Lut Values; Gamma Function; To Use The Gamma Function - IAI GO-2400M-PMCL User Manual

■ LUT values

LUT values range from 0 at the lowest to 4095 at the highest. Linear interpolation is used to calculate
LUT values between the index points.

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.

Note
You can use the LUT function to configure a curve with more detailed points. For details, see "LUT (Lookup Table)"
(page 40).
Interpolation using the average values of data to the left
and right is used to determine values between points.
