Abstract:
1. 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 3D test signal supplied from the test image supplier; an image selection member selectively transmitting the left-eye image or the right-eye image displayed on the 3D display; and a light measuring device providing movable in two dimensions parallel to a plane containing plural measuring points on a screen of the 3D display, wherein the plural measuring points consisting of: 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 corners 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, wherein the light measuring device measures intensity of the left-eye image and the right-eye image transmitted via the image selection member at the position corresponding to each of the plural measuring points on a screen of the 3D display, wherein the light measuring device calculates: an average luminance of the left-eye image by averaging a white luminance for each of the specific measuring points of the left-eye image; 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; a luminous non-uniformity for each of the specified measuring points of the left-eye image by subtracting the average luminance of the left-eye image from the white luminance for each of the specified measuring points of the left-eye image; and a luminous non-uniformity for each of the specified measuring points of the right-eye image by subtracting the average luminance of the right-eye image from the white luminance for each of the specified measuring points of the right-eye image.
