Ynjiun P Wang, Angi Ye: Sub-pixel dataform reader with dynamic noise margins. Metanetics Corporation, Benesch Friedlander Coplan & Aronoff, November 9, 1999: US05979763 (265 worldwide citation)

Sub-pixel processing of image data representing a dataform, such as a 2D bar code, enables reading of dataforms including more data/smaller elements, without costly increases in sensor and memory capacity. Whole pixel processing is employed for pixel-per-element resolutions of two or better. Sub-pix ...

Ynjiun P Wang, Angi Ye: Anti-hand-jittering dataform readers and methods. Metanetics Corporation, Kenneth P Robinson, November 25, 1997: US05691773 (67 worldwide citation)

Dataform readers using two-dimensional sensor array cameras provide image frames comprising successive first and second fields of image data. In hand-held operation, hand jitter results in image offset causing registration errors between fields. Resolution and decoding performance are enhanced by de ...
