Apple Patented Tilt & Perspective Correction Technology for iPhone Camera

Apple has just filed a patent application with the U.S Patent & Trademark for an application to build in the iPhone various sensors to automatically correct tilt and perspective distortion when capturing photos. The correction will occur while shooting and can also be stored along with the photo for later correction.

The automatic correction measures distortion by combining an orientation measurement, accelerometer data and a “distance measurement device” such an ultrasonic device. The patent statement explained that, “In some embodiments, the method may include reading an orientation measurement associated with a relative position of an image capture device with respect to an object, determining if the orientation measurement is less than a threshold, and in the event that the orientation measurement is less than the threshold, correcting an image obtained by the image capture device.”

The application will be useful as it helps users to steady mobile devices when capturing photos. As stated in the patent file, the application may also be added with a “sophisticated image processing software”. appleinsider.com
