A method for producing a magnified three dimensional (3D) image of an object having a parallax modified according to the magnification including the procedures of acquiring a first image of the object by a first camera and a second image of the object by a second camera, determining a magnification parameter, generating a first magnified image and a second magnified image by respectively magnifying a portion of the first image containing the object and a portion of the second image containing the object according to the magnification parameter, modifying a geometry of the first magnified image and of the second magnified image as a function of the magnification parameter, thereby producing a first modified image and a second modified image, and displaying the magnified 3D image to a user by displaying the first modified image and the second modified image.
