Abstract:
A method for processing a plurality of digital image data from an analog/digital converter of an image information reading apparatus, comprising the steps of:predetermining a data format for an encoded byte, said encoded byte comprising an attribute field, and a counter field; logically dividing said plurality of digital image data into a plurality of image blocks; processing each of said plurality of image blocks in a sequential order by following the steps of: (a) reading a bit stream from said plurality of digital image data; (b) recording an attribute of said bit stream in an attribute field of an encoded byte for said bit stream; (c) setting a binary â€œ11â€  in a counter field of said encoded byte for said bit stream when said attribute of said encoded byte representing a high bit or a low bit, and executing a step of (e); (d) sequentially reading a bit stream from said plurality of digital image data into said counter field of said encoded byte for said bit stream when said attribute of said encoded byte is not a high bit nor a low bit; (e) continuously counting the number of bits having the same value of said bit stream from said plurality of digital image data until said counter field of said encoded byte is all â€œ1â€ s or until encountering a bit having an opposite value of said bit stream; (f) outputting said encoded byte when said counter is all â€œ1â€ s or when encountering a bit having an opposite value of said bit stream; and (g) repeating said step (a) to said step (f) until said plurality of digital image data has been completely encoded.
