7.5.20 Chromaticity and Color Shading
Conditions:
Projected image: VG-Prog. No.856
100% white
Focus:
Just focus point
Requirements:
(1) Chromaticity
•
An average value of chromaticity measured at ANSI nine points of 100% white
(refer to Fig. 7-2) is as follows.
X: 0.305 +/- 0.035
Y: 0.370 +/- 0.035
(2) Color Shading
•
Determine the following
∆
-values from the values of chromaticity measured at
ANSI nine points of 100% white (refer to Fig. 7-2). Each value is within specs.
∆
X1
,
∆
Y1
(specs: 0.3 or less)
The maximum value of the color-differences between eight perimeter measurement
points and the center point.
∆
X2
,
∆
Y2
(specs: 0.3 or less)
The maximum value of the color-differences between nine perimeter measurement
points.
Measurement:
Chromaticity measurement at nine points
