Picture Settings - Alc; Picture Settings - Enhance - Sony SNC-HMX70 User Manual

Picture settings – ALC
ALC mode
Select the mode for automatic light-level control:
– Fluorescent 50 Hz
– Fluorescent 60 Hz
– Standard
ALC level
Adjust the video output level (-15 to 0 to +15).
Select the range within which the ALC will operate. A
positive value is more useful for low-light conditions; a
negative value is more useful for very bright conditions.
Saturation (av-pk)
The saturation (av-pk) slider configures the ALC level
so that it controls mainly on scene average level (slider
position -15) or on scene peak level (slider position
+15). Scene peak level is useful for capturing images
that contain car headlights.
Exposure/frame rate
Automatic exposure
Select to let the camera automatically set the optimum
shutter speed. The camera tries to maintain the selected
shutter speed as long as the light level of the scene
permits.
• Select the minimum frame rate for automatic
exposure.
(The values available depend on the value set for the
Base frame rate in the Installer Menu.)
Default shutter
The default shutter improves the motion performance in
auto exposure mode.
• Select a default shutter speed.
Fixed exposure
Select to set a fixed shutter speed.
• Select the shutter speed for fixed exposure. (The
values available depend on the value set for the ALC
mode.)
Day/night
Auto - the camera switches the IR cut-off filter on and
off depending on the scene illumination level.
Color - the camera always produces a color signal
regardless of light levels.
Monochrome - the IR cut-off filter is removed, giving
full IR sensitivity.
Day-to-night switchover
Adjust the slider to set the video level at which the
camera in Auto mode switches from color to
monochrome operation (-15 to +15).
A low (negative) value means that the camera switches
to monochrome at a lower light level. A high (positive)
value means that the camera switches to monochrome at
a higher light level.
Night-to-day switchover
Adjust the slider to set the video level at which the
camera in Auto mode switches from monochrome to
color operation (-15 to +15).
A low (negative) value means that the camera switches
to color at a lower light level. A high (positive) value
means that the camera switches to color at a higher light
level.
(The actual switch-over point might change
automatically to avoid instable switching.)
Note
To ensure stability when using IR illuminators, use the
alarm interface for reliable Day/Night switching.
Picture settings – Enhance
Sharpness level
The slider adjusts the sharpness level between -15 and
+15. Zero position of the slider corresponds to the
factory default level.
A low (negative) value makes the picture less sharp.
Increasing sharpness brings out more detail. Extra
sharpness can enhance the details of license plates,
facial features and the edges of certain surfaces but can
increase bandwidth requirements.
Backlight Compensation
Select Off to switch off backlight compensation.
Select On to capture details in high-contrast and
extremely bright-dark conditions.
Select Intelligent Auto Exposure to capture object
detail in scenes with people moving in front of a bright
background.
Contrast enhancement
Select On to increase the contrast in low contrast
conditions.
Intelligent Dynamic Noise Reduction
Select On to activate intelligent Dynamic Noise
Reduction (DNR) which reduces noise based on motion
and light levels.
