[SUGGESTION] Lens correction - barrel distortion removal

Please add lens distortion filter (barrel distortion removal) to application. It is easy to implement in realtime.

Without correction it looks like this:

With correction on phone side in realtime it looks that:

Hey, Kyokushin!
I did some research on this topic, and i tried to remove the lens distortion with After Effects, but my mid-end computer was processing the 7 minute video about 2 hours, so I think that it's not possible to remove the distortion in real time (unless you own a server farm), because your controlling device just doesn't have enough performance.
There's a little scale below to make things clear!
1: Performance of a high end Android tablet
2: Performance of a high end PC
3: The performance needed to remove the distortion in realtime
