Abstract
An exemplary anti-vibration apparatus used in an image pickup system includes a first light-reflecting unit, a driving mechanism configured for driving the light-reflecting unit to rotate, a servo circuit, at least one sensor configured for detecting an angular velocity of the anti-vibration apparatus and sending such signal to the servo circuit, the servo circuit is configured for generating a controlling signal received from the sensor and controlling the driving mechanism based on the controlling signal. The anti-vibration apparatus can eliminate the image vibration caused by the vibration of image pickup system.
Claims15
An anti-vibration apparatus for an image pickup system the anti-vibration apparatus comprising:
- a light-reflecting unit, at least one sensor configured for detecting a rotating angle of θ of the image pickup system in a first rotating direction due to vibration thereof, thus obtaining a feedback signal associated therewith;
- a servo circuit;
- and
- a driving mechanism, the servo circuit being configured for receiving the feedback signal from the at least one sensor and controlling the driving mechanism to rotate the light-reflecting unit through a rotating angle of θ/2 in a second rotating direction opposite to the first rotating direction.
An image pickup system comprising:
- an image pickup device configured for obtaining an image of an object;
- and
- an anti-vibration apparatus comprising:
- a first light-reflecting unit
- at least one sensor configured for detecting a rotating angle of θ of the image pickup system in a first rotating direction due to vibration thereof, thereby obtaining a feedback signal associated therewith;
- a servo circuit;
- and
- a driving mechanism, the servo circuit being configured for receiving the feedback signal from the at least one sensor and controlling the driving mechanism to rotate the light-reflecting unit by a rotating angle of θ/2 in a second rotating direction opposite to the first rotating direction.
