<p>PURPOSE:To accurately detect image blur amount by making the value of the oscillating frequency of an angular velocity detecting means detecting angular change on the optical axis of a photographing device as the angular velocity a value which is not affected by a frequency signal generated by another circuit member. CONSTITUTION:An X angular velocity sensor 18 and a Y angular velocity sensor 19 detect the image blur condition of this device as the angular velocity; the oscillating frequencies of the sensor 18 and sensor 19 are set at the value which is not affected by the frequency signal generated by another circuit member. That is, for example, the oscillating frequency of the oscillating circuit of a strobe light emitting tube controlling circuit 5 has the value which is not affected by the frequencies of the sensors 18 and 19. The values of the PWM driving frequencies of an X motor driver 13 and a Y motor driver 17, the value of the executing frequency of a microcomputer 8 for controlling vibration proof, and the clock oscillating frequency of the microcomputer 8, etc., are made the value which is not affected by the frequencies of the sensors 18 and 19.</p> |
