팩시밀리에서의 2치 화상 부호화 장치Binary picture coding apparatus in facsimile

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명에 의한 2치 화상 부호화 장치의 블록 구성도.1 is a block diagram of a binary image coding apparatus according to the present invention.

Claims (1)

2차원적으로 주사된 각 라인의 화상신호를 저장하는 참조 및 부호화 라인메모리(1), (2)와, 상기 참조 및 부호화 라인메모리(1), (2)로 부터 판독된 화상데이타를 일시적으로 기억시키는 메로리 래치 회로(4), (5)와, 외부에서 정지 신호가 입력될때까지 하나씩 자동적으로 계수를 반복하여 상기 참조 및 부호화 라인메모리(1), (2)에 저장된 화상신호를 순차적으로 독출시키는 어드레스 카운터(3)로 구성된 2치 화상 부호화 장치에 있어서, 상기 어드레스 카운터(3)의 동기와 일치하고 참조 및 부호화 라인 메모리(1), (2)에서 독출되어진 서로 인접한 복수화소의 신호를 동시에 출력시키는 시프트 레지스터(6), (7)와, 상기 어드레카운터(3)의 값을 참조하고 시프트 레지스터(6), (7)에 저장된 이전에 결정된 화소를 검출하여 래치용 제어신호를 송출하는 래치제어회로(8)와, 상기 래치제어회로(8)의 제어 신호에 의해 시프트레지스터(6), (7)에 각각 저장되어 있는 복수 화소의 화상 신호를 일시적으로 기억시키는 시프트 레지스터 래치회로(9), (10)와, 상기 시프트 레지스터 래치회로(9), (10)에서 출력된 복수화소의 화상 신호 데이타를 소정의 패턴에 합치하는가를 검출하는 부호검출회로(11)와, 상기 부호검출회로(11)의 출력을 일시적으로 선입선출메모리(12) 상기 선입선출메모리(12)에 저장된 부호검출회로(11)의 검출부호와 대응하는 부호어로 변환하여 전송로용 부호어로 출력시키는 부호 변환회로(13)를 구비하여서 된 것을 특징으로 하는 팩시밀리에서의 2치 화상 부호화 장치.Reference and encoding line memories (1) and (2) for storing image signals of each two-dimensionally scanned line, and image data read from the reference and encoding line memories (1) and (2) temporarily. The memory latch circuits 4 and 5 to be stored are automatically repeated one by one until a stop signal is input from the outside, and the image signals stored in the reference and encoding line memories 1 and 2 are sequentially read out. A binary image encoding device comprising: an address counter (3) configured to cope with the synchronization of said address counter (3) and simultaneously to receive signals of a plurality of adjacent pixels which are read out from reference and encoding line memories (1) and (2) simultaneously. A latch for referring to the shift registers 6 and 7 to be output and the values of the address counter 3 and detecting previously determined pixels stored in the shift registers 6 and 7 to send a latch control signal. Control circuit (8) And shift register latch circuits 9 and 10 for temporarily storing image signals of a plurality of pixels stored in the shift registers 6 and 7, respectively, by the control signal of the latch control circuit 8. A code detection circuit 11 for detecting whether or not the image signal data of the plurality of pixels output from the shift register latch circuits 9 and 10 conforms to a predetermined pattern, and the output of the code detection circuit 11; A code conversion circuit 13 for temporarily converting a code word corresponding to a detection code of the code detection circuit 11 stored in the first-in first-out memory 12 into the first-in first-out memory 12 and outputting the code word for a transmission path. A binary image encoding device in a facsimile. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
