Abstract

System and method for adjusting the position of a displayed image of a person. The system comprises a control unit that receives a sequence of images and processes the received images to determine whether the person is positioned at the border of the received images to be displayed. If so positioned, the control unit generates control signals to control the position of an optical device providing the sequence of images so that the person is positioned entirely within the image.

Claims

1. A system for adjusting the position of a displayed image of a person, the system comprising a control unit that receives a sequence of images, the control unit processing the received images to determine whether the person is positioned at the border of the received images to be displayed and, when it is determined that the person is positioned at the border of the received images to be displayed, generating control signals to control the position of an optical device providing the sequence of images so that the person is positioned entirely within the image.

2. The system as in claim 1, wherein the control unit determines that the person is positioned at the border of the received images by identifying a moving object in the sequence of image as the person and tracking the person'"'"'s movement in the sequence of images to the border of the image.

3. The system as in claim 2, wherein the moving object is identified as the person by processing the data for the object using an RBF network.

4. The system as in claim 2, wherein tracking the person'"'"'s movement in the sequence of images includes identifying at least one feature of the person in the image and using the at least one feature to track the person in the image.

5. The system as in claim 4, wherein the at least one feature is at least one of a color and a texture of at least one region of the person in the image.

6. The system as in claim 2, wherein the control unit receives two or more sequences of images from two or more respective optical devices, the optical devices positioned so that regions of the respective two or more sequences of images overlap, the two or more sequences of images being separately displayed.

7. The system as in claim 6, wherein, for each of the two or more sequences of images, the control unit processes received images of the sequence to determine whether the person is positioned at a border of the received images.

8. The system as in claim 7, wherein, for at least one of the two or more sequences of images where the control unit determines that the person is positioned at the border of the received images, the control unit generates control signals to control the position of the optical device for the respective sequence of images so that the entire image of the person is captured.

9. The system as in claim 8, wherein the control unit generates control signals so that the optical device is moved to position the person completely within the image.

10. The system as in claim 7, wherein, for each of the two or more sequences of images, the determination by the control unit of whether the person is positioned at the border of received images of the sequence comprises identifying moving objects in the sequence of images, determining whether the moving objects are persons and tracking moving objects determined to be persons within the sequence of images.

11. The system as in claim 10, wherein the tracking of moving objects determined to be persons within each of the sequence of images further comprises identifying which persons are the same person in two or more of the sequences of images.

12. The system as in claim 11, wherein the control unit determines that the person is positioned at the border of the received images for at least one of the sequence of images by identifying the person as the same person in two or more sequences of images and tracking the person to a position at the border of at least one of the sequences of images.

13. A method of adjusting the position of a displayed image of a person, the method comprising the steps of receiving a sequence of images, determining whether the person is positioned at the border of the received images to be displayed and adjusting the position of an optical device providing the sequence of images so that the person is positioned entirely within the image.

14. The method of claim 13, wherein the step of determining whether the person is positioned at the border of the received images to be displayed comprises the step of identifying the person in the received images.

15. The method of claim 14, wherein the step of determining whether the person is positioned at the border of the received images to be displayed also comprises the step of tracking the person in the received images.

16. A method of adjusting the position of a displayed image of a person, the method comprising the steps of receiving two or more sequence of images, determining whether the person is visible in whole or in part in each of the received sequences of images to be displayed and, where the person is determined to be partially visible in one or more of the received sequences of images to be displayed, adjusting at least one optical device providing the corresponding one of the one or more received sequences of images so that the person is positioned entirely within the received images.
