It is also possible to detect the position of the image display unit 160 in the image display region formed by the image display unit 160.

  For example, as shown in FIG. 8, when the image display area A2 is formed by the mobile phone terminals 100A to 100D, the mobile phone terminal 100A does not directly contact the mobile phone terminal 100D (similarly, the mobile phone terminal 100B And does not directly contact the mobile phone terminal 100C).

  In such a case, the mobile phone terminals 100A to 100D can exchange group maps (see FIGS. 6A to 6D). The position detection unit 105 of the mobile phone terminals 100A to 100D is based on the detection results by the magnetic sensors 171T, B, L, and R, the group map stored in the storage unit 107, and the group map received via the communication unit 103. Thus, the positions of the image display surfaces 161A to 161D in the image display area A2 are detected. A method for detecting the position of the image display unit 160 in the image display area will be described later.

  The storage unit 107 stores the group map received via the communication unit 103 and the group map generated by the display processing unit 111. The storage unit 107 also stores a compatibility check list, a multi-monitor layout list, and screen layout information used in the display processing unit 111.

  The TV tuner unit 109 includes a tuner that receives digital television broadcasts. The TV tuner unit 109 outputs image data (specifically, moving image data) and audio data to the display processing unit 111 based on the received digital television broadcast signal. In the present embodiment, the TV tuner unit 109 constitutes an image data receiving unit.

  Based on the position of the image display unit 160 in the image display area detected by the position detection unit 105, the display processing unit 111 causes the image display unit 160 to display a part of the entire image corresponding to the position.

  For example, as shown in FIG. 7, when the position detection unit 105 detects that the position of the image display surface 161A in the image display area A1 is on the upper side (or the left side) of the image display surface 161B, the display processing unit 111 Then, a part of the entire image is displayed on the image display unit 160 as follows.

  That is, the display processing unit 111 divides the entire image (see FIG. 10A) displayed on the image display unit 160 in a state where the mobile phone terminal 100A is not in contact with another mobile phone terminal, and is enlarged. The upper part is displayed on the image display unit 160 (see FIG. 10B).

  Further, the display processing unit 111 generates a group map corresponding to the image display area based on the detection result by the position detection unit 105.

  For example, the display processing unit 111 generates a group map (see FIG. 6B) corresponding to the image display area A1 based on the detection result by the position detection unit 105. Note that the display processing unit 111 can appropriately generate a group map as shown in FIGS. 6A to 6D based on the detection result by the position detection unit 105.

  Furthermore, the display processing unit 111 can determine whether or not an image display area can be formed together with another mobile phone terminal that has come into contact, based on the function information acquired by the information acquisition unit 101. In the present embodiment, the display processing unit 111 constitutes a determination unit.

  Specifically, the display processing unit 111 displays the image display area together with the other mobile phone terminals that are in contact with each other based on the compatibility check list shown in FIG. 5A and the state check list shown in FIG. Whether or not can be formed is determined.

  The compatibility check list is acquired via the magnetic sensors 171T, B, L, and R, and the state check list is acquired from another mobile phone terminal via the communication unit 103. Further, the display processing unit 111 can generate and update a state check list according to the state of the mobile phone terminal 100.

  First, based on the compatibility check list, the display processing unit 111 is compatible with the mobile phone terminal 100 and another mobile phone terminal that is in contact, that is, can the display processing unit 111 operate in cooperation with the other mobile phone terminal? Determine whether or not. In FIG. 5A, A to D indicate the model ID of the mobile phone terminal. In addition, “◯” indicates that cooperation is possible, and “×” indicates that cooperation is not possible.

  Next, the display processing unit 111 determines whether or not cooperation is possible based on the state check list. In FIG. 5B, the column indicates the function of the mobile phone terminal 100, and the row indicates the function of another mobile phone terminal that is in contact. In addition, “◯” indicates that cooperation is possible, and “×” indicates that cooperation is not possible. For example, in the state check list shown in FIG. 5B, viewing of digital television broadcasting (“viewing” in the figure) can be currently linked, that is, an image display area (multi-monitor) can be formed. It is shown that.

  Further, the display processing unit 111 determines whether or not the image display area formed together with the other mobile phone terminal in contact with the layout included in the multi-monitor layout list based on the multi-monitor layout list. judge. The multi-monitor layout list includes the following layouts, for example.

320 × 480 (aspect ratio 2: 3, see FIG. 7)
640 × 480 (aspect ratio 4: 3, see FIG. 8)
・ 960 × 720 (Aspect ratio 4: 3)
1280 × 720 (aspect ratio 16: 9, see FIG. 9)
The display processing unit 111 determines whether or not an image display area can be formed together with the other mobile phone terminal in contact by such a determination process.

  Further, the display processing unit 111 can display an image in the image display area in accordance with the layout information (hereinafter referred to as screen layout information) of the image display area specified by the user.

  For example, in the case of the image display area A1, as shown in FIG. 10C, the display processing unit 111 displays a video on the image display surface 161A and displays the contents of the data broadcast on the image display surface 161B. be able to. Further, as shown in FIG. 10D, the display processing unit 111 displays an image on the image display surface 161A and the image display surface 161B so that the longitudinal directions of the image display surface 161A and the image display surface 161B are vertical. It can also be displayed.

  Further, when it is detected that another mobile phone terminal that has been in contact with the magnetic sensors 171T, B, L, and R is separated from the mobile phone terminal 100, the display processing unit 111 displays a part of the entire image as an image. The processing to be displayed on the unit 160 can be ended. As a result, when the process ends, the previous image display unit 160 displays a normal image based on the image data output by the TV tuner unit 109.

  The mobile phone function unit 113 provides functions as a mobile phone terminal such as voice calls and transmission / reception of electronic mail.

  The image display unit 160 displays an image on the image display surface 161 based on the image data. Specifically, the image is displayed based on the image data output by the display processing unit 111 or the image data output by the mobile phone function unit 113.

(Operation of mobile terminal device)
Next, the operation of the mobile phone terminal 100 described above will be described. Specifically, an operation in which the mobile phone terminal 100A forms one large image display area (multi-monitor) together with other mobile phone terminals will be described.

  FIG. 4 shows an operation flow in which the mobile phone terminal 100A forms an image display area (multi-monitor) together with other mobile phone terminals. Here, prior to this operation, as shown in FIG. 7, it is assumed that the mobile phone terminal 100A is in contact with the mobile phone terminal 100B and grouped with the mobile phone terminal 100B. In such a state, the mobile phone terminal 100A (mobile phone terminal 100B) further contacts the mobile phone terminal 100C (mobile phone terminal 100D), and the mobile phone terminals 100A to 100D display images according to the operation flow shown in FIG. A process of forming the display area A2 (see FIG. 8) will be described.

  As shown in FIG. 4, in step S10, the mobile phone terminal 100A searches for another mobile phone terminal. Specifically, the mobile phone terminal 100A detects whether or not the mobile phone terminal 100A is in contact with another mobile phone terminal using the magnetic sensors 171T, B, L, and R.

  In step S <b> 20, the mobile phone terminal 100 </ b> A determines whether or not the current group release pattern has been detected. Specifically, the mobile phone terminal 100A determines whether or not the cancellation of the group (group 3 shown in FIG. 6B) with the mobile phone terminal 100B has been detected. The group release pattern includes making / receiving voice calls, sending / receiving e-mails, and canceling reception of digital television broadcasts. Further, the case where the mobile phone terminal 100B is detected to be separated by the magnetic sensors 171T, B, L, R is also included in the group release pattern.

  When the release pattern is detected (YES in step S20), in step S30, the mobile phone terminal 100A deletes the group map. When the group map is deleted, the mobile phone terminal 100A ends the formation of the multi-monitor with the mobile phone terminal 100B.

  When the release pattern is not detected (NO in step S20), in step S40, the mobile phone terminal 100A determines whether or not it further contacts another mobile phone terminal.

  When further contact with another mobile phone terminal (YES in step S40), in step S60, the mobile phone terminal 100A determines whether or not cooperation with the other mobile phone terminal is possible. Here, as shown in FIG. 8, it is assumed that the mobile phone terminal 100A further contacts the mobile phone terminal 100C.

  The mobile phone terminal 100A reads the functional information stored in the electronic tag 172T of the mobile phone terminal 100C, specifically, the compatibility check list (or the model ID of the mobile phone terminal 100C) via the magnetic sensor 171T. . Based on the function information read from the electronic tag 172T of the mobile phone terminal 100C and the compatibility check list (see FIG. 5A) stored in the storage unit 107, the mobile phone terminal 100A and the mobile phone terminal 100C Whether or not is compatible.

  Further, when it is determined that the mobile phone terminal 100A is compatible with the mobile phone terminal 100C, whether or not the mobile phone terminal 100A can currently cooperate with the mobile phone terminal 100C based on the state check list (see FIG. 5B). Determine whether.

  Note that the processing in step S60 may be executed not only between the mobile phone terminal 100A and the mobile phone terminal 100C but also between the mobile phone terminal 100B and the mobile phone terminal 100D. Alternatively, the function information related to the mobile phone terminal 100B may be provided to the mobile phone terminal 100C via the mobile phone terminal 100A. Similarly, the function information related to the mobile phone terminal 100D may be provided to the mobile phone terminal 100A via the mobile phone terminal 100C.

  On the other hand, when the mobile phone terminal is not further in contact with the mobile phone terminal (NO in step S40), or when it is determined that cooperation with the other mobile phone terminal is impossible (NO in step S60), the mobile phone terminal 100A The operation for forming the display area (multi-monitor) is terminated.

  In step S70, the mobile phone terminal 100A transmits and receives the current group map. Specifically, the mobile phone terminal 100A transmits to the mobile phone terminal 100C a group map that includes the group 3 shown in FIG. 6B. In addition, the mobile phone terminal 100A receives a group map containing the group 4 shown in FIG. 6B from the mobile phone terminal 100C.

  In step S80, the cellular phone terminal 100A generates a temporary group map based on the transmitted and received group maps (group 3 and group 4). Specifically, the mobile phone terminal 100A generates a group map that includes the group 7 shown in FIG.

  In step S90, the mobile phone terminal 100A determines whether grouping according to the temporary group map is possible based on the generated temporary group map. Specifically, the mobile phone terminal 100A determines whether grouping is possible based on the multi-monitor layout list.

  Since the group map including the group 7 shown in FIG. 6D is a layout (640 × 480) included in the multi-monitor layout list, the mobile phone terminal 100A determines that grouping is possible.

  If grouping is possible (YES in step S90), in step S100, the mobile phone terminal 100A determines whether or not a parent device has been designated. Specifically, the image display unit 160 of the mobile phone terminal 100A (and the mobile phone terminals 100B to 100D) displays a message such as “Start multi-monitor. Is done.
