Determining the Frame Readout Time Using Basler Pylon
You can determine the frame readout time by reading the value of the Readout Time Abs parameter.
The parameter indicates what the readout time will be in microseconds given the camera’s current
settings. You can read the Readout Time Abs parameter value from within your application software
by using the Basler pylon API.
The following code snippet illustrates using the API to get the parameter value:
double ReadoutTime = Camera.ReadoutTimeAbs.GetValue( );
You can also use the Basler pylon Viewer application to easily get the parameter value.
For more information about the pylon API and the pylon Viewer, see Section 3.1 on page 19.
Determining the Frame Readout Time Using Direct Register Access
To determine the frame readout time via direct register access:
 Read the value of the Readout Time Raw register.
A value in a raw register is simply an integer value with no units. To determine what the actual
exposure time will be, you must multiply the value in the raw register by the camera’s time base.
The time base on ace cameras is 1 µs.
For example, if you read the Readout Time Raw register value as 18000, the frame readout time
would be 18000 µs (18000 x 1 µs = 18000 µs).
Note that the frame transmission time is always equal to the frame readout time.
