Abstract:
1. An optical indicia reading system configured to capture and process an image of decodable indicia, said optical indicia reading system comprising: a decodable indicia; a first image sensor having a first field of view (FOV) fully including the decodable indicia; a second image sensor having a second FOV, the second FOV fully including the decodable indicia, wherein a majority of an area delimited by the second FOV overlaps with a majority of an area delimited by the first FOV; at least one analog-to-digital converter configured to convert a first analog signal read out of said first image sensor into a first digital signal, said analog-to-digital converter further configured to convert a second analog signal read out of said second image sensor into a second digital signal; a microprocessor; a hand held housing encapsulating said first image sensor and said second image sensor; wherein said microprocessor is configured to construct a first image including a representation of a full spatial area of said decodable indicia by processing said first digital signal, said first image having a first resolution insufficient to decode said decodable indicia; wherein said microprocessor is further configured to construct a second image including a representation of a full spatial area of said decodable indicia by processing said second digital signal, said second image having a second resolution insufficient to decode said decodable indicia; wherein said microprocessor is further configured to construct a third image including a representation of a full spatial area of said decodable indicia by processing said first image and said second image, said third image having a third resolution sufficient to decode said decodable indicia, said third resolution being of sub-pixel resolution relative to said first resolution, said third resolution being of sub-pixel resolution relative to said second resolution; wherein said microprocessor is further configured to output a decoded message data corresponding to said decodable indicia by processing the third image.
