PURPOSE:To form a color facsimile with low cost and having high performance tone, by applying at least one of primary and secondary dimensions coding for every bit of the same weight of each video element information, in a video cmpression system of facsimile. CONSTITUTION:When video element information required for the processing of deterioration picking and storing the input data is inputted with a CLK, inverting bit candidates 96, 97 for processing the secondary or primary dimension deterioration appear. A data selector 95 selects and output inverting bit cadidates 96, 97 of processing primary dimensional or secondary dimensional deterioration with signal 1D/inversion 2D, original video element data 99 and an inverting bit candidate 98 are compared at a read only memory 93, and the inverting bit candidate 98 being permissible range of deterioration of video quality is outputted through inversion. Thus, remarkable compression effect is expected as to video data by combining the deterioration method and the compression coding system. |
