Description
Attention
This function is obsolete and should not be used anymore. We recommend to use the
instead (see also Obsolete functions
is_SetFlashDelay() sets a delay for driving the flash output. In addition, you can specify the flash duration.
This allows the implementation of a global flash functionality which exposes all rows of a
In addition, it is possible, for a camera with
start time of the exposure window.

Note
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.
