7.10.2 Flash Window Signal

Cameras with a rolling shutter imaging sensor (e.g., acA2500-14 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 70 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 7.7.2 on page 113.

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.
