Camera.Timing.Framerate.Set
Syntax
uEye.TimingFramerate.Set(double f64Value, out double f64NewValue)
uEye.TimingFramerate.Set(double f64Value)
Description
Using this method, you can set the sensor frame rate in freerun mode (live mode). Since this value depends on the sensor timing, the exposure time actually used may slightly deviate from the value set here. After you have called the method, the actual frame rate is returned through the f64NewValue parameter.
If the frame rate is set too high, it might not be possible to transfer every single frame. In this case, the effective frame rate may vary from the set value.
For minimum and maximum frame rates as well as other sensor-based dependencies, please refer to "Camera and sensor data" chapter in the uEye manual.
|
Newer driver versions sometimes allow an extended value range for the frame rate setting. We recommend to query the value range every time and set the frame rate explicitly. Changes to the frame rate affect the value ranges of the exposure time. After executing Set(), calling Exposure is recommended in order to keep the defined camera settings. |
|
The use of the following classes/methods will affect the frame rate: •AOI (if the image size is changed) Changes made to the window size or the read-out timing (pixel clock frequency) also affect the defined frame rate. For this reason, you need to call Set() again after such changes. |
|
To be able to set the default frame rate, you have to set a pixel clock equal to or higher than the default pixel clock. |
Parameter
f64Value |
Desired frame rate in frames per second (fps) |
|---|---|
f64NewValue |
Returns the frame rate actually set. |
