  • Method and device for interpolating image
    Patent number: 10997691
    Abstract: The present application discloses a method of interpolating an image including a pixel array formed of multiple pixels. The method includes: determining a position of an interpolation point relative to the pixel array; determining weights of an edge direction of the pixel array at the position of the interpolation point in a plurality of preset edge directions based on pixel values of a plurality of pixels adjacent to the interpolation point; selecting, for each preset edge direction, one or more corresponding pixel sub-arrays covering the interpolation point from the pixel array to calculate an interpolation pixel value of the interpolation point; calculating a weighted interpolation pixel value of the interpolation point based on the weights of the edge direction of the pixel array at the position of the interpolation point in the preset edge directions and the interpolation pixel value of the interpolation point corresponding to each preset edge direction.
