Ordering number : EN*5402 CMOS LSI LC82103 Image-Processing LSI for Facsimile, Copier, and OCR Applications Preliminaly Overview The LC82103 converts the analog video signal from the CCD contact image sensor into high-precision binary image data. The LC82103 includes an 8-bit A/D converter and two 6-bit D/A converters. The 6-bit D/A converters are used for setting reference potential (high and low) of the 8-bit A/D converter. The LC82103 converts the input analog data to high precision multilevel data, that is produced by all pixel shading correction process, multilevel image resolution converting process, and γ correction process of user defined curves.
