Description

  The present invention relates to an information processing terminal and an information processing method for acquiring a destination address and wirelessly transmitting information to the destination.

  As a method for performing communication between a plurality of devices in a limited area, a method of forming a wireless communication network based on Bluetooth (registered trademark) between a plurality of devices is considered.

  In Bluetooth, 'Bluetooth Device Address' is assigned to each device, and as shown in FIG. 8, the device 1 is a push client (transmission side device) between the devices 1 and 3 each having the Bluetooth module 2 and 4, respectively. In forming a wireless communication network in which the device 3 is a push server (receiving device), the device 1 needs to acquire “Bluetooth Device Address” of the device 3.

  'Bluetooth Device Address' is information that uniquely identifies a Bluetooth device, and is expressed in 12 hexadecimal characters such as '00: 0C: 3E: 3A: 4B: 69' or '000C3E3A4B69'. This is an address of 48 bits (6 bytes) in total. Hereinafter, 'Bluetooth Device Address' is referred to as a device address.

  In addition to the device address, the Bluetooth device can be attached with 'Bluetooth Device Name' or 'Class of Device'. 'Bluetooth Device Name' indicates the name of the device such as 'VAIO (registered trademark) C1', and 'Class of Device' indicates the category name of the device such as 'PC' or 'PDA'. Indicates the name of the service provided by the device. Hereinafter, 'Bluetooth Device Name' is referred to as a device name, and 'Class of Device' is referred to as a device category.

  When the device 1 acquires the device address of the device 3, the device 1 can connect to the device 3 and transmit information to the device 3 in the connection phase.

  As a method for acquiring the device address of the device 3 in the device 1, a method as shown in FIG. 9 is conventionally used.

  In the device address acquisition processing routine of FIG. 9, the CPU of the device 1 first searches for a device in step 91. This device search is executed by requesting the device 1 to transmit a device address from the device 1 to a peripheral device, and in response to this, the peripheral device transmits its own device address.

  Next, the CPU of the device 1 acquires the device address of the peripheral device in step 92, further requests in step 93 to transmit the device name to the device that transmitted the device address, and further in step 94, Get the device name of the device that sent the device address.

  Next, in step 95, the CPU of the device 1 displays the acquired device address and device name on the display of the device 1. When the device address of the target device 3 is acquired, the user selects it and performs an operation to end the search. When the device address of the target device 3 is not acquired, the user performs an operation to continue the search. .

  Next, in step 96, the CPU of the device 1 determines whether or not the device address of the target device has been acquired from the user's operation, and if not, returns from step 96 to step 91 to return to the device. When the search is continued and acquired, the process proceeds from step 96 to step 97 to determine the device address of the target device and register it in the device 1.

  Thus, by acquiring the device address of the device 3 in the device 1, a wireless communication network is formed between the devices 1 and 3, and thereafter, the device 1 is connected to the device 3 in the connection phase and connected to the device 3. Information can be sent.

  However, in the above-described conventional method, it takes about 10 to 30 seconds to search for a device once, and when there are some Bluetooth devices in addition to the target device 3 around the device 1, Device 3 cannot be found and the device address cannot be obtained, or even if the device address can be obtained, the device name may not be obtained. In this case, the device search must be repeated many times. Therefore, it takes a long time to acquire the device address and device name of the target device 3, and the user has to be instructed to instruct the device 1 every time it searches.

  When the device 1 has an alphanumeric string input function, the device address of the device 3 can be directly input to the device 1, but when the device 1 does not have an alphanumeric string input function, the device 1 The device address of the device 3 cannot be directly input to 1. Even when the device 1 has an input function of an alphanumeric string, it is troublesome for the user to input the alphanumeric string directly into the device 1, and an input mistake is likely to occur.

Accordingly, the present invention is to obtain the address of the device of the destination, when transmitting information to the device wirelessly transmitting the information to reliably retrieve the address of the destination device in a short time It is made to be able to.

In this invention,
One-dimensional or two-dimensional information including name information of at least one of the name of the destination device, the name of the category, or the name of the service provided by the destination device in addition to the address of the destination device When a barcode is displayed on the transmission destination device, an imaging unit for imaging the displayed barcode and outputting it as image information ;
From the image information output by the imaging unit, a read processing unit that acquires the address of the destination device and the name information ;
Storage means for registering the address of the destination device and the name information acquired by the read processing unit;
Display means for displaying the address of the destination device registered in the storage means and the name information ;
A designation means for designating an address of the destination device of interest from the address of the destination device displayed on the display means and the name information ;
The information processing terminal includes a wireless transmission unit that wirelessly transmits information to a destination device specified by an address specified by the specifying means.

  In the information processing terminal according to the present invention configured as described above, only the barcode indicating the transmission destination address is photographed by the imaging unit included in the information processing terminal or the camera connected to the information processing terminal. Thus, the target destination address can be acquired, and the target destination address can be reliably acquired in a short time.

As described above, according to the present invention, the intended destination address is captured by the camera, registered in the storage means, and displayed on the display means. The address of the destination can be designated, and the address of the target destination can be acquired reliably in a short time.

  FIG. 1 shows an embodiment of a wireless communication system according to the present invention. A wireless communication system is configured by a digital still camera 10 as a Bluetooth push client and a mobile phone terminal 30 as a Bluetooth push server. In this case, the digital still camera 10 acquires the device address of the mobile phone terminal 30 to form a Bluetooth wireless communication network between the digital still camera 10 and the mobile phone terminal 30.

  The digital still camera 10 includes a lens 11 and the like on the front side, a CCD (Charge Coupled Device) on the inner side of the lens 11, a mode switch 13 and a shutter switch 14 on the top side, and the back side. A liquid crystal monitor 15, a battery and memory card storage chamber 16, a cross key 17a, a direct button 17b, a jog dial 17c, and the like, and a Bluetooth function as a push client are mounted.

  The cellular phone terminal 30 includes an operation input unit 31 including various operation keys and character input keys, a liquid crystal display 32 as a display unit, and the like, and is equipped with a Bluetooth function as a push server.

  FIG. 2 shows a functional block configuration of the digital still camera 10. Hereinafter, the digital still camera 10 is referred to as a camera 10.

  When the shutter switch 14 shown in FIG. 1 is pressed in the normal imaging mode or the device address acquisition mode described later, the CCD 12 is irradiated with light through the lens 11 and an image is taken. The image is output as image data by the read processing unit 21 and sent to the system bus 22.

  The system bus 22 includes a CPU 23, a program including a device address acquisition processing routine to be executed by the CPU 23, a ROM 24 in which fixed information such as a device address of the camera 10 is written, and a DRAM 25 that functions as a work area of the CPU 23. 1 is connected to the flash memory 26 for image file recording, the liquid crystal monitor 15 shown in FIG. 1, the mode switch 13 shown in FIG. 1, the shutter switch 14, the cross key 17a, the direct button 17b and the jog dial 17c. Is done. Furthermore, a Bluetooth module 29 is connected to the system bus 22 via a USB (Universal Serial Bus) interface 28.

  The flash memory 26 is configured as a memory card 27 and is installed in the storage chamber 16 shown in FIG.

  The image data output from the read processing unit 21 to the system bus 22 in the normal imaging mode is JPEG (Joint Photographic Experts Group) compressed by the CPU 23 and written in the flash memory 26 as an image file of a predetermined format.

  Image data output from the read processing unit 21 to the system bus 22 in the device address acquisition mode described later is written into the DRAM 25 by the CPU 23 and then processed as described later.

  Further, as will be described later, image data obtained by the camera 10 is converted into an object push profile for Bluetooth communication from the Bluetooth module 29 via the USB interface 28 by an object push operation on the camera 10. It is transmitted to the mobile phone terminal 30 in FIG.

  In the mobile phone terminal 30, the barcode 35 is displayed on the liquid crystal display 32 as an image indicating the device address of the mobile phone terminal 30 in the standby mode or by performing an operation of calling the device address with the operation input unit 31. The

  Specifically, the bar code 35 indicates that the error correction code is added to the device address of the mobile phone terminal 30, or the error correction code is added to the device address and the device name or the device category of the mobile phone terminal 30, respectively. Let's show what was added.

  When the user causes the camera 10 to acquire the device address of the mobile phone terminal 30 and forms a Bluetooth wireless communication network between the camera 10 and the mobile phone terminal 30, the liquid crystal display of the mobile phone terminal 30 is thus used. A bar code 35 is displayed on 32, and the camera 10 is switched to the device address acquisition mode.

  Thereby, the camera 10 acquires the device address of the mobile phone terminal 30 by the device address acquisition processing routine as shown in the examples of FIGS.

  In the device address acquisition processing routine 40 of the example of FIG. 3, in the device address acquisition mode, the CPU 23 of the camera 10 first enters the device address acquisition mode on the liquid crystal monitor 15 in step 41. "Please push the shutter toward", and so forth, indicating that the barcode 35 should be taken.

  In response to this, in step 42, the user points the camera 10 toward the portion where the barcode 35 on the liquid crystal display 32 of the mobile phone terminal 30 is displayed, and presses the shutter switch 14. Steps 42, 52 and 71 to 73 in FIGS. 3, 4 and 6 show operations performed by the user.

  Next, in step 43, the CPU 23 reads out image information from the CCD 12 by the reading processing unit 21, and further executes device address recognition processing in step 44. Specifically, in this example, a barcode is recognized from the image information, and the recognized barcode is decoded to obtain a device address.

  Next, in step 45, the CPU 23 determines whether or not the device address can be recognized, and when the total 48-bit address expressed in 12 hexadecimal characters as described above cannot be recognized, Proceeding from step 45 to step 46, a message indicating that the image should be captured again is displayed on the liquid crystal monitor 15, such as “Cannot be recognized.

  Accordingly, the user again presses the shutter switch 14 to photograph the barcode 35 in step 42, and the CPU 23 reads the image information from the CCD 12 in step 43, and executes device address recognition processing in step 44. .

  When it is determined in step 45 that the device address has been recognized, the CPU 23 proceeds to step 47 and recognizes the device address of the target device on the liquid crystal monitor 15 such as “The target device has been recognized”. The fact that it has been completed is displayed, and the process proceeds to step 48 where the recognized device address is registered in the DRAM 25.

  In the device address acquisition processing routine 50 of the example of FIG. 4, in the device address acquisition mode, the CPU 23 of the camera 10 first enters “device address acquisition mode on the LCD monitor 15 in step 51. "Please keep pressing the shutter toward", for example, to indicate that the shutter switch 14 should be kept pressed.

  In response to this, in step 52, the user keeps pressing the shutter switch 14 with the camera 10 directed toward the portion on the liquid crystal display 32 of the mobile phone terminal 30 where the barcode 35 is displayed.

  Next, in step 53, the CPU 23 reads out image information from the CCD 12, executes a device address recognition process in step 54, and further determines in step 55 whether or not the device address has been recognized.

  If the device address cannot be recognized, the process returns from step 55 to step 53, and the reading of the image information in step 53 and the device address recognition process in step 54 are repeated.

  When it is determined in step 55 that the device address has been recognized, the CPU 23 proceeds to step 57 and recognizes the device address of the target device on the liquid crystal monitor 15 such as “The target device has been recognized”. The fact that it has been completed is displayed, and the process proceeds to step 58 where the recognized device address is registered in the DRAM 25. When it is displayed in step 57 that the device address has been recognized, the user can release the shutter switch 14.

  In the device address acquisition processing routine 60 of the example of FIG. 5, in the device address acquisition mode, the CPU 23 of the camera 10 first enters the device address acquisition mode on the liquid crystal monitor 15 in step 61. “Please point” or the like to indicate that the camera 10 should be directed to the barcode 35.

  In response to this, the user points the camera 10 toward the portion on the liquid crystal display 32 of the mobile phone terminal 30 where the barcode 35 is displayed.

  Next, in step 62, the CPU 23 opens the shutter to photograph the bar code 35. Next, in step 63, the CPU 23 reads out image information from the CCD 12, and in step 64, executes device address recognition processing. In step 65, it is determined whether or not the device address has been recognized.

  If the device address cannot be recognized, the process returns from step 65 to step 62, and the photographing at step 62, the reading of image information at step 63, and the device address recognition process at step 64 are repeated.

  When it is determined in step 65 that the device address has been recognized, the CPU 23 proceeds to step 67 and recognizes the device address of the target device on the liquid crystal monitor 15 such as “The target device has been recognized”. The fact that it has been completed is displayed, and the process proceeds to step 68 where the recognized device address is registered in the DRAM 25. When it is displayed in step 67 that the device address has been recognized, the user can change the orientation of the camera 10.

  According to the above-described method, the barcode 35 is displayed on the liquid crystal display 32 of the mobile phone terminal 30, the camera 10 is switched to the device address acquisition mode, and the camera 10 only captures the barcode 35. The device address of the mobile phone terminal 30 can be acquired, and a Bluetooth wireless communication network can be formed between the camera 10 and the mobile phone terminal 30.

  When the device address of the mobile phone terminal 30 is acquired in the camera 10 as described above and a Bluetooth wireless communication network is formed between the camera 10 and the mobile phone terminal 30, the camera 10 is connected as shown in FIG. Depending on the phase, it is possible to connect to the mobile phone terminal 30 and transmit information to the mobile phone terminal 30.

  That is, in the connection phase 70, the user first sets the mobile phone terminal 30 to the push server mode in step 71, and then selects the mobile phone terminal 30 as the push server on the camera 10 side in step 72. Connect to the mobile phone terminal 30. This selection can be made by calling a device address of a device other than the camera 10 registered in the camera 10 on the liquid crystal monitor 15 and designating the device address of the target mobile phone terminal 30 from the device address.

  The bar code 35 indicates the device address and device name or device category of the mobile phone terminal 30, and the device of the mobile phone terminal 30 is used in the camera 10 by the device address acquisition processing routine as in the examples of FIGS. If it is configured to acquire the address and the device name or the device category, the user can easily and surely select the target mobile phone terminal 30 by judging together with the device name or the device category.

  Next, in step 73, the user performs an object push operation on the camera 10 side, and transmits information from the camera 10 to the mobile phone terminal 30. As a result, in step 74, information is received by the mobile phone terminal 30.

  Specifically, for example, image information obtained by photographing a person or a landscape with the camera 10 is transmitted from the camera 10 to the mobile phone terminal 30, and attached to an email created on the mobile phone terminal 30, It can be transmitted from the mobile phone terminal 30 through a mobile phone line.

  It should be noted that the device address acquisition processing routine can be configured so that the CPU 23 can proceed to the connection phase after the CPU 23 registers the device address in step 48, 58 or 68 of FIG. 3, FIG. 4 or FIG.

  In this case, after registering the device address in step 48, 58 or 68, the CPU 23 displays on the liquid crystal monitor 15 whether or not to shift to the connection phase, such as “Do you want to send data”. When the user performs an operation to shift to the connection phase, it is assumed that the push server has already been selected, and the transmission destination device (push server) is set to the push server mode on the LCD monitor 15, A device address acquisition process is performed so that an image to be transmitted is called on the LCD monitor 15 to indicate that an object push operation should be performed, and when the user performs an operation not to shift to the connection phase, the process is terminated as it is. Configure the routine.

  When the user shifts to the connection phase, the mobile phone terminal 30 is set to the push server mode according to the above display, and the camera 10 calls an image to be transmitted on the liquid crystal monitor 15 and performs an object push operation.

  The device address of the mobile phone terminal 30 is indicated by a two-dimensional bar code 37 such as a cyber code (registered trademark) as shown in FIG. 7 and displayed on the liquid crystal display 32, and this is photographed by the camera 10. The system may be configured.

  The embodiment described above is a case where the push client is the digital still camera 10 and the push server is the mobile phone terminal 30. However, in the present invention, for example, the push client is a camera such as a digital still camera. A system in which the push server is a PC (personal computer) and image data obtained by the camera is transmitted to the PC by wireless communication using Bluetooth, or a mobile phone terminal with a camera (with a built-in camera) by the push client It can also be applied to a system in which the push server is a headset and music data downloaded to a mobile phone terminal from a web site on the Internet is transmitted to the headset by wireless communication using Bluetooth. .

  The present invention is also an information processing terminal such as a PC in which a push client has an interface unit such as a USB interface for connection with an external camera and can capture image information from the external camera. The present invention can also be applied to a system in which the server is a device such as a printer or a modem and image data is transmitted from an information processing terminal such as a PC to a device such as a printer or a modem by wireless communication using Bluetooth.

  In this case, an image indicating the device address of a device such as a printer or modem is taken by an external camera connected to an information processing terminal such as a PC, and the obtained image information is processed by the information processing terminal such as a PC. By doing so, the system is configured so that a device address of a device such as a printer or a modem is acquired in an information processing terminal such as a PC.

  Furthermore, a method other than Bluetooth can be used as a wireless communication method between the information processing terminal that is the transmitting device and the target device that is the receiving device. Also in this case, in the present invention, information for uniquely specifying a device is defined as a device address.
