That is, a plurality of OSD objects are displayed on the
Here, at least one of the first OSD object or the second OSD object may be composed of a plurality of view-point images. That is, both the first OSD object and the second OSD object may be composed of a plurality of view-point images, and either one of them may be composed of a plurality of view-point images. In this case, the depth value of the OSD object described above can be added or subtracted by the interval between the plurality of viewpoint images constituting each OSD object, i.e., the left eye image and the right eye image.
The
The user input unit may receive a user setting signal from a remote control device connected to the video display device. The remote control device may be a remote control device that senses the motion of the remote control device and transmits a signal including a command corresponding to the motion to the image display device.
If the user inputs a user setting signal using a remote controller such as a space remote controller, the

Accordingly, when the user setting signal is an OSD position control signal for changing the display position of the OSD object, the
Also, the user setting signal may be an OSD display control signal for changing the display state of the OSD object. The display state of the OSD object may mean the color temperature, transparency, brightness, and sharpness of the OSD object. Therefore, the OSD display control signal includes information on which OSD object is to be targeted and information on how to change the color temperature, transparency, brightness, or sharpness of the OSD object.
Here, the display state of the OSD object may be added or subtracted based on the depth value of the OSD object. That is, the color temperature, transparency, brightness, or sharpness of the OSD object may be added or subtracted according to the depth value set in the OSD object or the depth of the OSD object. For example, when OSD objects are displayed in multiple layers, OSD objects belonging to the same layer or OSD objects having the same depth value have the same color temperature, transparency, brightness or sharpness.
