The invention discloses an image processing method and device, and a storage medium. The image processing method comprises the steps of obtaining an original blurred image; coordinate system conversion is carried out, the original blurred image is converted into a polar coordinate system, and a polar coordinate blurred image is obtained; according to the rotation angular velocity and the exposure period, a motion blur model is obtained in a polar coordinate system, the motion blur model comprises a blur kernel, and the blur kernel has spatial invariance; and based on the motion blur model, carrying out blur elimination processing on the polar coordinate blurred image to obtain a clear image. In the technical method provided by the invention, the blurring kernel in the motion blurring model has spatial invariance, so that the process of eliminating the blurring can be realized by using the existing technology, even if the process of eliminating the blurring by using the existing technology becomes possible, th
