摘要:
An auto calibration method and an optical image stabilizer (OIS) camera using the same are provided. The auto calibration method includes removing a DC offset of a gyroscope. A vibrator signal applied by operating a vibrator, and an actual measurement value of the gyroscope is obtained using the applied vibrator signal. A first gain value for compensating for sensitivity of the gyroscope is calculated using the vibrator signal and the actual measurement value of the gyroscope, and an actuator is operated. A displacement of a pixel actually moving on an image is moved under an operation of the actuator. A second gain value for controlling a sensitivity variation of the actuator is calculated based on the displacement of the actually moving pixel. Accordingly, it is possible to reduce processing time and to ensure high performance.
