6. Color Uniformity
Use a CCV31F pattern box (manufactured by Dai Nippon Printing Co., Ltd.) set up at a brightness of 1500 NT and
color temperature of 5100°K with no pattern. Use the Sanyo LC9997-LE01 lens and a C-500 IR cut filter. Adjust the
exposure with ND filters so that the CCD output signal level is 500 mV. Measure the chrominance signal level and
chrominance signal phase at 16 points in the image as shown in Figure 7. Calculate the color unevenness, V
CS
(mV),
from these chrominance signal level and phase values.
