III. Gamma Curve:
1. Change Timing and pattern of pattern generator:
Timing: NTSC (H: 15.73 KHz, V: 29.96 Hz)
Pattern: 100% blue
2. Adjust Gamma Index and Red/Green/Blue Gamma to fit mars video gamma
curve.

Procedure:
I.
Offset adjustment:
1. Black coordinate spec:
Osram lamp Oshio lamp
X0
0.281 0.01
0.313 0.01
Y0
0.311 0.01
0.329 0.01
2. The variance of color coordinate via Pb offset and Pr offset:
X

3. If we line the x and y, then the Pb offset is the shift action and the Pr offset is
the rotational action.
4. Connect power, YPbPr Video into projector.
