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:

The call of this function makes only sense in the freerun mode.

Hinweis

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

•is_PixelClock()

•is_SetOptimalCameraTiming()

•is_AOI() (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

hCam	Camera handle
min	Returns the minimum available frame duration.
max	Returns the maximum available frame duration.
intervall	Returns the increment you can use to change the frame duration.

Return values

IS_INVALID_CAMERA_HANDLE	Invalid camera handle
IS_INVALID_PARAMETER	One of the submitted parameters is outside the valid range or is not supported for this sensor or is not available in this mode.
IS_NO_SUCCESS	General error message
IS_SUCCESS	Function executed successfully
