Claim:
1. A method for generating a sharp image based on a blurry image, comprising: acquiring pixel values of pixels in the blurry image and a convolution kernel of the blurry image; determining a deconvolution kernel of the blurry image based on a preset image gradient operator and the convolution kernel; determining pixel values of pixels in the sharp image based on the deconvolution kernel and the pixel values of the pixels in the blurry image; and generating the sharp image based on the pixel values of the pixels in the sharp image, wherein determining the deconvolution kernel of the blurry image based on the preset image gradient operator and the convolution kernel comprises determining the deconvolution kernel according to a formula: wherein ω wherein determining the pixel values of the pixels in the sharp image based on the deconvolution kernel and the pixel values of the pixels in the blurry image comprises:
