Part Name(s) : LC82103 SANYO
SANYO -> Panasonic
Description : IMAGE-PROCESSING LSI FOR Facsimile, Copier, and OCR Applications View

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. That multilevel data is converted to high-precision bi-level IMAGE that is produced by using two dimensional filtering, a IMAGE separation method, and an error diffusion technique. Finally the LC82103 is able to reduce the IMAGE in the horizontal and vertical directions, too. The LC82103 requires absolutely no external memory since it limits the number of pixels processed to 3072/line. This LSI can implement the IMAGE PROCESSING used by FAX, copier, and OCR applications.

IMAGE area separation (characters, photographs, screened halftone areas)
• Simple binary coding process (fixed threshold, brightness adaptive threshold)
• Intermediate PROCESSING error diffusion (64 levels)
• Multilevel IMAGE resolution conversion (1/2, 2/3, 3/2, 2/1)

Overview
The LC82101 converts an analog IMAGE signal from a CCD or contact sensor to high-quality binary IMAGE data. The LC82101 uses an internal 8-bit A/D converter FOR A/D conversion, and in addition to the orthodox dithering technique, also supports an error diffusion technique that allows an even higher quality IMAGE to be acquired. These techniques apply to the whole range of PROCESSING supported by the LC82101, including full-pixel distortion correction, gamma conversion FOR arbitrary gamma curves, IMAGE compression PROCESSING, two-dimensional filtering, halftone PROCESSING, and IMAGE separation PROCESSING to separate documents into text, photograph, and halftone regions. Thus this LSI implements the IMAGE PROCESSING required by FAX, copier, and OCR systems.
