Syntax
INT is_SetOptimalCameraTiming (HIDS hCam, INT Mode, INT Timeout, INT* pMaxPxlClk, double* pMaxFrameRate)
Description
|
IMPORTANT! The function for determining the optimal pixel clock cannot be used for uEye cameras when the internal image memory is enabled. This function is currently not supported by the following camera models: •UI-1007XS |
Using is_SetOptimalCameraTiming(), you can determine the highest possible pixel clock frequency (at full resolution) for the current configuration. This function sets the pixel clock for which no transfer errors will occur during the timeout period. Moreover, it returns the highest frame rate available for this pixel clock frequency.
is_SetOptimalCameraTiming() can only be executed in free-run mode (is_CaptureVideo()). If the return value is ≠ IS_SUCCESS, no clock setting will be made.
The function should be executed in a separate thread and run in the background to allow for the computational load caused by additional color conversions, etc. Otherwise, it will not able to return the optimum values.
Changes to the image geometry or pixel clock affect the value ranges of the frame rate and exposure time. After executing is_SetOptimalCameraTiming(), calling the following functions is recommended in order to keep the defined camera settings:
•If you are using the uEye camera's flash function: is_IO()
•For starting the image catpture in freerun mode: is_CaptureVideo()
Input parameters
hCam |
Camera handle |
Timeout |
Sets the period (in milliseconds) during which no transfer error may occur. The adjustable range is between 4 and 20 seconds. The higher the value you set for this parameter, the more stable the determined pixel clock value will be. This, in turn, increases the runtime of the function correspondingly. |
pMaxPxlClk |
Returns the maximum pixel clock frequency (in MHz). |
pMaxFrameRate |
Returns the maximum frame rate (in fps). |
Return values
IS_AUTO_EXPOSURE_RUNNING |
This setting cannot be changed while automatic exposure time control is enabled. |
IS_INVALID_IMAGE_SIZE |
Invalid image size This value is returned if e.g. the function is called with active binning or subsampling |
IS_INVALID_MODE |
Camera is in standby mode, function not allowed |
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_NOT_SUPPORTED |
The camera model used here does not support this function or setting. |
IS_TRIGGER_ACTIVATED |
The function cannot be used because the camera is waiting for a trigger signal. |
