Syntax
INT is_GetGlobalFlashDelays (HIDS hCam,
ULONG* pulDelay,
ULONG* pulDuration)
Description
Rolling shutter cameras:
Using
is_GetGlobalFlashDelays()
, you can determine the times required to implement a global
flash function for rolling shutter cameras. This way, a rolling shutter camera can also be used as a
global shutter camera provided that no ambient light falls on the sensor outside the flash period.
If the exposure time is set too short so that no global flash operation is possible, the function
returns
IS_NO_SUCCESS
.
To use a rolling shutter camera with the Global Start function, call the is_SetGlobalShutter()
function before is_GetGlobalFlashDelays(). Otherwise, incorrect values will be returned for
Delay
and
Duration
.
Global shutter cameras:
In freerun mode, the exposure of global shutter cameras is delayed if the exposure time is not set to
the maximum value.
is_GetGlobalFlashDelays()
determines the required delay in order to
synchronise exposure and flash operation. In triggered mode, the return values for delay and flash
duration are 0, since no delay is necessary before exposure starts.
For further information, please refer to the Camera Basics: Shutter Methods
chapter.
