Motion image blur is very common in the blurred images, and rotating motion image blur is one kind of special and general fuzzy form. Based on the principles of linear motion image blur restoration, to change the rotary motion image into linear motion image blur , this paper propose a regularization recovery mode which is equipped with a norm l1-l2, and with the help of alternative separable function algorithm to solve the model. As a result of the regularization method of norm l1-l2to the noise and ringing has a good inhibitory effect is that the recovery effect is very good.
