Document Type and Number:
WIPO Patent Application WO/2013/085355
Kind Code:
A1
Abstract:
An apparatus and method for compensating hand blur are disclosed. The method according to an exemplary embodiment of the present invention comprises receiving an angular velocity by tilt of the camera module, determining a first driving signal for driving the second actuator using the angular velocity, calculating a ratio of effective focal length relative to a lens moving distance using the driving of the first actuator, and determining a second driving signal amplifying the first driving signal, using the ratio of effective focal length relative to the lens moving distance.
