INT is_SetFlashStrobe (HIDS hCam, INT nMode, INT nLine)
Description
Attention
This function is obsolete and should not be used anymore. We recommend to use the
instead (see also Obsolete functions
is_SetFlashStrobe() controls the DCx Camera's digital outputs and defines the flash strobe behavior. The
digital outputs can be used in both freerun mode and trigger mode. You can synchronize the output level to the
exposure time or set it statically.
For details on flash timing, see the
Notes
Duration and Trigger Delay
You can set the flash duration and flash delay using the
is_GetGlobalFlashDelays()
current timing settings.
Accuracy of Flash Synchronization
The following parameters have an influence on the camera's internal timing:
Image geometry (CMOS and CCD sensors)
144
Pixel clock (CMOS and CCD sensors)
294
Exposure time (CCD sensors)
216
If you change any of these parameters, you will have to set the flash duration and flash delay parameters once
again.
