The invention relates to the technical field of image processing and display, and provides an image processing method based on a vertical synchronization signal, electronic equipment and a storage medium, and the method comprises the steps that the electronic equipment responds to a first vertical synchronization signal, draws and renders, and buffers a first image layer in a first buffer queue at a first moment; and under the condition that the first moment is after the second vertical synchronization signal and the third vertical synchronization signal does not have the first image frame to be refreshed and displayed, the electronic equipment immediately triggers the first image layer at the first moment to carry out image layer synthesis to obtain a second image frame. Wherein the second vertical synchronization signal is after the first vertical synchronization signal and is spaced by a first preset period, and the third vertical synchronization signal is after the second vertical synchronization signal and is spaced by a second preset period. Therefore, when the drawing of the first image layer is delayed and the second image frame can be refreshed and displayed by the corresponding third vertical synchronizing signal, the immediate synthesis is triggered, so that frame loss can be avoided, and the smoothness of image display is ensured.
