Abstract

The invention discloses a waveform saw tooth resisting method and a waveform saw tooth resistance processing device. The treatment on the displayed waveform line of prior sampling points comprises: using a sampling unit to obtain three data groups of adjacent domains of the displayed waveform lines of the last sampling point, the prior sampling point and the next sampling points; according to the data of adjacent domains, using a calculation unit to determine the characteristic region and the marginal region of the displayed waveform line of the prior sampling point; using a display processing unit to display the characteristic region via foreground color and display the marginal region via graded color. The invention can effectively resolve the saw tooth condition of waveform, and only needs to obtain the data of the prior sampling point, the last sampling point and the next sampling point to processing the image of one sampling period, to process saw tooth resistance. The method has low computational amount and no delay, is especially suitable for processing real-time waveform, and processing the waveform of small size and insufficient data of adjacent domains.

Description

technical field

[0001] The invention relates to a waveform processing method and processing device, in particular to a method and device for performing anti-aliasing on waveforms. Background technique

[0002] Sampling and displaying waveforms are involved in many fields. From a mathematical point of view, the waveform is a continuous smooth curve, and all its points are infinitely small "ideal" points; but the display is not an "ideal" display medium, it is discrete, the smallest The display unit of the display is a pixel; a pixel is not a point, but a tiny rectangular area on the screen; this difference leads to almost all waveforms, whose data points are not always exactly one-to-one corresponding to the pixels on the display, except for this waveform When it is vertical, horizontal or inclined at 45 degrees, but such waveforms are rare. The simplest and fastest method is to discard the data that cannot be corresponded, and connect the points that can be accurately corr...
