Abstract: A focus control apparatus controls a step motor and a piezoelectric material into order to control a focal distance between an electronic imaging device and a lens unit. The focus control apparatus has an image calculating unit for processing an image signal taken by the electronic imaging device into a resolution value, a displacement controlling unit receiving the resolution value in order to determine an optimal focal distance between the electronic imaging device and the lens unit and output a displacement controlling signal, a step motor controller and a piezoelectric material controller. The displacement controlling signal is supplied to the step motor controller or the piezoelectric material controller to control optimally the distance between an electronic imaging device and a lens unit.

Abstract: A piezoelectric focusing apparatus and method for the same are proposed to quickly adjust a distance between a lens unit and an electronic imaging device. An expanding table associated with increased voltage and a shrinkage table associated with decreased voltage for the piezoelectric material is constructed. A bi-directional deformation table is then established by associating voltages on the expanding table and the shrinkage table corresponding to the same deformation. A voltage is supplied to the piezoelectric material according to the bi-directional deformation table for generating a desired deformation and controlling a focusing distance between the lens unit and the electronic imaging device.

Abstract: A substrate, a layer of UV curable ink and a transparent layer of film, which has holographic images embossed on it. Patterns are printed on the substrate using a UV curable ink in its uncured state. When a hologram film is laminated to the substrate containing the UV curable inked pattern and exposed to UV light, the portion of the hologram film in contact with the UV curable ink adheres to the substrate as part of the curing process. The remaining part of the holographic film is peeled off from the substrate.
