The Math Behind the Rolling Shutter Phenomenon

Excellent article.<p>I remember a few years back holding my mobile to the window to take a photo of the scenery while on a turbo prop passenger aircraft. I nearly had a heart attack when I noticed the propeller had stopped spinning!<p>Once I got over the initial shock and realised it was just rolling shutter on the phone screen I had a bunch of fun taking photos and videos of the effect in action. I&#x27;ll try and dig up one of the videos and post it here later.

Excellent article. Presumably at least part of the problem toward the end is that it&#x27;s based on the assumption the propellor moves at a constant speed; since the plane is not mid-flight, I would guess it&#x27;s probably accelerating.

Hi, I wrote this article about a year ago on my blog. Thanks for posting it!

Horizon, a game based on rolling shutter mechanics, but with geometry instead of pixels: <a href="http:&#x2F;&#x2F;omershapira.com&#x2F;portfolio&#x2F;horizon-a-4d-game&#x2F;" rel="nofollow">http:&#x2F;&#x2F;omershapira.com&#x2F;portfolio&#x2F;horizon-a-4d-game&#x2F;</a>

Wow. Terrific post- it is finding these kind of Gems that keeps me coming back to HN.

Here&#x27;s some information about a different type of shutter, and camera, and imaging technology: <a href="http:&#x2F;&#x2F;www.largeformatphotography.info&#x2F;forum&#x2F;showthread.php?31903-Jacques-Henri-Lartigue-and-his-camera" rel="nofollow">http:&#x2F;&#x2F;www.largeformatphotography.info&#x2F;forum&#x2F;showthread.php?...</a>
