20100141734 | Imaging apparatus and optical axis correction method of imaging apparatus - An imaging apparatus includes a plurality of imaging units each having a lens and an image pickup device. At least one of the imaging units is a wide-angle imaging unit having a lens with a wider angle of view, and at least another one is a zoom imaging unit having a lens with a narrower angle of view and a higher magnification and mounted rotatably to the imaging apparatus. The imaging apparatus includes a driving unit that rotates the zoom imaging unit to change an imaging range of the zoom imaging unit, an image comparison unit that compares a partial image of a wide-angle image captured by the wide-angle imaging unit and a magnified image captured by the zoom imaging unit, and an optical axis information update unit that updates optical axis information of the zoom imaging unit based on a comparison result of the image comparison unit. | 06-10-2010 |
20110242403 | DRIVE DEVICE, IMAGE ACQUISITION DEVICE, AND ELECTRONIC APPARATUS - A drive device in which the frequency of a drive waveform applied to a piezoelectric element is easily settable with less obligation to consider resonance in a stationary member. The device includes a piezo element that expands and contracts according to a drive voltage, a transmission shaft that receives vibration produced by the element, a stationary member that holds the transmission shaft in a slidable state along the longitudinal direction of the transmission shaft, and a lens holder that is displaced together with the piezo element and transmission shaft relative to the stationary member according to drive of the piezo element. The piezo element and the transmission shaft move in the moving direction of the lens holder in synchronization with the lens holder according to drive of the piezo element in the state where the piezo element is spaced from the stationary member. By employing this structure, the frequency of the drive waveform applied to the piezo element can be set easily without considering resonance in the stationary member. | 10-06-2011 |
