Broadcasting receiver and method for displaying 3D images

摘要

Disclosed are a method for displaying 3D images and a broadcast receiver. The method for displaying 3D images according to one embodiment of the present invention comprises the steps of: receiving broadcasting signals including video data and 3D object data; decoding the 3D object data, the 3D object data including texts or image information for a 3D object, output position information of the 3D object, and disparity information of the 3D object; obtaining parallax values from the disparity information and producing distortion compensation coefficients using the parallax values; adjusting a display size of the 3D object using the distortion compensation coefficients; and outputting and displaying the 3D object.

1. A method of processing 3D broadcast data, comprising:
receiving a broadcast signal including signaling information, video data and 3D object data; decoding the 3D object data, wherein the 3D object data includes data about a 3D object, wherein the broadcast signal includes disparity information of the 3D object; acquiring a parallax value from the disparity information and calculating a distortion compensation factor using the parallax value, wherein the distortion compensation factor is calculated by the distortion compensation factor=(an interocular distance value−the parallax value)/an interocular distance value; adjusting a display size of the 3D object by multiplying the display size of the 3D object by the calculated distortion compensation factor; and displaying the 3D object having the adjusted display size.
