Three-dimensional video providing method and three-dimensional video display device

A stereoscopic image display device that generates a stereoscopic vision-use image by utilizing obtained data of a two-dimensional image and subordinate information thereof, comprising:

• a means for obtaining scale information and depth information from the subordinate information;
• a means for generating a parallax amount on the basis of the scale information and the depth information;
• and
• a means for generating a stereoscopic vision-use image on the basis of the parallax amount, wherein
• the means for generating the parallax amount determines a standard parallax amount on the basis of a depth value indicating an image displaying surface position included in the subordinate information.

A stereoscopic image display device that generates a stereoscopic vision-use image by utilizing obtained data of a two-dimensional image and subordinate information thereof, comprising:

• a means for obtaining depth information and function specifying information from the subordinate information;
• a means for storing a plurality of functions for allowing values corresponding to distances indicated by values of the depth information to have non-equal differences contrary to the values of the depth information having a uniform difference;
• a means for selecting a function on the basis of the function specifying information;
• a means for generating a parallax amount on the basis of the selected function and the depth information;
• and
• a means for generating a stereoscopic vision-use image on the basis of the parallax amount, wherein
• the means for generating the parallax amount determines a standard parallax amount on the basis of a depth value indicating an image displaying surface position included in the subordinate information.

A stereoscopic image display device that generates a stereoscopic vision-use image by utilizing obtained data of a two-dimensional image and subordinate information thereof, comprising:

• a means for obtaining depth information and table specifying information from the subordinate information;
• a means for storing a plurality of tables for allowing values corresponding to distances indicated by values of the depth information to have non-equal differences contrary to the values of the depth information having a uniform difference;
• a means for selecting a table on the basis of the table specifying information;
• a means for generating a parallax amount on the basis of the selected table and the depth information;
• and
• a means for generating a stereoscopic vision-use image by utilizing the parallax amount, wherein
• the means for generating the parallax amount determines a standard parallax amount on the basis of a depth value indicating an image displaying surface position included in the subordinate information.
