1. A method for reconstructing at least one pair of images of a stereoscopic video stream starting from a composite image, said composite image comprising information about a right image, a left image, and a further region, the method comprising the steps of: generating a first image of said right and left images by copying a single group of contiguous pixels from a first region of said composite image, generating a second image of said right and left images by copying other groups of contiguous pixels from a number of distinct regions of said composite image, said number of distinct regions being different from said first region; generating at least one depth or disparity map by copying at least one group of contiguous pixels from said further region of said composite image, different from said first region and from said number of distinct regions, said further region having horizontal and vertical dimensions which are half the dimensions of said right and left images, said at least one depth or disparity map having horizontal and vertical resolution equal to half the resolution of said right and left images, reading said at least one depth or disparity map, said depth or disparity map being map associated with one of said right and left images, and using said at least one depth or disparity map and at least one of said right and left images for reconstructing an intermediate image between said left and right images.
