Gamma Correction#

The Gamma Correction feature available on blaze cameras enables gamma correction on intensity images.

This is a nonlinear operation to lighten dark areas of the image.

How It Works#

When you enable the GammaCorrection parameter, a gamma of 0.4 (= 1 / 2.5) is applied to the intensity image. The resulting data is scaled to preserve the original full-scale 16-bit image. The following formula illustrates this:

OUT = (216 - 1) * (IN / 216 ) ^ (1 / 2.5)
