Method and system for disparity adjustment during stereoscopic zoom

摘要

A method for zooming a stereoscopic image appearing on an electronic display of a stereoscopic image displaying device. The stereoscopic image has horizontal disparity and is generated by an electronic processor from stereoscopic image data stored in a memory as a left-eye image pixel map and a right-eye image pixel map. The horizontal disparity of the stereoscopic image data is adjusted to produce disparity-adjusted, scaled stereoscopic image data based on a heuristic defining a relationship between a user zoom request, a predetermined stereoscopic factor and a relative horizontal shift between the left-eye image pixel map and the right-eye image pixel map. A zoomed stereoscopic image corresponding to the disparity-adjusted, scaled stereoscopic image data is displayed.

1. A method for zooming a stereoscopic image appearing on an electronic display of a stereoscopic image displaying device in response to receiving a user zoom request comprising a zoom magnitude, the stereoscopic image comprising a left-eye image and a right-eye image having relative horizontal disparity and being generated by a an electronic processor from stereoscopic image data stored in a memory as a left-eye image pixel map comprising left-eye pixels and a right-eye image pixel map comprising right-eye pixels, the method comprising the steps of:
scaling the stereoscopic image data to produce scaled stereoscopic image data in response to the user zoom request; adjusting the horizontal disparity of the scaled stereoscopic image data to produce disparity-adjusted, scaled stereoscopic image data based on a heuristic defining a relationship between the user zoom request, a predetermined stereoscopic factor Fs within a range of about 35 to 45 and a relative horizontal shift between the left-eye pixels in the left-eye image pixel map and the right-eye pixels in the right-eye image pixel map; and displaying a zoomed stereoscopic image on the display corresponding to the disparity-adjusted, scaled stereoscopic image data.
