Abstract: This application provides an image blur degree determining method and a related device thereof, and relates to the field of image processing. The image blur degree determining method includes: obtaining an original image; determining a homography transformation matrix corresponding to each image block arranged in a column direction in the original image, where the column direction is perpendicular to a row direction in which an electronic device performs row-by-row exposure; and determining a blur degree of the original image based on each image block and the corresponding homography transformation matrix. This application can implement an objective of quickly calculating a blur degree of an image without being affected by image content.
