Got a case of the shaky hands? If so, you’re going to appreciate what the folks over at Linkoping, Sweden have come up with. Some scientists at the Linkoping University recently launched DollyCam for the iPhone and iPad – an app that helps people with unsteady hands record professional-looking videos on their iOS devices.
Sometimes even if you have a steady hand, you still get amateurish-looking footage due to the rolling-shutter technology used in iOS devices. Professional video cameras use global-shutter cameras, rails and dollys for smooth camera movement – most of us amateur folk don’t have access to such equipment. DollyCam is designed to eliminate the need for all that. Here’s how it works:
DollyCam is based on leading research in computer vision. The unique algorithm uses three-dimensional data from the gyroscope and accelerometer sensors on the iOS device to correct tilted objects and remove wobble. A video stabilizer then adds smoothness and makes the movie stable. DollyCam is also adaptive and adjusts its parameters dynamically to the movie processed. The scientists have conducted a blind user study among students on campus. The study demonstrated that participants preferred DollyCam output to that of its competitors.
So if you’re looking for professional and smooth video from a cheap consumer camera – you could give DollyCam a try, it’s $2.99 from the Apple App Store. Watch the impressive demonstration video:
