Manual shutter settings. Entering this mode allows to set shutter speed
in 1/120000s ~ 256 x 1/50s range.
AGC -
Auto gain control function which may be set either to LOW, MIDDLE or HIGH. The higher
level, the bigger it’s sensitivity to changes in illumination. Setting manual gain value is also possible.
Please keep in mind, that increasing gain brightens the picture but increases noise as well.
SSNR
- Noise reduction function. May be set either to LOW, MIDDLE or HIGH.
Note: Active DNR function may slightly degrade the picture.
SENS-UP
- Enables/disables slow shutter mode. Function automatically elongates exposure time
in low-illumination conditions which enhances the image. Please remember that when elongating
exposure, noise level goes up and so does the brightness of the picture. This mode allows to set
multiplier for the basic opening time (1/50s) in x2 ~ x256 range.
