Setting the Exposure Time
This section describes how the exposure time can be adjusted manually by setting the value of the
ExposureTime parameter. The camera also has an exposure auto function that can automatically
adjust the exposure time.
You can use the Basler pylon API to set the ExposureTime parameter value from within your
application software. The following code snippet illustrates using the API to set the parameter value:
// Set the exposure time to 40.0 µs
camera.ExposureTime.SetValue(40.0);
By default, the exposure auto function is enabled. Manual adjustment of the
exposure time will not work.
Set the ExposureAuto parameter to Off before making any manual adjustments.
For more information about the exposure auto function, see Section 11.11.4 on
.

Table 24: Minimum and Maximum Allowed Exposure Time Setting and Increment
Depending on the camera’s sensor and the frame rate, the effective exposure time
may vary from the exposure time set. The variation is normally in the range of
microseconds, but if a very short exposure time is set, this should be taken into
account.
