Abstract
A system and method for characterizing and adjusting an offset between displayed stereo image pairs allows for calibration of the stereo image content for each display environment. The stereo image content is typically authored assuming a particular display image size. When the stereo image content is displayed in a display environment that does not conform to the particular display image size the offset between displayed stereo image pairs is increased or decreased, resulting in a viewing experience that is different than intended. In some cases, the viewer may experience discomfort due to eye strain or eye fatigue. Adjusting the offset during the playback of the stereo image content may improve the viewer experience.
