Transaction point workstation for imaging sheet target and sheet target imaging method

摘要

A workstation processes a product by imaging an indicium associated with the product in a transaction, and images a sheet-like target associated with the transaction. A window is supported in a window plane in contact with the target during target imaging. An imaging assembly captures light from the indicia during product processing, and from the target during target imaging, over a plurality of fields of view extending along different directions through the window. Each field bounds an area in the window plane that is smaller than the entire target. At least one pair of the fields partially overlaps each other in the window plane. The fields overlap contiguous portions of the target during target imaging. The light from the contiguous portions is captured by the imaging assembly as a plurality of target images. A controller compiles the target images into a single output image indicative of the target.
