Generates an OSD signal to display a settable window. The user may set parameters related to the image quality of the 3D image through the setting window.

The setting window generated in the display unit 180 according to the OSD signal generated by the 3D image quality setting OSD generator 174b may be a 3D object. The 3D object is composed of a multi-view image, and a user may feel a 3D effect when viewing the multi-view image displayed on the display unit 180 through shutter glasses or the like. That is, in the present embodiment, an object composed of multiple view images is called a 3D object so that a user can feel a 3D effect.

The 3D image quality control unit 174 may include a parameter adjusting unit for adjusting a parameter related to the image quality of the 3D image according to a parameter set by the user through a setting window generated by the OSD generator 174b for setting the 3D image quality. have. The parameter adjusting unit included in the 3D image quality controlling unit 174 according to the present embodiment may include a 3D image sharpness adjusting unit 174c, a 3D image depth adjusting unit 174d, and a 3D image frequency adjusting unit 174e. have.

The 3D image sharpness adjusting unit 174c may adjust the sharpness of the multiple view image constituting the 3D image. For example, the multi-view image constituting the 3D image may include a left eye image viewed through the left eye of the user viewing the image display apparatus 100 and a right eye image viewed through the right eye. In the left eye image and the right eye image, disparity may exist in the image so that the user may have a three-dimensional effect when viewing through the left eye and the right eye, respectively. Therefore, when the 3D image is reproduced, the edge of the left eye image and the right eye image displayed on the display unit 180 may not match.

The 3D image sharpness adjusting unit 174c may adjust a parameter related to the sharpness of the 3D image composed of the multiple view images. The disparity between the multiple view images displayed on the display unit 180 may be related to the sharpness of the 3D image in order to give a 3D effect to the image displayed on the display unit 180. Therefore, the user may adjust the stereoscopic feeling of the 3D image by adjusting a parameter related to the sharpness of the 3D image.

The 3D image depth adjusting unit 174d may adjust the depth of the 3D image composed of the multiple view images displayed on the display unit 180. In general, the 3D image may be displayed as if it protrudes toward the user from the plane of the display unit 180 on which the multiple view image constituting the 3D image is displayed. In addition, the 3D image may be displayed as if it is positioned behind the plane of the display unit 180 where the multi-view image is displayed.

In this case, the distance between the 3D image and the plane of the display unit 180 on which the multi-view image constituting the 3D image is displayed may be referred to as a depth. The user may adjust a place where the 3D image appears to be located by adjusting the depth of the 3D image viewed by the user.

The 3D image frequency adjusting unit 174e may adjust a frequency at which the multiple view image constituting the 3D image is output to the display unit 180. The user recognizes the multi-view image as a 3D image by watching the multi-view image output to the display unit 180 through the shutter glasses. That is, using the shutter glasses, the user alternately recognizes the left eye image and the right eye image through the left eye and the right eye, respectively.

When the frequency of the shutter glasses and the frequency of the left eye image and the right eye image output to the display unit 180 are different, the user may watch an image that is out of focus or shakes. Therefore, the 3D image quality control unit 174 allows the user to set the output frequency of the multiple view image constituting the 3D image. The 3D image frequency adjusting unit 174e may adjust the output frequency of the multiple view image according to the output frequency set by the user.

Information related to the parameter adjusted by the parameter adjuster of the 3D image quality controller 174 is output to the formatter 175. As described above, the formatter 175 may convert the format of the 3D image signal input to the image display apparatus 100 to match the output format of the image display apparatus 100 and output the converted format to the display unit 180. . When the formatter 175 adjusts the format of the 3D video signal, the formatter 175 may refer to parameter information output from the 3D video quality control unit 174 and convert the format of the 3D video signal output to the display unit 180 accordingly. Can be. Therefore, the user can watch the 3D image with the image quality corresponding to the parameter set by the user.

The OSD signal output to the formatter 175 may be changed so that the window is displayed on the display unit 180. The setting window of the present embodiment is displayed on the display 180 as an OSD (S250).

The formatter 175 converts the format of the OSD signal output from the 3D image quality control unit 174 to match the output format of the display unit 180 and then outputs it to the display unit 180. The display unit 180 may display an image based on the image signal output by the formatter 175 on the screen. In the present embodiment, the display unit 180 displays a setting window on the screen.

The setting window of the present embodiment may be a 3D object. In this case, the display unit 180 displays a multi-view image constituting the setting window 3D object. The user may recognize the setting window 3D object including the multi-view image through the shutter glasses.

The user may set parameters related to 3D image quality through the setting window. The parameter adjusting unit included in the 3D image quality control unit 174 outputs the information about the parameter set by the user to the formatter 175. The formatter 175 adjusts the format of the 3D video signal to correspond to the parameter set by the user and outputs the 3D video signal to the display unit 180. Therefore, the image quality of the image based on the 3D image signal input to the image display apparatus 100 is set to correspond to the parameter set by the user (S260).
