6. 5 Shading Correction
Due to the lens used or the environmental condition, color shading may occur at the upper and lower edge of the
screen. If this happens, the shading correction function can be used to decrease the amount of color shading. For
shading correction of the unit, SET (Automatic shading correction), MANUAL (Manual shading correction), and OFF
(no shading correction) modes are provided. Select the mode on the OPTION menu. (Refer to the item “7.2 (8) (8.1)
Changing shading correction mode”.)

Implement shading correction after white balance adjustment by shooting a white object that fills the screen in
the proper video level.
