  • Image stabilization control circuit for imaging apparatus
    Patent number: 8482621
    Abstract: A vibration control equalizer for generating a vibration signal for determining a driving amount for an optical component on the basis of an output signal of a vibration detector for detecting vibration of an imaging apparatus, a position control equalizer for calculating a position signal for determining a driving amount for the optical component on the basis of an output signal of a position detector for detecting position of the optical component, and an internal CPU for controlling the vibration control equalizer and the position control equalizer are provided, and compensation for the output signal of the position detector is performed by the internal CPU.
