And the whiteness of the right eye image is calculated based on the chromaticity coordinates of the right eye image measured by the optical meter at a central measurement point set at a screen center portion of the 3D display. 17. The method of claim 16,
The analyzing unit further calculates the binocular color difference by subtracting the whiteness of the right eye image from the whiteness of the left eye image. The method of claim 7, wherein
The analysis unit,
Calculating the whiteness of each measurement point of the left eye image based on chromaticity coordinates of each measurement point of the left eye image measured by the optical meter at each of the center and the plurality of edge measurement points set on the screen of the 3D display,
3D display, wherein the whiteness of each measurement point of the right eye image is calculated based on chromaticity coordinates of each measurement point of the right eye image measured by the optical meter at each of the center and the plurality of edge measurement points set on the screen of the 3D display. Optical measuring device. The method of claim 18,
The analysis unit,
Calculating the color unevenness of each edge measurement point of the left eye image by subtracting the whiteness of each of the edge measurement points of the left eye image from the whiteness of the center measurement point of the left eye image,
And a color nonuniformity for each edge measurement point of the right eye image is calculated by subtracting the central measurement point whiteness of the right eye image from each of the whiteness for each edge measurement point of the right eye image. The method of claim 7, wherein
Any one of the left eye image and the right eye image is a full screen grayscale image that is changed from a full screen black grayscale to a full screen white grayscale in a predetermined grayscale unit every predetermined frame,
And the other one of the left eye image and the right eye image is a full screen white image, a full screen black image, or the full screen grayscale image. 21. The method of claim 20,
The analysis unit,
Calculating a gamma value of a left eye image based on a brightness for each gray level of the left eye image measured by the optical meter at a central measurement point set at a screen center of the 3D display,
And a gamma value of the right eye image is calculated based on luminance of each right gray level of the right eye image measured by the optical meter at the central measuring point.
