Claims (1)

송신원고(2) 독취전에 백기준면을 독취하여 기준값 레벨을 메모리(7)에 저장한 후에, 백기준면의 레벨과 송신원고의 농도면을 비교하여 상기 백기준면 레벨이 송신원고의 레벨보다 작으면, 라인별로 송신원고의 시작 어드레스 P1(t)와 종료 어드레스 P2(t)를 기억시킨 후 매 라인별로 구하고, 1-P1(t)번째의 pe1은 백으로 처리하고, ＆[P1(t)∼P2(t)]는 송신원고내의 레벨을 기준으로 화상데이타 처리를 행하며, 이후에 화신호 처리를 수행한 라인은 대역 압축을 하여 송신한 후 화신호의 1라인을 송신하는 과정에서 라인번호(N)를 1만큼 증가시키고 나서 상기 화신호처리를 매 라인마다 다시 수행하여 송신하도록 하는 팩시밀리에서의 화상처 리방법.After reading the white reference plane before reading the transmission original 2 and storing the reference value level in the memory 7, after comparing the level of the white reference plane with the density plane of the transmission original, if the back reference plane level is smaller than the level of the transmission original, After storing the start address P 1 (t) and the end address P 2 (t) of the original for each line, obtain each line, pe1 in the 1-P 1 (t) is processed as white, and & P 1 ( t) to P 2 (t)] perform image data processing on the basis of the level in the transmission document, and then, after performing the signal processing, the line is subjected to band compression, and then one line of the signal is transmitted. The image processing method in a facsimile which increases the line number (N) by one, and then performs the transmission signal processing again every line. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
