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.

The present invention discloses a lens control device and a control method thereof, a lens driver and a control method thereof, and a follow focus control system. The lens control device includes adjusting members. The control method of the lens control device includes: upon detecting a change of position data of any one adjusting member, acquiring current position data of the adjusting member and a matching identification corresponding to the adjusting member; and generating and wirelessly transmitting an adjustment signal based on the acquired position data and the matching identification, the adjustment signal containing the matching identification, the matching identification being provided for a lens driver that receives the adjustment signal to perform a match verification. The technical solution of the present invention effectively prevents the communication signals between the lens control device and the lens driver from being interfered with and improving control accuracy of the lens.

A gear for adjusting a camera lens barrel includes a gear body having a continuous inner surface defining an inner diameter and a continuous outer surface defining an outer diameter. The gear is elastically deformable such that the gear is securable about the camera lens barrel whereby the gear is removable and is reusable. The inner diameter of the gear is elastically deformable by at least 0.6 millimeters.

There is provided an information processing device including a control part configured to control an imaging operation on the basis of a contact state of an object in a lens barrel that houses an optical system.

An apparatus that is wearable by a solo video camera man that allows for solo focusing of subjects without the need for a focus follow The device allows for one operator to work the camera and focus it without touching the lens through one hand operation of the lens. There is silent operation for sound recording while filming. The device is modifiable for left hand or right hand use. The device is foldable for portability. The device provides a stable platform for portable camera operation. There is adjustable focus tension for micro control and operator preference. There is an add-on surround frame to support sound and lighting equipment that moves with the camera and that can also house a monitor. The system includes a vest and adjustable support strut that makes hands-free use fatigue-free between scenes. A scale linked to the lens focus makes pre-set focus points easy to mark and visually reference by the single operator. The unit can be tripod mounted for stationary filming. The fold down back stop is adjustable in and back along the shoulder support bars to provide repeatable eye relief to camera or affixed monitor. The back stop and shoulder supports provide a gripping, tacky surface for stability. There is a direct mechanical link between the control handle and the lens focus and no cables or gears with backlash or slippage.
