Abstract
An internal CPU, a vibration control equalizer for processing an output signal of a vibration detector for detecting vibration of an imaging apparatus and calculating a vibration signal for determining a driving amount for an optical component on the basis of vibration of the imaging apparatus, a position control equalizer for calculating a position signal for determining a driving amount for the optical component on the basis of position of the optical component, and a control switching section for switching between the internal CPU and an external control circuit for the imaging apparatus for control of the vibration control equalizer and the position control equalizer.
Claims4
A image stabilization control circuit for reducing influence on image pickup from vibration by driving an optical component of an imaging apparatus according to the vibration, comprising:
- a vibration control equalizer for processing an output signal of a vibration detector for detecting vibration of the imaging apparatus and generating a vibration signal indicating a movement amount of the imaging apparatus on the basis of vibration of the imaging apparatus;
- a position control equalizer for calculating a position signal for determining a driving amount for the optical component on the basis of the vibration signal;
- an internal CPU for controlling operations of the vibration control equalizer and the position control equalizer;
- and
- a control switching section for switching between the internal CPU and an external control circuit for the imaging apparatus for controlling the vibration control equalizer and the position control equalizer.
