Method for displaying stereoscopic images and image display apparatus thereof

A method for displaying stereoscopic images, comprising:

• receiving, by a receiver, the stereoscopic image having a first depth level value and produced based on a left eye image and a right eye image, the stereoscopic image including at least first and second objects;
• adjusting, by a controller, the depth levels based on the first depth level value to pre-set depth level values by the user input;
• and
• displaying, by a display, the stereoscopic image having the adjusted depth level value on a screen,
• wherein the pre-set depth level values are set to be corresponded to at least one of a forward 3D depth adjustment mode, a backward 3D depth adjustment mode and a bi-directional 3D depth adjustment mode,
• wherein in the forward 3D depth adjustment mode, both the first and second objects included in the stereoscopic image increase from the first depth level value to a second depth level value such that both the first and second objects have a perspective in a direction that exits the outside of the screen,
• wherein in the backward 3D depth adjustment mode, both the first and second objects included in the stereoscopic image decreases from the first depth level value to a third depth level value such that both the first and second objects have a perspective in a direction that enters the inside of the screen, and
• wherein in the bi-directional 3D depth adjustment mode, the first object included in the stereoscopic image increase from the first depth level value to a fourth depth level value such that the first object has a perspective in a direction that exits the outside of the screen and, at the same time, the second object included in the stereoscopic image decreases from the first depth level value to a fifth depth level value such that the second objects has a perspective in a direction that enters the inside of the screen.

An image display apparatus, comprising:

• a receiver that receives the stereoscopic image having a first depth level value and produced based on a left eye image and a right eye image, the stereoscopic image including at least first and second objects;
• a controller that produces a depth map having a first depth level value based on the left eye image and the right eye image, adjusts the first depth level value representing a perspective of the first and second objects included in the stereoscopic images according to any one selected by the user of a plurality of depth level adjustment modes;
• a storage device that stores the adjusted first depth level value;
• and
• a display that displays the stereoscopic images having the adjusted first depth level value on a screen,
• wherein the plurality of depth level adjustment modes includes a forward 3D depth adjustment mode, a backward 3D depth adjustment mode and a bi-directional 3D depth adjustment mode,
• wherein in the forward 3D depth adjustment mode, both the first and second objects increase from the first depth level value to a second depth level value such that both the first and second objects have a perspective in a direction that exits the outside of the screen,
• wherein in the backward 3D depth adjustment mode both the first and second objects decreases from the first depth level value to a third depth level value such that both the first and second objects have a perspective in a direction that enters the inside of the screen, and
• wherein in the bi-directional 3D depth adjustment mode, the first object increase from the first depth level value to a fourth depth level value such that the first object has a perspective in a direction that exits the outside of the screen and, at the same time, the second object decreases from the first depth level value to a fifth depth level value such that the second objects has a perspective in a direction that enters the inside of the screen.
