Claim:
A crosstalk evaluation system of a stereoscopic image display, the system comprising: a display element configured to alternately display left and right eye images each having an i-gray level and a j-gray level, where “i” and “j” are an integer; a luminance meter configured to sense luminances of the left and right eye images displayed on the display element; and a computer configured to calculate a 3D crosstalk at the i-gray level of the left eye image affected by the j-gray level of the right eye image and a 3D crosstalk at the i-gray level of the right eye image affected by the j-gray level of the left eye image based on a luminance information received from the luminance meter while changing the i-gray level and the j-gray level, wherein the 3D crosstalk at the i-gray level of the left eye image affected by the j-gray level of the right eye image and the 3D crosstalk at the i-gray level of the right eye image affected by the j-gray level of the left eye image are calculated based on the following Equations: CTL i , j =  L i , j - L i , i L j , i - L i , i ⁢  × 100 ⁡ [ % ] , ⁢ CTR i , j =  R i , j - R i , i R j , i - R i , i  × 100 ⁡ [ % ] where CTL i,j is the 3D crosstalk at the i-gray level of the left eye image affected by the j-gray level of the right eye image, L i,j is a luminance at the i-gray level of the left eye image affected by the j-gray level of the right eye image, L j,i is a luminance at the j-gray level of the left eye image affected by the i-gray level of the right eye image, CTR i,j is the 3D crosstalk at the i-gray level of the right eye image affected by the j-gray level of the left eye image, R i,j is a luminance at the i-gray level of the right eye image affected by the j-gray level of the left eye image, and R j,i is a luminance at the j-gray level of the right eye image affected by the i-gray level of the left eye image.
