6.8.2 Flash Window Signal
Cameras with a rolling shutter imaging sensor (acA1920-25, acA2500-14, acA3800-14,
acA4600-10 models) can provide a flash window output signal to aid you in the use of flash lighting.
The flash window signal will go high when the flash window for each image acquisition opens and
will go low when the flash window closes. Figure 62 illustrates the flash window signal on a camera
with the shutter operating in the electronic rolling shutter mode.
For more information about the rolling shutter and the flash window, see Section 6.6.2 on page 114.
The flash window signal is also available on cameras with a global shutter imaging
sensor. On global shutter cameras, the flash window signal is simply the
equivalent of the exposure active signal.
