The IF unit 104 corresponds to the USB interface 28. The operation unit 105 corresponds to the mouse and keyboard 25, and the display unit 106 corresponds to the display 27.

  The PC 2 has the configuration shown in FIG. 4 like the PC 1.

  FIG. 5A is a flowchart showing a power supply control process of the projector 4 executed by the PC 1. In the initial state of this process, it is assumed that the power source 4a of the projector 4 is off.

  First, the control unit 101 of the PC 1 executes authentication of the user on the object 8 side according to the user ID and password input from the input device 9, and determines whether or not to permit access to the PC 1 by the user on the object 8 side. Is determined (step S11).

  Next, the control unit 101 of the PC 1 determines whether or not the transmission / reception unit 102 has received a command to turn on the power source 4a of the projector 4 from the PC 2 (step S12).

  If NO in step S12, the process ends. On the other hand, in the case of YES in step S12, the control unit 101 of the PC 1 determines whether or not there is a user on the object 8 side permitted to access the PC 1 based on the determination in step S11 (step S11). S13).

  If NO in step S13, the process ends. On the other hand, if YES in step S13, the control unit 101 of the PC 1 turns on the power source 4a of the projector 4 (step S14), and ends this process.

  Thus, according to this power supply control process, when access to the PC 1 is permitted for the user on the object 8 side, the power supply 4a of the projector 4 is turned on, and the PC 2 which is a remote terminal is turned on. Since the annotation image is projected, leakage of information transmitted from the PC 2 can be avoided.

  FIG. 5B is a flowchart showing image projection processing of the projector 4 executed by the PC 1. In the initial state of this process, it is assumed that the power source 4a of the projector 4 is off, and only the process different from the process of FIG.

  In the case of NO in step S13, the control unit 101 of the PC 1 causes the projector 4 to project the annotation image received from the PC 2 onto the target object 8 so that the projector 4 receives a black image or randomly through the IF unit 104. The changing image is transmitted (step S16), and this process is terminated. In this case, the projector 4 projects a black image or a randomly changing image onto the object 8. Note that the information transmitted to the projector 4 in step S14 is not limited to a black image or a randomly changing image, but may be information other than the annotation image received from the PC 2.

  On the other hand, if YES in step S13, the control unit 101 of the PC 1 transmits the annotation image received from the PC 2 to the projector 4 via the IF unit 104 (step S15), and ends this process. In this case, the projector 4 projects the annotation image on the object 8.

  In this way, in this image projection process, when there is a user on the object 8 side permitted to access the PC 1, the annotation image transmitted from the PC 2 is projected, so that the information transmitted from the PC 2 Leakage can be avoided. Further, when there is no user on the object 8 side permitted to access the PC 1, a black image other than the annotation image transmitted from the PC 2 or a randomly changing image is projected, and thus transmitted from the PC 2. Leakage of annotation images can be avoided.

  FIG. 6 is a flowchart showing a first modification of the power control process of the projector 4 executed by the PC 1. In the initial state of this process, it is assumed that the power source 4a of the projector 4 is off.

  First, the control unit 101 of the PC 1 executes authentication of the user on the object 8 side according to the user ID and password input from the input device 9, and determines whether or not to permit access to the PC 1 by the user on the object 8 side. Is determined (step S21).

  Next, the control unit 101 of the PC 1 determines whether or not the transmission / reception unit 102 has received a command to turn on the power source 4a of the projector 4 and a user ID from the PC 2 (step S22).

  If NO in step S22, this process ends. On the other hand, in the case of YES in step S22, the control unit 101 of the PC 1 has received the user ID of the user on the object 8 side permitted to access the PC 1 from the PC 2 based on the database of FIG. It is determined whether or not it belongs to the same group as the ID (step S23).

  If NO in step S23, the process ends. On the other hand, if YES in step S23, the control unit 101 of the PC 1 turns on the power source 4a of the projector 4 (step S24), and ends this process.

  Thus, according to the power supply control process, when the user on the object 8 side belongs to the same group as the user on the PC 2 side, the power supply 4a of the projector 4 is turned on, and the power from the PC 2 is Since the annotation image is projected, leakage of the annotation image transmitted from the PC 2 can be avoided. Further, the access authority to the annotation image transmitted from the PC 2 of the user on the object 8 side can be managed in the database group column of FIG.

  FIG. 7 is a flowchart showing a second modification of the power control process of the projector 4 executed by the PC 1. In the initial state of this process, it is assumed that the power source 4a of the projector 4 is off.

  First, the control unit 101 of the PC 1 executes authentication of the user of the target object 8 according to the user ID and password input from the input device 9, and determines whether or not to allow the user of the target object 8 to access the PC 1. (Step S31).

  Next, the control unit 101 of the PC 1 determines whether or not the transmission / reception unit 102 has received a command to turn on the power source 4a of the projector 4 from the PC 2 (step S32).

  If NO in step S32, the process ends. On the other hand, if YES in step S32, the control unit 101 of the PC 1 determines whether or not there is a user on the side of the object 8 that is permitted to access the PC 1 based on the determination in step S31 (step S31). S33).

  If NO in step S33, the process ends. On the other hand, if YES in step S33, the control unit 101 of the PC 1 creates a list of users permitted to access the PC 1 and transmits the list to the PC 2 (step S34).

  The transmission / reception unit 202 of the PC 2 receives the created user list, and the display unit 205 displays a dialog box including the received user list, “OK” button, and “Cancel” button (step S35). FIG. 8 shows an example of a dialog box displayed on the display unit 205. When the “OK” button in the dialog box of FIG. 8 is pressed, the control unit 201 of the PC 2 transmits a command for maintaining a command to turn on the power supply 4 a of the projector 4 to the control unit 101 of the PC 1. On the other hand, when the “Cancel” button in the dialog box of FIG. 8 is pressed, the control unit 201 of the PC 2 transmits an instruction to stop the command to turn on the power supply 4 a of the projector 4 to the control unit 101 of the PC 1.

  The control unit 101 of the PC 1 determines whether or not an “OK” button in the dialog box is pressed and an instruction to maintain an instruction to turn on the power source 4 a of the projector 4 is received from the control unit 201 of the PC 2 ( Step S36).

  If YES in step S35, the control unit 101 of the PC 1 turns on the power source 4a of the projector 4 (step S37), and ends this process. On the other hand, in the case of NO in step S35, that is, when the control unit 101 of the PC1 receives a command for stopping the command to turn on the power supply 4a of the projector 4 from the control unit 201 of the PC2, this processing is ended.

  As described above, in this power supply control process, after the user on the PC 2 side confirms the list of users on the object 8 side, the power supply 4a of the projector 4 is turned on, and the annotation image from the PC 2 is projected. Therefore, leakage of the annotation image transmitted from the PC 2 can be avoided.

  9A and 9B are flowcharts showing a modification of the power supply control process of FIG. The same steps as those in FIG. 7 are denoted by the same reference numerals, and the description thereof is omitted.

  9A, in the case of YES in step S33, the control unit 101 of the PC 1 determines whether or not the cancel button has been pressed when the previous dialog box was displayed (step S51). Here, the control unit 101 of the PC 1 determines whether or not an instruction to stop the instruction to turn on the power supply 4 a of the projector 4 is received from the PC 2.

  If NO in step S51, the control unit 101 of the PC 1 does not do anything because the user list has already been approved by the user of the PC 2 and the power source 4a of the projector 4 is on, and the process returns to step S32. If YES in step S51, since the power source 4a of the projector 4 is still off, the process proceeds to step S34.

  In FIG. 9B, in the case of YES in step S33, the control unit 101 of the PC 1 is within a certain time since the cancel button was pressed when the previous dialog box was displayed, or the previous time It is determined whether or not there is a user who has newly logged in since the dialog box was displayed (step S52).

  If YES in step S52, the process proceeds to step S34 in order to display the user list on the display unit 205 of the PC 2 again. In the case of NO in step S52, there is no need to display the user list again on the display unit 205 of the PC 2, and the process returns to step S32 in order to keep the power source 4a of the projector 4 off.

  FIG. 10 is a flowchart showing a power control process executed by the PC 1 when all users who are permitted to access the PC 1 log off. In the initial state of this process, it is assumed that the power source 4a of the projector 4 is on.

  First, the control unit 101 of the PC 1 determines whether all users of the object 8 have logged off via the input device 9 (step S41). The control unit 101 of the PC 1 determines that all users on the object 8 side have logged off when there is no registered user in the user list.

  If NO in step S41, the determination process is repeated. On the other hand, in the case of YES in step S41, the control unit 101 of the PC 1 transmits information indicating that all the users on the object 8 side have logged off to the PC 2 (step S42). The transmission / reception unit 202 of the PC 2 receives information indicating that all users on the object 8 side have logged off, and the display unit 205 displays the information.

  Next, the control unit 101 of the PC 1 turns off the power source 4a of the projector 4 (step S43), and ends this process.

  In this way, in this power supply control process, when there is no user on the object 8 side permitted to access PC1, the power supply 4a of the projector 4 is turned off, so that an annotation image transmitted from the PC2 leaks.
