Gamma Function
The gamma function corrects the output signals from the camera beforehand (reverse
correction), taking into consideration the light-emitting properties of the monitor display.
As the light-emitting properties of the monitor are not linear, the entire image may be
darker or the gradation in the dark areas may be less noticeable when camera outputs are
displayed without processing.
The gamma function can be used to correct the camera signals with an opposite-direction
curve and produce a display that is close to linear.
■
To use the gamma function
Configure the settings as follows.
You can use the LUT function to configure a curve with more detailed points.
For details, see “Lookup Table (LUT)”.
