Method to represent images for dissociative stereoscopic vision and related system
First Claim
Patent Images
1. A method to represent images for dissociative stereoscopic vision, comprising the following steps:
- a. fetching right and left images for stereoscopic vision;
b. suppressing even columns for one of the two images and odd columns for the other image;
c. fusing images derived from step b in order to create one single image made up of alternating columns belonging to the two images, so that the odd columns precisely belong to the first image and the even columns precisely belong to the second image;
d. splitting the image obtained step c into the two images obtained in step b;
e. filling a generic empty column i with data contained in column i+1, or as an alternative with data contained in column i−
1, for both images obtained in step d;
f. alternately showing the two images obtained in step e, on a video at high frequency, synchronously blanking right and left lenses worn by a patient, so that a right eye always sees a first image, and a left eye always sees a second image, or vice versa.

Abstract
The following is a method to represent images for dissociative stereoscopic vision, which allows, by means of some simple operations on stereoscopic images, to develop a device comprising a processing card and LCD shuttering goggles, which together with a computer equipped with a graphic card with LVDS output and any image display device, enable to perform visual acuity tests on patients.
