Reduction of spatially non-uniform 3D crosstalk for stereoscopic display using shutter glasses

In 3D technology, when the image isolation between the left image and right image is incomplete, each eye can see not only wanted image but also unwanted image as well. And for some types of 3D technology, this leakage of the unwanted image is not spatially uniform. In making this leakage less noticeable by the modification of the 3D image data, one value of the modification condition can make the leakage smaller at one position but larger at other positions of the 3D display due to this non-uniformity. When the modification conditions dependent on the display positions are determined and applied to the image data, the leakage is observed to reduce at all the positions of the 3D display.
