Black shading adjustment method
Preparation
• Connect the HD waveform monitor to the SDI OUT connector.
• Set the HD waveform monitor to the RGB mode.
• Set the lens iris to CLOSE.
Adjustment Procedure
1. Adjust the gain and the black level so that waveforms can be viewed best.
2. Adjust H Saw, H Para, V Saw, and V Para for each of G-channel, B-channel, and R-channel until the waveform
on the waveform monitor becomes flat.

4-1-3. White Shading Adjustment
The White Shading menu enables the adjustment of the horizontal and vertical Saw correction level and parabola
correction level.
Note
• The White Shading adjustment cannot be executed for the correct adjustment values if the object pattern has non-
uniformity or if other conditions such as lens iris setting and zoom setting are not correctly satisfied.
• Use a full white pattern for the White Shading adjustment having uniform brightness over the entire area.
• If a full white pattern having uniform brightness over the entire area is not available, do not execute the G-channel
White Balance adjustment. Instead of it, execute the White Balance adjustment in the way of aligning the R-channel
waveform and the B-channel waveform to the waveform of G-channel.
Overview of White Shading Adjustment
• The White Shading setting menu can be used to turn White Shading correction On or Off. The White Shading
setting is turned On automatically when the power is turned On.
• The Channel Select menu enables selection of the channel (G-ch or B-ch or R-ch) to execute the H Saw, H Para,
V Saw, and V Para white shading adjustments on.
• When the Channel Select menu selects any other channel, the displays of the H Saw, H Para, V Saw, and V Para
setup values are changed to the current setup values of the channel selected by the Channel Select menu. The
changes are reflected on the H Saw, H Para, V Saw, and V Para setup values.
• The H Saw menu enables the horizontal Saw white shading correction (linear increase and decrease) level.
• The H Para menu enables the horizontal Parabola white shading correction (sensitivity correction at the horizontal
center with respect to both ends) level.
• The V Saw menu enables the vertical Saw black shading correction (linear increase and decrease) level.
• The V Para menu enables the vertical Parabola white shading correction (sensitivity correction at the vertical center
with respect to both ends) level.
