General Description
The PI201M-A4 is a CIS module. It is a long contact image sensor, using MOS image
sensor technology for high-speed performance and high sensitivity. The PI201M-A4 is
suitable for scanning A4 size (216 mm) documents with 8 dots per millimeter resolution.
Applications include document scanners, mark readers, and other office automation
equipment.
Functional Description
The PI201M-4A imaging array consists of
27 sensors that are cascaded to provide
1728 photo-detectors with their associated
multiplex switches, and a digital shift
register that controls its sequential
readout. Mounted in the module is one-to-
one graded indexed micro lens array that
focuses the scanned documents to image
onto its sensing plane. The on-
board amplifier processes the video signal
to produce a sequential stream of video at
the video output pin of the PI201M-A4
module.
