Claim Text:
1. A method for preparing subtitles for a stereoscopic presentation, comprising: processing a subtitle according to adjustment information; and compositing the processed subtitle into at least one stereoscopic image to produce at least one transformed stereoscopic image for stereoscopic presentation; comparing a footprint of the subtitle with a predetermined area of the at least one stereoscopic image; if any portion of the footprint is outside the predetermined area, determining the adjustment information for applying to the subtitle to produce an adjusted subtitle with an adjusted footprint lying completely inside the predetermined area; translating the subtitle to reduce the portion of the subtitle lying outside the predetermined area; if any portion of a footprint of the translated subtitle lies outside the predetermined area, applying a scale factor to the translated subtitle so that the scaled-down translated subtitle is completely inside the predetermined area; and adjusting the disparity of the translated, and optionally scaled-down, subtitle to be no greater than a minimum disparity of an object appearing within the adjusted footprint of the disparity-adjusted subtitle.
