5-2 Pixel Binning Mode
Binning read-out can be used to obtain an image of lower resolution for full field of view. It has advantage on frame
rate than using digital scaling, and on signal-to-noise ratio than using sub-sampling. See Binning Capability Registers,
for detail of available configurations.
The following diagram describes on 2x2 averaged binning operations. Pixels of two adjacent rows and columns are
averaged, and read out as one output pixel.

For explanation, represent individual pixels with it's ) - for example, The Red
pixel in the lower left corner is expressed as R (0, 0).
By performing 2x2 binning, R (0, 0) after binning is obtained by the following equation.
R (0, 0) after binning = ( {R (0, 0) + R (0, 2)} /2 + {R (2,0) + R (2,2)} /2 ) / 2
And, the total number of output pixels is reduced to 1/4 of the original pixel array.
