Description



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

Description

The LC82102 and LC82102W convert analog video signals from CCD or contact image sensors to highquality binary video data. The LC82102/W converts the input analog data to multi-valued data and uses twodimensional 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.
