<p>The invention concerns a method and a device for correcting distortion errors in a 3D content viewed by an observer on a screen. The method comprises the step of determining a rendered roundness factor (ITO of a pinhole model projected cylinder, estimating a rendered roundness factor table depending on the defined distance of the observer to the screen and the disparity values of objects of the image, determining for the observer a disparity transform function (TD) as a function of the estimated rendered roundness factor table and modifying the object disparity values using the disparity transform so that a perceived roundness factor of one is provided.</p> |
