Dual-axis image equalization in video conferencing

摘要

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.

主权项

1. A video conferencing system comprising:
a first camera including a lens; a second camera including a lens; a processor coupled to the first camera and the second camera; and an output coupled to the processor; wherein:
the first camera is positioned at a determined angle to create a first image of a first scene within a first field of view;the second camera is positioned at a determined angle to create a second image of a second scene within a second field of view; andthe processor:
receives the first image;receives the second image;equalizes the first image, wherein the processor equalizes with a dual-axis warping function;equalizes the second image independently of the first image, wherein the processor equalizes with the dual-axis warping function used to equalize the first image;stitches the first equalized image to the second equalized image to create an display image; andsends the display image to the output.
