Method of playing back image on display device and display device

A method of playing back an image on a display device, the method comprising:

• obtaining a stereo image corresponding to both eyes of a user including a left eye and a right eye;
• obtaining positions of the eyes;
• determining warping transform information corresponding to the positions of the eyes based on a database (DB) that is provided in advance based on a curvature of an display plane of the display device;
• warping the stereo image by applying the warping transform information to the stereo image;
• determining pixel values of a display panel included in the display device from the warped stereo image by performing light field rendering based on the positions of the eyes;
• and
• reproducing the determined pixel values on the display panel.

A display device for playing back an image, the display device comprising:

• a communication interface configured to obtain a stereo image corresponding to both eyes of a user including a left eye and a right eye, and positions of the eyes;
• and
• a processor configured to
• determine warping transform information corresponding to the positions of the eyes based on a database (DB) that is provided in advance based on a curvature of an display plane of the display device,
• warp the stereo image by applying the warping transform information to the stereo image,
• determine pixel values of a display panel included in the display device from the warped stereo image by performing light field rendering based on the positions of the eyes, and
• reproduce the determined pixel values on the display panel.

A method for displaying an image on a device, the method comprising:

• mapping a position of a display device to a world coordinate system;
• obtaining three-dimensional (3D) positions of eyes of a user based on the world coordinate system;
• determining warping meshes corresponding to the 3D positions of the eyes from a database (DB) containing a plurality of meshes corresponding to different positions along a curvature of an display plane of the device;
• applying the warping meshes to an input image;
• and
• outputting the warped image.
