Real-time Gaussian Blur method and device of video on mobile equipment

The invention provides a real-time Gaussian Blur method and device of a video on mobile equipment. The method comprises the following steps: applying an application program programming interface for preset graphic processing on mobile equipment; calling the application program programming interface to carry out Gaussian Blur processing to each pixel in one frame of image of the video to be processed by a graphics processor of the mobile equipment, wherein the Gaussian Blur processing comprises the following steps: according to the laterally adjacent pixels of the pixel, carrying out one-dimensional lateral Gaussian convolution, and carrying out one-dimensional longitudinal Gaussian convolution according to the longitudinally adjacent pixels of the pixel; and rendering a Gaussian Blur processing result of each pixel, and displaying a rendering result on a mobile equipment interface.
