1. A multi-image stabilization device comprising:
a driver circuit generating at least one of a lens driving signal for image stabilization of a lens assembly of a camera body portion and a sensor driving signal for image stabilization of an image sensor unit of the camera body portion based on gyro sensor information input from a gyro sensor detecting a hand-shake of the camera body portion,
wherein
the driver circuit generates the lens driving signal having a first driving current for high-angle and low-frequency image stabilization in an event of a high-angle hand-shake but not a high-frequency hand-shake based on the gyro sensor information,
the driver circuit generates the lens driving signal having a second driving current for high-angle and high-frequency image stabilization in an event of a high-angle hand-shake and a high-frequency hand-shake,
the driver circuit generates the lens driving signal having a third driving current for low-angle and low-frequency image stabilization in an event of not a high-angle hand-shake and not a high-frequency hand-shake, and
the driver circuit generates the sensor driving signal for low-angle and high-frequency image stabilization in an event of a high-frequency hand-shake but not a high-angle hand-shake.
