Implementation method for progressively blurred animation

Abstract

The invention provides an implementation method for a progressively blurred animation. The method comprises the steps that an animation is divided into T phases first, wherein keyframes of T+1 phases are included; the maximum blurring radius of keyframe images of the animation is preset as R; the ith keyframe blurred image and the (i+1)th keyframe blurred image are obtained through blurring treatment according to the formula: blurring radius r=i*R / T; the progress p=(r-i*R / T) / (R / T) of a transition frame image located between the ith demarcation point and the (i+1)th demarcation point is obtained, the keyframe blurred image at the (i+1)th demarcation point is mixed to the keyframe blurred image at the ith demarcation point with the progress p as opaqueness, and then a transition frame blurred image is obtained; the keyframe blurred images at all the demarcation points and the transition frame blurred images between the demarcation points are sequentially displayed to obtain the progressively blurred animation. By means of the method, the frame image blurring treatment process in the animation process is simplified, and the animation display effect is smooth.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for realizing progressive blur animation. Background technique [0002] At present, in the field of image processing technology, blurring is often used instead of masks to express hierarchical relationships. However, due to the relatively complicated calculation of blurring, the amount of calculation is much higher than that of masks. If it is applied to animation effects, because animation performance requires Real-time, that is, to satisfy more than 30 screen refreshes per second so as not to cause visual stuttering and incoherence, which requires the device to have stronger processing capabilities. Traditional blurring algorithms have a certain degree of computational complexity, and the computational complexity is proportional to the screen resolution, especially on high-resolution large-screen mobile phones, it is very challenging to achieve progressive blu...
