Exposure / White balance
Configure Exposure and White Balance and Digital Noise Reduction for best image quality here.
Some options will only appear under certain exposure / White balance modes. We will describe
each in detail below.
Exposure Mode - Auto
In Auto Exposure Mode, you control the image brightness by configuring the AE Reference
Target and Slowest Auto Shutter.
AE Reference Target
means the Auto Exposure reference target, which can be considered as
the
“Target Brightness on Sensor”. The camera will use several internal parameters to achieve
best quality with reference to this.
The higher this value, the brighter the overall scene, and
the more noise at night.
Slowest Auto Shutter
means the longest allowed exposure time for each frame. In extreme low
light conditions, the exposure time is automatically increased to get more light into one image. If it
extends beyond the interval between frames, (i.e. 1/30 second), then the frame rate will be
automatically reduced.
Longer time in this value gives clearer images at night for slow
moving objects, but more motion blur for fast moving objects.
White balance
weights the proportion of color in scene and recreates the most realistic color.
Usually this function is performed seamlessly in the background in auto mode. In some cases you
may want to fix the color proortions of your view. Wait until you like the color on screen. You can
hold a piece of white paper in front of camera for reference, then wait until you like the current
value to click on the
“Hold” button to the right. This will lock the current value and enter the
manual white balance mode.
