Shading correction
Owing to technical circumstances, the interaction of recorded objects with
one another, optical effects and lighting non-homogeneities may occur in
the images.
Because these effects are normally not desired, they should be eliminated as
far as possible in subsequent image editing. The camera has automatic shad-
ing correction to do this.
Provided that a shading image is present in the camera, the on/off bit can
be used to enable shading correction.
The on/off and ShowImage bits must be set for saved shading images to be
displayed.
Note
L
Always make sure that the shading image is saved at
the highest resolution of the camera. If a lower resolu-
tion is chosen and ShowImage is set to true, the image
will not be displayed correctly.
The shading image is computed using the current video
settings. On fixed video modes the selected frame rate
also affects the computation time.
The build process will not work, if a MONO16/RGB16
format is active.
