Image capture device having tilt and/or perspective correction

摘要

Methods and apparatuses are disclosed to correct for tilt and/or perspective distortion in image capture devices. 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. 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.

主权项

1. A method comprising:
obtaining an orientation measurement representing a physical orientation of an image capture device during an image display operation, wherein a displayed image comprises data representative of a scene; identifying one or more straight edges in the data corresponding to straight edges in the scene; determining a difference based, at least in part, on the measured orientation of the image capture device and an orientation of at least one of the one or more straight edges in the data; and displaying a distortion indicator with the displayed image when the difference is less than a threshold value.
