Abstract

An exemplary image control method is adapted for an image control system including a document camera and a first user device. In the image control method, the document camera generates a first image and provides the first image to the first user device for display. The first user device then produces a control information in response to an operation performed on the first image displayed on the first user device. After that, the first image is transformed into a second image. Finally, the first user device displays the second image.

Claims

1. An image control method adapted for a document camera and a first user device, the image control method comprising:

generating a first image by the document camera and providing the first image from the document camera to the first user device for display;

producing a control information in response to an operation performed on the first image displayed on the first user device;

transforming the first image into a second image according to the control information; and

displaying the second image on the first user device.

2. The image control method according to claim 1, further comprising:

receiving the first image and the control information separately by a second user device; and

displaying the second image on the second user device.

3. The image control method according to claim 2, further comprising:

providing a first operation request and a second operation request respectively by the first user device and the second user device; and

determining the first user device to be assigned with a master rights according to the first and second operation requests.

4. The image control method according to claim 1, further comprising:

receiving and displaying the second image by a second user device.

5. The image control method according to claim 4, further comprising:

providing a first operation request and a second operation request respectively by the first user device and the second user device; and

determining the first user device to be assigned with a master rights according to the first and second operation requests.

6. The image control method according to claim 5, wherein the step of determining the first user device to be assigned with a master rights according to the first and second operation requests is performed by a servo process, and the server process is executed by the document camera, the first user device, the second user device or a servo device.

7. The image control method according to claim 1, wherein the step of producing a control information in response to an operation performed on the first image displayed on the first user device comprises:

providing a user interface;

performing an edit operation on the first image through the user interface; and

transforming a content of the edit operation into the control information.

8. The image control method according to claim 1, wherein the step of transforming the first image into a second image according to the control information is performed by the document camera or the first user device.

9. An image control system comprising:

a document camera, for generating and providing a first image; and

a first user device, signally connected with the document camera and for receiving and displaying the first image and then producing a control information in response to an operation performed on the displayed first image, wherein the control information is transmitted to the document camera from the first user device, the first user device further transforms the first image into a second image according to the control information and then displays the second image.

10. The image control system according to claim 9, further comprising:

a second user device, signally connected with both the document camera and the first user device and for receiving and displaying the second image.

11. The image control system according to claim 10, wherein the first user device and the second user device respectively provide a first operation request and a second operation request, and the first and second operation requests are used to determine the first user device to be given a master rights by a servo process.

12. The image control system according to claim 9, further comprising:

a second user device, signally connected with both the document camera and the first user device and for transforming the first image into the second image according to the control information and displaying the second image after receiving the first image and the control information.

13. The image control system according to claim 12, wherein the first user device and the second user device respectively provide a first operation request and a second operation request, and the first and second operation requests are used to determine the first user device to be given a master rights by a servo process.
