Shading correction

Shading correction is used to compensate for non-homogeneities caused by 
lighting or optical characteristics within specified ranges.

To correct a frame, a multiplier from 1...2 is calculated for each pixel in
1/256 steps: this allows for shading to be compensated by up to 50 %.

Besides generating shading data off-line and downloading it to the camera, 
the camera allows correction data to be generated automatically in the cam-
era itself.

How to store shading image

After generating the shading image in the camera, it can be uploaded to the 
host computer for nonvolatile storage purposes.

The following pictures describe the process of automatic generation of cor-
rection data. The line profiles were created using MVTEC's 

ActivVision Tools

.

•

On the left you see the source image with non-uniform illumination.

•

The graph on the right clearly shows the brightness level falling off to 
the right.

By defocusing the lens, high-frequency image data are removed from the 
source image, therefore its not included in the shading image.

Note

L

•

Shading correction does not support the mirror func-
tion.

•

If you use shading correction, don’t change the mirror 
function.
