Stereoscopic image display apparatus and changeover method

A stereoscopic image display apparatus comprising:

• an image receiving device for retrieving right and left eye images of plural stereo pairs from a storage medium by one pair;
• a parallax checking device for determining parallax information of parallax of a common principal object present in each of said right and left eye images of an Nth stereo pair, where N is an integer;
• a stereo matching unit for correcting at least one particular image of said right and left eye images of said Nth stereo pair to minimize said parallax information being determined;
• a display panel for displaying an Nth three dimensional image according to said right and left eye images of said Nth stereo pair after correction;
• and
• a controller for, while said display panel displays said Nth three dimensional image, causing retrieval of said right and left eye images of an (N+1)th stereo pair and determination of said parallax information thereof with said image receiving device and said parallax checking device with respect to said (N+1)th stereo pair.
