Patent ID: 8861835

Claim:
An optical measuring apparatus for a stereoscopic display device comprising: a test image supplier for generating a 3D test signal; a 3D display for displaying a left-eye image and/or a right-eye image based on the 3 D test signal supplied from the test image supplier; an image selection member comprising a left lens for selecting only the left-eye image displayed on the 3D display, and a right lens for selecting only the right-eye image displayed on the 3D display; and a light measuring device for measuring intensity of the left-eye image and the right-eye image transmitted via the image selection member at the position corresponding to each of plural measuring points on a screen of the 3D display, wherein the light measuring device calculates an average luminance of the left-eve image by averaging a white luminance for each of the specific measuring points of the left-eve image; wherein the light measuring device calculates an average luminance of the right-eye image by averaging an white luminance for each of the specific measuring points of the right-eye image; wherein the light measuring device calculates an interocular luminance difference corresponding to a difference between the average luminance of the left-eye image and the average luminance of the right-eye image, wherein the light measuring device is movably provided while being parallel to each of the plural measuring points on a screen of the 3D display, and wherein the plural measuring points include: a center measuring point that is set to be positioned in a center of the screen of the 3D display; first to fourth measuring points that are set to be positioned at the respective comers of the screen of the 3D display; and fifth to eighth measuring points that are set to be positioned between two neighboring measuring points of first to fourth measuring points.
