팩시밀리의 화상 이진화 처리 시스템 및 그 방식Facsimile Image Binarization Processing System and Its Method

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명 팩시밀리의 화상 이진화 처리 시스템 구성도,1 is a block diagram of an image binarization processing system according to the present invention,

제2도는 제1도의 화상입력에 따른 아날로그/디지탈변환부의 신호처리 흐름도,2 is a signal processing flowchart of an analog / digital conversion unit according to the image input of FIG. 1;

제3도는 제1도의 디더링처리 및 에지검출에 대한 신호흐름도.3 is a signal flow diagram for dithering and edge detection of FIG.

Claims (2)

입력되는 문서의 화상신호를 광전변환에 의해 한라인 단위의 아날로그신호로 변환하는 화상입력부(2)와, 상기 화상입력부(2)의 아날로그신호를 디지탈로 변환하는 아날로그/디지탈변환부(3)와, 상기 아날로그/디지탈변환부(3)의 출력신호를 디더링처리하고 그 더더링처리된 데이타를 에지검출함과 아울러 프로그램롬(6)의 프로그램 수행에 따라 시스템을 제어하는 마이크로프로세서(1)와, 상기 마이크로프로세서(1)로 부터 출력된 흑, 백의 화상데이타를 저장하는 메모리부(5)로 구성함을 특징으로 한 팩시밀시의 화상 이진화 처리 시스템.An image input unit 2 for converting an image signal of an input document into an analog signal in units of one line by photoelectric conversion, and an analog / digital conversion unit 3 for converting an analog signal of the image input unit 2 into digital; A microprocessor (1) for dithering the output signal of the analog / digital conversion unit (3), edge detecting the dithered data, and controlling the system in accordance with program execution of the program ROM (6); And a memory unit (5) for storing black and white image data output from the microprocessor (1). 메모리부에 저장된 문서의 라인데이타를 일정마스크로 나눈 후 각 화소의 그레이값과 이에 상응하는 마이크로 패턴의 그레이값을 비교하면서 이진화로 처리하고, 상기 이진화 처리된 화소값이 흰색일 경우에는 그 화소의 그레이 레벨값과 마이크로 패턴의 상, 하, 좌, 우의 그레이값을 비교하여 상, 하, 좌, 우의 값중 하나라도 일정한 값보다 차이가 크면 그 화소의 색을 흑색으로 바꾸어 화상처리함을 특징으로 한 팩시밀리의 화상 이진화 처리방식.After dividing the line data of the document stored in the memory by a certain mask, the gray value of each pixel and the corresponding gray pattern gray value are compared and processed by binarization. When the binarized pixel value is white, the pixel value of the pixel is processed. The gray level value is compared with the gray value of the upper, lower, left and right of the micro pattern, and if any one of the upper, lower, left and right values is larger than a certain value, the color of the pixel is changed to black and image processing is performed. Facsimile image binarization. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
