OPTICAL IMAGE STABILIZER AND CAMERA MODULE INCLUDING THE SAME |
摘要 |
An optical image stabilizer including an angular velocity calculator configured to receive an angular velocity signal from an angular velocity sensor and output a corrected angular velocity signal generated by correcting the angular velocity signal and an angular position signal generated by integrating the corrected angular velocity signal; a state detector configured to calculate an amount of energy by summing squared values of the corrected angular velocity signal during an energy period, comparing the amount of energy with a threshold value to determine a stopped state or a moving state of a camera module, and output a corrected angular position signal and control coefficients; and a lens controller configured to control a lens module according to the corrected angular position signal and the control coefficients. |
