IONOS IP - AWB
IONOS IP CORE 
Automatic White Balance  - AWB

 

 

 

Overview
 
In order to provide high quality images, acquisition is most important in respect to all further processing steps. A whole variety of current image sensors possess incorrect color rendition due to so called cross color effects. This effects leads to wrong color images (e.g. green with too much blue).
 
 
Goal
 
Modification of each single color channel by a 3x3 correction matrix.
 
red-out =rr*red+rg*green+rb*blue
green-out =gr*red+gg*green+gb*blue
blue-out =br*red+bg*green+bb*blue
