Intermediate vector interpolation method and three-dimensional (3D) display apparatus performing the method

摘要

A method of generating an intermediate image between a first frame and a second frame, using the first frame and a third frame successively received from a first camera and the second frame and a fourth frame successively received from a second camera. The intermediate image generating method includes: calculating and summing pixel value differences between the first frame and the third frame in units of a block; determining whether or not a center pixel of a block has motion; calculating current disparity vectors corresponding to motion vectors between the first frame and the second frame, and calculating previous disparity vectors corresponding to motion vectors between the third frame and the fourth frame; and generating the intermediate image using the current disparity vectors if the center pixel of the block has motion, and calculating an intermediate value of the previous disparity vectors and generating the intermediate image using the intermediate value of the previous disparity vectors if the center pixel of the block has no motion.
