The figure explaining transmission and reception of information with the projector PJ and information terminal device PC1-PC5. 2 is a diagram illustrating an image display system 900 described in Patent Document 1. FIG.

  Hereinafter, an image display system, a multi-screen display method and an image display apparatus in the image display system according to the present invention will be described. In the embodiment described below, the image display device is described as a projector.

  FIG. 1 is a diagram illustrating an image display system 10 according to the embodiment. As shown in FIG. 1, the image display system 10 functions as a projector PJ, a plurality (five) of information terminal devices (referred to as personal computers) PC1, PC2, PC3, PC4, PC5, and a server. Information terminal equipment (hereinafter referred to as a server) SPC, and a projector NET, information processing terminal equipment PC1 to PC5, and a network NET to which the server SPC is connected.

  In the image display system 10 according to the embodiment, each information terminal device PC1 to PC5 is installed in a head office, each branch office, each sales office, etc. (referred to as each department) of a certain company. Further, the projector PJ acquires image information from the information terminal devices installed in each of these departments, and enables images corresponding to the acquired image information to be displayed on a multi-screen on a screen or the like. Although the projector PJ can be installed in each department in the same manner as the information terminal device, in the embodiment, the projector PJ will be described as one unit.

  By the way, as described above, each image information acquired from the information terminal devices PC1 to PC5 corresponds to various materials (for example, materials such as planning documents and sales results) used for a meeting in a company or the like. Image information can be exemplified. For this reason, in the following description, each “image information” acquired from the information terminal devices PC1 to PC5 will be referred to as “material image information”.

  In the image display system configured as described above, the projector PJ transmits a connection establishment response when receiving a connection request from the information terminal devices PC1 to PC5. As a result, the projector PJ is in a state where the connection with the information terminal device is established, and information such as document image information can be exchanged with the information terminal device with which the connection has been established.

  On the other hand, identification information (referred to as terminal identification information) for enabling identification of each information terminal device PC1 is given to the information terminal devices PC1 to PC5. Further, in the information terminal devices PC1 to PC5, material image information handled by a user who uses each information terminal device is stored.

  Each of the information terminal devices PC1 to PC5 transmits the terminal identification information given to each information terminal device to the projector PJ and transmits the terminal identification signal after the connection with the projector PJ is established. Thereafter, control for transmitting the document image information to the projector PJ is performed at a predetermined timing. Such control is performed by a control device (not shown) provided in each of the information terminal devices PC1 to PC5.

  The “predetermined timing after transmitting the terminal identification signal” here is not particularly limited. For example, after a certain time has elapsed after the information terminal device transmits the terminal identification signal. In the case where the projector PJ is set to transmit the document image transmission permission signal to the information terminal device, the information terminal device has received the document image transmission permission signal. Any subsequent timing may be used.

  The projector PJ acquires material image information from the information terminal devices PC1 to PC5, and displays an image corresponding to the acquired material image information (denoted as a material image) on the screen. At this time, the screen is divided into a plurality of display areas according to the number of information terminal devices established with the projector PJ, and is displayed on a multi-screen.

  The server SPC has a user identification information table 300 (see FIG. 2). The user identification information table 300 stores individual user identification information (referred to as user identification information) that enables identification of users who use the information terminal devices PC1 to PC5.

  FIG. 2 is a diagram illustrating an example of the user identification information table 300. In the user identification information table 300, as shown in FIG. 2, the terminal identification information given to each information terminal device PC1 to PC5 and the user identification that can specify the user who uses each information terminal device PC1 to PC5. Information and are stored. In FIG. 2, “No. 1” to “No. 5” represent numbers of the information terminal devices PC1 to PC5, and correspond to the information terminal devices PC1 to PC5. For example, “No. 1” corresponds to the information terminal device PC1, and “No. 2” corresponds to the information terminal device PC2.

  In the embodiment, the terminal identification information uses the computer name of each information terminal device. The user identification information is assumed to be user name information of each user and face image information of each user. In the embodiment, the user name is the department name (branch name, sales office name, etc.) to which the user belongs and the name of the user. The face image information is stored as image files F1 to F5.

  As a specific example of the user identification information table 300, as shown in FIG. 2, for example, for the information terminal device PC1 of “No. 1”, the computer name “PCA00321” of the information terminal device PC1 is used as terminal identification information. ”, The user name of the information terminal device PC1 to which the terminal identification information is given is“ Nagoya Sales Office Kinoshita ”, and the face image of the user is“ image file F1 ”. The user name and the user face image are associated with the terminal identification information (computer name).

  In the user identification information table 300, in fact, as the “user name”, user name information corresponding to each user name is stored, and when the user name information is read, the projector PJ reads the user name information. For example, a user name such as “Nagoya Sales Office Kinoshita” is displayed in a predetermined display area. Similarly, face image information corresponding to each user's face image is stored in each of the image files F1 to F5, and the face image information is read out, so that the projector PJ receives a predetermined face image information. The face image of the user is displayed in the display area.

  Such a user identification information table 300 is stored by the server SPC. For this reason, even when a plurality of projectors are connected to the network NET, the plurality of projectors can share the user identification information table 300. Note that the contents of the user identification information table 300 are changed when the terminal identification information (computer name) and user identification information (user name information and user face image information) of each information terminal device are changed. When devices are added, the latest information can be updated.

  FIG. 3 is a diagram for explaining the projector PJ according to the embodiment. As shown in FIG. 3, the projector PJ according to the embodiment includes an image information input unit 110 to which general image information is input, and an image information processing unit 120 that processes the image information input to the image information input unit 110. An OSD (On Screen Display) processing unit 130, a communication unit 140 capable of exchanging information with other devices (information terminal devices PC1 to PC4 and server SPC) via a network NET, and a remote controller (Referred to as a remote controller) or an operation information input unit 150 for inputting operation information operated by an operation panel, a control device 160 for controlling each unit, and information necessary for the control device 160 to control each unit is stored. Storage unit 170, an image projection unit 180 that projects an image, and a power supply unit 200 that supplies power necessary for the operation of each unit. That.

  Since the image projection unit 180 can use an image projection unit having the same configuration as that of a general projector, the configuration is simplified and schematically shown here.

  As shown in FIG. 3, the image projection unit 180 modulates the light source unit 181 that emits light including red light, green light, and blue light, and red light, green light, and blue light based on image information, respectively. A light modulation element (liquid crystal panel) 182R for red light, a light modulation element (liquid crystal panel) 182G for green light, a light modulation element (liquid crystal panel) 182B for blue light, and a dichroic mirror 183 that separates light from the light source unit , 184, reflection mirrors 185 to 187, a cross dichroic prism 188 that combines color lights modulated by the light modulation elements 182R, 182G, and 182B, a projection lens 189 that projects image light combined by the cross dichroic prism 188 onto the screen SCR, Light source drive unit 190 that drives the light source unit 181 and light that drives the light modulation elements 182R, 182G, and 182B And a regulating device driving section 191. Actually, in addition to these, for example, there are various optical components such as a relay lens and a polarizing plate provided corresponding to each light modulation element, but these are not shown.

  The control device 160 displays a display control function for displaying an image corresponding to the image information input from the image information input unit 110 on the screen SCR, and a material image corresponding to the material image information received via the communication unit 140. A display control function for performing control for multi-screen display on the screen SCR. Note that a display control function for performing control for causing the screen SCR to display multiple screens is also referred to as a “multi-screen display control function”.

  Since the display control function for displaying an image corresponding to the image information input from the image information input unit 110 on the screen SCR is the same as that of a general projector, the multi-screen display control function will be described here. .

  As a control unit for realizing the multi-screen display control function, the control device 160 receives a connection request from the information terminal devices PC1 to PC5 and transmits a connection establishment response to the connection request (not shown). )), The terminal identification information acquisition unit 161 that acquires the terminal identification information transmitted from the information terminal devices PC1 to PC5, and the user identification information that can identify the user who uses the information terminal devices PC1 to PC5. The user identification information acquisition unit 162 and the control for displaying the document image corresponding to the document image information acquired from the information terminal devices PC1 to PC5 on a multi-screen, and displaying the user identification information at a predetermined position in each display area And a multi-screen display control unit 163 that performs control for the control.

  Further, the multi-screen display control unit 163 sets a display area according to the number of information terminal devices that have established a connection with the projector PJ, and controls which information terminal device is assigned to which display area. Also do. For example, if the number of information terminal devices established with the projector PJ is four, the image display surface of the screen SCR is divided into four, and four display areas are set. Display area allocation control is also performed, such as which information terminal apparatus among the information terminal apparatuses is allocated to which display area of the four display areas.

  FIG. 4 is a diagram illustrating a multi-screen display example by the projector PJ. In FIG. 4, the case where the information terminal devices with which the connection with the projector PJ is established is four of the information terminal devices PC1 to PC4 among the information terminal devices PC1 to PC5 is illustrated. For this reason, the screen SCR is divided into four display areas A1 to A4 as shown in FIG. Specifically, the screen is divided into four so that a 2 × 2 display area is set in the horizontal and vertical directions of the display surface of the screen SCR. In this case, it is assumed that the method of dividing into four is divided into four equal parts.

  The display areas A1 to A4 generated in this way are assigned to each information terminal device. In FIG. 4, the information terminal device PC1 is allocated to the display area A1, the information terminal device PC2 is allocated to the display area A2, the information terminal device PC3 is allocated to the display area A3, and the information is displayed to the display area A4. The case where terminal device PC4 is allocated is illustrated.

  In each display area A1 to A4, in addition to the material images G1 to G4 corresponding to the material image information acquired from each information terminal device PC1 to PC4, the user name N1 who uses each information terminal device PC1 to PC4 To N4 and user face images F1 to F4 corresponding to the user names N1 to N4 (the same reference numerals as those of the image files F1 to F4) are displayed, respectively. These user names N1 to N4 and user face images F1 to F4 can be acquired from the user identification information table 300.

  Thus, for example, in the display area A1 on the screen SCR, in addition to the material image G1 acquired from the information terminal device PC1, the user name N1 (“Nagoya Sales Office Kinoshita”) is displayed as user identification information, and The user's face photograph F1 is displayed. In addition, as shown in FIG. 4, these user names and face photographs are located at positions that do not interfere with the display of the material image G1 in the display areas A1 to A4 (for example, at the lower ends of the display areas A1 to A4). It is preferable to set it at a close position.

  FIG. 5 is a flowchart for explaining the operation of the projector PJ. FIG. 5 mainly explains the control performed by the control device 160 of the projector PJ. As shown in FIG. 5, when the projector PJ is powered on (step S1), user identification information corresponding to each user is obtained from the user identification information table 300 (see FIG. 2) stored in the server SPC. Obtain (step S2). In this case, all the information corresponding to each information terminal device PC1 to PC5 stored in the user identification information table 300 is acquired. And the acquired user identification information is preserve | saved at the memory | storage part 170 (step S3). It is assumed that the acquired user identification information is also stored in the storage unit 170 in the “user identification information table” format as shown in FIG.

  Then, the connection request waiting state from the information terminal devices PC1 to PC5 is entered (step S4). When the connection request is received in the connection request waiting state (step S5), the connection is made to the information terminal device issuing the connection request. An establishment response is transmitted (step S6). As a result, the connection between the information terminal device that has issued the connection request and the projector PJ is established.

  Subsequently, the terminal identification information (computer name) from the information terminal device with which connection has been established is awaiting reception (step S7), and the terminal identification information from the information terminal device with which connection has been established in the state of waiting for reception of the terminal identification information. Is received (step S8), a display area is set (step S9).

  The display area is set according to the number of information terminal devices that have established connections. For example, assuming that there are four information terminal devices that have established connections, the screen SCR is divided into four and four display areas are set. And each display area produced | generated by the division | segmentation is allocated to each information terminal device.

  When the display area is set in this way, whether or not the terminal identification information (computer name) of the information terminal device with which the connection has been established has been registered with reference to the user identification information table stored in the storage unit 170. Is determined (step S10). This determination can be made by determining whether or not the terminal identification information (computer name) exists in the user identification information table. Here, when the terminal identification information of the information terminal device has been registered (in the case of “YES” in step S10), user identification information (user name information and user face image information) corresponding to the terminal identification information. ) Is acquired (step S11).

  Subsequently, the user name corresponding to the user name information acquired from the user identification information table and the face image corresponding to the face image information are displayed at a predetermined location in the display area corresponding to each information terminal device (step S12). A material image corresponding to the material image information acquired from the information terminal device is displayed (step S13).

  For example, if the terminal identification information (computer name) received in step S8 is “PCA00321” given to the information terminal device PC1, for example, and the terminal identification information is registered, as shown in FIG. In addition to the document image G1, “Nagoya Sales Office Kinoshita” is displayed as the user name in the display area A1 set corresponding to the information terminal device PC1, and “face” is displayed as the user face image. Image F1 "is displayed.

  In step S10, if the terminal identification information (computer name) of the information terminal device has not been registered in the user identification information table (in the case of “NO” in step S10), the terminal identification information (computer name) is set. The corresponding user name and user face image cannot be acquired. In such a case, the material image corresponding to the material image information acquired from the information terminal device is displayed in the corresponding display area (step S13). At this time, the computer name may be displayed when displaying the document image.

  FIG. 6 is a flowchart for explaining the operation of the information terminal devices PC1 to PC5. FIG. 6 mainly explains control performed by a control device (not shown) of the information terminal devices PC1 to PC5. Here, the operation of the information terminal device PC1 among the information terminal devices PC1 to PC5 will be described.

  As shown in FIG. 6, the information terminal device PC1 starts a program for transmitting the document image information stored in the information terminal device PC1 to the projector PJ (step S21), and requests connection to the projector PJ. Is transmitted (step S22). Then, the connection establishment response is waited for from the projector PJ (step S23). When the connection establishment response is received from the projector PJ in the connection establishment response wait state (step S24), the terminal identification information given to itself is received. (Computer name) is transmitted to the projector PJ (step S25). Thereafter, the document image information is transmitted at a predetermined timing (step S26).

Note that, as described above, the timing for transmitting the material image may be any timing after a certain period of time has elapsed after the information terminal device transmits the terminal identification signal, for example, from the projector PJ. When the image transmission permission signal is set to be transmitted to the information terminal device, the timing may be any timing after the information terminal device receives the document image transmission permission signal.
Further, although the information terminal device PC1 has been described with reference to FIG. 6, the same applies to the other information terminal devices PC2 to PC5.

  FIG. 7 is a diagram for explaining exchange of information between the projector PJ and the information terminal devices PC1 to PC5. In FIG. 7, transmission / reception of information between the projector PJ and one information terminal device (referred to as information terminal device PC1) will be described.
