Ordering number : EN*4982A  
CMOS LSI  
LC82101  
Image Processing Circuit  
for FAX, Copier, and OCR Products  
Preliminary  
Overview  
• Halftone processing  
Structural dithering (64 levels), settable dithering  
threshold level  
Error diffusion technique (64 levels)  
• Image reduction (thinning, fine black line retaining, fine  
white line retaining)  
• Single-voltage 5 V supply and low power due to CMOS  
process fabrication  
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.  
Package Dimensions  
unit: mm  
3174-QFP80E  
[LC82101]  
Features  
• Number of pixels processed  
2048 pixels/line (64 KB memory, white correction only)  
4096 pixels/line (256 KB memory, both white and black  
correction)  
8192 pixels/line (256 KB memory, white correction  
only)  
• Processing speed  
500 ns/pixel maximum (The processing time for 1 pixel  
is 16/SYSCLK.)  
SANYO: QIP80E  
• Supports medium speed products with a single external  
memory chip  
100 ns access time memory allows 800 ns/pixel  
processing, and 60 ns access time memory allows  
500 ns/pixel processing.  
• AGC (The A/D converter high-level reference voltage is  
varied from 1.2 to 4.2 V in 0.2 V steps.)  
• Built-in 8-bit A/D converter (includes a sensor signal  
delay adjustment function)  
• Sensor drive circuit (supports CCD and all CIS types)  
• Digital clamp (single-point clamp, even/odd clamp)  
• Distortion correction (white correction, black correction,  
full-pixel correction)  
• Gamma correction (supports user-defined curves)  
• Image area separation (text, photographs, halftone)  
• Simple binary-conversion processing (fixed threshold  
level, density-adaptive threshold level)
