Blurred screen image detection method and device, electronic equipment and storage medium

The invention relates to a blurred screen image detection method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining an edge image of a to-be-detected image, and dividing the edge image into a plurality of sub-regions; edge proportions of edge pixel points in all pixel points in each sub-region are obtained, a proportion set is obtained, and the proportion set comprises edge proportions corresponding to the multiple sub-regions; determining an average value and a fluctuation characteristic value of the plurality of edge proportions in the proportion set, wherein the fluctuation characteristic value is used for representing a fluctuation condition of the plurality of edge proportions relative to the average value; and determining whether the to-be-detected image is a blurred screen image or not according to the average value and the fluctuation characteristic value. According to the embodiment of the invention, the detection of the blurred screen image is more a
