Syntax
INT is_SetFlashDelay (HIDS hCam, ULONG ulDelay, ULONG ulDuration)
Description
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
rolling shutter sensor. In addition, it is possible, for a camera with global shutter sensors, to set the
flash start in free-run mode to the start time of the exposure window.
For further information, please refer to the Digital Output (Flash/Strobe) and Shutter Methods
chapters.
