Patent ID: 7126990

Claim:
An apparatus for controlling a stereo video display with non-stereo video source, comprising: a memory for storing a current frame, a previous frame of the current frame, and a next frame of the current frame that is in preparation, wherein the current frame and the previous frame are for a dextral image and a sinistral image of a stereoscopic image respectively; a read/write controller for controlling write-in addresses on the memory for the current frame and the next frame, and reading order of the current frame and the previous frame; and a motion analyzer for calculating a next overall motion direction of the next frame in relation to the current frame, and comparing the next overall motion direction to a previous overall motion direction of the current frame in relation to the previous frame, in order to control the action of the read/write controller to read from and write to the memory, so that a corresponding relation between the current and the next frames and the dextral and the sinistral images will be changed when a horizontal relation between the next overall motion direction and the previous overall motion direction is changed.
