Abstract

According to some aspect, an image display apparatus may include a communication section receiving a plurality of remote operation signals corresponding to remote operations of a plurality of input apparatuses, and a combination section combining a first image based on the plurality of individual remote operation signals received by the communication section and a second image supplied from other apparatus into a third image, and outputting the third image.

First claim

What is claimed is:

1. A projection apparatus comprising:
a communication unit configured to receive a remote operation signal corresponding to a remote operation of an input apparatus;
an execution unit configured to:
identify a first remote operation signal received by the communication unit as having been produced by a first input apparatus of a plurality of input apparatuses;
generate a first image based at least in part on the first remote operation signal; and
produce a third image by overlaying the first image onto a second image received from an image output apparatus different from the plurality of input apparatuses, the second image being data describing a two-dimensional image; and

a projector configured to optically project the third image onto a screen.

2. The projection apparatus of claim 1 , wherein the image output apparatus is a personal computer.

3. The projection apparatus of claim 1 , wherein the execution unit is configured to receive the second image via a High Definition Multimedia Interface (HDMI) connection.

4. The projection apparatus of claim 1 , wherein the execution unit is configured to generate, as part of the first image, at least a first pointer icon associated with the first remote operation signal of the plurality of remote operation signals.

5. The projection apparatus of claim 4 , wherein the first remote operation signal is associated with a first user of a plurality of users, and wherein the execution unit is further configured to select a color and a shape for the first pointer icon based on data associated with the first user.

6. The projection apparatus of claim 1 , wherein the execution unit is further configured to:
obtain access-right data for at least a first user, the first user associated with the first input apparatus of the plurality of input apparatuses; and
generate the first image based at least in part on the obtained access rights data for the first user.

7. The projection apparatus of claim 1 , wherein the communication unit is further configured to receive access-right data from the plurality of input apparatuses.

8. An image display system comprising:
at least one input apparatus configured to wirelessly transmit operation signals, the operation signals indicative of user operations performed with the at least one input apparatus;
and
a projector, comprising:
a communication unit configured to wirelessly receive an operation signal from the at least one input apparatus;
an execution unit configured to:
identify a first operation signal received by the communication unit as having been produced by a first input apparatus of the at least one input apparatus;
generate a first image based at least in part on the first operation signal and
produce a third image by overlaying the first image onto a second image received from a video source device different from the at least one input apparatus, the second image being data describing a two-dimensional image; and

a display unit configured to optically project the third image through at least one lens onto a screen.

9. The image display system of claim 8 , wherein the video source device is a personal computer.

10. The image display system of claim 8 , wherein the projector is configured to be connected to the video source device via a High Definition Multimedia Interface (HDMI) connection.

11. The image display system of claim 8 , wherein the execution unit is configured to generate, as part of the second image, a pointer icon associated with the first operation signal received from a first input apparatus of the at least one input apparatus.

12. The image display system of claim 11 , wherein the first operation signal is associated with a first user of a plurality of users, and wherein the execution unit is further configured to select a color and a shape for the first pointer icon based on data associated with the first user.

13. The projection apparatus of claim 1 , wherein the execution unit is configured to generate the first image by:
selecting a first color from a plurality of colors based on said identification of the first remote operation signal as having been produced by the first input apparatus; and
generating image data of the first color based on the first remote operation signal.
