Abstract

A method (300) and apparatus (400) for three-dimensional television (3DTV) image adjustment includes loading (342, 344) default 2D-to-3D image setting values from a default settings memory to a user adjustment settings memory, annunciating (346) the default 2D-to-3D image setting values, receiving (361, 362) a 2D-to-3D image settings value adjustment, saving (370) the 2D-to-3D image settings value adjustment in the user adjustment settings memory, and applying (390) the 2D-to-3D image settings value adjustment to a 2D-to-3D converted image. These methods and apparatuses allow individual users to set 3DTV image settings to their personal preferences to compensate for brightness reductions caused by 3DTV glasses, depth perception sensitivities, and other image quality factors.

First claim

What is claimed is:

1. A method for three-dimensional image depth control, comprising:
converting a two-dimensional image (2D image) to a first three-dimensional image (3D image) based on a first 2D-to-3D depth value, wherein the first 2D-to-3D depth value represents an amount of perceived 3D depth provided in image frames converted from 2D video signals to 3D video signals;
causing a 2D-to-3D image test pattern to be presented on a display device;
causing the first 2D-to-3D depth value to be presented on the display device, wherein the first 2D-to-3D depth value is adjustable;
receiving one or more user instructions to set a second 2D-to-3D depth value that is different than the first 2D-to-3D depth value;
causing the 2D-to-3D image test pattern and the second 2D-to-3D depth value to be presented on the display device, wherein the 2D-to-3D image test pattern is updated based on the second 2D-to-3D depth value;
in response to receiving an acceptance of the second 2D-to-3D depth value, converting the 2D image to a second 3D image based on the second 2D-to-3D depth value;
causing the second 3D image to be presented;
receiving one or more user instructions to save the second 2D-to-3D depth value;
in response to the user instructions, saving the second 2D-to-3D depth value;
receiving a 2D video signal from a 2D video source;
converting the 2D video signal to a 3D video signal based on the second 2D-to-3D depth value; and
causing at least a portion of the 3D video signal to be presented.

2. The method of claim 1 , wherein the first 2D-to-3D depth value is a manufacturer default 3D depth value.

3. The method of claim 1 , further comprising receiving Extended Display Identification Data (EDID) information from a display device, wherein the EDID information indicates that the display device is a 3D display device.

4. The method of claim 3 , wherein the EDID information includes a default 3D depth value.

5. The method of claim 4 , further comprising detecting a connection to the 3D display device, wherein converting the 2D image to the first 3D image is performed in response to detecting the connection to the 3D display device.

6. A system for three-dimensional image depth control, comprising:
a processor that is programmed to:
convert a two-dimensional image (2D image) to a first three-dimensional image (3D image) based on a first 2D-to-3D depth value, wherein the first 2D-to-3D depth value represents an amount of perceived 3D depth provided in image frames converted from 2D video signals to 3D video signals;
cause a 2D-to-3D image test pattern to be presented on a display device;
cause the first 2D-to-3D depth value to be presented on the display device, wherein the first 2D-to-3D depth value is adjustable;
receive one or more user instructions to set a second 2D-to-3D depth value that is different than the first 2D-to-3D depth value;
cause the 2D-to-3D image test pattern and the second 2D-to-3D depth value to be presented on the display device, wherein the 2D-to-3D image test pattern is updated based on the second 2D-to-3D depth value;
in response to receiving an acceptance of the second 2D-to-3D depth value, convert the 2D image to a second 3D image based on the second 2D-to-3D depth value;
cause the second 3D image to be presented;
receive one or more user instructions to save the second 2D-to-3D depth value;
in response to the user instructions, save the second 2D-to-3D depth value;
receive a 2D video signal from a 2D video source;
convert the 2D video signal to a 3D video signal based on the second 2D-to-3D depth value; and
cause at least a portion of the 3D video signal to be presented.

7. The system of claim 6 , wherein the first 2D-to-3D depth value is a manufacturer default 3D depth value.

8. The system of claim 6 , wherein the processor is further programmed to receive Extended Display Identification Data (EDID) information from a display device, wherein the EDID information indicates that the display device is a 3D display device.

9. The system of claim 8 , wherein the EDID information includes a default 3D depth value.

10. The system of claim 9 , wherein the processor is further programmed to detect a connection to the 3D display device, wherein the processor converts the 2D image to the first 3D image is performed in response to detecting the connection to the 3D display device.

11. A non-transitory computer-readable medium containing computer executable instructions that, when executed by a processor, cause the processor to perform a method for three-dimensional image depth control, the method comprising:
converting a two-dimensional image (2D image) to a first three-dimensional image (3D image) based on a first 2D-to-3D depth value, wherein the first 2D-to-3D depth value represents an amount of perceived 3D depth provided in image frames converted from 2D video signals to 3D video signals;
