Set the backlight compensation (BLC)
This feature tells the camera to adjust its total exposure (iris and shutter) to
ignore the brightest areas of the image, and instead concentrate on darker areas.
In the Setup Menu, go to Backlight and select the options to be modified:
Off: Option is disabled. Default setting.
BLC (Backlight Compensation): BLC can improve image quality when the
background illumination is high. It prevents the object in the center from
appearing too dark.
HLC (Highlight Compensation): HLC masks strong light sources, giving
darker areas more detail. It is often used to help identify vehicle license plate
numbers, for example.
Adjust the picture characteristics
In the Setup Menu, go to Pict Adjust and select the options to be modified.
Set the camera image characteristics such as brightness, contrast, sharpness,
hue, and saturation (called “Gain” here) of the picture. The parameters of each
can be set between 0 and 255.
Use the mirror function to flip the camera image so that it is correctly orientated
for viewing. The image is flipped horizontally when the function is enabled.
Default setting is Off.
Set the ATR level
The ATR feature (adaptive tone-curve reproduction) is similar to WDR (Wide
Dynamic Range). It is used when there are both bright and dark areas in the
picture. It helps improve the contrast between objects.
In the Setup Menu, go to ATR and select the desired luminance and contrast
parameters.
