There is provided a multi-finger hand device which can perform smooth bending and stretching operations of finger mechanisms in holding work of an object or the like while reducing the number of actuators as driving sources of the bending and stretching operations of the finger mechanisms. The passenger lift is actuated by hydraulic cylinders responsive to hydraulic pressure and fluid flow from a hydraulic pump driven by a DC electric motor, in cooperation with direction and flow control components. In one application to dynamic range adjustment, a saliency map is applied to create a weighed histogram and a transformation is determined from the weighted histogram. Shaft can couple, via clutch, shaft, which couples ring gear of gearset and can couple, via clutch, shaft which couples ring gear and carrier of respective gearsets. Each of the pads has a metal layer such that the metal layer is formed on each of the upper surfaces of the pads and each of the portions of the side walls of the pads exposed by the solder-resist layer. One or more hierarchical verification levels are used to verify whether a human face is in the candidate area, and an indication made that the candidate area includes a face if the one or more hierarchical verification levels verify that a human face is in the candidate area.
