PURPOSE: To improve the processing speed by separating the entire device into two devices for detecting a coding mode and for restoring a picture signal and absorbing the difference of the processing speed between both devices by means of an FIFO memory so as to execute two independent processings in parallel.
CONSTITUTION: A binary picture decoder consists of a coding mode detector 100 and a picture signal restoring device 200, a code word series inputted to a coding memory 5 of the device 100 is stored temporarily, a coding mode detecting circuit 6 detects the code by the control of the 1st control circuit 4a so as to decide the code word mode. The decided code word mode is stored tentatively in the FIFO memory 8 and read to a changing point detecting circuit 11 under the control of the 2nd control circuit 4b of the device 200. Further, a restored picture value comprising a signal of plural picture elements is stored in an FF7 sequentially by means of a line memory 1 and a shift register 10 or the like in response to the coding mode of the circuit 11, so as to execute the code mode detection and the picture signal restoration independently in parallel thereby quickening the processing speed.
