Gamma Correction - HIKVISION MV-CA003-30GC User Manual

3.9.6 Gamma Correction

The camera supports Gamma Correction. Normally, the output of the camera chip and
the number of photon that the sensor (on the chip) received are linear. And Gamma
Correction provides a non-linear output. If the Gamma value is between 0.5 and 1, the
image brightness decreases while the brightness of the dark area increases. If the
Gamma value is between 1 and 4, the image brightness increases while the brightness
of the dark area decreases.
