SetFrameRate

Syntax

DOUBLE SetFrameRate (DOUBLE dFps)

Description

SetFrameRate() sets the number of frames/sec. the sensor shall work with. If the frame rate is set too high, frames may be lost due to USB bandwidth limitations.

It is not possible to adjust any value because of internal timing constraints. Therefore the return value of the function is the effective adjusted frame rate.

With changing the the timing readout (pixel clock and frame rate) the exposure time will change also. Therefore SetExposureTime() must be called again after the function SetFrameRate().

Achtung

Changes to the frame rate affect the value ranges of the exposure time. After executing SetFrameRate, calling the following functions is recommended in order to keep the defined camera settings:

•SetExposureTime()

•If you are using the uEye's flash function: SetFlashStrobe()

Hinweis

The minimum and maximum values for the frame rate are dependent on the different types of camera models. Please refer to the uEye manual and the model related hardware manuals for more details.

Parameters

dFps	Frame rate in frames per second.

Return values

Current frame rate
IS_NO_SUCCESS	General error message
