GetFrameTimeRange

Syntax

LONG GetFrameTimeRange( DOUBLE* minFps, DOUBLE* maxFps, DOUBLE* intervall)

Description

Using GetFrameTimeRange(), you can read out the frame rate settings which are available for the current pixel clock setting. The returned values indicate the minimum and maximum frame duration in seconds. You can set the frame duration between min and max in increments defined by the intervall parameter.

The following applies:

fpsmin= 1/max

fpsmax= 1/min

fpsn= 1/(min + n * intervall)

Hinweis

The use of the following functions will affect the frame duration:

•SetPixelClock()

•SetOptimalCameraTiming()

•SetAOI() (if the image size is changed)

•SetSubSampling()

•SetBinning()

Changes made to the window size, the frame rate or the read-out timing (pixel clock frequency) also affect the defined frame duration. For this reason, you need to call is_GetFrameTimeRange() again after such changes.

Parameters

minFPS	Returns the minimum available frame duration.
maxFPS	Returns the maximum available frame duration.
intervall	Returns the increment you can use to change the frame duration.

Return values

IS_SUCCESS	Function executed successfully
IS_NO_SUCCESS	General error message
