Variable refresh rate dynamic compensation method and device, electronic equipment and storage medium

The invention discloses a variable refresh rate dynamic compensation method and device, electronic equipment and a storage medium. The method comprises the following steps: receiving an Nth frame of picture of a video to be compensated; whether the total scanning line number of the (N-1) th frame of picture is smaller than a preset line number or not is judged, and the preset line number is the scanning line number of each frame corresponding to the highest refresh rate; if the total scanning line number of the (N-1) th frame of picture is smaller than or equal to the preset line number, carrying out picture quality compensation on the Nth frame of picture based on a first compensation coefficient corresponding to the preset line number; and if the total scanning line number of the (N-1) th frame of picture is greater than the preset line number and the total scanning line number of the (N-1) th frame of picture is between the first gear line number and the second gear line number, carrying out picture qualit
