팩시밀리에 있어서 화상독취부 및 기록부의 대각선 샘플링방식Diagonal Sampling Method of Image Reader and Recorder in Fax

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

제3도는 본 발명의 대각선 샘플링의 설명도, 제4도는 제3도에 따른 공간주파수 성분의 분포도.3 is an explanatory diagram of diagonal sampling according to the present invention, and FIG. 4 is a distribution diagram of spatial frequency components according to FIG.

Claims (2)

화상독취부 및 화상기록부를 구비한 팩시밀리의 화상샘플링 방식에 있어서, 상기 화상독취부에서는 마름모 형태의 격자 상에서 화상을 샘플링하는 대각선 샘플링을 행하고, 상기 화상기록부에서는 상기 대각선 샘플링 할 때와, 동일한 방향으로 기록점들의 위치를 이동시켜 화상을 재현함을 특징으로 하는 화상독취부 및 기록부의 대각선 샘플링방식.In a facsimile image sampling method having an image reading unit and an image recording unit, the image reading unit performs diagonal sampling for sampling an image on a rhombus-shaped grid, and the image recording unit in the same direction as when the diagonal sampling is performed. A diagonal sampling method of an image reading unit and a recording unit characterized by reproducing an image by moving the positions of the recording points. 제1항에 있어서, 상기 대각선 샘플링이 행하여질때 현재의 스캔라인에 이웃하는 스캔라인의 샘플링 점들의 위치가 현재의 스캔라인의 샘플링 점사이의 간격의 반만큼 일률적으로 이동시킴을 특징으로 하는 화상독취부 및 기록부의 대각선 샘플링방식.2. The image read according to claim 1, wherein when the diagonal sampling is performed, the positions of the sampling points of the scan lines neighboring the current scan lines are shifted by half of the interval between the sampling points of the current scan lines. Diagonal sampling method for mounting and recording. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
