Image blurring methods and apparatuses, storage media, and electronic devices. The method can be carried out by the apparatuses, media and devices, and includes: generating a second image having second pixel points corresponding to first pixel points of a first image; determining, according to blurring desired data of the first pixel points, respective initial blurring weight values of the corresponding second pixel points; performing at least one update on at least one of the second pixel points, the update including: updating, based on a first pixel value of the first pixel point and a current blurring weight value of the second pixel point corresponding to the based first pixel point, a current pixel value and a current blurring weight value of at least one neighboring second pixel point of the based corresponding second pixel point; and obtaining a blurring result of the first image according to the updated second image.
