With random timing, you're more likely to get one period that's long enough for the auto-exposure to correct it and see the face. Autoexposure takes time because it has to use a feedback loop to search for the correct exposure, so if the brightness changes fast enough, it can't keep up.
- dylan604 4y agoyou set a maximum on period so that doesn't happen. if you develop something with a known pattern, that can be programed in to be countered. hence my example of Macrovision. randomizing the values means it is much harder to counter.
