Abstract

A projector that performs projection in cooperation with another projector, the projector including a determining unit configured to determine an operation state of the other projector and a control unit configured to control the projector to shift to, when the determining unit determines that the operation state of the other projector is not a normal operation state, a limited operation mode for limiting execution of at least a part of functions.

Claims

1. A projector that performs projection in cooperation with another projector, the projector comprising:

a determining unit configured to determine an operation state of the other projector; and

a control unit configured to control the projector to shift to, when the determining unit determines that the operation state of the other projector is not a normal operation state, a limited operation mode for limiting execution of at least a part of functions.

2. The projector according to claim 1, wherein the control unit limits, in the limited operation mode, execution of a function that requires a projection state of the projector to be consistent with a projection state of the other projector.

3. The projector according to claim 1, further comprising an operation detecting unit configured to detect operation by a remote controller, wherein

the control unit controls the projector to shifts to a sub-operation mode when the determining unit determines that the operation state of the other projector is the normal operation state, and

in the sub-operation mode, even if the operation detecting unit detects the operation by the remote controller, the projector does not independently execute a function according to the operation.

4. The projector according to claim 3, wherein the control unit changes, in the limited operation mode, the function to be executed according to the operation by the remote controller to a function different from a function in the sub-operation mode.

5. The projector according to claim 3, wherein, in the limited operation mode, the control unit controls the projector to shifts to a stop state when the operation detecting unit detects predetermined operation of the remote controller other than power supply operation.

6. The projector according to claim 5, further comprising a notifying unit configured to notify the shift to the stop state when the operation detecting unit detects the predetermined operation of the remote controller.

7. The projector according to claim 1, wherein the control unit shifts to a stop state when, at start of projection, the determining unit determines that the operation state of the other projector is not the normal operation state.

8. A control method for a projector for controlling the projector to execute projection in cooperation with another projector, the control method comprising:

determining an operation state of the other projector; and

shifting to, when it is determined that the operation state of the other projector is not a normal operation state, a limited operation mode for limiting execution of at least a part of functions.

9. The control method according to claim 8, wherein, in the limited operation mode, execution of a function that requires a projection state of the projector to be consistent with a projection state of the other projector is limited.

10. The control method according to claim 8, further comprising:

detecting operation by a remote controller;

shifting to a sub-operation mode when it is determined that the operation state of the other projector is the normal operation state; and

causing, in the sub-operation mode, the projector not to independently execute a function according to the operation even if the operation is detected by the remote controller.

11. The control method according to claim 10, further comprising:

changing, in the limited operation mode, the function to be executed according to the operation by the remote controller to a function different from a function in the sub-operation mode.

12. The method according to claim 10, further comprising

shifting, in the limited operation mode, to a stop state when predetermined operation of the remote controller other than power supply operation is detected.

13. The method according to claim 12, further comprising

notifying the shift to the stop state when the predetermined operation of the remote controller is detected.

14. The method according to claim 8, further comprising

shifting to a stop state when, at start of projection, it is determined that the operation state of the other projector is not the normal operation state.
