Abstract
A scanner device includes an analog front-end component and an image processing component. The analog front-end is configured to receive, from a scan head, analog signals carrying analog image slices and provide compressed digital signals. The analog front-end component has a data compressor configured to compress digital image slices that correspond to the analog image slices digitized, wherein each analog image slice is comprised of a plurality of analog pixel values that represent a slice of the target medium. The image processing component has a data decompressor configured to (i) receive and decompress the compressed digital signals into digital signals, and (ii) generate an image file of a target medium based at least in part on the digital signals.
