11.3.7 Gamma
This function compensates any nonlinearity in human eye light perception.
For this correction, the corrected pixel intensity (Y') is calculated from the original intensity of the
sensor's pixel (Y
original
) and correction factor ɣ using the following formula (in oversimplified ver-
sion): Y' = Y
ɣ
original
Ill.5: Non-linear-perception of the human eye
1 Perception of brightness 2 Energy of light
The values of the calculated intensities are entered in Look-Up-Table. This will overwrite any
existing values in LUT.
INFO
If function LUT is disabled by software, the gamma correction function is disabled as well.
INFO
Setting the gamma value at simultaneous image acquisition may cause visual effects in cam-
eras with long readout time, since access to LUT is not locked against the pixel stream.
This behavior can be avoided by camera stop prior to the setting (AcquisitionStop).
