Abstract

Methods, devices and systems are provided which produce a synthesized stereoscopic image of a source image by forming at least two images from a source image where at least one image has been modified relative to the source image such that the images have a different spacial appearance than each other. A wide variety of modifications may be made to the source object in order to form modified stereo images. These modifications may involve modifying one or more images relative to the source image. For example, at least one image may be magnified, reduced, or rotated in the X, Y and/or Z plane relative to the source image. Alternatively or in addition, the position of one or more elements of one of the images may also be changed relative to the source image. Alternatively or in addition, at least one of the images may be transformed relative to the source image using a function which alters the position of elements of the image along the X or Y axis relative to the source image. In one variation, the function is a distorting algorithm, for example an elliptical or aspheric distorting algorithm which is not dependent on the depth information of the source image.
