METHOD AND SYSTEM FOR AUTOMATIC CAMERA CONTROL
First Claim
1. A method for automatically determining an orientation and zoom of an image pickup device associated with a video conferencing system, wherein said method comprises the steps of:
- generating, at said image pickup device, an image signal representative of an image framed by said image pickup device;
processing the image signal to identify objects in said image;
steering the image pickup device to an initial orientation;
determining a location of all the identified objects relative to a reference point and determining respective sizes of the identified objects;
defining an area of interest in said image, wherein said area of interest includes all the identified objects; and
steering the image pickup device to frame said defined area of interest including all the identified objects where a center of the frame substantially coincides with a center formed by a group of all the identified objects.

Abstract
A method for automatically determining an orientation and zoom of an image pickup device associated with a video conferencing system, wherein the method includes the steps of: generating, at the image pickup device, an image signal representative of an image framed by the image pickup device; processing the image signal to identify objects plural users of the video conferencing system in the image; steering the image pickup device to an initial orientation; determining a location of all the identified objects relative to a reference point and determining respective sizes of the identified objects; defining an area of interest in the image, wherein the area of interest includes all the identified objects; and steering the image pickup device to frame the defined area of interest including all the identified objects where a center of the frame substantially coincides with a center of all the identified objects.

14. A system for automatically determining an orientation and zoom of an image pickup device associated with a video conferencing system, wherein said system comprises:
-
an image pickup device configured to generate image signals representative of an image framed by said image pickup device; a video detection unit configured to process the image signal to identify objects in said image, to determine a location of all the identified objects relative to a reference point, and to determine respective sizes of the identified objects; an image processing unit configured to define an area of interest in said image, wherein said area of interest includes all the identified objects; and a control unit configured to, on an occurrence of a predefined event, steer the image pickup device to an initial orientation, to receive camera coordinates from said image processing unit corresponding to said area of interest, to steer the image pickup device to frame said area of interest including all the identified objects where a center of the frame substantially coincides with a center formed by a group of all the identified objects. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A computer readable storage medium encoded with instruction, which when executed by a computer, causes the computer to implement a method for automatically determining an orientation and zoom of an image pickup device associated with a video conferencing system, wherein said method comprises the steps of:
-
generating, at said image pickup device, an image signal representative of an image framed by said image pickup device; processing the image signal to identify objects plural users of the video conferencing system in said image; steering the image pickup device to an initial orientation; determining a location of all the identified objects relative to a reference point and determining respective sizes of the identified objects; defining an area of interest in said image, wherein said area of interest includes all the identified objects; and steering the image pickup device to frame said defined area of interest including all the identified objects where a center of the frame substantially coincides with a center formed by a group of all the identified objects.
