摘要： A auto-focusing method comprises setting a plurality of active windows composed of a central window and a plurality of peripheral windows surrounding the central window and allocating weights to the plurality of active windows so as to calculate an auto-focus value for each step; calculating a rate of change in auto-focus value between a previous step and a current step from the auto-focus value calculated for each step; comparing the calculated rate of change in auto-focus value with preset auto-focus reference values and then changing a step size in accordance with the comparison result; transferring a lens to a position corresponding to the changed step size; repeating the above processes from the setting of the plurality of active windows to the transferring of the lens until the auto-focus value of the previous step becomes larger than that of the current step and then determining whether the maximum auto-focus value is detected or not; and transferring the lens to a position corresponding to the maximum auto-focus value.

摘要： A lens driving device includes a lens barrel having a lens holder and an extension part extended from the lens holder. The device also includes a piezoelectric vibrator with a piezoelectric body flexed and bent in response to power application with a friction member in contact with the extension part, thereby providing driving power for transporting the lens barrel. The device further includes a preload member having a free end in resilient contact with a rear end of the piezoelectric body to compress the piezoelectric vibrator against the extension part and a guiding part for guiding the transport of the lens barrel in the optical axis direction. This allows a simplified and miniaturized structure, a large transport range with low input power to achieve excellent resolution of positioning, minimal loss of driving power, simplified mechanism for guiding the transport of the lens, and accurate and stable transport of the lens.

摘要： A piezoelectric transformer using a piezoelectric annulus, divided into sections, includes at least one input and one output electrode configuration. The input electrodes are formed by covering top and bottom surfaces of the divided section of piezoelectric annulus. The low impedance portions, which are input regions, are poled parallel to the thickness direction and the high impedance portions, which are output regions, are poled tangentially. The transformer is operable at several radial mode resonance frequencies of piezoelectric ring. Two stepped up ac output voltages, in phase or 180 degree out of phase, can be obtained at several resonance frequencies of the piezoelectric annulus. The transformer is also operable as a step-down transformer by inverting the input and output ports.
