A weight of a movable portion in a shutter unit is reduced. For this purpose, an imaging device according to the present technology includes: an imaging element that receives light from a subject and performs photoelectric conversion; a control unit that controls a timing of a charge reset of the imaging element; and a shutter unit including a base part that is disposed on a front surface of the imaging element and includes an opening through which light passes, an opening and closing blade that shields a part of the opening from light depending on the timing of the charge reset, and a support part that supports the opening and closing blade. As a result, only one opening and closing blade is included, a width of the opening and closing blade in a traveling direction is smaller than a width of the opening in the traveling direction, and the weight of the movable portion in the shutter unit can be reduced.

A method for camera image stabilization includes a method for detecting blur in an image; measuring vibration in an apparatus which is obtaining said image; syncing the vibration with the camera shutter; and compensating shutter speed based on the blur compensation.

Welding cameras, welding helmets, welding masks, and associated display systems are described herein that utilize darkening or attenuating filters in conjunction with long-exposure imaging to capture flicker-free video of a welding process. Example embodiments include one or more of a darkening filter, an image sensor to capture long-exposure images as frames of a video, an optical image stabilization subsystem, a data storage to store video, and an electronic display to display the video. For example, captured images may be displayed on an electronic display within the welding mask without risk of overexposure of ultraviolet radiation to the operator. In some examples, dual electronic displays are used to display different images to each eye of the operator to provide a stereoscopic video feed.

Provided is a lens module, including a lens barrel, a lens group and a light-shading plate. The lens group at least comprises a first lens and a second lens. The light-shading plate is sandwiched between the first lens and the second lens. The first lens includes a first optical portion, and a first peripheral portion, which includes a first planar surface extending from an outer edge of the first peripheral portion, a recess portion connected to the first planar surface, and a second planar surface connected to the recess portion. The light-shading plate includes a third planar surface partially attached to the first planar surface, a protruding portion protruding from the third planar surface, and a fourth planar surface extending from the protruding portion towards the optical axis. The protruding portion is attached to the recess portion, and the second planar surface and the fourth planar surface are spaced apart.

An apparatus is disclosed which is to identify a feature of an image captured from a first focal plane; determining a focus position relative to the first focal plane; and to determine an aperture setting. At the focus position and the aperture setting, a depth of field is provided. The apparatus may be further configured to determine at least one of a second plane and a third plane relative to the first focal plane. At the focus position and the aperture setting, the at least one of the second plane or the third plane is in focus.
