Gamma

Cameras encode luminance differently than the human eye. While the human eye has an emphasis on the darker end of the spectrum, a camera encodes luminance on a linear scale. To compensate for this effect, gamma correction is applied to either darken or brighten the image and make it closer to human perception.

Note

The Gamma correction value ranges between 0.25 and 1.5 for Zivid cameras.

The lower the Gamma value, the lighter the scene will appear. If the Gamma value is increased, then the scene will appear darker.
