http://appft1.uspto.gov/netacgi/n..................FTTH+or+FTTP+or+PON United States Patent Application 20050196160 Kind Code A1 Uenaka, Yukio September 8, 2005 Anti-shake apparatus Abstract An anti-shake apparatus comprises a movable-unit, a fixed-unit, a signal-processing unit, and a control-unit. The movable-unit has an imaging-device and is changeable in first- and second-directions. The control-unit has first and second A/D-converters. The movable-unit has horizontal and vertical hall-elements. The signal-processing unit outputs a first detected-position-signal specifying a first-location from output-signals of the horizontal-hall-element to the first-A/D-converter, and outputs a second detected-position-signal specifying a second-location from output-signals of the vertical-hall-element to the second-A/D-converter. The control-unit calculates the first-location from an A/D-converting-operation by the first-A/D-converter, for the first detected-position-signal, calculates the second-location from an A/D-converting-operation by the second-A/D-converter, for the second detected-position-signal, and maximizes widths between minimum and maximum values of the first detected-position-signal in a horizontal-movement-range of the movable-unit and in an A/D-converting-range, and of the second detected-position-signal in a vertical-movement-range of the movable-unit and in an A/D-converting-range. The horizontal- and vertical-movement-ranges are proportional to a focal-distance.
