BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an apparatus and a method for short distance communication in a mobile terminal. More particularly, the present invention relates to an apparatus and a method for reading an image in a mobile terminal to communicate with a neighbor apparatus corresponding to the image.
2. Description of the Related Art
Use of mobile terminals has rapidly increased since the mobile terminals provide a wide variety of services and convenience in portability. Therefore, service providers (i.e., terminal manufacturers) have competitively developed terminals having even more convenient functions in order to attract more users.
For example, mobile terminals now provide functions such as a phonebook, games, a scheduler, a Short Message Service (SMS), a Multimedia Message Service (MMS), a broadcast message service, an Internet service, an Electronic (E)-mail, a morning call, a Motion Picture Expert Group Audio Layer-3 (MP3) player, a digital camera, and the like.
Additionally, mobile terminals now provide and support various services such as use of a headset, playing of music, printing and transmitting files, and the like through a Bluetooth function, which is a technique for communication between terminals existing at a short distance.
To use a Bluetooth function, a mobile terminal first searches for neighboring devices that also support the Bluetooth function. After the neighboring devices are found, the mobile terminal performs a pairing process by determining whether communication with any of the neighboring Bluetooth devices is possible in order to establish a communication state. That is, to use the Bluetooth function, the mobile terminal first searches for neighboring devices that also support the Bluetooth function, generates a list of the Bluetooth available devices, and then selects a Bluetooth device for connection.
As described above, the mobile terminal selects a Bluetooth device from the list of neighboring connectable Bluetooth devices, and communicates with the selected Bluetooth device to perform a service corresponding to the Bluetooth device.
However, according to the above-described method, a user must search for Bluetooth devices and select a Bluetooth device to be connected whenever the user desires to use a service. Also, the user of the mobile terminal must view the various model names of the Bluetooth devices in order to select and connect to a relevant Bluetooth device. Therefore, a user who is not accustomed to the model names may be inconvenienced when connecting to the relevant device.
Additionally, when the mobile terminal performs the process of searching for neighboring Bluetooth devices, the mobile terminal consumes power.

In addition, the mobile terminal may perform communication with a neighbor apparatus using a short distance communication method such as Bluetooth communication, Infrared communication, PictBridge, and the like.
FIG. 1 is a block diagram illustrating a mobile terminal for establishing a communication connection with a neighbor apparatus using an image according to an exemplary embodiment of the present invention.
Referring to FIG. 1, the mobile terminal includes a controller 100, an apparatus connector 102, a memory unit 108, an input unit 110, a display unit 112, and a communication unit 114. The apparatus connector 102 may include an image capturing unit 104 and an apparatus information storage unit 106. The portable terminal may include additional units that are not illustrated here merely for sake of clarity. Similarly, the functionality of two or more of the above units may be integrated into a single component.
The controller 100 of the mobile terminal controls an overall operation of the mobile terminal. For example, the controller 100 controls a process for voice communication and data communication. In addition to the general operations, according to an exemplary embodiment of the present invention, the controller 100 reads an image of an apparatus to intuitively provide information regarding the apparatus for connection using short distance communication. Additionally, according to an exemplary embodiment of the present invention, the controller 100 reduces power consumption of the mobile terminal by omitting a process of searching for the neighbor apparatus when using short distance communication.
To perform the above operations, the controller 100 controls the apparatus connector 102 to obtain an image of a neighbor apparatus to which a user desires to connect. The controller 100 also controls connection with the relevant neighbor apparatus using information corresponding to the obtained image.
According to an exemplary implementation, the apparatus connector 102 determines the type of neighbor apparatus to which the user desires to connect by capturing an image or reading a stored image under control of the controller 100.
Additionally, the apparatus connector 102 obtains information corresponding to the determined neighbor apparatus under control of the controller 100 to establish a communication connection with the neighbor apparatus.
The image capturing unit 104 of the apparatus connector 102 includes a camera. Using the camera, the image capturing unit 104 obtains an image of the neighbor apparatus to which the user desires to connect. The apparatus information storage unit 106 stores information required for communication corresponding to a plurality of neighbor apparatuses. The apparatus information storage unit 106 may be included in the memory unit 108.
The memory unit 108 includes, for example, Read Only Memory (ROM), Random Access Memory (RAM), flash ROM, and the like. The ROM stores microcode (i.e., code) of programs for processes and controls of the controller 100 and the apparatus connecting unit 102, and various reference data.
The RAM serves as a working memory of the controller 100 and stores temporary data occurring during execution of various programs. The flash ROM stores various updatable data for storage such as information of a phonebook, calling messages, received messages, and a user's touch input point.
The input unit 110 includes a plurality of function keys such as numerical key buttons of 0 to 9, a menu button, a cancel button, an OK button, a TALK button, an END button, an Internet access button, navigation key buttons, letter input keys, and the like. The input unit 110 provides key input data corresponding to a key pressed by a user to the controller 100. These keys are merely examples of keys which may make up the input unit 110. That is, the input unit may include additional or different keys, or different input mechanisms through which the user supplies input to the portable terminal.
The display unit 112 displays status information generated during an operation of the mobile terminal, a limited number of letters, a large amount of moving images, still images, and the like. The display unit 112 may be a color Liquid Crystal Display (LCD), an Active Mode Organic Light Emitting Diode (AMOLED), and the like. The display unit 112 may include a touch input device. When the display unit 112 having the touch input device is applied to a touch input type mobile terminal, the display unit 112 may serve as an input unit.
The communication unit 114 transmits/receives a Radio Frequency (RF) signal of data input/output via an antenna (not illustrated). For example, during transmission, the communication unit 114 channel-codes and spreads data to be transmitted, and then performs an RF process on the signal to transmit the signal. During reception, the communication unit 114 converts a received RF signal into a baseband signal, and despreads and channel-decodes the baseband signal to recover data.
The functions of the apparatus connector 102 may be performed by the controller 100 of the mobile terminal. Separate configuration and illustration of the apparatus connector 102 are for exemplary purpose only and for convenience in description, and are not to be construed as limiting the scope of the present invention. It would be obvious to those skilled in the art that various modifications may be made within the scope of the present invention. For example, all of the functions of the apparatus connector 102 may be processed by the controller 100.
An exemplary apparatus for reducing a process of searching for a neighbor apparatus, and intuitively providing information regarding the neighbor apparatus to be connected during communication with the neighbor apparatus in a mobile terminal has been described above. An exemplary method for intuitively providing information regarding a neighbor apparatus by reading a corresponding image is described below.
FIG. 2 is a flowchart illustrating a process for storing information required for establishing a communication connection with a neighbor apparatus in a mobile terminal according to an exemplary embodiment of the present invention.
Referring to FIG. 2, the mobile terminal captures an image of a neighbor apparatus and determines the captured apparatus in step 201.
The mobile terminal determines whether communication with the determined apparatus has been performed before in step 203.
If it is determined in step 203 that communication with the neighbor apparatus has been performed before, the mobile terminal assumes that information required for communication with the relevant neighbor apparatus has been stored and does not store separate information. The mobile terminal then ends the present algorithm.
In contrast, if it is determined in step 203 that communication with the neighbor apparatus has not been performed before, the mobile terminal determines information required to establish a communication connection with the captured apparatus in step 205, and stores the determined information in step 207.
The information required to establish a communication connection with the captured apparatus may be a model name, an ID, a connection address, and the like. The mobile terminal may directly input the information of the apparatus to be connected, or omit a process of inputting the relevant information every time by storing the relevant information during initial communication.
After that, the mobile terminal ends the present algorithm.
FIG. 3 is a flowchart illustrating a process for establishing a communication connection with a neighbor apparatus in a mobile terminal according to an exemplary embodiment of the present invention.
Referring to FIG. 3, the mobile terminal determines whether an event for connection with a neighbor apparatus occurs in step 301. Here, the event for connection with the neighbor apparatus denotes an event for communication with an existing neighbor apparatus using short distance communication.
If it is determined in step 301 that the event for connection with the neighbor apparatus does not occur, the mobile terminal performs a relevant function (e.g., a standby mode) in step 317.
In contrast, if it is determined in step 301 that the event for connection with the neighbor apparatus occurs, the mobile terminal operates a camera that can capture an image in step 303, and captures an image of the neighbor apparatus to be connected in step 305. Here, according to an exemplary embodiment of the present invention, instead of searching for an apparatus existing in the neighborhood, the mobile terminal captures an image of the apparatus to be connected using the image of the apparatus. In addition, as described above, the mobile terminal may load an image already stored in the mobile terminal to obtain the image of the apparatus without capturing an image.
The mobile terminal determines the apparatus captured by the user of the mobile terminal, that is, the type of the apparatus with which the user desires to communicate using the image (captured in step 305) in step 307, and obtains information required to establish a communication connection with the apparatus (determined in step 307) in step 309. Here, the information required for the communication connection may be a model name, an ID, a connection address, and the like of the apparatus to be connected. The mobile terminal may store information used for communication connection with the relevant neighbor apparatus during initial communication with the relevant neighbor apparatus, or store information input by the user. Accordingly, the mobile terminal obtains information regarding the apparatus corresponding to the captured image from the information stored in advance.
The mobile terminal performs a communication connection process with the relevant apparatus using the information (obtained in step 309) in step 311.
In step 313, the mobile terminal determines whether the connection with the apparatus is completed.
If it is determined in step 313 that the connection has not been completed, the mobile terminal re-performs the connection process with the relevant neighbor apparatus using the information (obtained in step 309) in step 311.
In contrast, if it is determined in step 313 that the connection has been completed, the mobile terminal performs communication with the relevant neighbor apparatus in step 315, and ends the present algorithm.
Though an exemplary method that allows the user of the mobile terminal to determine a neighbor apparatus to be connected using a captured image has been described with reference to FIG. 3, the user may determine a neighbor apparatus to be connected using a stored image rather than a captured image according to an exemplary embodiment of the present invention.
FIGS. 4A and 4B are views comparing processes of establishing a communication connection with a neighbor apparatus in a conventional mobile terminal and a mobile terminal according to an exemplary embodiment of the present invention.
FIG. 4A is a view illustrating a process for establishing a communication connection with a neighbor apparatus in a conventional mobile terminal.
Referring to FIG. 4A, the mobile terminal performs a search process to determine neighboring apparatuses with which the mobile terminal may connect and perform communication in step 401.
In the example of FIG. 4A, the mobile terminal that has performed the above-described searching process determines that a television and a Motion Picture Expert Group Audio Layer-3 (MP3) player exist in the neighborhood using information received from each of the neighbor apparatuses.
After that, the mobile terminal allows a user to select a neighbor apparatus for connection. For example, assuming that the user selects the television in step 403 as an apparatus with which the user desires to communicate, the mobile terminal communicates with the television to obtain information required for the connection in step 405, and then connects with the television using the obtained information in step 407.
FIG. 4B is view illustrating a process for establishing a communication connection with a neighbor apparatus in a mobile terminal according to an exemplary embodiment of the present invention.
Referring to FIG. 4B, the mobile terminal does not perform the search process that was performed by the conventional mobile terminal, that is, a process of determining apparatuses existing in the neighborhood.
Instead, according to an exemplary embodiment of the present invention, the mobile terminal determines a neighbor apparatus with which the user desires to communicate using an image, and establishes a communication connection using information stored in advance.
In the example of FIG. 4B, the mobile terminal desires to communicate with the neighboring television. To establish the communication connection with the television, the mobile terminal captures an image of the television in step 410. In an exemplary implementation, the mobile terminal may capture and store images of apparatuses existing in the neighborhood in advance. In that case, the mobile terminal does not perform a separate image capturing process each time the user desires to connect to a neighbor apparatus, but instead loads the appropriate image stored in advance.
Having obtained the image in step 410, the mobile terminal reads the image and determines that the apparatus to which the user desires to connect is a television. Therefore, the mobile terminal obtains information required for connection with the television in step 412 and connects with the television using the relevant information in step 414. In an exemplary implementation, the mobile terminal obtains the information required for connection from information stored in advance.
As described above, a mobile terminal according to an exemplary embodiment of the present invention may reduce a process of searching for a neighbor apparatus, and intuitively provide information regarding an apparatus to which a user desires to connect by reading an image of the apparatus. In contrast, the conventional mobile terminal searches for a neighbor apparatus and provides a result thereof as information regarding the relevant model. In addition, a mobile terminal according to an exemplary embodiment of the present invention may prevent a power consumption problem of the mobile terminal by omitting a process of searching for a neighbor apparatus.
While the invention has been shown and described with reference to certain exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
