Abstract
Binary image data is converted to CCITT standardized coded data by utilizing two barrel shift registers for selecting a window of image data from a reference line and from a coding line, two color changing detectors for converting the image data in a window to color changing codes, and one specially designed state machine for generating facsimile coded data from those color changing codes. The state machine operates on color change location data for the selected window to generate intermediate codes. The intermediate codes are then translated to an output format such as the CCITT standard.
