is_GetFrameTimeRange
Syntax
INT is_GetFrameTimeRange (HIDS hCam,
double* min, double* max, double* intervall)
Description
Using is_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:
fps
min
=
1
/
max
fps
max
=
1
/
min
fps
n
=
1
/
(min + n * interv all)
The use of the following functions will affect the frame duration:
is_SetPixelClock()
is_SetOptimalCameraTiming()
is_SetAOI() (if the image size is changed)
is_SetSubSampling()
is_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.
Input Parameters
Returns the minimum available frame duration.
Returns the maximum available frame duration.
Returns the increment you can use to change the frame duration.
Return Values
Function executed successfully
