8. Capturing Images 90
Similarly, the vertical binning mode combines the values of adjacent pixels on the same column (see Fig-
ure 8.4 and Figure 8.7), and the vertical size of the acquired image is then reduced by a factor related to
the chosen binning factor.
The combined binning mode enables both binning modes (see Figure 8.5 and Figure 8.8) and generates
an image whose resolution is halved in both dimensions.
User can choose between two binning types: sum or average.
8.4.1 Sum-type binning
This procedure increases the sensor response in cases of low lighting. This action roughly makes the
pixel area grow of the binning factor (x2 or x4).
