Apple Researching Perspective Correction for iPhone Camera

Posted on June 23, 2011 by

A new patent application from Apple titled “Image Capture Device Having Tilt and/or Perspective Correction” has been discovered. The patent details how Apple is trying to improve the iPhone’s camera capabilities by automatically compensating for tilt or perspective distortion during image capture or later.

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. In some embodiments, the apparatus may include an image sensor, a memory coupled to the image sensor, an orientation measurement device coupled to the image sensor, and a distance measurement device coupled to the image sensor, where the image data may be stored in the memory along with a measurement from the accelerometer and along with a measurement from the distance measurement device.
