Abstract
An angular speed of an optical axis of an optical device is detected by a gyro sensor, and inputted to a first A/D converting input terminal of a CPU. A position data of a correction optical system is sensed by a PSD, and inputted to a second A/D converting input terminal of the CPU. The inputted data both of the first and the second A/D converting input terminals is converted to a digital signal. The digital signal of the angular speed is stored in an integration register. The digital signal of the position data is stored in a correction optical system position register. When a trembling speed of a focused image changes from a speed higher than a maximum driving speed of the correction optical system to a speed lower than the maximum speed, the data stored in the correction optical system position register is copied to the integration register.
