Abstract
A CC encoder outputs CC data for displaying a caption with a closed caption. A disparity information creation unit outputs disparity information related with each Window ID included in the CC data. The disparity information has added thereto instruction information instructing which of the left eye and the right eye is to be subjected to shifting on the basis of the disparity information. Also, the disparity information is either configured to be commonly used in individual frames during a display period of closed caption information or configured to be sequentially updated during the individual periods, and has added thereto identification information thereabout.
Claims14
A disparity information transmitting apparatus comprising:
- a disparity information output unit that outputs disparity information for giving disparity by shifting superimposition information to be superimposed on an image that is based on a left-eye image data and a right-eye image data;
- and
- a transmitting unit that transmits the disparity information output from the disparity information output unit,
- wherein the disparity information is disparity information that is sequentially updated in individual frames during a period of a predetermined number of frames during which the superimposition information is displayed.
A disparity information data receiving apparatus comprising:
- a receiving unit that receives disparity information for giving disparity by shifting superimposition information to be superimposed on an image that is based on a left-eye image data and a right-eye image data,
- the disparity information being disparity information that is sequentially updated in individual frames during a period of a predetermined number of frames during which the superimposition information is displayed;
- and
- an image data processing unit that gives disparity to the same superimposition information to be superimposed on a left-eye image and a right-eye image using the left-eye image data and the right-eye image data included in the stereo image data received by the receiving unit and the disparity information received by the receiving unit.
A disparity information data transmitting apparatus comprising:
- a disparity information output unit that outputs disparity information for giving disparity by shifting superimposition information to be superimposed on an image that is based on a left-eye image data and a right-eye image data;
- and
- a transmitting unit that transmits the disparity information output from the disparity information output unit,
- wherein the disparity information is disparity information that is commonly used in individual frames during a period of a predetermined number of frames during which the superimposition information is displayed, and
- wherein the disparity information has added thereto information indicating the disparity information that is commonly used in the individual frames or the disparity information that is sequentially updated in the individual frames.
A disparity information receiving apparatus comprising:
- a receiving unit that receives disparity information for giving disparity by shifting superimposition information to be superimposed on an image that is based on a left-eye image data and a right-eye image data,
- the disparity information being disparity information that is commonly used in individual frames during a period of a predetermined number of frames during which the superimposition information is displayed;
- and
- an image data processing unit that gives disparity to the same superimposition information to be superimposed on a left-eye image and a right-eye image using the left-eye image data and the right-eye image data included in the stereo image data received by the receiving unit and the disparity information received by the receiving unit.
A method for updating superimposition information for a stereoscopic image based on a left-eye image data and a right-eye image data, the method comprising the steps of:
- receiving disparity information for giving disparity by shifting superimposition information to be superimposed on a stereoscopic image that is based on the left-eye image data and the right-eye image data;
- detecting a predetermined number of frames based on frame term information;
- updating the disparity information for each frame during the predetermined number of frames;
- shifting the superimposing position based on the updated disparity information with regard to the left-eye image data and the right-eye image data.
A method for updating superimposition information for a stereoscopic image based on a left-eye image data and a right-eye image data, the method comprising the steps of:
- receiving disparity information for giving disparity by shifting superimposition information to be superimposed on a stereoscopic image that is based on the left-eye image data and the right-eye image data;
- detecting a number of divided regions of a display;
- wherein a common disparity information is used if the number of the divided regions is one, and individual disparity information corresponding to the divided regions is used if the number of divided regions is more than one.
