6. 5 Shading Correction
Due to the lens used or the environmental condition, color shading may occur at the upper and lower side of
the screen. In this case, the shading correction can decrease the color shading. For the 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 (7) (7.3)
Changing shading correction mode”.)

shading correction cannot be performed.

[DISP] button to remove them from the screen. If the camera Is in Freeze Mode, perform the
cancellation procedure (refer to the item “6.6 Freeze Operation") to return the camera to Live Image
Mode.
