A method and system for preparing subtitles for use in a stereoscopic presentation are described. The method allows a subtitle to be displayed without being truncated or masked by comparing the subtitle's initial footprint with an image display area. If any portion of the initial footprint lies outside the image display area, the subtitle is adjusted according to adjustment information, which includes at least one of: a scale factor, a translation amount and a disparity change, so that the adjusted subtitle lies completely within the image display area. Furthermore, the disparity of the subtitle can be adjusted by taking into account the disparities of one or more objects in an underlying image to be displayed with the subtitle.
