Abstract

The present invention provides a novel image output apparatus that includes an operation processing unit that processes an operation request from a user, a projecting unit that projects a display image from a video providing apparatus and UIs from the image projector, a determining unit that determines whether or not it is necessary to switch a source of a video signal by using a current input type and a source of a video signal with reference to a data table that associates an input type that indicates a type of a port from which an image to be projected is acquired with a source of a video signal that forms an image to be projected, and a controller that switches a source of a video signal and executes a process indicated by an operation request from a user if it is necessary to switch the source of a video signal.

First claim

What is claimed is:

1. An image output apparatus, comprising:
an operation processing unit to process an operation request;
a projecting unit to project a display image from a video providing apparatus and a UI from an image projector;
a data table storing unit to store a data table that associates an input type that indicates a type of a port from which an image to be projected is acquired with a source of a video signal that forms the image to be projected;
a determining unit to determine whether or not it is necessary to switch the source of the video signal by using a current input type and the source of the video signal;
a controller to switch the source of the video signal in case it is necessary to switch the source of the video signal and execute a process indicated by the operation request; and
a UI creating unit to create the UI,
wherein the controller determines whether or not it is possible to execute the process indicated by the operation request.

2. The image output apparatus according to claim 1 , wherein the determining unit determines that it is necessary to switch the source of the video signal in case the source of the video signal associated with the current input type is different from a current source of the video signal.

3. The image output apparatus according to claim 1 , wherein the controller stores the operation request in a storing unit in case the UI is currently being projected, and the controller determines whether or not the operation request is stored in the storing unit in case the controller receives the operation request to close the UI and executes the process indicated by the operation request in case the operation request is stored in the storing unit.

4. The image output apparatus according to claim 1 , wherein the controller stores setting information indicated by the UI and stops projecting the UI in case the controller receives the operation request and the UI is currently being projected, and the controller starts projecting the UI that reflects the setting information in case the setting information is stored in a storing unit after the controller executes the process indicated by the operation request.

5. The image output apparatus according to claim 1 , wherein the UI creating unit creates the UI indicating that it is impossible to execute the process indicated by the operation request in case it is impossible to execute the process indicated by the operation request, and the projecting unit projects the UI.

6. The image output apparatus according to claim 1 , wherein the UI includes a menu screen, a dialog box, a message window, an icon, and a help menu.

7. The image output apparatus according to claim 1 , wherein the operation request includes a request to change an aspect ratio of a projected image, a request to change lamp power to change an amount of light of a light source, a request to switch input to switch the video providing apparatus whose display image is to be projected, a request to change video mode, and a request to freeze the projected video image.

8. A method of outputting an image, comprising:
processing an operation request;
referencing a data table that associates an input type that indicates a type of a port from which an image to be projected is acquired with a source of a video signal that forms the image to be projected;
determining whether or not it is necessary to switch the source of the video signal by using a current input type and the source of the video signal;
switching the source of the video signal and executing a process indicated by the operation request in case it is necessary to switch the source of the video signal;
creating a UI; and
determining whether or not it is possible to execute the process indicated by the operation request.

9. A non-transitory computer-readable medium storing a program that, when executed by a computer, causes the computer to implement a method of outputting an image,
the method comprising:
processing an operation request;
referencing a data table that associates an input type that indicates a type of a port from which an image to be projected is acquired with a source of a video signal that forms the image to be projected;
determining whether or not it is necessary to switch the source of the video signal by using a current input type and the source of the video signal;
switching the source of the video signal and executing a process indicated by the operation request in case it is necessary to switch the source of the video signal;
creating a UI; and
determining whether or not it is possible to execute the process indicated by the operation request.

10. The image output apparatus according to claim 1 , wherein when it is determined that it is necessary to switch the source of the video signal, the controller sends a request to the UI creating unit to close the UI.

11. The image output apparatus according to claim 1 , wherein when it is determined that it is not possible to execute the process indicated by the operation request, the UI creating unit creates the UI indicating that it is not possible to execute the process indicated by the operation request.

12. The image output apparatus according to claim 1 , wherein when it is determined that it is necessary to switch the source of the video signal, the controller stores, in a storing unit, information that indicates that the UI was displayed and sends a request to the UI creating unit to close the UI.

13. The image output apparatus according to claim 12 , wherein the controller determines whether the UI was displayed.

14. The image output apparatus according to claim 13 , wherein when the controller determines that the UI was displayed, the controller sends another request to re-display the UI.

15. The image output apparatus of claim 14 , wherein the controller sends the another request to re-display the UI after sending the request to the UI creating unit to close the UI and after determining whether or not it is possible to execute the process indicated by the operation request.
