A method for vignetting correction of an image according to an exemplary embodiment of the present disclosure may comprise receiving a two-dimensional image; calculating a radial bright channel representing intensity of the two-dimensional image; estimating a vignetting function of the two-dimensional image having similarity to the calculated radial bright channel; and correcting the vignetting effects of the two-dimensional image by using the estimated vignetting function. The vignetting correction methods and apparatuses according to the present disclosure can rapidly correct vignetting effects of an image by using a smaller memory, and correct vignetting effects of an arbitrary single image without being affected by a camera setting and camera lenses used for the image."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for vignetting correction of image and apparatus therefor","description":"Method and apparatuses for correcting vignetting effects of an image are disclosed.
