We have developed a new contact-type color image sensor for personal use. Three color light emitted diodes are used, for illuminating source of document. The photodiode MOS image sensor chips are used for the photodetector element, which has superior linearity characteristic. It scans an A-size document in 25 seconds at 300 dots per inch. This color image sensor is compact and very low power, so its is most suitable to sheetfed color scanner.
