Gamma correction is used to correct for the nonlinear relationship between luminance and brightness.
This small application produces a Lookup Table (LUT) with the PWM duty cycles which are gamma corrected to produce linear brightness changes.
When an LED emits light, gamma correction is used to account for the power-law relationship between luminance and brightness. Although often used interchangeably, luminance and brightness are not synonyms.
Luminance: The emitted light, projected per unit area measured in cd/m² (candela/ meter²).
Brightness: The perceived luminance attributed by the human eye.
