露光制御と画像処理による2次元バーコードリーダーの高性能化

抄録

A cquisition of high S/N image is essential for im plementation of high - performance 2D bar - code reader . E xper imental results show that low S/N image s cause the readable rate to decrease even if out - of - focus image s are deblurred . An exposure control technique fo r acquiring high dynamic rage images is also presented .
