摘要： The invention includes a vibration reduction mechanism, a vibration detecting part, a reference signal generating part, a target drive position calculating part, and a driving part. The vibration reduction mechanism reduces a vibration of a subject image. The vibration detecting part outputs a vibration detection signal. The reference signal generating part estimates a reference signal of the vibration detection part. The target drive position calculating part obtains a vibration component from a difference between the vibration detection signal and the estimated reference signal to obtain a target position to which the vibration reduction mechanism is driven. The driving part controls the vibration reduction mechanism to follow the target position. Particularly, the reference signal generating part corrects the reference signal according to a motion signal obtained from a captured image. An accurate reference signal can be obtained by the correction, thereby improving the performance of the vibration reduction.

摘要： An inverter apparatus for converting a DC power converted from an input AC power to an output AC power of a variable frequency and a variable electric power to drive an induction motor at a variable speed. The inverter apparatus includes a rectifying unit, a filter capacitor, an inverter unit having an input connected across the filter capacitor, an input current detector and a gate circuitry for driving the inverter unit. An excitation current detection unit detects an excitation current of the induction motor from an output signal of the input current detector, a gate signal for driving the gate circuitry and a reference phase command. A setting unit sets a limitation level of the excitation current, a torque boost voltage command unit produces a torque boost voltage command, and a torque boost voltage compensation unit changes the torque boost voltage command so that the detected excitation current value is smaller than or equal to the limitation level.

摘要： Induction voltage command Em* is obtained from inverter's primary frequency command &ohgr;1* and torque boost voltage commander produces torque boost voltage command &Dgr;Vz* in accordance with &ohgr;1* while integrator produces reference phase command &thgr;d*. uvw/dq converter detects motor excitation current Id (equivalent of no-load current). Next, deviation of excitation current limitation level command Idmax* and detected Id is inputted to limiter processing unit to produce torque boost voltage compensation value &Dgr;Vc for varying &Dgr;Vz* so that Id is smaller than or equal to Idmax*. Inverted &Dgr;Vz* is set up as a lower limiter value of the limiter processing unit. Next, &Dgr;Vc and &Dgr;Vz* are added to produce final compensated torque boost voltage command &Dgr;Vt* and &Dgr;Vt* and Em* are added to produce q-axis voltage command Vq* of the inverter output voltage.

摘要： A motion compensation device which detects vibration of an optical system and can discriminate between undesired movement or vibration of photographic equipment and intentional movement of the photographic equipment and compensate for the undesired movement while not compensating for the intentional movement. The motion compensation device contains a decision unit which calculates a variance value based on an angular velocity signal supplied by am angular velocity sensor. The decision unit then compares this variance value with a predetermined decision level value and determines if a large movement has occurred due to a photographic composition change, panning photography or the operator following of a randomly moving subject. A target value calculation unit, based on the decision result of the decision unit, calculates a target value of vibration motion compensation control to be executed. The target value calculation unit then varies the target value of vibration motion compensation control when large movements are detected by the angular velocity sensor. This motion compensation device may be contained within a lens barrel or camera body.
