Abstract:
1. An indicia reading terminal comprising: an image sensor integrated circuit having a two dimensional image sensor array, said two dimensional image sensor array including a plurality of pixels, said indicia reading terminal including a binning module for applying a function using image information values representative of light incident at a plurality of pixels of said image sensor array, said indicia reading terminal further including a windowing module for use in selectively addressing a subset of pixels of said image sensor array for read out of a windowed frame; an imaging lens for use in focusing an image of a target decodable indicia onto said two dimensional image sensor array; a hand held housing encapsulating said two dimensional image sensor array, said indicia reading terminal being operative for manual activation of a trigger signal by an operator; wherein said hand held indicia reading terminal is operative so that for a time that said trigger signal remains active, said hand held indicia reading terminal can process a succession of frames, said succession of frames including a binned frame, said succession of frames further including a windowed frame, the windowed frame having image data representing light incident at a group of pixels of said image sensor array, the group of pixels comprising less than 50% of a total number of pixels of said image sensor array, the windowed frame representing indicia within a defined area of a target substrate that is relatively smaller than a defined area within which indicia would be represented by a frame representing light incident on each pixel of said image sensor array; wherein said hand held indicia reading terminal is operative to process a frame of said succession of frames for attempting to decode for decodable indicia.
