Abstract

The present invention relates to a method for controlling an image display device including a flexible display unit, comprising the steps of: obtaining a multi-view image signal including camera position information; obtaining information on the shape of the flexible display unit on the basis of the obtained multi-view image signal; and modifying the shape of the flexible display unit on the basis of the obtained shape information.

First claim

The invention claimed is:

1. A method for controlling an image display device having a flexible display module, the method comprising:
receiving a multi-view image signal for one object captured by a plurality of stereoscopic image cameras;
acquiring alignment information regarding a position of the plurality of stereoscopic image cameras from the received multi-view image signal;
generating curvature information related to a curved shape of the flexible display module corresponding to the alignment information regarding the position of the plurality of stereoscopic image cameras; and
outputting a shape change guide including a shape change position and a shape change angle of the flexible display module to the flexible display module based on the generated curvature information,
wherein the shape change position refers to a position at which the flexible display module should be folded and the shape change angle refers to an angle which should be formed between a folded region and a non-folded region when the flexible display module is folded.

2. The method of claim 1 , wherein the multi-view image signal comprises stereoscopic image data.

3. The method of claim 1 , wherein receiving the multi-view image signal comprises:
calculating depth information between two image signals which are included in the multi-view image signal; and
generating an image between the two image signals using interpolation based on the calculated depth information.

4. The method of claim 1 , further comprising:
changing, by a former shape of the image display device, a curvature of the curved shape of the flexible display module based on the output shape change guide,
wherein changing the curvature comprises applying heat to a shape-former based on the output shape change guide.

5. The method of claim 4 , wherein changing the curvature comprises operating the shape-former based on the output shape change guide.

6. An image display device comprising:
a flexible display module;
a receiver configured to receive a multi-view image signal for one object captured by a plurality of stereoscopic image cameras; a controller configured to:
acquire alignment information regarding a position of the plurality of stereoscopic image cameras from the received multi-view image signal,
generate curvature information related to a curved shape of the flexible display module corresponding to the alignment information regarding the position of the plurality of stereoscopic image cameras, and
output a shape change guide including a shape change position and a shape change angle of the flexible display module to the flexible display module based on the generated curvature information,

wherein the shape change position refers to a position at which the flexible display module should be folded and the shape change angle refers to an angle which should be formed between a folded region and a non-folded region when the flexible display module is folded.

7. The image display device of claim 6 , further comprising:
a shape-former configured to change a curvature of the curved shape of the flexible display module based on the output shape change guide.
