A METHOD AND DEVICE FOR SENSOR LEVEL IMAGE DISTORTION ABATEMENT

摘要

A method, apparatus and software product for image processing using meta-data obtained by sampling the pixels or pixel regions of the image sensor array during the acquisition of the image. A performance enhancement is achieved by applying (non-linear) signal processing methods to the individual pixels or pixel regions of the array during image formation. The in-situ signal processing method described leverage knowledge of the image formation process to improve the signal quality of the pixels in the array. The present method, apparatus and software product may be used for post acquisition processing of the image or for processing during or immediately following acquisition of the image. Embodiments of the method mitigate noise, blur, and low contrast distortions in digital imaging arrays. Hardware and software embodiments are also presented.
