Sensor Readout Mode

The acA640-750um/uc, acA800-510um/uc, acA1300-200um/uc, acA1920-150um/uc, and
acA2500-60uc cameras are equipped with sensors that allow to set the sensor readout mode. Two
modes are available, "normal" and "fast".
In fast sensor readout mode, the readout time for each line of pixels (the line readout time) is
shortened compared to the normal readout mode. As a consequence, the overall sensor readout
time is shortened. This allows you to increase the maximum frame rate compared to operation in
normal sensor readout mode. Note, however, that the image quality can deteriorate when using fast
sensor readout mode.
You can determine the readout time for a frame by checking the value of the camera's
SensorReadoutTime parameter (Section 6.9 on page 174).
Remember that you can further decrease the readout time for a frame by decreasing the ROI height
(see Section 6.6.1 on page 142).
Setting the Sensor Readout Mode
The following code snippet illustrates using the API to set and read the parameter values for the
Sensor Readout Mode (values: Normal, Fast):
// Set and read the sensor readout mode parameter value
camera.SensorReadoutMode.SetValue(SensorReadoutMode_SensorReadoutMode_Normal);
camera.SensorReadoutMode.SetValue(SensorReadoutMode_SensorReadoutMode_Fast);
SensorReadoutModeEnums e = camera.SensorReadoutMode.GetValue();
You can also use the Basler pylon Viewer application to easily set the parameter.
For more information about the pylon API and pylon Viewer, see Section 3.1 on page 61.
