A New Image Sharpening Approach for Single-Sensor Digital Cameras

摘要

This article introduces a new image sharpening approach suitable for single-sensor digital cameras equipped with a Bayer color filter array (CFA). The proposed solution firstly enhances the structural content of the captured CFA image data. Subsequent demosaicking of the enhanced CFA image data produces a visually pleasing full-color image which is noticeably sharper compared to the output of the traditional imaging pipeline. Results reported in this work suggest a three-fold processing cost reduction when the new approach is followed.
