BLC Settings: Back Light Compensation (BLC) is used to make the subject appear clearer when it is set
against a bright background. This option is not available when you select Auto for Focus Mode setting.
Select On or Off to enable or disable the BLC function.
Noise Reduction: This limits the amount of digital “video noise” that is usually found in any video
stream, and helps to reduce file size. Select ON / OFF to enable / disable the Noise Reduction
function. Slide the Level bar to set up the level. The higher the level, the more the reduction.
WDR Mode: This feature provides clearer images when both of the very bright and dark areas
simultaneously appear on the camera view. Select one from the 5 modes that delivers the best image
quality.
 OFF: Select to disable the WDR function.
 Auto: Select to automatically switch on / off the WDR function where intensity of illumination
on the image varies excessively.
 Mode 1: This is the WD Mode, which can correct blocked-up shadows and blown-out highlights
in accordance with the intensity difference.
 Mode 2: This is the Exposure Ratio Mode, which allows you to further adjust the Exposure Ratio
(shutter speed) in the field below.
 Mode 3: This is the Histogram Mode, which uses a histogram to correct blocked-up shadows
and blown-out highlights.
White Balance Settings: Select the mode that delivers the best quality image for the camera’s light
environment. You can click the Push button on the right side to instruct the camera to the selected
mode. This is like a “semi-automatic” way to adjust the White Balance mode to suit the user.
Mode:
 Auto: Select to let the camera automatically adjust the White Balance. In the Auto mode the
camera computes the white balance value output using color information from the entire
screen. It outputs the proper value using the color temperature radiating from a black subject
based on a range of value from 3000 to 7500K. You can further adjust the AWB Level in the field
below.
 Manual: Select to adjust the Red and Blue values yourself in the fields below this field.
 Indoor: Select to use the default settings for indoor environments. In the Indoor mode, the
camera uses 3200K as the base value.
 Outdoor: Select to use the default settings for outdoor environment. In the Outdoor mode, it
uses 5800K as the base value.
 One Push: Select to enable the Push button next to the Mode drop-down field. This will
allow you to force the camera to readjust the white balance every time you push the Push
button. The lens will hold the same focal position until the next trigger command is received.
This function helps to prevent incorrect focusing in dark environments.
 Outdoor Auto: This function is specially designed for outdoors, allowing the camera to
automatically capture images with natural white balance in the morning and evening.
