1. A scanner device comprising:

  • a plurality of image sensor arrays, wherein each image sensor array of the plurality of image sensor arrays is configured to acquire a corresponding sequence of analog image slices such that a plurality of corresponding sequences of analog image slices are acquired by the plurality of image sensor arrays, wherein(i) each one of the plurality of corresponding sequences of analog image slices is concurrently acquired, and(ii) each one of the plurality of corresponding sequences of analog image slices represents a contiguous partial scan of a target medium by a corresponding image sensor array of the plurality of image sensor arrays;

    an analog front end component configured to (i) receive the plurality of sequences of analog image slices and (ii) convert the plurality of sequences of analog images slices into a corresponding plurality of sequences of digital image slices; and

    an image processing component configured to generate an image file representing the target medium scanned by the plurality of image sensor arrays based at least in part on the plurality of corresponding sequences of digital image slices,wherein the analog front end component is configured to convert, in parallel, analog image slices from at least two of the plurality of sequences of analog image slices.
