Abstract 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. © 2007 Wiley Periodicals, Inc. Int J Imaging Syst Technol, 17, 123–131, 2007
