ABSTRACT:
A method and system for producing normalized images of conference participants so that the participants appear to be approximately the same size when the images are displayed is provided. The normalizing system normalizes the size of images based on constraints relating to the distance of participants from the location of the camera. To normalize the image of a participant, the system zooms the camera to account for the distance of the participant from the camera.
