Intelligent image blending for panoramic photography

摘要

This disclosure pertains to devices, methods, and computer readable media for performing positional sensor-assisted panoramic photography techniques in handheld personal electronic devices. Generalized steps that may be used to carry out the panoramic photography techniques described herein include, but are not necessarily limited to: 1.) acquiring image data from the electronic device's image sensor; 2.) performing “motion filtering” on the acquired image data, e.g., using information returned from positional sensors of the electronic device to inform the processing of the image data; 3.) performing image registration between adjacent captured images; 4.) performing geometric corrections on captured image data, e.g., due to perspective changes and/or camera rotation about a non-center of perspective (COP) camera point; and 5.) “stitching” the captured images together to create the panoramic scene, e.g., blending the image data in the overlap area between adjacent captured images. The resultant stitched panoramic image may be cropped before final storage.

主权项

1. A method to generate a panoramic image, comprising:
obtaining a first image from an image sensor having a first region and a second region, the second region including a first representation of a face, the first image stored in a first memory; obtaining a second image from the image sensor having a third region and a fourth region, the third region including a second representation of the face, the second image stored in a second memory; aligning the first and second images so that the second and third regions overlap to generate an overlap region; masking an area corresponding to the first representation of the face in the overlap region to generate a mask region; blending the first and second images in the overlap region, except for the mask region, to generate a blended region; and generating a result image comprising the first region, the fourth region and the blended region wherein the area in the blended region corresponding to the mask region is replaced with the first representation of the face.
