Preliminary
CMOS LSI
LC82102, LC82102W
Image-Processing LSI
for Fax, Copier and OCR Products
Overview
The LC82102 and LC82102W convert analog video
signals from CCD or contact image sensors to high-
quality binary video data. The LC82102/W converts the
input analog data to multi-valued data and uses two-
dimensional filtering and an error diffusion technique that
produces high-quality images to produce a two-valued
image. Finally, the LC82102 reduces the image in the
main and subsidiary scan directions. The LC82102
requires absolutely no external memory since it limits the
number of pixels processed to 2040 per line. This LSI can
implement the image processing used by FAX, copier and
OCR products.
Features
• Number of pixels processed: 2040 pixels/line
• Processing speed: 500 ns/pixel maximum (when the
CLKIN input frequency is 32 MHz)
• Built-in 8-bit A/D converter (includes a sensor signal
delay adjustment function)
• Built-in 6-bit D/A converter for setting the A/D
converter high reference potential
• Sensor drive circuit (supports CCD and all CIS types)
• Digital clamp (single-point clamp, even/odd clamp)
• Distortion correction (white correction: 8-pixel
averaging correction, black correction: black correction
subtraction data setting)
• Gamma correction (supports user-defined curves)
• Simple binary-conversion processing (fixed threshold
level, density-adaptive threshold level)
• Intermediate processing error diffusion (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
