摘要
A color-reproducing contact image sensing (CORCIS) system that eliminates the use of multiple arrays of photodetectors with separate color filters and which permits the use of any of various signal- processing improvements such as voltage pickoff, transducer gain and correlated double sample and hold processing. The device operates by sequentially illuminating the colored object to be reproduced by primary color illumination means, with each illumination transferring in parallel the appropriate color response to a readout register for sequential readout. The sample and hold, and the parallel transfer operation, allow the CORCIS system to be able to read out signal while the detector array is integrating the next color signal, thus improving the sensitivity.
