摘要
The present invention discloses a method for generating a sharp image based on a blurry image. The method includes: 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. A deconvolution kernel in the embodiments of the present invention is determined based on a gradient operator and a convolution kernel; in other words, the deconvolution kernel introduces the gradient operator as a regularization constraint, which prevents noise from affecting an image recovery process, and improves the quality of a recovered sharp image.
