According to an embodiment of the present invention, provided are an image stabilizer which is less sensitive to noises, temperature, etc. and can determine a stop state having high reliability, and a camera module including the same. The present invention relates to the image stabilizer and the camera module including the same. The camera module according to an embodiment of the present invention can comprise: an angular speed sensor to output an angular speed signal by detecting an angular speed; an angular speed calculation unit to output a corrected angular speed signal which corrects the angular speed, and an angular position signal which integrally calculates the corrected angular speed signal; a stop state sensing unit to calculate an auto-correlation value based on the corrected angular speed signal, to determine a stop state by comparing the auto-correlation value with a threshold value, and to output a corrected angular position signal and control coefficients; a lens control unit to output a control signal based on the corrected angular position signal and the control coefficients; and a lens module to control the position of a lens barrel according to the control signal. |
