Automatic conversion in a 2D/3D compatible mode

摘要

The invention concerns a device and a method for generating on a defined display screen of determined size (SS) a 3D image including a left view( 1) and a right view (2) from an incoming video signal to be viewed at a distance by a viewer. The device comprises:
- Means for measuring the distance (D) between the viewer and the display;
- means 7 for determining a disparity threshold value in relation with the determined size of the display screen 5 and the measured distance 6 to achieve a 2D and 3D compatibility level;
- means 4 for editing a disparity map corresponding to the values of disparity between the left and the right views;
- means 8 for analyzing with an histogram the disparity values of the disparity map in comparison to the determined threshold value;
- and means 9 for replacing one of the left or right view by a view interpolation so that the disparity level of the histogram is below the determined threshold value, if the disparity level of the histogram is above the determined disparity threshold value.
