Canon says hold that blink

Trying to capture a picture perfect moment can be tricky – how many shots of people have you seen that involved somebody blinking? Canon is currently working on a spanking new digital camera software that will take a photo only when nobody blinks. That’s right, you won’t end up wasting shots anymore, although I suspect this will make photo taking a little bit longer since everybody has different blinking frequencies. I wonder what kind of algorithm is applied to calculate the chances of catching everybody with their eyes wide open. Will the software be able to handle large groups of people, say, a hundred?
