3. Halftone process

•

The data is converted to six-bit (0 - 63) for halftone processing. In addi-
tion, if error diffusion was selected, each element is corrected using the
differences between it and the surrounding elements. This process re-
duces the differences in contrast between light and dark areas of a half-
tone image.

•

Edge enhancement is done - As a result of the edge detection, if the ele-
ment is on a boundary, the element goes directly to white or black, with-
out thresholding (see below).

•

The data is thresholded. Each pixel is compared with the corresponding
element in a dither matrix or using error diffusion. The resulting data is
one-bit (0 or 1).

3. Video Processing Parameters

Some of the parameters used for digital image processing can be changed
by RAM addresses. See section 5-11-4 for details.

1. Contrast

RAM addresses 8003FD to 80040E

2. Image processing parameters

RAM addresses 80040F to 800426
