In stereoscopic media, subtitles can have x, y, and z components to their placement. The x and y components correspond to the lateral and vertical axis that are associated with standard, two-dimensional media. However, the z component, or depth, corresponds to the axis normal to the x and y axis. This depth component is not present in traditional two dimensional media. The depth position of subtitles in stereographic media can significantly affect the readability of such subtitles. For example, subtitles whose depth is too deep may be buried by video or images that are perceived as extending closer to a user. Thus, it is desirable to provide a system for determining and setting appropriate depths for subtitles in stereoscopic media.

 

 

在立体媒体中，字幕对于其位置可具有x、y以及z分量。x和y分量对应于与标准二维媒体相关的横轴和纵轴。而z分量或深度对应于与x轴和y轴垂直的轴。在传统的二维媒体中不存在深度分量。立体媒体中字幕的深度位置会极大地影响这种字幕的可读性。例如，深度太深的字幕可能被感知为更靠近用户的视频或图像埋没。因此，期望提供这样的系统，用于确定和适当地设置立体媒体中字幕的深度。
