Blurring animation realization method through Gaussian blurring and blurring animation realization device thereof

Abstract

The embodiment of the invention provides a blurring animation realization method through Gaussian blurring and a blurring animation realization device thereof, and belongs to the technical field of image processing. The method comprises the steps that a corresponding intermediate resolution and the corresponding blurring radius of the intermediate resolution are determined according to the resolution of an original image and the blurring radius set for each time of Gaussian blurring processing of the original image; the maximum image cache space is allocated in advance according to the maximum intermediate resolution; the original image is reduced in each time of Gaussian blurring processing so that an intermediate image is obtained, and the intermediate image is stored in the maximum image cache space, wherein the resolution of the intermediate image is corresponding to the intermediate resolution; Gaussian blurring processing is performed on the intermediate image according to the corresponding blurring radius of the intermediate resolution so that a result image is obtained; and the result image obtained through each time of Gaussian blurring processing is amplified to the size of the original image so that a blurring image is obtained, and the blurring image is displayed after each time of Gaussian blurring processing and thus the blurring animation is obtained.
