Gamma Correction Factor
The following graphic shows LUT output data as a function of the gamma correction factor
programmed by the user. An 8-bit LUT is shown as an example and importantly the graphic is not
to scale.
• As Gamma Correction is reduced in value to the minimum allowed, the nonlinear output of
acquisition data through the LUT effectively boosts low value data.
• As Gamma Correction is increased in value to the maximum allowed, the nonlinear output of
acquisition data through the LUT effectively reduces low value data.
