METHOD AND DEVICE FOR COMPENSATING FOR SYNCHRONIZATION BETWEEN LEFT AND RIGHT IMAGE FRAMES IN THREE-DIMENSIONAL IMAGING SYSTEM, AND REPRODUCTION DEVICE AND METHOD

摘要

A device for compensating for synchronization between left and right image frames in a three-dimensional imaging system of the present invention comprises: a similarity computation unit for computing the similarity between left and right image frames on the basis of a scene change time of the left and right image frames; a left and right image frame difference value extraction unit for finding a stereoscopic pair on the basis of the similarity and extracting a temporal frame difference value between the left and right image frames; and a left and right image frame synchronization compensation unit for performing synchronization by moving any one image between the left and right image frames in a time axis on the basis of the left and right image frame difference value. Therefore, a temporal difference between left and right image frames can be computed and, if necessary, the temporal difference be compensated, thereby overcoming existing inconveniences of having a person directly compensate for synchronization by checking with the naked eye.
