The greater the shutter value the brighter the screen is but the more the residual images of
objects there are.
If the min shutter value is large, it can cause noise, spots and white areas but still operate normally.
If you do not use the AGC mode on the exposure menu, it cannot be set above 1/60sec.
Depending on the setting range of the minimal/maximal shutter, the screen exposure can
become saturated.
:
The higher the gain level, the brighter the
screen - but the greater the noise.
This function reduces the background noise in a low luminance environment.
OFF : Deactivates SSNR4. Noise is not reduced.
ON : Activates SSNR4 so that noise is reduced.
When adjusting the noise reduction level in the SSNR4 mode, remember that the higher the level
set, the more the noise level will be reduced, as will the brightness of the image.
