1. A method for image processing in a videoconference, comprising:
- receiving a video frame;
coding a first portion of the video frame at a different quality than a second portion of the video frame, based on an optical property wherein the optical property is an optical distortion property of a panoramic video camera, predetermined by measuring distortion of a known video frame; and
displaying the video frame.

10. A multi-point videoconferencing system comprised of:
-
a first point of the multi-point videoconferencing system comprised of a first camera, a first video display, and one or more first positions, wherein a video frame captured at the first point is a panoramic image; a second point of the multi-point videoconferencing system comprised of a second camera, a second video display, one or more second positions; and a processor operably connected with the first camera, wherein the processor is configured to code a first portion of the video frame at a different quality than a second portion of the video frame, based on an optical property;
wherein the optical property is an optical distortion property of the first video camera, predetermined by at least one of, measuring distortion of a known video frame at different camera focal lengths, measuring distortion of a known video frame by determining pixel resolution for a line or a group of lines, or measuring distortion of a known video frame by determining correlation coefficients between adjacent pixels. - View Dependent Claims (11, 12, 13, 14, 15)

16. A computer readable storage medium having computer executable instructions embodied thereon for image processing, comprising:
-
receiving a video frame from a video camera in a video conference; predetermining an optical distortion property of the video camera by at least one of, measuring distortion of a known video frame at different camera focal lengths, measuring distortion of a known video frame by determining pixel resolution for a line or a group of lines, or measuring distortion of a known video frame by determining correlation coefficients between adjacent pixels; coding a first portion of the video frame at a different quality than a second portion of the video frame, based on the optical distortion property; and displaying the video frame. - View Dependent Claims (17)
