SHARPNESS (0-255) Increases or decreases the sharpness of the picture. Too high sharpness can
make the image too harsh and show more noise as well as line flicker at the edge of
object in the picture.
HUE (0-255) Increases or decreases the hue of the picture.
GAIN (0-255) Increases or decreases the color gain of the picture.
5.1.6. ATR (Adaptive Tone Reproduction) submenu (WDR)
The ATR feature improves the dynamic range and the visibility of the image by providing the
optimal gradation compensation of the image in one field. This is achieved by two steps image
processing: luminance compression and contrast enhancement, so that the tone can be enhanced at
highlighted and dark areas.
LUMINANCE ( LOW, MID, HIGH ) Compresses the highlighted area and enhances the dark area so
that the entire image can converge toward the medium level. LOW will compensate
minimally and HIGH will average out the image. With setting HIGH , the image may
look less contrastive and noise may increase in the dark area.
CONTRAST ( LOW, MIDLOW, MID, MIDHIGH, HIGH ). Adjusts the strength of the image contrast.
If set to too high, the dark area may lose detail and the high luminance area may
saturate.
5.1.7. MOTION DET (Motion Detection) submenu
This menu allows for turning a built-in motion detection feature on or off. Motion detection
may simultaneously be conducted in four independent zones (with their size and location selected
by user). Detection results
blinking frame of the area on the screen. When ON is selected, click SET
to bring up the MOTION DET sub-menu for further settings.
DETECT SENSE (0-127) Adjusts the sensitivity for detecting motion. A higher value is more sensitive.
BLOCK DISP (ON/ENABLE/OFF) Enables or disables displaying luminance highlighted blocks for the
area where the motion is detected.
MONITOR AREA (ON/OFF) Displays four windows as programmed in sizes and positions. If the
motion is detected window is blinking;
AREA SEL (1,2,3,4/4) defines the monitoring frame to be set.
TOP/BOTTOM/LEFT/RIGHT sets the monitoring frame of selected area.
5.1.8. PRIVACY submenu
This menu allows for enabling four privacy zones. If this option is turned on, desired part of
the screen is masked using rectangular zones. Pressing SET displays submenu which allows for
adjusting privacy settings .
AREA SEL (1,2,3,4/4) sets the mask frame to be adjusted.
TOP/BOTTOM/LEFT/RIGHT sets the mask frame selected by the AREA SEL parameter (differs for
NTSC and PAL).
