Patent ID: 7161614

Claim:
A device for converting a two-dimensional video into a three-dimensional video, characterized by comprising: a field memory for storing for each field a two-dimensional video signal inputted from a video signal source; motion vector detection means for detecting for each area of an input video a motion vector corresponding to movement between fields of the inputted video signal; readout means for reading out, out of the video signals stored in the field memory, the video signal delayed from the inputted video signal by a delay found from the motion vector for each area detected by the motion vector detection means from the field memory; switching means for outputting one of the inputted video signal and the video signal read out of the field memory and the other video signal, respectively, as a left eye video signal and a right eye video signal on the basis of the direction of a horizontal component of the motion vector for each area detected by the motion vector detection means; feature extraction means for extracting for each area of the input video a video feature from the inputted video signal; parallax calculation means for calculating, on the basis of the image feature for each area of the input video extracted by the feature extraction means, a depth for the area and calculating a parallax for the area from the calculated depth for the area; parallax correction means for correcting the parallax for each area calculated by the parallax calculation means depending on the magnitude of the motion vector for the area detected by the motion vector detection means; and phase control means for correcting, on the basis of the parallax for each area corrected by the parallax correction means, phases for the area of the right eye video and the left eye video outputted by the switching means, and outputting the videos as a stereoscopic video signal.
