Optical scanner employing smart pixel array |
摘要 |
A scanner for reading encoded indicia having parts of different reflectivity to incident radiation comprises a detector for detecting incident radiation reflected thereto by the indicia, the detector comprising an array of pixels generating output signals indicative of the reflected radiation incident thereon. The array has signal processing circuits therein in electrical communication with the pixels and receiving the pixel output signals and generating signal processing circuit output signals. A decoder decodes the encoding in the indicia by processing selective of the signal processing circuit output signals. Selection of the signal processing circuit output signals may be in accordance with edge definition content thereof.
