Google patents image sharpening that uses depth to fix blur

This filing describes a method for sharpening blurry photos by first measuring how far away different parts of the scene are. It then picks a specific sharpening tool for each area based on that distance, rather than using one setting for the whole picture.

Why it mattersIt could lead to sharper photos in tricky lighting or motion scenarios by treating near and far objects differently.

In the filing’s own words

A method includes receiving, from a sensor, an image. The method also includes determining, based on the image, at least one pixel area identified to contain a region of interest within the image. The method additionally includes determining depth information for the at least one pixel area. The method further includes based on the depth information for the at least one pixel area, selecting at least one deblur model from a plurality of deblur models to apply to the at least one pixel area. The method also includes applying the selected at least one deblur model to determine a deblurred image comprising the at least one pixel area, where the at least one pixel area is deblurred based on the depth information.

What exactly they claim (claim 1)

1. A method comprising: receiving, from a sensor, an image; determining, based on the image, at least one pixel area identified to contain a region of interest within the image; determining depth information for the at least one pixel area; based on the depth information for the at least one pixel area, selecting at least one deblur model from a plurality of deblur models to apply to the at least one pixel area; and applying the selected at least one deblur model to determine a deblurred image comprising the at least one pixel area, wherein the at least one pixel area is deblurred based on the depth information.
