Gamma Correction

 

 

 

Overview

 

Pixels are illuminated in a linear way. To provide pixel data to common video systems a conversion to a non-linear value encoding may be needed.

 

 

Goal

 

Conversion of a RGB-input signal from linear to non-linear value or otherwise under usage of arbitrary gamma correction factors.
