Abstract:
1. An apparatus for measuring picture quality of a stereoscopic display device comprising: a pattern generator generating a right-eye moving picture pattern and a left-eye moving picture pattern which move at a predetermined scroll speed; a Three-Dimensional (3D) display device displaying the right-eye moving picture pattern and left-eye moving picture pattern inputted from the pattern generator, on a screen; a polarization member selectively passing the right-eye moving picture pattern and left-eye moving picture pattern displayed on the 3D display device; a following camera following respective boundary portions of the right-eye moving picture pattern and left-eye moving picture pattern, which pass through the polarization member and are incident on the following camera, to measure luminance; and an analyzer analyzing the luminance measured by the following camera to generate a Moving Picture Response Curve (MPRC), calculating an artifact width on the basis of the MPRC, and calculating a 3D motion artifact width by dividing the artifact width by the scroll speed, wherein each of the right-eye moving picture pattern and left-eye moving picture pattern comprises a first grayscale pattern area having a grayscale level within a range from a black grayscale level to a white grayscale level, and a second grayscale pattern area having the same grayscale level as the first grayscale pattern area, or a grayscale level different from the first grayscale pattern area; and wherein the following camera follows a boundary portion between the first and second grayscale pattern areas of each of the right-eye moving picture pattern and left-eye moving picture pattern to measure luminance.
