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
