Image sharpening method, electronic device, storage medium and computer program product

The embodiment of the invention discloses an image sharpening method, electronic equipment, a storage medium and a computer program product. The method comprises the following steps: extracting high-frequency information of a to-be-sharpened first image; edge information of the first image is extracted, a texture mask of the first image is generated according to the edge information, and the texture mask is used for distinguishing a noise area and a non-noise area in the high-frequency information; and enhancing a non-noise area in the high-frequency information according to the texture mask to obtain a second image. According to the method, the texture mask can effectively distinguish the noise and the non-noise, so that the texture mask is adopted to enhance the high-frequency information, the non-noise information in the high-frequency information can be selectively enhanced, the separation of the noise and the edge is realized, the noise is not amplified while sharpening is realized, and the image quality
