Title:
PHOTOGRAPHIC DEVICE
Document Type and Number:
Japanese Patent JPH0194769
Kind Code:
A
Abstract:
PURPOSE:To obtain a miniature and light-weight photographic device with small energy consumption by controlling a current flowing in the stator winding of an actuator to make the detection output of each angular velocity sensor zero to the blurring of a lens mirror body and a face blurring in an oblique direction. CONSTITUTION:A control circuit 87 supplies power to a stator windings 65 and 83 of actuator 88 and 89 respectively, and controls them so that the detecting outputs of angular velocity sensors 85 and 86 of lens mirror body 58 accompanying a video camera go to zero, thus, the swinging of the mirror barrel 58 to absolute coordinates disappears and horizontal and vertical blurring is decreased. When the face blurring in the oblique direction occurs, swinging quantity (angular velocity) is presented by the angular velocity sensor 85 (panning direction) and the angular velocity sensor 86 (tilting direction), the control circuit 87 supplies the power to the stator windings 65 and 83 of the actuators 88 and 89 respectively, so that the outputs of the two directional sensors 85 and 86 go to zero and thus, the face blurring in the oblique direction can be prevented.
