Abstract:
1. A method of controlling view of a stereoscopic image, the method comprising: (a) simultaneously detecting 3D position information of a plurality of users, averaging the 3D position information detected for a predetermined frame period, generating a left eye image and a right eye image for each of the 3D position information and changing view angle and depth information of the left eye image and the right eye image displayed on a display according to the 3D position information; and (b) combining at least two of a spatial division technique spatially dividing light from the display, a time division technique temporally dividing light from the display and a polarization division technique dividing light from the display into lights having polarization characteristics, which are different from one another, to divide the left eye image and the right eye image for the each user by using the combined techniques, and producing a binocular disparity for the each user, wherein the 3D position information of each of the users includes X-axis position information of the user's face, Y-axis position information of the user's face, and Z-axis position information of the user's face, and wherein the method of step (a) includes analyzing a 3D position information detected in a current frame to determine whether a 3D position information detected in a previous frame exists, setting a first detection range to a region around a position of the user's face detected in the previous frame if the 3D position information detected in the previous frame exists in 3D position information detected in the current frame, setting a second detection range to an entire region of the user detected in the current frame if the 3D position information detected in the previous frame does not exist in the 3D position information detected in the current frame and detecting the user's face within the first or second detection range by using a face detection algorithm to extract a position of the user's face as the 3D position information.
