal, the main control unit 1j determines whether or not the time T has elapsed (S41a).

  If it is determined that time T has not elapsed (NO in S41a), main controller 1j waits until time T elapses.

  If it is determined that time T has elapsed (YES in S41a), main controller 1j causes transmission signal generator 1f to generate a data reception completion signal and transmits it from first infrared communication unit 1a to mobile phone 2. (S43a).

  Further, the main control unit 1j overwrites and stores the received image data in the memory area A of the memory 1h via the memory control unit 1i (S44a).

  Thereafter, the main control unit 1j displays an image based on the image data in the first display area of the display 1c via the display control unit 1g (S45a).

  Then, when a transmission end signal is received from mobile phone 2 (YES in S47), main control unit 1j ends a series of processes.

  On the other hand, when the transmission end signal has not been received (NO in S47), main controller 1j waits until a new data transmission request signal is received (returns to S32).

  When an invalid request signal is received during the above process (YES in S42a), first infrared communication unit 1a or second infrared communication unit 1b outputs the signal to main control unit 1j.

  When the invalid request signal is received, the main control unit 1j displays on the display 1c that the image display is to be stopped via the display control unit 1g (S46a), and waits until a new data transmission request signal is received. (Return to S32).

  On the other hand, if it is determined that the data transmission request signal is not received by first infrared communication unit 1a (NO in S35), reception communication unit determination unit 1l uses the second specific information indicating the determination result as the main control unit. Output to 1j.

  When the second specific information is received, the main control unit 1j generates a data transmission permission signal and outputs a signal generation command instructing transmission from the second infrared communication unit 1b to the transmission signal generation unit 1f.

  When this signal generation command is received, the transmission signal generation unit 1f generates a data transmission permission signal and outputs the signal to the second infrared communication unit 1b.

  When receiving the data transmission permission signal, the second infrared communication unit 1b modulates the signal into an infrared signal and transmits the infrared signal to the mobile phone 2 (S36b).

  The subsequent processing flow is the same as described above, and is therefore omitted.

(5-2. Processing of mobile terminal identification information)
Note that the display device 1 extracts mobile terminal identification information from various received signals, thereby identifying which mobile phone 2 the signal is transmitted from. In addition, the display device 1 adds mobile terminal identification information of the destination mobile phone 2 to various signals to be transmitted. The flow of processing relating to the mobile terminal identification information will be described below.

  First, when the first infrared communication unit 1a or the second infrared communication unit 1b receives a signal, the signal is sent to the identification information extraction unit 1m via the reception communication unit determination unit 1l.

  The identification information extraction unit 1m extracts the mobile terminal identification information from the signal and outputs it to the transmission signal generation unit 1f.

  When receiving the mobile terminal identification information, the transmission signal generation unit 1f stores the information in a temporary storage memory (not shown) included in the transmission signal generation unit 1f. When the transmission signal generator 1f receives various signal generation commands from the main controller 1j, the transmission signal generator 1f adds the mobile terminal identification information to the generated signal. And this signal is output to the 1st infrared communication part 1a or the 2nd infrared communication part 1b.

  When transmitting a data transmission request signal to the display device 1, the mobile phone 2 transmits to either the first infrared communication unit 1a or the second infrared communication unit 1b. FIG. 14 shows a flow of processing when a data transmission request signal is transmitted to the first infrared communication unit 1a.

  As shown in FIG. 14, after a data transmission request signal is transmitted from the mobile phone 2 to the display device 1, image data is transmitted from the mobile phone 2 to the display device 1. At this time, when the data transmission request signal and the image data are received by the first infrared communication unit 1a, the display device 1 is transmitted to the first display region 5 which is a display region closer to the first infrared communication unit 1a. Display an image.

  Therefore, the user can select an image display area by selecting a direction in which the mobile phone 2 is directed. Thereby, the display apparatus 1 can be operated intuitively.

  In addition, the display of the received image data is stopped for a predetermined time (time T) after the data transmission permission signal is transmitted. By providing this time (infrared communication unit confirmation time), the user can confirm whether or not the data transmission request signal has been received by the intended infrared communication unit.

  Further, as shown in FIG. 15, the processing in the display device 1 can be interrupted by transmitting an invalid request signal from the mobile phone 2. With this configuration, for example, when the data transmission request signal is not received by the infrared communication unit intended by the user, the subsequent processing can be invalidated.

  In the above description, the cellular phone 2 transmits the invalid request signal using the image transmission key released during the index as an index. However, the invalidation request signal may be transmitted by pressing the key again, or the invalidation request signal may be transmitted by using another key as an index.

(7. Examples of changes)
When a data transmission request signal is received, it is received by either the first infrared communication unit 1a or the second infrared communication unit 1b, but when receiving image data, it may be received by both infrared communication units. . Further, signals other than the data transmission request signal may be transmitted and received by a communication method other than infrared communication, for example, a wireless method.

  A method of notifying the determination result of the reception communication unit determination unit 1l is not particularly limited. For example, it may be displayed as characters on the display 1c, or may be output as audio from the speaker 1d.

  Any of the plurality of operation keys 2c of the mobile phone 2 may be assigned to the image transmission mode setting key, the image transmission key, and the transmission end key. For example, a decision key or a side key that is easy to press may be assigned, or any key may be pressed to react.

  The number of display areas of the display 1c is not limited to two and may be any number. Further, in the above configuration, the first display area 5 and the second display area 6 are arranged on the left and right sides with the reference line 8 as a boundary, but the first display area 5 and the second display area 6 are the reference line 8. It may be arranged up and down with a line orthogonal to the boundary.

  Further, the first display area 5 and the second display area 6 may each include two display areas. In this case, there are a total of four display areas. When a data transmission request signal is received by the first infrared communication unit 1a, an image is displayed in the left display area with the reference line 8 as a boundary. When the data transmission request signal is received by the infrared communication unit 1b, an image may be displayed in the right display area with the reference line 8 as a boundary.

  When image data is sent from a plurality of mobile phones 2 to the display device 1, information indicating the mobile phone 2 (for example, the name of the owner of the mobile phone 2) is displayed together with the transmitted image. Also good. When notifying with LED etc., the color which shines may be changed according to an owner, and the pattern which shines may be changed.

  In the configuration described above, the mobile phone 2 transmits the image data after transmitting the data transmission request signal, but the image data may be transmitted without transmitting the data transmission request signal. In this case, the reception communication unit determination unit 11 determines which infrared communication unit has received the image data.

  Upon receiving this signal, the infrared communication unit 2a modulates the application activation request signal into an infrared signal and transmits it to the display device 10 (S52).

  When this transmission is completed, the main control unit 2j sets N = 1 to a counter (not shown) included in the main control unit 2j (S53).

  Next, the main control unit 2j reads the image data with the data number 1 from the memory 2h through the memory control unit 2i, and then displays the image with the data number 1 on the display 2b through the display control unit 2g. (S54).

  When the application activation permission signal transmitted from the display device 10 is received (S55), the main control unit 2j transmits the image data with the data number 1 from the infrared communication unit 2a (S56). At this time, the transmission signal generator 20a adds the mobile terminal identification information to the generated signal.

  The main control unit 2j waits until an operation request key (not shown) is pressed (S57).

  When it is detected that the operation request key has been pressed (YES in S57), main controller 2j outputs a signal generation command for instructing generation of an operation request signal to transmission signal generator 20a.

  Upon receiving this command, the transmission signal generation unit 20a generates an operation request signal, adds mobile terminal identification information to the generated signal, and outputs the signal to the infrared communication unit 2a.

  Upon receiving this signal, the infrared communication unit 2a modulates the operation request signal into an infrared signal and transmits it to the display device 10 (S58).

  When the control signal transmitted from the display device 10 is received (S59), the infrared communication unit 2a outputs the signal to the received signal determination unit 2m.

  When receiving the portable terminal control signal, the reception signal determining unit 2m determines whether the instruction of the signal is “forward” or “return” (not “forward”) (S60), and the determination result Is output to the main control unit 2j.

  If it is determined to be “advance” (YES in S60), main controller 2j adds 1 to the counter (N = 2) (S61).

  If determined to be “return” (NO in S60), main controller 2j subtracts 1 from the counter (N = 0) (S62).

  The main control unit 2j reads the image data with the data number 2 or 0 from the memory 2h through the memory control unit 2i, and then displays the image with the data number 2 or 0 on the display 2b through the display control unit 2g. Is displayed (return to S54).

  On the other hand, when it is detected in S57 that the operation end key (not shown) is pressed without pressing the operation request key (NO in S57, YES in S63), the main control unit 2j sends an operation end signal. Is transmitted (S64), and the series of processing ends.

  If there is no image data with data number 0, the image data with the largest number may be displayed, or an error message may be displayed.

(11. Flow of processing in display device 10)
Next, the flow of processing performed in the display device 10 when transmitting a plurality of image data stored in the mobile phone 20 to the display device 10 will be described with reference to FIG. FIG. 23 is a flowchart showing the flow of processing in the display device 10.

  As shown in FIG. 23, first, the main controller 1j resets the memory 1h via the memory controller 1i (S71).

  When the application activation request signal transmitted from the mobile phone 20 is received (S72), the first infrared communication unit 1a (or the second infrared communication unit 1b) outputs the signal to the identification information extraction unit 10g and the main control unit 1j. To do.

  When receiving the application activation request signal, the identification information extraction unit 10g extracts the mobile terminal identification information from the signal and outputs it to the transmission signal generation unit 10c and the identification information comparison unit 10h.

  When the mobile terminal identification information is received, the identification information comparison unit 10h stores the mobile terminal identification information in a memory (not shown) included in the mobile terminal identification information (S73). This process is for enabling only the mobile phone in which the mobile terminal identification information is registered to contact the display device 10 while the application is running. That is, this is to prevent a user other than the user who started the application from operating the display device 10.

  On the other hand, when receiving the application activation request signal, the main control unit 1j outputs a signal generation command for instructing generation of the application activation permission signal to the transmission signal generation unit 10c.

  Upon receiving this command, the transmission signal generation unit 10c generates an application activation permission signal, adds mobile terminal identification information to this signal, and then outputs the signal to the first infrared communication unit 1a (or the second infrared communication unit 1b). To do.

  When receiving the application activation permission signal, the first infrared communication unit 1a (or the second infrared communication unit 1b) modulates the signal to infrared and transmits the signal to the mobile phone 20 (S74).

  Then, when receiving the operation request signal from the mobile phone 2 (S75), the first infrared communication unit 1a or the second infrared communication unit 1b outputs the signal to the reception communication unit determination unit 10f.

  When receiving the operation request signal, the reception communication unit determination unit 10f determines whether the signal is received by both the first infrared communication unit 1a and the second infrared communication unit 1b (S76).

  If it is determined that the operation request signal has been received by both infrared communication units (YES in S76), reception communication unit determination unit 10f outputs unidentifiable information to main control unit 1j.

When the unidentifiable information is received, the main control unit 1j displays that the infrared communication unit cannot be identified on the display 1c via the display control unit 1g (S77), and waits until a data transmission request signal is received (return to S75). ).

  On the other hand, if it is determined that the operation request signal is received by either first infrared communication unit 1a or second infrared communication unit 1b (NO in S36), reception communication unit determination unit 10f receives a data transmission request. It is determined whether or not the signal is received by the first infrared communication unit 1a (S78).

  If it is determined that it is received by first infrared communication unit 1a (YES in S78), reception communication unit determination unit 10f outputs first specific information indicating the determination result to main control unit 1j.

  In addition, the reception communication unit determination unit 10f outputs an operation request signal to the identification information extraction unit 10g. The mobile terminal identification information extracted by the identification information extraction unit 10g is output to the identification information comparison unit 10h. The identification information comparison unit 10h determines whether or not the portable terminal identification information is registered. If the identification information comparison unit 10h determines that the portable terminal identification information is registered, the identification information comparison unit 10h determines the coincidence information. Output to the control unit 1j.

  When receiving the mismatch information, the main control unit 1j displays on the display 1c that the operation is impossible.

  When receiving the coincidence information and the first specific information, the main control unit 1j blinks the first LED 10a via the LED control unit 10e (S79a).

  Further, the main control unit 1j causes the transmission signal generation unit 10c to generate a control signal indicating “return” and transmits the control signal from the first infrared communication unit 1a (S80a).

  On the other hand, if it is determined that it has not been received by first infrared communication unit 1a (NO in S78), reception communication unit determination unit 10f outputs second specific information indicating the determination result to main control unit 1j.

  When receiving the coincidence information and the second specifying information, the main control unit 1j causes the second LED 10b to blink via the LED control unit 10e (S79b).

  Further, the main control unit 1j causes the transmission signal generation unit 10c to generate a control signal indicating “go” and transmits the control signal from the second infrared communication unit 1b (S80b).

  When receiving image data from the mobile phone 2 (S81), the main control unit 1j stores the image data in the memory 1h via the memory control unit 1i (S82).

  Then, the main control unit 1j displays an image based on the image data on the display 1c via the display control unit 1g (S83).

  Here, when it is detected that an operation end signal has been received (YES in S84), main controller 1j ends a series of image reception processes. Otherwise (NO in S84), main controller 1j waits until an operation request signal is received (return to S75).

(12. Effect)
Next, effects of the display device 10 and the mobile phone 20 will be described with reference to FIG. FIG. 24 is a diagram showing a sequence when image data is transmitted from the mobile phone 20 to the display device 10.

  As illustrated in FIG. 24, the mobile phone 20 transmits an application activation request signal to the display device 10, thereby asking the display device 10 for permission to activate an application for receiving image data. When the application is activated, the mobile phone 20 transmits an operation request signal.

  At this time, the type of control signal transmitted from the display device 10 to the mobile phone 20 is determined based on which one of the two infrared communication units included in the display device 10 has received the operation request signal. Is done.

  That is, the user can select the type of control signal by selecting the transmission destination of the operation request signal. Since this control signal controls the function of the mobile phone 20, the user can operate the mobile phone 20 indirectly by selecting the transmission destination of the operation request signal. Further, whether or not the mobile phone 20 can be operated as desired can be confirmed by looking at the display 1c of the display device 10.

  Therefore, unlike the conventional case, it is not necessary to move the line of sight greatly during the operation. In the conventional configuration, the mobile phone is directly operated by pressing the operation key of the mobile phone. In this case, the image to be transmitted is selected while viewing the image displayed on the display of the mobile phone while pressing the operation key. Further, in order to confirm whether or not the desired image data has been sent, the display of the display device is viewed. Therefore, it is necessary to move the line of sight greatly during the operation.

  In the display device 10 and the mobile phone 20, it is not necessary to move the line of sight greatly during operation, and an image can be selected by a simple operation of changing the direction of the mobile phone 20. Therefore, the image transmission operation can be performed easily and intuitively.

(13. Examples of changes)
When transmitting a control signal, you may transmit from both the 1st and 2nd infrared communication parts 1a * 1b. However, since the infrared communication unit that has received the operation request signal is likely to face the infrared communication unit 2a of the mobile phone 2 that has transmitted the operation request signal, control is performed from the infrared communication unit that has received the control signal. It is preferable to transmit a signal.

  In the above-described configuration, the control signal is transmitted and received by infrared communication. However, the mobile phone 20 and the display device 10 may each include a wireless communication unit, and may transmit and receive the control signal by wireless communication. Further, other communication means may be used.

  When the operation signal is received by the fourth infrared communication unit 11d after being received by the third infrared communication unit 11c, the cursor moves rightward and upward. Therefore, as shown in FIG. 30 (a), when the cursor is on channel 1, as shown in FIG. 30 (b), after the cursor moves to channel 2, as shown in FIG. Then, move to the channel 14.

  Note that when an upward movement instruction is received in a state where the cursor is on channels 1 to 4, channel 2 may remain selected because it cannot move upward.

  As described above, the display device 11 is configured to determine the moving direction of the cursor based on which infrared communication unit has received the operation signal.

(17. Flow of processing in mobile phone 21)
Next, a flow of processing performed in the mobile phone 21 when an operation signal is transmitted from the mobile phone 21 to the display device 11 will be described with reference to FIG. FIG. 31 is a flowchart showing the flow of processing in the mobile phone 21.

  As shown in FIG. 31, when it is detected that a display device operation key (not shown) is pressed by the user (YES in S91), main controller 2j generates an operation signal in transmission signal generator 21a. A signal generation command is issued to command

  As shown in FIG. 32, when the tuner 11g receives a broadcast of channels 1 to 16 (S101), the main control unit 1j sets the cursor position to the position of channel 1 (S102).

  Also, the main control unit 1j displays 16-channel thumbnails on the display 1c via the display control unit 1g (S103).

  When any of four infrared communication units 11a to 11d receives an operation signal from mobile phone 21 (YES in S104), the infrared communication unit outputs the operation signal to reception communication unit determination unit 11h.

  When receiving the operation signal, the reception communication unit determination unit 11h determines whether the signal is received by a plurality of infrared communication units (S105).

  If it is determined that the operation signal is received by a plurality of infrared communication units (YES in S105), reception communication unit determination unit 11h outputs unidentifiable information to main control unit 1j.

When the unidentifiable information is received, the main control unit 1j displays that the infrared communication unit cannot be identified on the display 1c via the display control unit 1g (S106), and waits until an operation signal is received (returns to S104).

  On the other hand, if it is determined that the operation signal is received by one of the infrared communication units (NO in S105), reception communication unit determination unit 11h receives the operation signal received by first infrared communication unit 11a. Is determined (S107a).

  If it is determined that the signal is received by first infrared communication unit 11a (YES in S107a), reception communication unit determination unit 11 outputs first specific information indicating the determination result to cursor movement direction determination unit 11f. .

If it is determined that the operation signal is received by the third infrared communication unit 11c, the cursor is moved rightward. If it is determined that it has been received by the fourth infrared communication unit 11d, the cursor is moved upward (S108b to 109b, S107c to S109c, S108d to S109d).

  If the operation end signal is received (YES in S110), main controller 1j ends the series of processes. Otherwise, the main control unit 1j waits until an operation signal is received (return to S104).

(19. Effect)
Next, effects of the display device 11 and the mobile phone 21 will be described with reference to FIG. FIG. 33 is a diagram showing a sequence when an operation signal is transmitted from the mobile phone 21 to the display device 11.

  As shown in FIG. 33, the moving direction of the cursor of the display device 11 is determined based on which infrared communication unit has received the operation signal transmitted from the mobile phone 21.

  Therefore, the user can instruct the moving direction of the cursor only by changing the direction in which the mobile phone 21 is directed.

  Further, the four infrared communication units 11a to 11d are arranged at positions corresponding to the moving direction of the cursor. Therefore, the user can move the cursor in a desired direction by transmitting an operation signal toward the infrared communication unit located in the direction in which the cursor is to be moved. Therefore, the user can move the cursor intuitively.

The reception communication unit determination unit 12e outputs the determination result to the identification information comparison unit 12g and the reception signal determination unit 12h, and outputs a voting signal to the identification information extraction unit 12f.

  The portable terminal identification information extraction unit 12f (hereinafter, identification information extraction unit 12f) extracts portable terminal identification information from the vote signal and outputs it to the identification information comparison unit 12g.

  The portable terminal identification information comparison unit 12g (hereinafter, identification information comparison unit 12g) compares the extracted portable terminal identification information with the registered portable terminal identification information based on the determination result of the reception communication unit determination unit 12e. , It is determined whether the vote is valid or invalid. The registered mobile terminal identification information will be described later. The identification information comparison unit 12g outputs valid information or invalid information to the reception signal determination unit 12h.

  When the reception signal determination unit 12h receives valid information from the identification information comparison unit 12g, the reception signal determination unit 12h refers to a temporary storage memory (not shown) included in the reception signal determination unit 12h so that the received voting signal transmits the voting signal. It is determined whether or not it is received from the telephone 2 for the first time. When the voting signal is received for the first time, the reception signal determination unit 12h outputs the determination result of the reception communication unit determination unit 12e to the voting signal aggregation unit 12b.

  The voting signal counting unit 12b counts how many times the voting signal is received for each infrared communication unit based on the determination result output from the reception signal determining unit 12h.

  Upon receipt of the mobile terminal identification information and the determination result, the identification information comparison unit 12g refers to the function correspondence table 7, and the mobile phone that has transmitted the vote signal determines whether the infrared communication unit has an access right. (S124).

  If it is determined that there is no access right (NO in S124), identification information comparison unit 12g outputs voting invalid information to main control unit 1j.

  When the vote invalid information is received, the main controller 1j displays that the vote is invalid on the display 1c via the display controller 1g (S123), and waits until a new vote signal is received (return to S121). .

  On the other hand, if it is determined that there is an access right (YES in S124), identification information comparison unit 12g outputs voting valid information and portable terminal identification information to reception signal determination unit 12h.

  When receiving the voting valid information and the mobile terminal identification information, the reception signal determination unit 12h determines whether or not the determination result indicates the fourth infrared communication unit 11d (S125).

  If it is determined that the determination result does not indicate the fourth infrared communication unit 11d (NO in S125), the reception signal determination unit 12h stores the mobile terminal identification information in a temporary storage memory (not shown) included in itself. (S126).

  If portable terminal identification information is already stored (YES in S126), reception signal determination unit 12h outputs voting invalid information to main control unit 1j. Upon receiving the vote invalid information, the main control unit 1j displays that the vote is invalid on the display 1c via the display control unit 1g (S127), and waits until a new vote signal is received (return to S121). .

  On the other hand, when the mobile terminal identification information is not stored (NO in S126), the reception signal determination unit 12h stores the mobile terminal identification information in a temporary storage memory (not shown) provided therein (S128). .

  Then, the reception signal determination unit 12h outputs the determination result of the reception communication unit determination unit 12e to the voting signal totaling unit 12b.

  Upon receiving the determination result, the voting signal counting unit 12b adds 1 to the counter of the infrared communication unit indicated by the determination result (S129). The infrared communication unit waits until a new vote signal is received (return to S121).

  On the other hand, if it is determined that the determination result is fourth infrared communication unit 11d (YES in S125), reception signal determination unit 12h outputs a totaling command to vote signal totaling unit 12b.

  When receiving the counting command, the voting signal counting unit 12b checks the counter of each infrared communication unit and creates a counting result table (not shown) indicating the counting result (S130). The voting signal totaling unit 12b outputs this totaling result table to the transmission signal generating unit 12c and the main control unit 1j.

  When receiving the total result table, the main control unit 1j displays the voting result based on the total result table on the display 1c via the display control unit 1g (S131).

  When receiving the voting result table, the transmission signal generating unit 12c generates a voting result signal based on the voting result table and outputs it to the wireless communication unit 12d.

  Upon receiving the vote result signal, the wireless communication unit 12d modulates the signal into a wireless signal and transmits it to each mobile phone 22 (S132), and the series of processing ends.

(25. Effect)
Next, effects of the display device 12 and the mobile phone 22 will be described with reference to FIG. FIG. 40 is a diagram illustrating a sequence for transmitting a voting signal from the mobile phone 22 to the display device 12.

  As shown in FIG. 40, voting signals are transmitted from the four mobile phones 22 (mobile phones A to D) to the display device 12. At this time, a voting destination is determined depending on which infrared communication unit the four infrared communication units transmit to.

  Therefore, the user (voting person) can select a vote destination by a simple operation of selecting a direction in which the mobile phone 22 is directed.

  The fourth infrared communication unit 11d receives a signal for ending voting. By transmitting a voting signal to the fourth infrared communication unit 11d, counting of the number of votes is started and the counting result is displayed. Therefore, the voting end operation can be performed only by selecting the direction in which the mobile phone 22 is directed.

  In addition, the mobile terminal identification information of the mobile phone A is registered in the function correspondence table 7, and when the voting signal from the mobile phone A is received by the first infrared communication unit 11a, the voting is invalidated.

  With this configuration, when Mr. A who owns the mobile phone A is one of the candidates, and the transmission of the voting signal to the first infrared communication unit 11a means voting for Mr. A, Mr. A can prevent himself from voting.

  In addition, by transmitting a totaling result signal representing the voting result by wireless communication instead of infrared communication, it can be simultaneously transmitted to a plurality of mobile phones 22. Further, when transmitting the totaling result signal, each mobile phone 22 may not be oriented in the direction of the display device 12. Therefore, it is preferable to transmit the totaling result signal by wireless communication in order to reliably transmit the totaling result signal.

(26. Examples of changes)
In the above-described configuration, counting of the number of votes has been started by transmitting a vote signal to the fourth infrared communication unit 11d. However, a separate operation key is provided to end the vote, and the fourth infrared communication unit 11d. May be used for voting for the fourth candidate.

  It may also be set so that candidates can vote for themselves. That is, the identification information comparison unit 12g may or may not determine whether the received voting signal is valid or invalid in the infrared communication unit that has received the voting signal.

  Moreover, you may make it the structure which invalidates the overlapping signal from the same mobile telephone based on the output signal of the identification information extraction part 12f.

  In the above configuration, the reception signal determination unit 12h is provided as the identification information comparison unit. However, the identification information comparison unit 12g may have a function as the identification information comparison unit of the reception signal determination unit 12h.

[Embodiment 5]
The following will describe another embodiment of the present invention with reference to FIGS. In addition, the same code | symbol is attached | subjected to the member similar to embodiment mentioned above, and the description is abbreviate | omitted. Hereinafter, the display device 14 will be described as an example of the electronic device. The mobile phone 2 will be described as an example of a mobile terminal that controls the display device 14.

(27. Appearance of display device 14)
FIG. 41 is a schematic view showing the appearance of the display device 14. As shown in FIG. 41, the display device 14 includes first and second infrared communication units 14a and 14b (reception unit, transmission unit) and a dual-view liquid crystal 14c (multi-view display unit).

  FIG. 42 is a schematic diagram showing the visible range of the dual-view liquid crystal 14c. As shown in FIG. 42, the dual view liquid crystal 14c is a display unit that displays different images depending on the viewing direction. Specifically, the video A can be seen from the left direction toward the display device 14, and the video B can be seen from the right direction toward the display device 14. In other words, the range of the direction in which the video A can be viewed (visible range) is different from the range of the direction in which the video B can be viewed. The contents of these images A and B are controlled independently of each other.

  The dual view liquid crystal 14c only needs to display a plurality of different images depending on the viewing direction, and the configuration is not particularly limited.

  The first and second infrared communication units 14 a and 14 b receive signals transmitted from the mobile phone 2 and transmit various signals, and are disposed on the front surface of the display device 14. The arrangement of the first and second infrared communication units 14a and 14b is not particularly limited, and the interval between the first infrared communication unit 14a and the second infrared communication unit 14b is not particularly limited.

  FIG. 43 shows the receivable ranges of the first and second infrared communication units 14a and 14b. As shown in FIG. 43, the range of signal directions that can be received by the first and second infrared communication units 14a and 14b are different from each other. Specifically, the first infrared communication unit 14a can receive a signal transmitted obliquely from the left front toward the display device 14, while the second infrared communication unit 14b is directed to the display device 14. Thus, a signal transmitted from diagonally forward right can be received. Therefore, it is possible to distinguish and receive signals transmitted from different directions without leaving an interval between the first infrared communication unit 14a and the second infrared communication unit 14b.

  In order to make the receiving ranges of the first and second infrared communication units 14a and 14b as described above, the first and second infrared communication units 14a and 14b are attached to the display device 14 as shown in FIG. What is necessary is just to adjust an attachment angle.

  As the first and second infrared communication units 14a and 14b, for example, those having the structure shown in FIG. 44 can be used. FIG. 44 is a schematic diagram showing the structure of the first infrared communication unit 14a. As shown in FIG. 44, the first infrared communication unit 14a includes a light receiving unit 13a (receiving unit) and a light emitting unit 13b (transmitting unit). The light receiving angle of the signal to the light receiving unit 13a and the radiation angle of the signal from the light emitting unit 13b are limited.

  The structure of the infrared communication unit is not limited to that described above, and any structure may be used as long as the range of angles at which signals from the mobile phone 2 can be received is limited.

(28. Configuration and effect of display device 14)
FIG. 45 is a schematic diagram illustrating an internal configuration of the display device 14. As shown in FIG. 45, the internal configuration of the display device 14 is substantially the same as the internal configuration of the display device 1. The processing flow in the display device 1 is substantially the same as the processing flow in the display device 1. The difference between the display device 14 and the display device 1 is that in the display device 14, when a signal from the mobile phone 2 is received by the first infrared communication unit 14 a, display processing relating to the video A is performed, and the second When a signal is received by the infrared communication unit 14b, a display process related to the video B is performed.

  42 and 43, the receivable range of the first infrared communication unit 14a is included in the visible range of the image A, and the receivable range of the second infrared communication unit 14b is the visible range of the image B. Included in the range.

  Therefore, when a signal is transmitted from a position where the video A can be seen, the signal is highly likely to be received by the first infrared communication unit 14a. When the first infrared communication unit 14a receives the signal, display processing relating to the video A is performed. The display process related to the video A may be, for example, changing the content of the video A, or changing the display format of the video A (for example, playback speed, split display format).

  On the other hand, when a signal is transmitted from a position where the video B can be viewed, the signal is highly likely to be received by the second infrared communication unit 14b. When the second infrared communication unit 14b receives the signal, a display process for the video B is performed.

  As described above, the receivable ranges of the first and second infrared communication units 14a and 14b and the visible range where the image displayed on the dual view liquid crystal 14c can be seen overlap at least partly, and the signal is received. Display processing relating to a video having a visible range that overlaps the receivable range of the infrared communication unit is performed.

  Therefore, the display content of the video can be changed based on a signal transmitted from a position where a video can be viewed.

(29. Examples of changes)
In the above configuration, the dual-view liquid crystal 14c is used as the multi-view display unit, but a display unit that can view different images from three directions may be used as the multi-view display unit.

As shown in FIG. 47, the receivable range of the first infrared communication unit 15a and the receivable range of the third infrared communication unit 15c extend substantially in parallel, and the receivable range of the second infrared communication unit 15b and the fourth receivable range. It extends substantially parallel to the receivable range of the infrared communication unit 15d.

  And when a signal is received by the 1st infrared communication part 15a or the 3rd infrared communication part 15c, the process regarding the display of the image | video A is performed, and a signal is received by the 2nd infrared communication part 15b or the 4th infrared communication part 15d. Is received, processing relating to display of video B is performed.

  Therefore, when the display content of the video A is changed by transmitting a signal from the position where the video A can be seen, the signal may be transmitted to the first infrared communication unit 15a or transmitted to the third infrared communication unit 15c. May be. Therefore, the signal from the mobile phone 2 can be received more reliably than when there are two infrared communication units.
