Line Acquisition Modes
Basler sprint Mono Cameras 57
3.6 Line Averaging Acquisition Mode
When the line averaging acquisition mode is active, each time a line acquisition is triggered, the
camera will expose both line A and line B. When acquisition is complete (i.e., exposure is finished),
the pixel values from line A and from B will be averaged in the following manner:
 The value for pixel 1 in line A will be added to the value for pixel 1 in line B and the total will be
divided by 2 (and rounded up if necessary).
 The value for pixel 2 in line A will be added to the value for pixel 2 in line B and the total will be
divided by 2 (and rounded up if necessary).
 The value for pixel 3 in line A will be added to the value for pixel 3 in line B and the total will be
divided by 2 (and rounded up if necessary).
 And so on
The averaged values will then be transmitted from the camera as though they were from a single
line.
The pixels in each line of the sensor are 10 µm (H) x 10 µm (V). So when you are using line
averaging, you are getting the same aspect ratio as a single line sensor that is 10 µm (H) x 20 µm
(V).
Setting the Camera for Line Averaging Acquisition Mode
You can enable the line averaging acquisition mode by using the Camera Configuration Tool Plus
(CCT+) or by using binary write commands from within your own application to set the camera’s
control and status registers (CSRs).
Note that to enable line averaging, you must set a combination of two camera parameters. First,
you must set the Line Acquisition Mode parameter to Averaging. Second, you must set the Line
Delay parameter to None. This combination of settings results in line averaging.
With the CCT+
With the CCT+ (see Section 7.1 on page 156), use the Line Acquisition Mode parameter in the
Output Mode parameters group to set the line acquisition mode to Line Averaging.
By Setting CSRs
To enable the line averaging acquisition mode, write the appropriate value to the Mode field of the
Line Acquisition Mode CSR (see page 167).
Section 7.2.2 on page 164 explains CSRs and Section 7.3.1 on page 197 explains using read/write
commands.
