Method of decoding barcode with imaging scanner having multiple object sensors

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, and capturing an image of the object in memory by detecting light reflected from the object with the solid-state imager;
• 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;
• 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, and capturing an image of the new object in memory by detecting light reflected from the new object with the solid-state imager.

An imaging scanner comprising:

• a portable housing configured for standing on top of a flat surface with a vertical axis of the portable housing perpendicular to the flat surface;
• a window on the portable housing;
• a primary mirror generally facing the window and titled with respect to the vertical axis of the portable housing by an angle between 40 to 50 degrees;
• a solid-state imager having an array of photosensitive elements on a substrate that is either perpendicular to the vertical axis of the portable housing or parallel to the vertical axis of the portable housing, wherein the solid-state imager is operative to capture light from a target object within a field of view after said light from the target object passes through the window and gets reflected by the primary mirror;
• multiple object sensors each associated with an object field of view, wherein each object sensor includes an infrared light emitting diode and a photodetector;
• and
• a controller operative to determine a moving direction of an 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.
