At this time, for example, when the user tries to communicate with the wireless communication 100 and the printer 8, it is necessary to designate the printer 8 as a communication partner from the communicable printer 8, digital camera 9, and PDA 11.

  Therefore, the user takes a picture of the printer 8 using the camera function of the wireless communication terminal 100. Then, the wireless communication terminal 100 creates pattern data from the captured image, finds pattern data of the printer 8 that almost matches the registered pattern data in the table, and reads connection information of the printer 8. In this way, the wireless communication terminal 100 can easily specify the printer 8 as a connection partner from a plurality of wireless communication devices without being confused by the selection means.

  Then, the structure of the radio | wireless communication terminal 100 concerning Embodiment 1 of this invention is demonstrated using FIG. FIG. 2 is an example of a configuration diagram of the wireless communication terminal 100 according to the first embodiment of the present invention. The wireless communication terminal 100 is, for example, a mobile phone that is separately provided with a camera function and a wireless communication function in addition to a call function, such as a control unit 101, a photographing unit 102, a patterning unit 103, a storage unit 104, and a wireless communication unit. 105, a display means 106, an input means 107, and a battery 108. The control unit 101 is connected to each of the photographing unit 102, the patterning unit 103, the storage unit 104, the wireless communication unit 105, the display unit 106, the input unit 107, and the battery 108.

  The control unit 101 executes various types of control in the wireless communication terminal 100, and includes, for example, a CPU (Central Processing Unit). The photographing unit 102 is, for example, a digital camera and has a function of photographing a still image. The patterning unit 103 has a function of extracting features from information of still image data and converting the information into pattern information. The control unit 101 may perform this using software, or may use dedicated hardware. May be used. The pattern information may be only information indicating the outer shape of another communication device to be imaged, and any one of identification information that can be distinguished from other communication devices, such as outer shape, color information, and surface shape information. Alternatively, the information may be a combination of a plurality of combinations.

The storage unit 104 is a memory such as a RAM (Random Access Memory), for example, a program for operating the wireless communication apparatus 100, image data shot by the shooting unit 102, pattern information created by the patterning unit 103, Data such as an address for communicating with another wireless communication terminal, connection information such as an encryption key, and the like are stored. At this time, the pattern information and the connection information are stored in a table corresponding to each other.

The wireless communication means 105 is means for performing wireless communication with other wireless communication terminals, and specifically includes a wireless processing circuit, an antenna, and the like. The display unit 106 is, for example, a liquid crystal display and has a function of displaying an image captured by the imaging unit 102, a message to the user, and the like. The input unit 107 is, for example, a key or a button, and has a function of allowing the user to send information to the wireless communication terminal 100. The battery 108 is a power source that drives the wireless communication terminal 100.

Next, processing of the portable terminal device according to the present invention will be described using the flowchart shown in FIG.

First, the user takes a picture of a wireless communication device desired to communicate with the wireless communication terminal 100 using the photographing means 102 (S301). If you want to communicate with a previously registered wireless communication device, the same orientation as possible when the image was taken at the time of previous registration so that the previously registered pattern and the pattern created from the image taken this time will match. It is desirable to shoot at the same distance. The captured image is stored in the storage unit 104.

Subsequently, the patterning unit 103 reads the image photographed by the photographing unit 102 from the storage unit 104 and converts it into pattern information (S302). For example, as shown in Japanese Patent No. 285907 edge detection method, the patterning means may acquire edge information and use the edge information itself, or further reduce the resolution of the edge information. The information may be used, or the image information may be converted into pattern information by adding color distribution information of a portion surrounded by edges.

Next, the control unit 101 performs communication by determining whether the pattern information created by the patterning unit 103 matches or is very close to the pattern information registered and stored in the storage unit 104. It is determined whether the desired wireless communication device has been registered (S303). The degree of matching may be set or changed in the patterning unit 103 using the input unit 107. If it is determined that the information has been registered, the storage unit 101 reads connection information such as the address of the wireless communication device to be connected and the encryption key from the table registered in the storage unit 104 (S304).

When it is determined that the wireless communication device is not registered or the wireless communication device is used for the first time, the control unit 101 causes the display unit 106 to display a message to that effect. The user inputs connection information such as the address of the wireless communication device and the encryption key using the input means 107 (S305). If it is determined that it is not registered, the connection procedure may be terminated without performing a new registration operation. When the input is completed, the control unit 101 registers the pattern information and the connection information such as the address of the wireless communication device and the encryption key in the storage unit 104 (S306).

When the connection information is read or input, the wireless communication terminal 100 can connect to another wireless communication device using the connection information and perform wireless communication (S307).

If you want to communicate with a previously registered wireless communication device, the same orientation as possible when the image was taken at the time of previous registration so that the previously registered pattern and the pattern created from the image taken this time will match. It is desirable to shoot at the same distance. The captured image is stored in the storage unit 104.

Subsequently, the patterning unit 103 converts the image photographed by the photographing unit 102 into pattern information (S402). For example, the patterning means may acquire edge information and use the edge information itself, or use information obtained by reducing the resolution of the edge information, or a portion surrounded by edges. The image information may be converted into pattern information by adding the color distribution information.

Next, by determining whether the pattern information created by the patterning unit 103 matches or is very close to the pattern information registered and stored in the storage unit 104, the wireless communication device that wants to communicate is determined. It is determined whether it has been registered (S403). When it is determined that registration has been completed, the control unit 101 reads connection information such as the address of the wireless communication device to be connected and the encryption key from the table registered in the storage unit 104 (S404).

When it is determined that the wireless communication device is not registered or the wireless communication device is used for the first time, the control unit 101 uses the wireless communication unit 105 to search for a wireless communication device that can communicate by outputting radio waves (S405). Specifically, the wireless communication terminal 100 transmits packet data referred to as an ID packet in order to establish a connection state. The wireless communication device that has received it transmits packet data called an FHS packet that conveys its attributes to the wireless communication apparatus 100. After the transmission / reception of the ID packet and the FHS packet is repeated, the wireless communication device 100 enters a connected state. If it is determined that it is not registered, the connection procedure may be terminated without performing a new registration operation.

When there are a plurality of communicable wireless communication devices, the user selects a wireless communication device that performs communication using the input unit 107 or the like (S406). When a wireless communication device for communication is determined, the control unit 101 registers pattern information and connection information such as an address of the wireless communication device and an encryption key in the storage unit 104. (S407).

When the connection information is read or registered, the wireless communication terminal 100 can connect to another wireless communication device using the connection information and perform wireless communication (S408).

In this way, when performing wireless communication with a wireless communication device that has been registered once, the user can specify a wireless communication device that performs wireless communication reliably and without any trouble.

In the above example, pattern information was created by photographing the wireless communication device of the other party, but characters or images representing addresses and encryption keys were photographed and character recognition or image recognition was performed to generate a code. It may be registered together with the pattern information.
In the above example, a still image is used as an image used for patterning. However, a moving image may be used as long as it can be patterned.
In the above example, one image is used for patterning. However, this may be performed using a plurality of images. By doing so, malfunctions when checking the pattern are reduced.
