It has a function to move or copy to a folder.

  Next, functional blocks of the projector 100 having such functions will be described. FIG. 2 is a functional block diagram of the projector 100 according to the first embodiment. The projector 100 includes a receiving unit 110 that receives instruction sign information and image information from the PC 200, a transmission unit 120 that transmits control information and the like to the PC 200, a processing unit 130, a storage unit 140 that stores data, and an image. Is included. The processing unit 130 includes a determination unit 132 that performs determination based on the instruction sign information, a control information generation unit 134 that generates control information, and an update unit 136 that updates data in the storage unit 140. . In addition, the storage unit 140 indicates the area of the shared folder and the shared file in the file shared image, the area data 142 indicating the area for displaying the image based on the image information transmitted from the PC 200 in the normal image, the position of the cursor image, and the like. Instruction data 144 and the like are stored.

  The area data 142 may include data indicating the IP address of the PC 200 constituting the file sharing image, and the instruction data 144 includes identification information (for example, IP address, PC name, user name) of the PC 200 corresponding to the cursor image. Name), data indicating the state of the cursor image (for example, during a shared file copy operation, a shared file move operation, a simple operation, a non-display, etc.), and the like.

  The projector 100 may function as each of these units using the following hardware. For example, the projector 100 includes a reception unit 110, a transmission unit 120, a wireless communication unit, a wired communication unit, a processing unit 130, a CPU, a storage unit 140, a RAM, a projection unit 190, an image processing circuit, a lamp, a liquid crystal panel, A liquid crystal driving circuit, a lens, or the like may be used. Note that the reception unit 110 and the transmission unit 120 may be integrated as a communication unit.

  Next, a procedure for projecting a file shared image or the like in this embodiment will be described. FIG. 3 is a flowchart showing a projection procedure in the first embodiment. The user gives an instruction to project a file sharing image by operating a keyboard, a mouse, or the like on the PC 200. The determination unit 132 determines whether projection instruction information indicating a file sharing image projection instruction is received from the PC 200 by the reception unit 110 (step S1).

  When the projection instruction information is received, the control information generation unit 134 generates transmission control information (second control information) for transmitting shared information regarding the shared folder and the shared file based on the area data 142 and the like. The transmitting unit 120 transmits the transmission control information to the destination PC 200 specified by the transmission control information (step S2). The transmission control information may include, for example, information indicating the IP address of the PC 200 constituting the file shared image, information indicating a transmission instruction of shared information indicating the shared folder and the shared file in each PC 200, and the like.

  The determination unit 132 determines whether the shared information has been received from the PC 200 by the reception unit 110 (step S3). When the shared information is received, the update unit 136, for example, the name of the shared folder of each PC 200, the name of the shared file, the area of the shared folder in the file shared image, the area of the shared file in the file shared image according to the shared information The area data 142 is updated so as to update (step S4).

  Further, the determination unit 132 determines whether or not the instruction sign information related to the cursor image (indication sign) is received from the PC 200 by the receiving unit 110 (step S5). For example, when the user operates the mouse in the PC 200 to move the cursor image in the file sharing image while the file sharing image is projected, the PC 200 sets the coordinate position corresponding to the mouse operation and the IP address of the PC 200. The indication sign information shown is transmitted to the projector 100.

  When the instruction marker information is received, the update unit 136 updates the instruction data 144 according to the IP address of the PC 200 included in the instruction marker information, the coordinate information included in the instruction marker information, and the like (step S6). Thereby, the instruction data 144 can indicate an instruction position using a cursor image for each PC 200.

  The projection unit 190 generates a file sharing image based on the area data 142 and the instruction data 144, and projects the file sharing image on a screen or the like (step S7).

  FIG. 4 is a diagram illustrating an example of the file sharing image 400 in the first embodiment. For example, in the file sharing image 400, an individual image 411 (first image) indicating a shared folder and a shared file of the PC 200-1 (first terminal device) is arranged in the upper left area, and the PC 200-2 (second image) is displayed. The individual image 412 (second image) indicating the shared folder and the shared file of the terminal device) is arranged in the upper right area, and the individual image 413 (third image indicating the shared folder and the shared file of the PC 200-3 (third terminal device)). (Third image) is arranged in the lower left area, and an individual image 414 (fourth image) showing the shared folder and shared file of the PC 200-4 (fourth terminal apparatus) is arranged in the lower right area. .

  For example, the user of the PC 200-1 issues an operation start instruction for the cursor image 420 by simultaneously pressing the “CTRL” key and the “1” key on the keyboard of the PC 200-1. In this case, the update unit 136 updates the instruction data 144 to indicate that the cursor image 420 is displayed based on the instruction marker information indicating the operation start instruction.

  Further, for example, in a state where the cursor image 420 is in the shared file A of the shared folder A, the user of the PC 200-1 simultaneously presses the “CTRL” key and the “C” key of the PC 200-1 keyboard (shared file Copy instruction operation), the mouse 200 of the PC 200-1 is moved so that the cursor image 420 moves to the position of the shared folder D, and the "CTRL" key and the "V" key on the keyboard of the PC 200-1 are simultaneously pressed. The paste operation is performed.

  In this case, the update unit 136 updates the area data 142 based on the instruction sign information indicating the copy instruction operation of the shared file (instruction sign information including the copy instruction information), and based on the instruction sign information indicating the pasting operation, The area data 142 is updated.

  Note that the cursor image 420, which is a kind of instruction sign, has an arrow shape, and is displayed with a “C” attached in the case of a copy operation. That is, the projection unit 190 projects the file sharing image 400 that displays the cursor image 420 in a state (first state) marked with “C” in the case of the indicator sign information including the copy instruction information.

  Further, the determination unit 132 copies the shared file by moving the cursor image 420 from the position indicating the shared file to the position of the shared folder to which the shared file belongs based on the instruction sign information, the area data 142, and the instruction data 144. It is determined whether a paste operation has been performed during the operation.

  When the paste operation is performed during the shared file copy operation, the control information generation unit 134 copies the copy destination from the PC 200-1 that is the copy source of the target shared file A1 based on the area data 142 and the instruction data 144. Copy transmission control information (first control information, for example, an FTP command) that causes the PC 200-3 to copy and transmit the shared file A1 is generated, and the transmission unit 120 transmits the copy transmission control information to the PC 200-1. May be. As a result, the shared file A1 in the HDD of the PC 200-1 is copied by the PC 200-1 to the shared folder D in the HDD of the PC 200-3.

  Further, for example, the user of the PC 200-1 issues an operation end instruction for the cursor image 420 by simultaneously pressing the “CTRL” key and the “2” key on the keyboard of the PC 200-1. In this case, the update unit 136 updates the instruction data 144 to indicate that the cursor image 420 is not displayed based on the instruction marker information indicating the operation end instruction.

  When it is determined in step S1 that there is no projection instruction information, or when instruction information indicating a file sharing image projection end instruction is received by the reception unit 110, the projection unit 190 receives image information from each PC 200. Based on the area data 142, a normal image is generated and projected (step S8).

  FIG. 5 is a diagram illustrating an example of a normal image 500 in the first embodiment. For example, in the normal image 500, an individual image 511 indicating an image based on the image information of the PC 200-1 is disposed in the upper left area, and an individual image 512 indicating an image based on the image information of the PC 200-2 is disposed in the upper right area. The individual image 513 indicating an image based on the image information of the PC 200-3 is arranged in the lower left region, and the individual image 514 indicating the image based on the image information of the PC 200-4 is arranged in the lower right region.

  Note that this image information is, for example, information on an image generated by capturing an image being displayed on the PC 200, and may be moving image information or still image information.

  The projector 100 determines whether or not there is an end instruction (step S9), and repeatedly executes the above-described series of processing (steps S1 to S9) until the end instruction is received.

  As described above, according to this embodiment, the projector 100 projects the file sharing image 400 indicating the shared folder and the shared file, and copies the shared file according to the movement of the cursor image 420 in the file sharing image 400. It can be carried out. As a result, the projector 100 can cause the PC 200 to copy a file more easily and visually in a situation where an image is projected using image information from a plurality of PCs 200. As a result, the user can easily distribute materials and the like in meetings and classes.

  Further, according to the present embodiment, the projector 100 can project the file sharing image 400 in accordance with the projection instruction, so that it is possible to make the PC 200 copy the file more easily and visually.

  Further, according to the present embodiment, the projector 100 can project a file sharing image according to the actual sharing situation by using the area data 142 updated based on the sharing information from each PC 200, A change in sharing status (for example, addition or deletion of a shared folder, addition or deletion of a shared file, etc.) can also be handled.

  Further, the projector 100 projects the normal image 500 based on the area data 142, thereby matching the arrangement of the individual images 411 to 414 in the file sharing image 400 with the arrangement of the individual images 511 to 514 in the normal image 500. Therefore, it is possible to cause the PC 200 to copy the file more easily and visually.

  Further, according to the present embodiment, the projector 100 can project the file sharing image 400 in which the cursor image 420 moves beyond the boundary between the individual images 411 to 414 for each PC 200, so that the file can be copied to the PC 200. It can be made simpler and easier to understand visually.

(Second embodiment)
In the first embodiment, copying of a shared file has been described. However, the projector 100 can also move a shared file. FIG. 6 is a diagram illustrating an example of the file sharing image 401 in the second embodiment. The file sharing image 401 is the same image as the file sharing image 400.

  For example, in the state where the cursor image 421 is in the shared file A of the shared folder A, the user of the PC 200-1 simultaneously presses the “CTRL” key and the “X” key on the keyboard of the PC 200-1 (instruction for moving the shared file) By moving the mouse of the PC 200-1 so that the cursor image 420 moves to the position of the shared folder D, and simultaneously pressing the “CTRL” key and the “V” key on the keyboard of the PC 200-1. Perform paste operation. In this case, the update unit 136 updates the area data 142 based on the instruction sign information indicating the movement instruction operation of the shared file (instruction sign information including the movement instruction information), and based on the instruction sign information indicating the pasting operation, The area data 142 is updated.

  Note that the cursor image 421, which is a kind of instruction sign, has an arrow shape, and is displayed with “M” attached in the case of a shared file move operation. In other words, the projection unit 190 projects the file sharing image 401 that displays the cursor image 421 with the “M” attached (second state) in the case of the indicator sign information including the movement instruction information.

  The determination unit 132 moves the shared file by moving the cursor image 420 from the position indicating the shared file to the position of the shared folder to which the shared file belongs based on the instruction sign information, the area data 142, and the instruction data 144. It is determined whether a paste operation has been performed during the operation. When the paste operation is performed during the shared file move operation, the control information generation unit 134 copies the copy destination from the copy source PC 200-1 of the target shared file A1 based on the area data 142 and the instruction data 144. Mobile transmission control information (first control information, for example, FTP command, etc.) for moving and transmitting the shared file A1 to the PC 200-3 is generated, and the transmission unit 120 transmits the mobile transmission control information to the PC 200-1. May be. Thereby, the shared file A1 in the HDD of the PC 200-1 is moved to the shared folder D in the HDD of the PC 200-3 by the PC 200-1.

  As described above, according to this embodiment as well, the projector 100 has the same effects as those of the first embodiment, and allows the PC 200 to move a file more easily and visually.

  Further, according to the present embodiment, the projector 100 can determine what operation is being performed using the instruction data 144 by updating the instruction data 144 according to the instruction content regarding the cursor image 421. In addition, since the cursor images 420 and 421 can be displayed in different states depending on the movement instruction and the copy instruction, it is possible to make the PC 200 perform file movement and the like more visually and easily.

(Other examples)
In addition, application of this invention is not limited to the Example mentioned above, A various deformation | transformation is possible. For example, the update unit 136 updates data related to the cursor image for each user in the instruction data 144 based on the instruction sign information from each PC 200, and the projection unit 190 creates a file shared image including a plurality of cursor images for each user. You may project.

  The display method of the cursor images 420 and 421 is not limited to the above-described embodiment, and may be displayed in different colors, different shapes, different patterns, etc. depending on the operation content. The number of PCs 200 and the number of individual images 411 to 414 and 511 to 514 are not limited to 4, and may be 3 or less, or 5 or more.

  In addition, the instruction data 144 may include authority data indicating authority regarding operations for each user or PC 200, and the determination unit 132 may determine whether or not to permit a copy operation and a move operation based on the authority data.

  The projection unit 190 may display non-shared folders other than the shared folder as the individual images 411 to 414 in addition to the shared folder. In this case, the determination unit 132 may determine that the copy operation or the like for the non-shared folder is invalid based on the area data 142.

  Further, the determination unit 132 determines whether the cursor images 420 and 421 have moved from the position indicating the shared file to the position of the shared folder to which the shared file belongs based on the instruction sign information, and the control information generation unit 134 If the determination result is true, control information for moving or copying the shared file to the destination shared folder may be generated. That is, the movement instruction information and the copy instruction information are not essential, and the control information generation unit 134 may determine whether to move or copy according to the setting in the projector 100. Further, the update unit 136, the area data 142, and the instruction data 144 are not essential. For example, the areas of the individual images 411 to 414 are determined depending on the number of PCs 200, the areas of the individual images 411 to 414 coincide with the areas of the shared folder, and the indicator sign information is information indicating absolute coordinates corresponding to the areas. In some cases, the determination unit 132 can make the above determination without using the area data 142 or the instruction data 144.

  The terminal device is not limited to the PC 200, and may be, for example, a mobile phone, a portable information terminal, a game device, or the like.
