Abstract:
Provided are computer-implemented systems and methods for image correction after combining images from multiple cameras. While combining multiple images may significantly enhance image quality without a need for a longer focal length lens, combined images may have some perspective distortion caused by different imaging angles used by different cameras. For example, when two cameras provided on the same device are used to capture images of a face and these images are combined by cross-fading, a combined image may have an unnaturally widened center portion. Specifically, proportions of nose and ears may be distorted resulting in a wider nose and generally a wider face. The combined image may be compressed either uniformly or non-uniformly (e. g. , more compression in the center) to yield a processed image with more realistic and/or natural proportions. The compression ratio and/or compression distribution may depend on imaging angles, various distances, and other factors described herein.
