Apparatus for driving voice coil actuator of camera and method thereof
An apparatus for driving a voice coil actuator of a camera and a method thereof are provided. The driving apparatus performs input shaping based on a resonance frequency of a voice coil actuator and damping of vibration in the voice coil actuator to generate a control signal using a shaping signal as an initial input from an unshaped control signal, and thereby drives the voice coil actuator using the control signal subjected to input shaping. The shaping signal is provided to remove the resonance of the voice coil actuator, and may be a pure shaping signal, such as a multi-step shaping signal or a toggle shaping signal, or a convoluted shaping signal obtained by convoluting such pure shaping signals. The driving apparatus may significantly reduce residual vibration and may enhance an auto-focus function of the voice actuator using input shaping control based on damping.

DEVICE FOR DRIVING VOICE COIL ACTUATOR IN CAMERA AND METHOD THEREFOR
Disclosed are a device for driving a voice coil actuator in a camera and a method therefor. The device for driving a voice coil actuator performs input shaping on the basis of a resonance frequency of the voice coil actuator and attenuation of vibration appearing in the voice coil actuator so as to generate a control signal having a shaping signal, as an initial input, from a primitive control signal, and drives the voice coil actuator by the control signal for which the input shaping has been performed. The shaping signal is for eliminating resonance of the voice coil actuator, and may include multi-step or toggle-type pure shaping signals having a form in which the range of signal fluctuation is gradually attenuated due to attenuation applied thereto or may be a convolution shaping signal having such pure shaping signals convoluted each other. Accordingly, the present invention can further improve residual vibration suppression performance and auto focus performance of the voice coil actuator, by input shaping control in consideration of attenuation.
