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 amount of d ata being sent
from the camera is red uced by the horizontal binning factor.
Different framegrabber files are need ed for d ifferent horizontal
binning factors.
sbh m
m
Horizontal binning value. Available values are 1 (factory
setting, no binning) 2, 4, or 8.

If you are using horizontal binning, the min, max, and mean
statistics generated by the
second pixel (or valid d ata) only (e.g., if sbh 2, every second
pixel).

For optimal flat field correction, you should rerun the ccp and
ccf command s after changing binning values.

Changing binning values d oes not automatically alter gain,
frame rate generation, or other functions of the camera.

Pixel numbering remains unchanged for the roi, gl, gla,
dpc, gfc, sfc, gpc, and
for an explanation of pixel numbering and pixel start and stop
values w hen using a region of interest.
