Binning

Binning is the com bining of tw o or m ore im age sensor p ixels to form  a new  com bined  p ix el. A binned
im age u sing the sam e exp osu re settings as a non -binned  im age w ill show  an im p roved  signal-to-noise
ratio, red u ced  scanning tim es (d u e to low er sp atial resolu tion) and  save as a sm aller im age file size
com p ared  w ith a non -binned  im age, at the exp ense of low er im age resolu tion.

In 2 x 2 binning, 4 p hysical p ixels on the sensor are com bined  into one im age p ixel. This op erating m od e
is id eal for ap p lications that requ ire faster acqu isition and  p rocessing tim es and  requ ire greater s ign al
