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.
