DISPOSITIF ET PROCEDE POUR FOURNIR UN ZOOM NUMERIQUE DE RESOLUTION AMELIOREE DANS UN DISPOSITIF IMAGEUR ELECTRONIQUE PORTATIF

摘要

A portable electronic imaging device, in performing digital zoom, exploits barrel distortion in the original digital image to produce higher quality digitally zoomed images than can be obtained by simple cropping and rescaling. Such a portable electronic imaging device may be implemented using a moderately wide-angle lens of fixed focal length.
