Abstract

팩시밀리의 원고화질 변경방법에 관한 것으로, 특히 원고수신중에 수신측에서 원고의 농도나 해상도 변경을 요구하여 송신측에서 자동으로 원고상태를 변경시켜 송신하는 수신측 원고화질 변경방법에 관한 것이다. 팩시밀리에서 화상데이타 수신시 수신원고의 화질이 떨어져 식별하기 곤란할 정도로 화상데이타가 수신되지 않도록 하기 위해 원고수신중에 수신원고의 화질을 변경하기 위한 키신호를 입력하고, 상기 입력한 화질변경키에 해당하는 데이타값을 비표준(NSF)코드에 실어 송신측으로 전송하나, 상기 전송한 비표준(NSF) 코드를 분석하여 변경화질 데이타값으로 화질모드를 변경한 후 이 변경한 원고 화질모드로 원고의 화상데이타를 송신하여 이 송신한 원고의 화상데이타를 수신하도록 한다.The present invention relates to a method for changing the original image quality of a facsimile, and more particularly, to a method for changing the original image quality at the receiving side by requesting the receiving side to change the density or resolution of the original during receiving the original. In order to prevent image data from being received to the extent that it is difficult to identify when receiving image data from the fax, it is necessary to input a key signal for changing the image quality of the received document during document reception, and corresponding to the input image quality change key. The data value is loaded on the non-standard (NSF) code and transmitted to the sender, but the image quality of the original is transmitted in the original image quality mode after changing the image quality mode to the changed image quality by analyzing the transmitted non-standard (NSF) code. To receive the image data of the transmitted original.
