Abstract
A video conferencing system is provided that reduces the perspective of an image captured by a video conferencing camera. The perspective is reduced in an image by receiving a first image of a first field of view and receiving a second image of a second field of view. Moreover, the first image is equalized and the second image is equalized independently of the first image. Additionally, the first equalized image is stitched to the second equalized image to create a display image, which can be sent to a display another video conferencing endpoint.
