  Next, the operation will be described.

  FIG. 4 is a diagram for explaining the operation of the mobile phone system according to the first embodiment. The mobile phone is remotely operated by a TV remote control device, and image data stored in the mobile phone is displayed on the TV. The flowchart of operation | movement is shown.

  First, when the user operates the power button of the operation unit 25 of the mobile phone 20, the control unit 26 turns on the power (not shown) of the mobile phone (step S1). After that, when the low-speed infrared communication unit 28 receives the low-speed infrared signal LIr output from the television remote control device 30, the control unit 26 compares the remote control code included in the received low-speed infrared signal LIr. It is determined whether the code for use is stored in the memory unit 24 (step S2). When the comparison code is not stored in the memory unit 24, the control unit 26 causes the memory unit 24 to store the remote control code transmitted from the remote control device as a comparison code (step S3), and then the control unit 26 enters an input waiting state (step S4). This comparison code is a code for determining whether or not to perform high-speed infrared communication control when a predetermined remote control code for low-speed infrared communication is received, and needs to be stored in the memory unit 24 in advance. There is. However, here, when the comparison code is not stored in the memory unit 24, the remote control code transmitted first is stored as the comparison code in the memory unit 24, which affects the display on the television. It is desirable to transmit a remote control code that is not given, for example, a remote control code corresponding to a volume adjustment button.

  On the other hand, when the comparison code is stored in the memory unit 24, the control unit 26 waits for input (step S4), and then the low-speed infrared communication unit 28 receives the low-speed infrared signal LIr from the remote control device 30. When the control unit 26 receives the remote control code included in the received low-speed infrared signal LIr (step S5), the control unit 26 stores the received remote control code in the memory unit 24. It is determined whether the code matches the comparison code (step S6).

  When the received remote control code matches the comparison code, the control unit 26 and the memory unit 24 and the high-speed infrared communication so that the high-speed infrared communication corresponding to the remote control code received by the low-speed infrared communication unit 28 is performed. The infrared communication unit 27 is controlled (step S7). That is, the control unit 26 reads the image data stored in the memory unit 24 of the mobile phone 20, transfers the read image data to the high-speed infrared communication unit 27, and the control unit 26 further includes the high-speed infrared communication unit. 27 controls the high-speed infrared communication unit 27 to transfer the image data to the television 10 by the high-speed infrared signal HIr.

  Then, in the television 10, the high-speed infrared communication unit 16a receives the high-speed infrared signal HIr from the mobile phone 20, outputs the image information included in the high-speed infrared signal HIr to the video processing unit 14a, and the high-speed infrared signal. The communication unit 16a notifies the control unit 10b of the television 10 that the high-speed infrared signal HIr is being received. Then, the control unit 10b controls the image processing unit 14b to display the image data from the high-speed infrared communication unit 16a on the display unit 15a. As a result, the image data stored in the mobile phone 20 is displayed on the display unit 15a.

  Then, the control unit 26 determines whether or not the transmission of the image data by the high-speed infrared communication in the infrared communication unit 27 is finished (step S8), and if the transmission of the image data is not finished, the high-speed infrared ray is transmitted. Transmission of image data by communication is continued (step S7). On the other hand, as a result of the determination in step S8, if the transmission of the image data has been completed, whether or not to terminate the infrared communication of the image data based on a user input such as operating the power-off button. Is determined (step S9). As a result of the determination in step S9, when it is determined that communication should be terminated by user input, the power is turned off (step S10).

  In the mobile phone system 100 according to the first embodiment having such a configuration, the mobile phone 20 normally has a high-speed infrared communication function compliant with standards such as IrDA and IrSimple. Image data and the like can be transferred wirelessly from the mobile phone 20 at high speed, and the image data stored in the mobile phone can be enlarged and displayed on the display screen of the television.

  Further, in data transfer by high-speed infrared communication, there is a restriction that the transmission side device and the reception side device must be brought close to each other. However, the mobile phone 20 receives the infrared communication remote control code from the remote control device 30 for controlling the television 10. Therefore, even if the mobile phone 20 is placed near the TV 10, the mobile phone 20 can be operated by remote control from a remote location. The mobile phone 20 can be controlled by the device 30, and the image data stored in the mobile phone 20 can be transferred to the television 10 by high-speed infrared communication and displayed on the display device. In this way, by operating the remote controller 30, the user can transfer the stored image of the mobile phone to the television at a high speed from a remote location. As a result, the display device of the television can It is possible to enlarge and view an image obtained by photographing with a built-in camera or the like.

  In addition, since infrared rays have directivity, as shown in FIG. 1, the transmission surface of the high-speed infrared signal of the mobile phone 20 faces the side where the TV is positioned with respect to the mobile phone body, and the remote control device 30 By arranging the mobile phone 20 so that the receiving surface of the infrared signal faces away from the television with respect to the mobile phone body, the communication operation can be performed most efficiently.

  As described above, in the first embodiment, in the infrared communication system including the mobile phone with the infrared communication function, the infrared communication function for performing image transmission or the like of the multifunctional mobile phone is used, and is built in the mobile phone. When displaying the image data on the television, the user can remotely control the mobile phone from a remote location with the remote control device of the television and display the image data stored in the mobile phone on the television.

  Further, as shown in FIG. 1, the mobile phone 20 is arranged such that the end surface for performing high-speed infrared communication (transmission) faces the TV side, and the low-speed infrared communication (reception) faces the opposite side of the TV side. Therefore, since infrared has directivity, high-speed infrared communication between the mobile phone 20 and the television 10 and further low-speed infrared communication between the mobile phone 20 and the remote control device 30 can be performed efficiently. .

  In the above embodiment, a system is shown in which an image obtained by photographing with a built-in camera or the like of the mobile phone 20 is transferred to the television 10 and displayed on the display device in an enlarged manner. In addition to the captured image, for example, a mobile phone 20 that is multifunctional displays a game screen displayed by the game function on a television display device, and the remote control device 30 remotely operates the mobile phone 20 to It is also possible to enjoy a game mounted on the telephone 20.
