Patent attributes
Methods and devices for reducing noise in an image may include receiving an in focus image and at least one out of focus image of a scene, wherein the out of focus image has a second value of at least one focus-related parameter offset from a first value of the at least one focus-related parameter used for the in focus image. The methods and devices may include estimating a noise model of noise in at least a section of the out of focus image, and determining at least one parameter value for a filter based on the noise model. The methods and devices may include generating a noise-reduced image by applying the filter with the at least one parameter value to the in focus image to reduce at least part of the noise from at least a corresponding section of the in focus image.
