International ClassG02B 007/04Foreign Application Priority Data1998-06-08 JPAbstractAn optical device comprises correction lenses for correcting a tremble of a focused image. The correction lenses are held by a lateral-direction driving frame which is held by a lengthwise-direction driving frame. The frames are respectively moved by a lengthwise-direction actuator and a lateral-direction actuator. When a power switch of the optical device is turned OFF, motors of the actuators are driven such that the driving frames are respectively moved to reset positions. Further, differences between the reset positions and moving center positions are read from an EEPROM, and the motors of the actuators are driven based on the differences, such that the frames are respectively moved to the moving center positions. Then, the motors are stopped, and a power supply to the optical device is stopped.Field of SearchAutomatic focus controlActive autofocus Plural photosensitive image detecting element arrays IMAGE STABILIZATION By movable reflective structure Having plural reflecting surfaces By movable refractive structure Adjusting mechanism With macro-type focusing CAMERA SHAKE SENSING With accelerometer With photoarray Having stabilization system Optical detail with photoelement system | |
