METHOD OF DECODING BARCODE WITH IMAGING SCANNER HAVING MULTIPLE OBJECT SENSORS

摘要

A method of decoding using an imaging scanner having multiple object sensors each associated with an object field of view. The method includes determining a moving direction of the object using at least two of the multiple object sensors. The moving direction of the object points from a first side to a second side of the imaging scanner. The method includes detecting whether a new object is presence with the object sensor located on the first side of the imaging scanner, and upon detecting the presence of the new object within the object field of view of the object sensor located on the first side of the imaging scanner, capturing an image of the new object in memory with the solid-state imager.

1. A method of decoding using an imaging scanner having a solid-state imager and having multiple object sensors each associated with an object field of view, the method comprising:
detecting whether an object is presence within any one of the object field of views; upon detecting the presence of the object within any one of the object field of views, activating one or more illumination light sources toward the object; detecting light reflected from the object with the solid-state imager to capture an image of the object in memory; processing the image captured by the solid-state imager to decode a barcode in the image captured; determining a moving direction of the object using at least two of the multiple object sensors, wherein the moving direction of the object points from a first side to a second side of the imaging scanner; upon successful decoding of the barcode in the image captured, detecting whether a new object is presence with the object sensor located on the first side of the imaging scanner; upon detecting the presence of the new object within the object field of view of the object sensor located on the first side of the imaging scanner, activating one or more illumination light sources toward the new object; detecting light reflected from the new object with the solid-state imager to capture an image of the new object in memory; and processing the image of the new object to decode any barcode on the new object.
