Abstract

A smoothing processing method and device provided by the present invention, comprising: obtaining the current sampling point; based on the current sampling point, reference point and prediction point, respectively obtaining the first movement trend from the reference point to the prediction point, and the first movement trend from the reference point to the current The second movement trend of the sampling point; wherein, the reference point is a point reflecting the historical sampling situation obtained based on the historical sampling point; the predicted point is the point obtained by prediction based on the motion trajectory from the historical sampling point to the reference point; using the first motion The trend and the second motion trend determine the output points. Compared with the prior art, the present invention processes the movement trends from the reference point to the current sampling point and the prediction point respectively, determines the output point, and comprehensively considers the current sampling point and the historical sampling point. Therefore, the present invention has strong automatic adjustment ability, and can quickly track the actual touch point, so as to achieve the effect of ideal smooth curve at any line drawing speed.

Description

technical field [0001] The present invention relates to the technical field of touch screens, and more specifically, to a method and device for smoothing output curves of touch screens. Background technique [0002] With the wide application of the touch screen, some problems also appear, one of which is the smoothing of the output curve of the touch screen. [0003] The conventional touch screen generally adopts a technical method for smoothing the output curve: using the reference point and the current sampling point to determine the output point. In general, the position information of the current sampling point is mainly used to determine the output point, and the function of the reference point is weakened, so it cannot be adjusted automatically in time. Only at a specific line drawing speed can the ideal smooth curve be achieved. Slow, the jagged output lines will be serious, such as figure 1 As shown; if the user draws the line faster, the lag of the output line wil...
