Pattern Name
3D Color Ramp
Application: This is a 3D pattern used to test 3D color uniformity
and crosstalk or extinction ratio.
Description: There are 4 pairs of horizontal color bars. Each bar
depicts a color gradation from red to purple; two from left to right
and one from right to left.
Method – Color uniformity:
1. Close left eye to view image from right eye.
2. Assess the color gradation on each bar.
3. Close right eye to view image from left eye.
4. Subjectively compare the images to assess color
uniformity.
Method – Crosstalk (extinction ratio):
1. Close left eye to view image from right eye.
2. Verify that the bottom bar is extinguished. The extent to
which the bar is not extinguished represents the amount
of crosstalk.
3. Repeat for a test of the left eye
