Abstract: An image processing method includes determining, based on a coordinate position of a to-be-interpolated sample in a target image, a first coordinate position of the to-be-interpolated sample in a source image, determining m reference samples based on the first coordinate position, determining an interpolation weight of each of the m reference samples for the to-be-interpolated sample based on a spherical distance between a coordinate position of each of the m reference samples and the first coordinate position, and determining a pixel value of the to-be-interpolated sample based on a pixel value corresponding to each of the m reference samples and the interpolation weight of each of the m reference samples for the to-be-interpolated sample to obtain the target image.
