PROBLEM TO BE SOLVED: To prevent the malfunction of an equipment by providing a driving current control means making the 1st driving current value of a correction driving means when an image blurring correction means is in a non-locking state different from the 2nd driving current value of the correction driving means in a transition state where the image blurring correction means is shifted from a locking state to the non-locking state. SOLUTION: When instruction for starting image blurring correction operation is communicated to an MPU 31, the MPU 31 converts battery voltage VBAT into digital data. The MPU 31 inputs a 1st value corresponding to the digital data to a D/A converter 50. Analog voltage corresponding to the 1st value is generated at the output of the converter 50. The MPU 31 controls a coil driver 35 so as to energize a shift coil. The MPU 31 controls a motor driver 34 to start to energize a step motor and simultaneously controls a timer to start operation. When the timer finishes counting for a specified time, the MPU 31 controls the motor driver 34 to stop energizing operation. Next, the MPU 31 sets a 2nd value larger than the 1st value at a parallel output port. |
