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
