Patent ID: 8704880

Claim:
An optical measuring apparatus of stereoscopic display device comprising: a test image supplier for generating a 3D test signal; a 3D display for displaying at least one image of a left-eye image and a right-eye image based on the 3D test signal supplied from the test image supplier; an image selection member for selectively transmitting the at least one image displayed on the 3D display; and a light measuring device that measures luminance of the at least one image transmitted via the image selection member and calculates 3D image crosstalk of the at least one image based on the measured luminance; wherein, the 3D image crosstalk includes at least one of interocular crosstalk for the left-eye image and right-eye image, GTG (gray-to-gray) interocular crosstalk for each viewing angle and interocular crosstalk for each viewing angle of the 3D display, and a horizontal angle and a vertical angle of the viewing angle are changed within a range from 0° to 90°, and wherein the image selection member is provided at an interval of at least 10 mm from the light measuring device, wherein the optical measuring apparatus is installed inside a dark room maintained at an illumination of 1 Lux or less, a temperature of 20° C.±5° C., a relative humidity of 25% to 85%, and a pressure of 86 kPa to 106 kPa, and wherein a measuring distance between the 3D display and the light measuring device is above 2 meters, or 3L, wherein, ‘L’ is a height, width, or diagonal length of the screen of the 3D display.
