White Shading Adjustment - Hitachi S-3000W Operating Instructions Manual

White shading adjustment

White shading adjustment is recommended after replacing the lens. The adjustment relates to the
camera vertical coloration. If the lens includes an extender, the shading can be optimized for both
extender on and off modes.
(Vertical coloration refers to an effect whereby the image of an overall white sheet of paper tends toward
green at the top and magenta at the bottom, or vice versa.)
Adjustment steps
Install the lens on the camera (be sure to connect the lens cable).
1.
2. Set the electronic shutter to off and the gain to L (0 dB).
3. If provided, set the lens extender to off.
4. Notice that flicker can occur with fluorescent or mercury lighting. Therefore, use sunlight or halogen as
the light source.
In the auto iris mode, check that the iris is between F4 and F11. If necessary, adjust the light source
position (be sure the electronic shutter is off).
