PROBLEM TO BE SOLVED: To provide a motion device control circuit, a method for controlling the circuit, a method for adjusting the circuit, and a motion device controller, the motion device control circuit having a maintained stability of a closed loop even with manufacturing variations and having lens responsivity prevented from decreasing.SOLUTION: A target signal generation circuit 16 generates a target position signal H indicating the target position of a motion device 1. A driving signal generating unit 13 outputs a driving signal D to a driving unit 14 driving the motion device 1, based on a position sensor signal S having detected the position of the motion device 1 and the target position signal H. A first adjusting unit 112 adjusts filter characteristics of input and output of the driving signal generating unit 13, based on a signal corresponding to the driving signal D.SELECTED DRAWING: Figure 1 |
