DCU cameras only!
Syntax
INT is_SetFlashStrobe (HIDS hCam, INT nMode, INT nLine)
Description
is_SetFlashStrobe()
enables / disables the flash output of the DCU camera. In addition, you can
set the active level (high or low). By default, the strobe is set to high-active. Alternatively, the strobe
output can be used statically as a digital output.
You can set the duration of the flash and the flash delay using the
is_SetFlashDelay()
function. In order to obtain precise synchronization of flash output and exposure time, we
recommend to use the values returned by the
is_GetGlobalFlashDelays()
function for flash
delay and duration.
When you are using the DCU camera's flash function, you need to re-enable the flash (i.e. disable
and then activate it again) whenever you change the pixel clock setting or horizontal image
geometry. This is necessary to newly synchronise the internal timing settings of the flash output
with the start of sensor exposure.
