A videotelephony system has an electronically controllable camera with a field of view, a visual token disposed within the field of view, and a camera controller. The camera controller is configured to detect the visual token and reconfigure the field of view relative to a detected position of the visual token.

System and method of videotelephony with detection of a visual token in the videotelephony image for electronic control of the field of view

A system and method for reducing distance-based distortion in a camera image of an object, where the distanced-based distortion is due to differences in distance from the camera to different parts of the object. In one approach, the distortion is reduced by estimating distances to different parts of the object and then generating a reprojected image of the object dependent upon the estimated distances and upon a virtual viewpoint that is more distant than the camera from the object. In a further approach, the image is warped such that points in the image match corresponding points in one or more stored templates. In a still further approach, if excessive distortion is present in the image, the camera zoom is increased and a magnified image is displayed, prompting a person to move farther from the camera thereby reducing the distortion.
