摘要： The present invention relates to a method for multiplexing an optimal 3D image, by detecting inhomogeneity and alignment error of lens in a lenticular 3D LCD monitor, minimizing the image distortion caused by the detected error, and considering the viewer's position.Thus, the method in accordance with the present invention is characterized by supplementing the mapping table for compensating the image distortion to the mapping table representing the relationship between N original view images and a multi-view image multiplexed to a 3D image. Thus, the present invention discloses a method for detecting the alignment error and inhomogeneity of lens by predicting the alignment error and inhomogeneity of lens in 3D monitor using intentionally generated test images, calculating the image index difference between the sub-pixel having to be originally observed from a viewer's eyes and the practically observed image pixel. Moreover, the present invention discloses a method for compensating the distance of a viewer by calculating the index difference between the sub-pixel having to be observed by the viewer located at optimal viewing position and the sub-pixel observed at the practical viewer's position, in the method for compensating the image distortion according to a viewer's position.

摘要： A method of detecting the alignment error of lenses and reducing image distortion attributable to the alignment error in a lens-type 3-dimensional liquid crystal display monitor. A method of detecting the alignment error of lenses in a 3D display using a purpose-built test pattern image, which predicts the alignment error in such a way as to calculate variation in view indices of pixels in a lateral direction, observed by an eye of an observer, if there is alignment error in the lenses. A method of compensating for image distortion in a 3D monitor, including the steps of finding the relationship between the pixels of a Liquid Crystal Display (LDC) panel and the pixels of observed images, which are determined depending on the location of an observer; and compensating for image distortion attributable to the rotational and translational alignment error of the lenses based on the found relationship.
