Abstract
A method of forming an offset-corrected exposure image includes obtaining an initial exposure image and exposure metadata related to the initial exposure image. An intermediate offset-corrected exposure image is formed by obtaining one or more dark images associated with the initial exposure image and subtracting an averaged value of the one or more dark images from the initial exposure image. The offset-corrected exposure image is obtained by combining an offset adjustment map with the intermediate offset-corrected exposure image.
