METHOD AND DEVICE FOR GENERATING MULTI -SITE MODULATING WEB POINT SIMULTANEOUSLY

Document Type and Number:

WIPO Patent Application WO/2008/040162

Kind Code:

A1

Abstract:

The present invention refers to a method and device for generating multi-site modulating web site simultaneously. The method can simultaneously process multi-neighboring pixels in same row in each time and produces multi-site web point; and meanwhile renews the error accumulation values of multi location of error row. The device of present invention thereof comprises error row memory, error row memory control circuit, error allocation/accumulation register file control circuit, and web point generating circuit.
