Method and apparatus for generating an all-in-focus image

摘要

Techniques are described for generating an all-in focus image with a capability to refocus. One example includes obtaining a first depth map associated with a plurality of captured images of a scene. The plurality of captured images may include images having different focal lengths. The method further includes obtaining a second depth map associated with the plurality of captured images, generating a composite image showing different portions of the scene in focus (based on the plurality of captured images and the first depth map), and generating a refocused image showing a selected portion of the scene in focus (based on the composite image and the second depth map).

主权项

1. A method for image processing, comprising:
obtaining a plurality of images of a scene at differing focal lengths, wherein each image shows differing portions of the scene in focus; obtaining a first depth map associated with the plurality of images; obtaining a second depth map associated with the plurality of images, wherein the first depth map corresponds to a first neighborhood size and the second depth map corresponds to a second neighborhood size; generating a composite image showing two or more portions of the scene in focus, based on the plurality of images and the first depth map; and generating a refocused image showing a selected portion of the scene in focus, based on the composite image and the second depth map.
