摘要： A blur compensation circuit of an optical image stabilization device includes a movement detection circuit configured to provide a movement detection signal corresponding to a movement of a photographing module; a position detection circuit configured to provide a position signal of an actuator for driving the photographing module; a delta-sigma conversion circuit configured to generate control data corresponding to a deviation between the movement detection signal and the position signal, perform a delta-sigma conversion on the control data, and output driving data corresponding to a result of the delta-sigma conversion; and a driving circuit configured to control driving of the actuator by the driving data.
