Abstract:
A method for determining the position of an observer, and an observer-tracking 3-dimensional display system and method using the method are provided to show an observation position to an observer by using an indicator when the observer is not located at a 3-dimensional stereo image observation position. An observer-tracking 3-dimensional display system includes an image acquisition unit(31), an observer position tracking unit(32), and a guide unit(33). The image acquisition unit acquires an image of an observer. The observer position tracking unit extracts 3-dimensional position information of the observer from the image of the observer and generates an observer position indication control signal. The guide unit shows the best observation position to the observer according to the observer position indication control signal.

A method for synchronizing a 3D motion-picture includes a step of determining an edge in at least one frame of a color moving picture and at least one frame of a depth map moving picture related to the color moving picture and a step of synchronizing the color moving picture and the depth map moving picture based on a detected edge.
Abstract:
A method for synthesizing a multi-view image using two-dimensional disparities is disclosed. The method comprises the steps of: searching corresponding pixels with respect to respective pixels in a left image and a right image to draw two-dimensional disparities, and generating a two-dimensional disparity map, based on two-dimensional disparities of the respective corresponding pixels; and combining a warped left image obtained by moving the respective pixels in the left image with a warped right image obtained by moving the respective pixels in the right image, based on the two-dimensional disparity map, to generate at least one intermediate image. The two-dimensional disparities consist of horizontal disparities and vertical disparities. The warped left image is obtained by moving the respective pixels in the left image, based on the number of the intermediate images. The warped right image is obtained by moving the respective pixels in the right image, based on the number of the intermediate images.
