IMAGE PROCESSING

16 February 2000

Error Diffusion

The error diffusion process reduces the difference in contrast between light and

dark areas of a halftone image. Each pixel is corrected using the difference

between it and the surrounding pixels. The corrected pixels are then compared with

a matrix table.

Binary Picture Processing

Each video signal level is converted from 8-bit to 1-bit (black and white image data)

in accordance with a threshold value.

White/Black Conversion

Inverts the image (converts from white to black and vice versa).

After video processing, the data goes to the host computer through the memory

and SCSI controllers.
