A lens device includes a first electric motor, a second electric motor, a lens, a cam ring, a first gear, a second gear, and a controller. The cam ring is configured to drive the lens in a direction of an optical axis of the lens. The first gear is configured to transmit power generated by the first electric motor to the cam ring. The second gear is configured to transmit power generated by the second electric motor to the cam ring. The controller is configured to, when controlling the cam ring to stop rotating, first stop a rotation of the first electric motor and then stop a rotation of the second electric motor.

A control method of a driving mechanism is provided, including: the driving mechanism provides a first electrical signal from a control assembly to the driving mechanism to move the movable portion into an initial position relative to the fixed portion, wherein the control assembly includes a control unit and a position sensing unit; the status signal of an inertia sensing unit is read; the control unit sends the status signal to the control unit to calculate a target position; the control unit provides a second electrical signal to the driving assembly according to the target position for driving the driving assembly; a position signal is sent from the position sensing unit to the control unit; the control unit provides a third electric signal to the driving assembly to drive the driving assembly according the position signal.

Disclosed is a distance vision-realizing eyeglasses for an image display device, including: a case which surrounds an eye area of a wearer and has a pair of holes formed in front thereof; a double convex lens assembly which includes a pair of lens housings respectively mounted in the pair of holes of the case and a pair of double convex lenses respectively provided in the pair of lens housings on a front straight line of both eyes of the wearer, the pair of the double convex lenses including an outer convex lens positioned on an outer side and fixed to the lens housing and an inner convex lens positioned inside the lens housing and mounted movably forward and backward; and a driving part which is installed between the pair of lens housings and moves a pair of inner convex lenses of the double convex lens assembly.

A remote control unit for controlling a motion picture camera comprises a grip section at a first side for holding the remote control unit, an extension section at a second side and a display section extending from the grip section to the second side. The display section comprises a display at a front side thereof, which is oriented orthogonal to a viewing axis. The extension section projects away from the display section. The extension section comprises an operating side facing away from the grip section, at which side a rotatable operating element for setting control commands is arranged.

An actuator for adjusting an element to be moved in a beam path of an optical arrangement contains the element to be moved, a carrier and at least one SM element, the SM element being connected to the element to be moved and designed such that it is supported on the carrier, so that when the dimension of the SM element changes, a directed force effect is produced between the element to be moved and the carrier.

An adjustment device and associated method is disclosed, for adjusting an equipment, such as a camera, having an actuator for adjusting a variable setting, such as a lens setting (focus, iris, zoom). A control system drives the actuator and command component of the adjustment device to reflect a position of the actuator. In a slave mode, the command component is driven by the control system. In an override mode, a manual operation of the command component drives the actuator of the equipment. Also disclosed are a method for building a model of a lens, a method for treating an image capture to produce a visual effect, a method for creating a node in a model representing a given space, a method for setting a node in a model based on a known node, and a method for calibrating a node in a model.
