PURPOSE:To attain high speed processing of a decoder of input bit stream. CONSTITUTION:Specific data such as staffing user data or the like not in direct relation to image forming in an input bit stream 100 are eliminated by a specific data elimination means 30 to reduce the processing quantity and the reduced multi-value processing of data is stored in a buffer memory 12 and after the data reach a prescribed quantity, the data are read out of the buffer memory 12. Then a variable modulation decoder 21 decodes the data to obtain a reproduced image 200. |
