5. For DC power, no light fluctuation is existing and no compensation is needed.
5.9 Sampling group
1. Bin : Pixel binning refers to the method of combining (averaging)
pixels of blocks of neighboring same color pixels;
2. Skip : Also called "Decimation", means that a certain amount of pixels is
not read out but skipped (horizontally, vertically or in both axes). This
reduces resolution of the resulting image but introduces subsampling
artifacts.
5.10 Histogram group
1. A Histogram illustrates how pixels in an image are distributed by
graphing the number of pixels at each color intensity level. The
Histogram shows detail in the shadows (shown in the left part of the
histogram), midtones (shown in the middle), and highlights (shown in
the right part).A Histogram can help you determine whether an image
has enough detail to make a good correction;
2. This dialog shows the Histogram of current active image. Two vertical
line markers show the upper and lower limits of the intensity levels.
These markers can be dragged with your mouse. If you are looking at a
color image, the Histogram will reflect the RGB (red, green and blue
channels histogram at the same time) R (red), G (green), and B (blue)
values with lines of the same color;
3. You can also enter directly the desired values in the Left or Right
boxes below the Histogram chart for both Left and Right Histogram
boundaries;
4. Click the “ Refresh ” button to update the Histogram display if the
sample under observation is moved or changed;
5. Clicking Defaults will return the Left and Right Histogram boundaries
to its original ones;
Click Auto to locate the two boundaries automatically to get the best
Video quality.
