SETTINGS
5.1.8.
BACKLIGHT
submenu
These compensation functions allow for enhancing visibility of the objects located in the
foreground, surrounded by strongly illuminated background (
BLC
) or for enhancing visibility of the
objects located near the strong light source (
HLC
). If a strong, point light source appears on the
screen, function will mask it allowing for effective observation of the scene itself (for example this
function is used to, observe licence-plates of the cars).
5.1.9. 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.
