In this example a region of interest is set to include pixels 4 to 9 and horizontal binning is set to 2. Because
pixel 3 is now included in the same data group as pixel 4, the region of interest will now include the data
from pixel 3. Also, pixel 10 is included in the same data group as pixel 9, so pixel 10 is now part of the
region of interest. To see how the region of interest start and stop values have been rounded, use the
command get roi.
Setting Horizontal Digital Binning
Purpose:
Increases the horizontal pixel pitch and light sensitivity by decreasing horizontal
resolution. The amount of data being sent from the camera is reduced by the horizontal
binning factor. Different frame grabber files are needed for different horizon tal binning
factors.
Syntax:
sdh m
Syntax Elements:
m
Horizontal digital binning value. Available values are 1 (factory setting, no binning)
2, or 4.
Notes:
If you are using horizontal binning, the min, max, and mean statistics generated by
the gl or gla command are for every second pixel (or valid data) only (e.g., if sbh
2, every second pixel).
For optimal flat field correction, you should rerun the ccf and cpa commands after
changing binning values.
Changing binning values does not automatically alter gain, external frame rate
generation, or other functions of the camera.
Pixel numbering remains unchanged for the roi, gl, gla, gfc , sfc , gpc, and spc
commands. Refer to Figure 19 for an explanation of pixel numbering and pixel start
and stop values when using a region of interest.
Command sbh set to default (1).
Example:
sdh 2
Setting Vertical Analog Binning
Syntax:
Increases the vertical pixel pitch and light sensitivity by decreasing vertical resolution.
Vertical analog binning is also useful for increasing frame rate in Area Mode. Vertical
binning in TDI Mode should only be used if your w eb‘s shaft encod er provid es a
reduced ratio of pulses to match web speed.
Syntax:
sbv i
Syntax Elements:
i
Vertical binning value.
Available values are 1 (factory setting, no binning), 2, or 4.
Notes:
For optimal flat field correction, you should rerun the ccf and cpa commands
after changing binning values.
Increasing the vertical binning decreases the maximum allowable line rate. For
internal exposure mode, sem 7, the frame is clipped to the maximum allowable
and the camera sends a warning. For external exposure mode, sem 3, a new
camera frame rate may be required to avoid ignored syncs.
Command sdv set to default (1).
Example:
