4.3.4 Increasing Sensitivity with Binning

Binning increases the cam era's light sensitivity by d ecreasing horizontal and / or vertical
resolu tion—the charge collected by ad jacent pixels is ad d ed together. Binning is also
u sefu l for increasing fram e rate (vertical binning) or increasing the pixel pitch. For
exam ple, if you set you r vertical binning to 2 and you r horizontal binning to 2, you r pixel
size increases from 7µm x 7µm (no binning) to 14µm x 14µm (2x2 binning).

Increases the horizontal pixel pitch and light sen sitivity by
d ecreasing horizontal resolution. The am ount of d ata being sent
from the cam era is red uced by the horizontal binning factor.
Different fram egrabber files are need ed for d ifferent horizontal
binning factors.

If you are using horizontal binning, the m in, m ax, and m ean
statistics generated by the
second pixel (or valid d ata) only (e.g., if sbh 2, every second
pixel).

For optim al flat field correction, you should rerun the ccp and
ccf com m and s after changing binning values.

Changing binning values d oes not autom atically alter gain,
fram e rate generation, or other functions of the cam era.
