Abstract: An image rendering method and apparatus, a device, and a medium. The method includes: determining a pre-captured initial rendering video stream for a background image; obtaining initial rendering coordinates of each rendering pixel in each initial rendering image frame in the video stream, and obtaining a rendering moment of each initial rendering image frame in the initial rendering video stream; determining the amount of noise of each rendering pixel at the corresponding rendering moment according to the corresponding initial rendering coordinates, a preset noise texture, and the corresponding rendering moment, and obtaining target rendering coordinates of each rendering pixel according to the corresponding amount of noise; and updating the initial rendering coordinates of each rendering pixel according to the corresponding target rendering coordinates to obtain a target rendering image, and rendering the background image according to a target rendering video stream composed of all target rendering images.

Abstract: A method and apparatus for implementing a water ripple effect, an electronic device, and a computer readable storage medium are provided. The method obtaining a current image frame in an original video; selecting a water ripple map corresponding to the current image frame from a pre-obtained water ripple map sequence; determining displacements of respective pixels in the water ripple map, and forming a displacement vector diagram by using the displacements of the pixels; determining coordinates of respective pixels in the current image frame based on the displacement vector diagram to obtain a first water ripple distortion image; and determining a water ripple effect image corresponding to the current image frame based on the first water ripple distortion image and the water ripple map.
