Accordingly, by adjusting the display intervals of the left eye image and the right eye image, the depth of the 3D image or the 3D object composed of the left eye image and the right eye image can be adjusted.
9 to 11 are views referred to explain the image display apparatus according to the embodiment of the present invention.
Currently, some video display devices include 3D auto-detect function of contents. However, if 3D function such as 3D World or HDMI in is available, auto-detect only in 3D mode, detect function is turned on. The reason I do not always turn on 3D auto detection is because of the high detection error rate.
For example, if there is a scene in which a window is arranged symmetrically in a 2D image, it can be recognized as a 3D image and forced to change to a 3D mode. If the 2D image is forcibly changed to the 3D image, the user can not see the proper image.
In recent years, a video display device has been connected to a network to freely use the Internet, and a smart function for installing and using various applications has been supported. In addition, there may be applications that support 3D among various applications.
For example, by creating Side-By-Side and Top-Bottom screens in applications such as wallpaper, home launchers, and games, You can see it as a solid. For such applications, it is possible to turn on the 3D auto detection function and to provide the convenience to the user if the side-by-side, top-bottom, etc. screens can be automatically converted to the 3D mode.
An
If you turn on the 3D auto detection function for all applications, you can force 3D conversion even if it is not 3D as described above.
In this case, the user feels very uncomfortable, and the 3D auto detection function is turned off and the image display device is used.
Also, in this case, the user has the inconvenience of turning on the 3D mode every time the same 3D supporting application is executed.
However, the present invention can set and store various 3D environment settings such as a 3D auto sensing function for each application, or set and store each 3D environment setting for each predetermined application.
The 3D setting input may be an input for setting at least one of whether to automatically convert to a 3D mode (whether or not a 3D automatic sensing function is used), a 3D format such as a side-by-side, a top-bottom, .
In addition, the 3D setting input may be an input for setting to switch to the 3D mode automatically when the set application is executed or in response to the predetermined activity of the set application. In this case, the 3D setting input may further include an input for setting a format of the 3D image.
Accordingly, it is possible to provide the user with the convenience of automatically converting a stereoscopic 3D image from a specific screen of a predetermined application or executing a predetermined application.
9 to 11 show various examples of the 3D setting screen.
The
According to an embodiment of the present invention, a user can manage an application to be turned on in 3D automatic detection function.
Referring to the
On the other hand, an
On the other hand, if the user manually converts the 3D mode during execution of the
On the other hand, in the case of the application set as the 3D automatic detection function item, it is possible to set not to switch to the 3D mode unconditionally at the time of executing the application, but to turn on the 3D automatic detection function from the specific scene and switch to the 3D mode.
For example, in the case of using an Android OS, each scene may be configured as an activity, and the activity may correspond to a specific scene of the predetermined application.
On the other hand, the conversion of each activity is known at the framework level.
For example, when a user selects a
Alternatively, you can set the user to turn on the 3D auto-sensing and execution feature in an activity called GameStart (not shown), which will automatically turn on 3d mode when entering an activity called GameStart.
On the other hand, the
For example, the user can select the
In addition, one embodiment of the present invention recognizes a pattern of a user and can set a point at which 3D should be automatically turned on. For example, in Android, if you manually turn on 3D in an activity called GameStart, you can save this point and use it from hereafter.
In contrast to the embodiment shown in FIG. 10, even when the application is set to the 3D automatic sensing function item, the 3D automatic sensing function is turned on from a specific scene instead of being switched to the 3D mode unconditionally at the time of execution of the application, Mode can be set.
11, the
If the user selects the predetermined activity 1053, the
Meanwhile, in one embodiment of the present invention, 3D formats such as side-by-side and top-bottom can also be set. For example, the user can set the 3d mode in a top-bottom manner in an activity called GameStart, and the
In the conventional 3D TV, since the specifications of the 3D image format are not unified with respect to the 3D contents and the 3D image format information is not included, the viewer must directly view the 3D TV after selecting the 3D image format.
In addition, every time the content is used, there is an inconvenience to newly select a 3D image format.
Thus, an embodiment of the present invention may store 3D image format settings for a given application and then apply automatically stored 3D format settings when using the same broadcast application.
Meanwhile, the
The video display device often has a plurality of users such as a family member, and the applications installed for each user may be different or have different preference settings. The video display device is generally used by a plurality of users at the same time in the home. However, in some cases, the video display device may be used alone.
Therefore, by storing and managing account-specific settings for each logged-in user, it is possible to prevent other users from changing the preferences of individual users or to prevent inconvenience of other users using the video display device.
Meanwhile, the
On the other hand, 3D mode-related settings (auto detection and execution, 3D type, 3D on, etc.) can be defined in advance by dividing the version of each application and the package name and managed by the server, have. Also, the pattern of usage can be updated to the server.
According to the present invention, in the case of using 3D contents, in particular, applications supporting 3D, the 3D-related setting can be performed simply and conveniently, thereby improving usability of the user.
The image display apparatus and the operation method thereof according to the present invention are not limited to the configuration and method of the embodiments described above but the embodiments can be applied to all or some of the embodiments May be selectively combined.
Meanwhile, the operation method of the image display apparatus of the present invention can be implemented as a code that can be read by a processor on a recording medium readable by a processor included in the image display apparatus. The processor-readable recording medium includes all kinds of recording apparatuses in which data that can be read by the processor is stored. Examples of the recording medium that can be read by the processor include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like, and may also be implemented in the form of a carrier wave such as transmission over the Internet . In addition, the processor-readable recording medium may be distributed over network-connected computer systems so that code readable by the processor in a distributed fashion can be stored and executed.
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the present invention.
